Fatal error when using coachMarkWillLoadForIndex

Hi,

I'm implementing func coachMarksController(coachMarksController: CoachMarksController, coachMarkWillLoadForIndex index: Int) -> Bool {}

however if I return false i get:

fatal error: unexpectedly found nil while unwrapping an Optional value

/// Show the next coach mark and hide the current one.
private func showNextCoachMark(hidePrevious hidePrevious: Bool = true) {
self.currentIndex++

    // if `currentIndex` is above 0, that means a previous coach mark
    // is displayed. We call the delegate to notify that the current coach
    // mark will disappear, and only then, we hide the coach mark.
    if self.currentIndex > 0 {
        self.delegate?.coachMarksController(self, coachMarkWillDisappear: self.currentCoachMark!, forIndex: self.currentIndex - 1)

currentCoachMark Instructions.CoachMark? nil None

I only have one CoachMark.

Any ideas?

delay function is never used

the function

public func delay(delay:Double, closure:()->())

in Instructions.swift is never used within the project.

Wrap or remove access to `UIApplication.sharedApplication()`

The reason is:

+ (UIApplication *)sharedApplication NS_EXTENSION_UNAVAILABLE_IOS("Use view controller based solutions where appropriate instead.");

Access to UIApplication.sharedApplication() unavailable inside iOS extensions and because of this library cannot be used for instance for guide inside custom keyboard.

Changing orientation causes multiple marks or causes mark to not be erased.

Hello!

Thanks so much for the work on this library -- it really looks great.

My app requires an orientation change mid-tour and it gets a little screwy when changing orientation while a mark is showing. In my app it causes whatever mark was showing to never disappear.

In the sample app if you go to the 'TransitionFromCode' screen and change orientation while a mark is showing, this is what you get:

Thanks again!

Restarting the marks

I'm having an issue where I run through my coach marks and then try to do it again and nothing loads. Is there an easy way to rewind to the start?

Customizing view cutout

Hey,

Thanks a lot for this library. I was wondering if you could tell me how to customize the cutout path. Here's a screenshot of what I'm getting.

http://imgur.com/q26iERN

I would really like to "cut" the three edges that are visible in my cutout. On the bottom and on the right side of my visible view, I have black bars. And at the top, I have a yellow bar. I've also got a small yellow portion at the bottom-right portion of the visible view. I would like to customize the visible view cutout so that all I see is the center yellow part. I just need to cut the little bits that are on the sides, to make it look cleaner, and uni-coloured. How can I do that ?

Merci beaucoup de nous fournir cette ressource géniale. Cela me fait économiser énormément de temps pour mon premier project sérieux avec Swift et iOS.

Merci,

Adding on TabBarController

Hi. how can i add on tabbar controller? thanks you.

Skipping already shown CoachMarks

I wanted to show a coachMark, leave my current controller, come back to it and skip the coachMark that I have already shown to my user. I wanted to make a good use of this delegate function:
func coachMarksController(coachMarksController: CoachMarksController, coachMarkWillLoadForIndex index: Int) -> Bool { if index <= defaults.integerForKey(GlobalConstants.skipProfileWalkthrough) { return false } return true }
However, it was crashing on this line in your library:
self.delegate?.coachMarksController(self, coachMarkWillDisappear: self.currentCoachMark!, forIndex: self.currentIndex - 1)
with the following error:
fatal error: unexpectedly found nil while unwrapping an Optional value
It was pretty much trying to wrap self.currentCoachMark that was nil for some reason.
I fixed it myself on your library and took some notes. Attached you can see the notes I took and the fixes I made on your library:

Also I am not using your delegate function coachMarkWillDissappear anymore, I do not think that it is working fine, instead I am doing it like this:

How to add two buttons in coachMark?

Skip View Location

How do I change the location of CoachMarkSkipDefaultView from right top corner to left top corner? Or use the frame of another object as my skip view?

Any help would be greatly appreciated!

Thanks!

Crash when first displayed.

Cutouts appear in the wrong place when the In Call Status Bar is displayed

Coach marks work well normally but if a call comes in (you can do this in the simulator by toggling the In Call Status Bar) the cutout won't be in the right place anymore. Perhaps the cutout can be shifted when the status bar appears?

Prevent tap on custom CustomCoachMarkBodyView and coachMark?

Hi,

is is possible to prevent the tap events on my coach marks? I just want to show the walkthrough and it shouldn't be possible to tap on the highlighted button for example.

I also wonder why my overlay tap is not working properly. When I tap on the hint text on my custom body view I can't go a step further. I already set up the property "allowOverlayTap" to true and disabled user interaction in my custom body view class on any view. It only works when I tap on an empty area but not if tap on the hint text?

