Hello team!
Let's comment to the functions, that there will be library documentation?)

I fetch 10 images per time.

var browser = SKPhotoBrowser()
    override func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
        let cell = collectionView.cellForItemAtIndexPath(indexPath) as! GirlCollectionViewCell

        let originImage = cell.ivGirl.image // some image for baseImage
        browser = SKPhotoBrowser(originImage: originImage!, photos: images, animatedFromView: cell)
        browser.delegate = self
        browser.initializePageIndex(indexPath.row)
        presentViewController(browser, animated: true, completion: {})
    }

The browserViewController have shown 10 images, and when I swipe to 10/10 image, I fetch another 10 images in this method:

func didShowPhotoAtIndex(index: Int) {
        print("didShowPhotoAtIndex:\(index)")
        if index + 1 >= self.girlList.count {

            RequestManager.getGirlList(self.index, onSuccess: { (girlList) -> () in
                if girlList.count > 0 {
                    for girl in girlList {
                        let photo = SKPhoto.photoWithImageURL(girl.url)
                        photo.shouldCachePhotoURLImage = false // you can use image cache by true(NSCache)
                        self.images.append(photo)
                    }
                    self.browser.reloadData()
                    self.browser.updateToolbar()
               // ...here's do something else..
                } else {
                    self.collectionView!.mj_footer.endRefreshingWithNoMoreData()
                }
            })
        }

    }

but when I swipe to 10/10 image, the toolNextButton does not enable and the number 10/10 does not update to 10/20.
Please give me some advice.

i download the project but failed to find the SKPhotoBrowser.framework

1、
self.displayCloseButton = false// has no effects
self.enableSingleTapDismiss = true

2、Counld you add a pagecontrol at the bottom?

3、init(originImage: UIImage, photos: [SKPhotoProtocol], animatedFromView: UIView)
should add a similar method originImages: [UIImage], which can be Zoom in originImage?

Wait for you answer...

After tapping the share button and selecting the mail or sms share extensions, the app systematically crashes when dismissing the view controller

I saw the delete function. But I want to offer a different resolution. If another developer need a function delete images, it is best to make subclass () and there to override this feature. Since we can not guess where to store the image. I show you my solution

This is in SKPhotoBrowser

public func deleteButtonPressed(sender: UIButton) {

    }

    public func deleteImage() {
        if photos.count > 1 {
            photos.removeAtIndex(currentPageIndex)
            gotoPreviousPage()
            updateToolbar()
        } else if photos.count == 1 {
            dismissPhotoBrowser()
        }
        reloadData()
    }

This is a SKPhotoBrowser subclass

class ImageBrowser: SKPhotoBrowser {

    override func deleteButtonPressed(sender: UIButton) {
        print("ImageBrowser")
        let userDefault = NSUserDefaults.standardUserDefaults()
        let documents = "documents"
        let deleteController = UIAlertController(title: nil, message: "Вы действительно хотите удалить документ?", preferredStyle: .Alert)
        deleteController.addAction(UIAlertAction(title: "Нет", style: .Cancel, handler: nil))
        deleteController.addAction(UIAlertAction(title: "Да", style: .Destructive, handler: { (action) -> Void in
            var allDocuments = [DocumentEntity]()
            if let data = userDefault.objectForKey(documents) as? NSData {
                allDocuments = (NSKeyedUnarchiver.unarchiveObjectWithData(data) as? [DocumentEntity])!
            }
            allDocuments.removeAtIndex(self.currentPageIndex)
            let newData = NSKeyedArchiver.archivedDataWithRootObject(allDocuments)
            userDefault.setObject(newData, forKey: documents)
            userDefault.synchronize()
            self.deleteImage()
        }))
        presentViewController(deleteController, animated: true, completion: nil)
    }
}

And we can to use this subclass like

 let imageBrowser = ImageBrowser(photos: imageArray)
        imageBrowser.delegate = self
        imageBrowser.isForceStatusBarHidden = true
        imageBrowser.displayDeleteButton = true
        imageBrowser.initializePageIndex(indexPath.row)
        presentViewController(imageBrowser, animated: true) { () -> Void in
        }

I checked it and it fine works. What do you think about it?

As you can see from the image above, I have manually dragged the SKPhotoBrowser code into my clean project, but it is not able to recognize the SKPhotoBrowser module for some reason. Any guidance on this?

If a photo has long caption, it goes over photo, an uitextview with maximum line option would be better for captions.

        var images = [SKPhoto]()
        for image in prod.getImages() {
            let photo = SKPhoto.photoWithImageURL(image.fullHdUrl)
            images.append(photo)
        }
        // create PhotoBrowser Instance, and present.
        let browser = SKPhotoBrowser(photos: images)

fatal error: array cannot be bridged from Objective-C

by default, single tap or swipe will let status bar, toolbar and close button disappear.
but if enable single tap dismiss, and use navigationcontroller, when the status bar, toolbar and close button are disappeared, and tap the screen, it will show a statusbar & navigationbar 's height transition, it's ugly.

so i think if single tap dismiss is enabled, dont hide the status bar, toolbar and close button when singtap or swipe

For the images I am using double-tap to zoom just moves the image down a bit, but doesn't zoom in.

I have seen it work in the example application, so I am not sure what is wrong. I'll investigate more and followup here (will submit pull request if i find a solution).

Is there any possibilities to save picture into phone collection? For example add "save" button or anything else?

Thank you. Nice project.

Can you add a method to load more photos after browser presented.

Something like

browser.appendPhotos([SKPhoto])
browser.reloadData()

1. You share or cancel the share.
2. When you slide the picture to dismiss, it shows the picture twice.

Is it possible to make new pod release to reflect last changes? @krummler @alexsanderkhitev

Hi, I need use library with my NavigationController (below Navigation Bar and above my custom Toolbar).
Is any way to do this?

I used 1.8.6 , it works fine.
But since I updated to the new version （1.8.8）, an error occurred
var skPhotos = [SKPhoto]()
let photoDatas = self.item.photos
do{
for photoData in photoDatas{
let data = try photoData.getData()
skPhotos.append(SKPhoto.photoWithImage(UIImage(data: data)!))
}
}catch{
}
let skPhotoBrowser = SKPhotoBrowser(photos: skPhotos)//Throw that error! Fatal Error: Array cannot be bridged from Objective-C

Hi,

I have images in my collection view which I get from (Facebook) JSON. If I write self.images.append(SKPhoto.photoWithImage(imageView.image!)), with imageView.image! as my image from JSON data, the Photo Browser works, but it doesn't work properly. For example: when I click on an image, it sometimes shows the next/another image and the displayCounterLabel doesn't give the correct information (the total count is wrong, the count of the selected photo is wrong, it says it's the last photo when there're still photos left).

If I don't write self.images.append(SKPhoto.photoWithImage(imageView.image!)) in my code, when I click a photo, it first seems like it's gonna work, but then soon (when the view isn't completely loaded yet) there's an error, saying: "Array index out of range"...

Can you please help me as soon as possible?

If I have to provide more code or something, please let me know!

Thanks in advance!

Nice project. Thank you! The didShowPhotoAtIndex delegate is marked as a required. I think it should be marked as optional.

I really like the feature of swipe to dismiss, but some people are more familiar with single tap to dismiss the browser, maybe just in my country?
Will you guys add this feature? So people can swipe to dismiss, or tap to dismiss, or both.

Hi,

This is not an issue just a quick question. Is there a way to have the entire project in Portrait and only detect if SKPhotoBrowser is the view and change it to UIInterfaceOrientationMask.All? Something like this:

override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
        super.supportedInterfaceOrientations()
        if presentedViewController?.isKindOfClass(SKPhotoBrowser) != nil {
            return UIInterfaceOrientationMask.All
        } else {
            return UIInterfaceOrientationMask.Portrait
        }
    }

Unfortunately this doesn't work.

This is my info.plist:

<key>UISupportedInterfaceOrientations</key>
    <array>
        <string>UIInterfaceOrientationPortrait</string>
    </array>

Many thanks,

I used this library but when I click on an image from the collectionView it does not show the correct image.

and im using the same images as the example.

I have a UICollectionViewController subclass where each cell is a UIImageView (similar to your example project). However, my image view's contentMode is set to ScaleAspectFit (because my images may have different sizes). Thus, my sender frame is not the same as my image view's frame.

When I dismiss the SKPhotoBrowser view controller the animation is incorrect, it scales the image to the view's frame, stretching the image, before disappearing.

I´ve just installed pod and there is some issues with selectors on Xcode 7.2.1

I try to using this image with url https://www.thuthuatweb.net/wp-content/uploads/baiviet/2014/01/windows-phone-loading-animation.png but the demo does not show anything.
Could you check this?

Hi! First of all thanks for such control!