Thank you in advance!

When creating a new coachMark for navigation bar button item CoachMarkArrowView is not showing correctly

I have created four coachMarkView's which are pointing to a navigationBarTitle, leftNavigationBarButtonItem, rightNavigationBarButtonItem, and a simple view. I have done something like:

func numberOfCoachMarksForCoachMarksController(coachMarksController: CoachMarksController) -> Int {
        return 4
    }

    func coachMarksController(coachMarksController: CoachMarksController, coachMarksForIndex index: Int) -> CoachMark {
        switch(index) {
        case 0:
            return coachMarksController.coachMarkForView(self.navigationController?.navigationBar) { (frame: CGRect) -> UIBezierPath in
                return UIBezierPath(rect: frame)
            }
        case 1:
            return coachMarksController.coachMarkForView(self.viewAddButton)
        case 2:
            let leftBarButton = self.navigationItem.leftBarButtonItem! as UIBarButtonItem
            let viewLeft = leftBarButton.valueForKey("view") as! UIView
            return coachMarksController.coachMarkForView(viewLeft)
        case 3:
            let rightBarButton = self.navigationItem.rightBarButtonItem! as UIBarButtonItem
            let viewRight = rightBarButton.valueForKey("view") as! UIView
            return coachMarksController.coachMarkForView(viewRight)
        default:
            return coachMarksController.coachMarkForView()
        }
    }

    func coachMarksController(coachMarksController: CoachMarksController, coachMarkViewsForIndex index: Int, coachMark: CoachMark) -> (bodyView: CoachMarkBodyView, arrowView: CoachMarkArrowView?) {

        let coachViews = coachMarksController.defaultCoachViewsWithArrow(true, arrowOrientation: coachMark.arrowOrientation)

        switch(index) {
        case 0:
            coachViews.bodyView.hintLabel.text =  Constants.InstructionNavigation
            coachViews.bodyView.nextLabel.text = self.nextButtonText
        case 1:
            coachViews.bodyView.hintLabel.text = Constants.InstructionAddButton
            coachViews.bodyView.nextLabel.text = self.nextButtonText
        case 2:
            coachViews.bodyView.hintLabel.text = Constants.InstructionLeftBarButton
            coachViews.bodyView.nextLabel.text = self.nextButtonText
        case 3:
            coachViews.bodyView.hintLabel.text = Constants.InstructionsRightBarButton
            coachViews.bodyView.nextLabel.text = self.nextButtonText
        default: break
        }

        return (bodyView: coachViews.bodyView, arrowView: coachViews.arrowView)
    }

What I am getting in output is:

Navigation title is all good coz is in center i think please look here http://tinyurl.com/j2kv86t

But when showing coachMark for left or right navigation button item it looks like,
LeftBarButtonItem: http://tinyurl.com/ztoswd3
RightBarButtonItem: http://tinyurl.com/jgabyj7

Sample Objective-C

Hi,

Have you a little sample of implementation in Objective-C ?

Thanks

CoachMarkBodyView shows on the end of the window

Hey guys,

I'm trying to create a coachmark to a view that has this hierarchy:

UIScollView -> UICollectionView -> UICollectionViewCell -> UIView

When coach marks tries to show it shows below the window, when it should show up on my view.

I needed to use the "gapBetweenCoachMarkAndCutoutPath" to workaround this problem.

Fatal Error: Instructions could not be properly attached to the window, did you call `startOn` inside `viewDidLoad` instead of `ViewDidAppear`

attachToViewController: Instructions could not be properly attached to the window, did you call startOn inside viewDidLoad instead of ViewDidAppear?

The message is shown from
private func computeSegmentIndexForLayoutDirection(layoutDirection: UIUserInterfaceLayoutDirection) -> Int {
let pointOfInterest = coachMark.pointOfInterest!
var segmentIndex = 3 * pointOfInterest.x / instructionsTopView.bounds.size.width

    if layoutDirection == .RightToLeft {
        segmentIndex = 3 - segmentIndex
    }

    return Int(ceil(segmentIndex))
}

Enhancement: use Instructions from within Objective-C file

Would be great if this support could be added!

reset in completion from stop() is a problem.

First of all thank your for this nice component. It's very useful.

I had a problem when starting immediately a new set of coaches after stoping the first stop() function.
I added a closure and now I call startOn() again inside only when I receive a callback from this new stop. Maybe you have a better solution.

/// Stop displaying the coach marks and perform some cleanup.
public func stop(onComplete: (() -> Void)? = nil) {
    UIView.animateWithDuration(self.overlayFadeAnimationDuration, animations: { () -> Void in
        self.overlayView.alpha = 0.0
        self.skipViewAsView?.alpha = 0.0
        self.currentCoachMarkView?.alpha = 0.0
    }, completion: {(finished: Bool) -> Void in
        self.skipView?.skipControl?.removeTarget(self, action: "skipCoachMarksTour:", forControlEvents: .TouchUpInside)
        self.reset()
        self.detachFromViewController()

        // Calling the delegate, maybe the user wants to do something?
        self.delegate?.didFinishShowingFromCoachMarksController(self)

        onComplete?()

    })
}

Multiple coachmarks when tapping overlayview rapidly.

First off, great project!
Second: When the user taps the overlayview quickly, showNextCoachMark gets called instantly multiple times and one or more coachmarkviews get stuck on the screen.
I also did a quick fix, feel free to use it if You want to.

Add a second gesture recognizer to the overlayView that detects double taps: (no need for it to have an action)

private lazy var doubleTapGestureRecognizer: UITapGestureRecognizer = {
        let gestureRecognizer = UITapGestureRecognizer(target: self, action: "handleDoubleTap:")
        gestureRecognizer.numberOfTapsRequired = 2

        return gestureRecognizer
    }()

Make sure singe tap gesture recognizer only detects tap when double tap fails:

private lazy var singleTapGestureRecognizer: UITapGestureRecognizer = {
        let gestureRecognizer = UITapGestureRecognizer(target: self, action: "handleSingleTap:")
        gestureRecognizer.requireGestureRecognizerToFail(self.doubleTapGestureRecognizer)

        return gestureRecognizer
    }()

Add double tap gesture recognizer where the single tap recognizer is added:

var allowOverlayTap: Bool {
        get {
            return self.singleTapGestureRecognizer.view != nil
        }

        set {
            if newValue == true {
                self.addGestureRecognizer(self.singleTapGestureRecognizer)
                self.addGestureRecognizer(self.doubleTapGestureRecognizer)
            } else {
                self.removeGestureRecognizer(self.singleTapGestureRecognizer)
            }
        }
    }

Bug fixed.

Objective-C

Are there any plans to release this control for objective-c?

Looks fantastic, by the way!

showNextCoachMark has bad logic causing crash

I am conditionally hiding my first coach mark. When I do hide it, my app crashes because of this line of code. It looks like self.currentIndex is increment before it is checked for 0, so the if statement will run 100% of the time.

private func showNextCoachMark(hidePrevious hidePrevious: Bool = true) {
        self.currentIndex += 1

        // if `currentIndex` is above 0, that means a previous coach mark
        // is displayed. We call the delegate to notify that the current coach
        // mark will disappear, and only then, we hide the coach mark.
        if self.currentIndex > 0 {
            self.delegate?.coachMarksController(self, coachMarkWillDisappear: self.currentCoachMark!, forIndex: self.currentIndex - 1)

            if hidePrevious {
                self.coachMarkDisplayManager.hideCoachMarkView(self.currentCoachMarkView, animationDuration: self.currentCoachMark!.animationDuration) {
                    self.removeTargetFromCurrentCoachView()

                    if self.currentIndex < self.numberOfCoachMarks {
                        self.createAndShowCoachMark()
                    } else {
                        self.stop()
                    }
                }
            } else {
                if self.currentIndex < self.numberOfCoachMarks {
                    self.createAndShowCoachMark()
                } else {
                    self.stop()
                }
            }
        } else {
            self.createAndShowCoachMark()
        }
    }

Rotating device causing index out of range.

The following is my implementation of the coachMarksForIndex data source function.

func coachMarksController(coachMarksController: CoachMarksController, coachMarksForIndex index: Int) -> CoachMark {
            let instruction = self.instructions[index]
            return coachMarksController.coachMarkForView(instruction.pointOfInterest)
}

As you can see I am accessing an array to determine the point of interest for each CoachMark.

This works as expected the first time you start the coachMarksController. However, during a rotation of the device (iPad Pro) the data source method fires, passing '-1' as the index. Obviously causing the index out of range exception.

Please note I am rotating the device after the coachMarksController finishes the animation; there are no coachMarks on screen.

I originally thought I was doing something wrong, however I am slightly confused as to why the data source function is firing when there are no coachMarks on screen.

I then realised that after running the coachMarkController once, I was not able to run it again. (I soon saw that you have fixed this #58 but not released it?)

Any ideas?

Add ability to control blur radius of overlay view

Yes, it is not so easy but it is possible with this approach: https://github.com/shergin/Bluuur/blob/master/Bluuur/Classes/MLWLiveBlurView.m

Or, alternativly, add ability to set custom overlay view.

Working perfectly in iOS 9 but Screen goes black in iOS 8

"walthroughs" is misspelled in the repo description. ;0

Looks like an awesome project, btw.