There is a bug when trying to zoom a small image with double tap
If you try to zoom such image with gesture everything is fine (it just not scale)

Here is an example

Only the first picture is shown as someone clicked on it, but the collection view doesn't show all the pics on it, as it would do if the pics were stored locally (which worked fine, just when I changed to URL they don't appear anymore)

Im using a GET to get the URLs in an array, and then put them in the images array, with the caption and the URL for the picture, and then I set the delegate and data source to self, but they still don't appear.. :(

let browser = SKPhotoBrowser(originImage: originImage, photos: images , animatedFromView: cell)

if press close button before image was loaded - it leads to crash of the module.
simple solution is:
in file SKPhotoBrowser.swift:
public func performCloseAnimationWithScrollView(scrollView: SKZoomingScrollView) {

change :

 resizableImageView.image = scrollView.photo?.underlyingImage.rotateImageByOrientation() ?? resizableImageView.image 

to:

        if scrollView.photo?.underlyingImage == nil {
            resizableImageView.image = UIImage()
        } else {
        resizableImageView.image = scrollView.photo?.underlyingImage.rotateImageByOrientation() ?? resizableImageView.image 
        }

How can I use a custom cache and downloader? I use Kingfisher as my MainImageManager, so when loading a new image from url, both SKPhotoBrowser and Kingfisher downloading the photo.

P.S:
I had one other problem: I have a floating view (like FAB button), when dismissing a photo by swipe, it's animation covers the floating view till it's fit in the source rect. How can I manage this? (I've tried to send the animating view to back of the floating view, but in another view I have two floating buttons that this workaround won't work.)

Also when a photo is dismissed by swipe where source rect is not in view, the animation is weird (flickering till disappears), I've managed it by manipulating the SKPhotoBrowser class, but I just wanted to know do you have any straight solution for that?

Thanks! 😊

If you click slowly, when gallery reached edge it stops, but if you spam fast it goes out of gallery, you can check video.

If the image of collectionview item is not loaded, such as load failed or the web image does not exist, now touch the image that not loaded then close SKPhotoBrower, it will crash on line 884 of SKPhotoBrower.swift.

This error is in the photos argunment, in the SKPhotoBrowser

Adding facebook gallery dismiss effect would be nice, photo tracks your finger on x and y, while all ui except photo lose alpha with your movement and you can see view controller which one is behind, and the view controller at behind doesn't show the photo which you are currently holding, just a placeholder. Then when you drop photo it animates to position at behind view controller.

Wrong zoom when touch the black area. But I found a solution to the problem. I'm counting on interest clicking on the black area and bear the interest on the image. Also, the image may have a height greater than that of the device in pixels. So I decided to divide the height of the screen into two. Further, if a touch on the black area was in the range of less than half of the screen, Y is equals 0, if more than half of the screen, Y equals image height in pixels. It need to add in SKZoomingScrollView. I hope that it helps you. Thanks

I use a collectiongView in UItableViewCell.

func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {

        var images = [SKPhoto]()
        for _url in vo!.photos {

        browser.initializePageIndex(indexPath.row)

        NSNotificationCenter.defaultCenter().postNotificationName("SHOW_PHOTO_BROWER", object: browser)
    }

I handle the notification in tableviewcontroller:

NSNotificationCenter.defaultCenter().addObserver(self, selector:"showPhotoBrower:", name:"SHOW_PHOTO_BROWER", object: nil)

func showPhotoBrower(note:NSNotification){
        weak var browser = note.object as? SKPhotoBrowser
        presentViewController(browser!, animated: true, completion: {})
    }

If I click one collectionviewcell and just close SKPhotoBrowser, it is worked well.
I watch next photo in SKPhotoBrowser then close it, it can not be destory.

SKPhotoBrowser:

deinit {
        pagingScrollView = nil
        NSNotificationCenter.defaultCenter().removeObserver(self)
    }

This function can not be reached.
Where do I use the wrong？

Thx ur project.

when rotate to landscape from portrait or vise versa, Image zoom to max than rest to minimum zoom.

After device rotation if you change between images all are good but current image frame for initial state (after first rotation) is not good, have to be refreshed

I ported over the action button functionality from IDMPhotoBrowser, but didn't realize they were using deprecated code. I'll update & submit a pull request to get rid of the warnings.

Do u have a plan to add a Delete icon in right of nav bar ?
If not , I will add it.

when button hidden, horizontal swipe sometime not working. bug happens when swiping to the last photo.