Instructions was compiled with optimization - stepping may behave oddly; variables may not be available.

When I'm implementing func coachMarksController(coachMarksController: CoachMarksController, coachMarkWillLoadForIndex index: Int) -> Bool I get a runtime error:
Instructions was compiled with optimization - stepping may behave oddly; variables may not be available.

the delegate is set to self.

Make coachmark appear above the view

Hi, I'm trying to get the coachmark to appear above the view I'm trying to point to, but am having a hard time figuring out how to do so. I realize that for some views the coachmark automatically appears at the top, but in my case it is not and is being presented off the screen.

Rename `datasource` to `dataSource`

The variant dataSource is more convenient on iOS.

Thanks!

Rotating device duplicates marks

Rotating the device during instructions from portrait to landscape (or the other way round) duplicates the coach marks and messes up the instructions. Reproduced by running the example code.

Maybe the easiest solution is to disable device rotation when instructions are ongoing but I wonder if there is a better solution.

oc version?

have oc version ?

Anyway to make use of this library in my objective-c project?

Ambiguous use of 'coachMarkForView(_:bezierPathBlock:)'

in the method:

func coachMarksController(coachMarksController: CoachMarksController, coachMarksForIndex index: Int)
    -> CoachMark {
      var coachMark : CoachMark
      switch index {
      case 0:
        coachMark = coachMarksController.coachMarkForView(self.collectionView)
      case 1:
        coachMark = coachMarksController.coachMarkForView(self.imageButton)
      default:
        break
      }
      coachMark.gapBetweenCoachMarkAndCutoutPath = 6.0
      return coachMark
  }

when I try to assign the point of interest (at case 0)

 coachMark = coachMarksController.coachMarkForView(self.collectionView)

I get the error: Ambiguous use of 'coachMarkForView(:bezierPathBlock:)_
The case 1 works fine.

computeSegmentIndexForLayoutDirection: instructionsTopView.bounds.size.width is 0, segmentIndex is +Inf

computeSegmentIndexForLayoutDirection: instructionsTopView.bounds.size.width is 0, segmentIndex is +Inf
I'm getting the error:
attachToViewController: Instructions could not be properly attached to the window, did you callstartOninsideviewDidLoadinstead ofViewDidAppear?
Although I put the startOn on viewdidappear...

有么有OC版的呢?

Multiple coaches?

This project looks awesome, but I was looking for something that supports multiple instructions on the screen at the same time. Any plans for this? Thanks in advance!

Most classes not accessible from Objective-C

Most of your classes are not accessible from Objective-C since they don't descend from NSObject. You can fix that by simply preceding their declaration with '@objc'.

Thanks!

Use with SpriteKit??

Is it possible to use this with sprite-kit? I think you can cast and skView to a UIVIew. I'll try it out but it would be great if it were a new feature!

Skip certain coachMark

Hi there. Great work on Instructions!

Is there a way to skip a certain coachMark programatically? E.g. getting access to showNextCoachMark().

My use case is:

Display keyboard during a coachMark
Wait for the user's input
Progress to the next coachMark after user has selected 'return' from the keyboard

I would like to skip the current coachMark in step 3, so the next coachMark is displayed after user 'returns'.

Show message-only coachmarks

Sometimes it is preferable to display just a text, without a next button or a separator. It seems Instructions does not support this at the moment. But I think it would be a good addition.

CochMarkView remains on screen if i touch inside cutout view

If I press back button inside cutout view, or for matter of fact any button or action. View still remains on screen. Can we add anything that can skip to next coachmarkview.?

For example, If I have small expandable cell with "see more" and I am instructing user to see more but i want next cutout to appear upon clicking on "see more" rather than on ok.

Question regarding the usage of hyphenationFactor

Hi!
Two questions please:
1.I'm interested to know what is design reason behind using hyphen word break on CoachMarkBodyDefaultView?
2. I see that hyphenationFactor's documentation states that its value should be between 0.0 to 1.0. But I see it is set to 2.0... What is the reason for this?

Help in adding Instructions Manually

Hi
Would love for some help...
I'm trying to add Instructions manually, as I'm getting some issues when trying add any Swift project to my Objective-C project (setting my pods to "use_frameworks!" is what does the problem - not related specifically to Instructions).

So I follow the instructions, but:

When adding the "Instructions.xcodeproj" it only adds this file - shouldn't I add the entire source files library?
After doing this, I was following steps 2-4, but on 4, I couldn't find the file "Instructions.xcodeproj".

What am I doing wrong?

Does it work with tableviews?

Unbalanced calls toBug: begin/end appearance transitions for <Instructions.CoachMarksController: 0x7f8e9af09af0>
