Hi,

When a segment is selected, I'm looking for a way to set a different text color and indicator color.
I checked the code, the indicator is the same as text color.

So can you add an additional indicator color attribute, which will override the tint color?

Thanks!

Should we move isImageMode property to header file so that we could make this property to YES and do more further configurations?

• (void)setSegmentedControl:(DZNSegmentedControl *)segmentedControl
  {
  objc_setAssociatedObject(self, &segmentedControlKey, segmentedControl, OBJC_ASSOCIATION_ASSIGN);

  if (segmentedControl) {
  [self addObserver:self forKeyPath:contentOffsetKey options:NSKeyValueObservingOptionNew context:&observerContext];
  [segmentedControl addTarget:self action:@selector(dzn_didChangeSegement:) forControlEvents:UIControlEventValueChanged];
  }
  else if (self.segmentedControl) {
  [self removeObserver:self forKeyPath:contentOffsetKey context:&observerContext];
  [segmentedControl removeTarget:self action:@selector(dzn_didChangeSegement:) forControlEvents:UIControlEventValueChanged];
  }

  self.scrollOnSegmentChange = YES;
  }

else if (self.segmentedControl) {

self.segmentedControl always return nil

Assuming I have a DZNSegmentedControl with previous and next, in my case I should be able to click next more than one time, the default behaviour of DZNSegmentedControl will not recognise the success if second click is on same segment. So how to deal with that?

I m trying to directly add the control onto the view but without success instead of connect it to the table header.
Any help?
Thanks

I am trying to use this Control on a Storyboard. My view controller is arranged this way:
UIViewController > UIView (Main) > UIView (Gradient BG) > UIView (DZNSegmentedControl)

If I push that view controller and then pop it, the app crashes with this log message (note: zombies enabled):

*** -[UIView release]: message sent to deallocated instance 0x7fedeae64ac0

If I remove the class name from that view, the app will no longer crash.
If the view assigned as DZNSegmentedControl is not inside a second view (the gradient), but is inside the main view, it also will not crash.

I created a sample project that demonstrates this.
The project has a second branch called programmatically, when I keep the inner view set as a regular UIView and then add a DZNSegmentedControl inside it programmatically. that way the app will not crash.

No working: _control.font = UIFont.systemFontOfSize(20) in swift

what is the matter?
thank you

Hi, @dzenbot Why did not you update the version of Pod after fixing some bugs? Please update the version for the current master if it is necessary.

Set Methods should not be called in itself setting.
This may crash when setting it another time.

- (void)setItems:(NSArray *)items
{
    if (_items) {
        [self removeAllSegments];
#pragma mark This should not be called this way.
//        [self setItems:nil];
    }

    if (items) {
        _items = [NSArray arrayWithArray:items];
    }

    [self configure];
}

It's crash point could be here:
By the way, I'd like to change buttons to newButtons for safety.

- (NSArray *)buttons
{
//--- This Line
    NSMutableArray *newButtons = [NSMutableArray new];
//---
    for (UIView *view in self.subviews) {
        if ([view isKindOfClass:[UIButton class]]) {
            [newButtons addObject:view];
        }
    }
    return newButtons;
}

Hi, can we get a new podspec update for the current master?

There are a couple ways this could be implemented.

• An @property on each instance of DZNSegmentedControl
• An optional delegate method that asks for a custom NSNumberFormatter for each segment index. This would allow, for example, number values to be displayed in one segment and currency values in another segment.

Which do you think would be best?

Hi
i tried to run my app in xcode beta 6 & ios 10 simulator (iphone 5)
DZNSegmentedControl doesn't show right

Great repo 👍
I just wondering is there an easy way to glue the segmentControl below navigation bar while scrolling?
It will be great if there is an API to accomplish this.

DZNSegmentedControl should support swipe function.

Is it possible to make it work in a UIView? So I can fix it at the top, and when the UITableView is scrolled the segment view will be still visible.

I tried but couldn't get it to work.

when i init control as follow

 _timeControl = [[DZNSegmentedControl alloc] initWithItems:@[NSLocalizedString(@"日榜", @""),
                                                                    NSLocalizedString(@"周榜", @""),
                                                                    NSLocalizedString(@"总榜", @"")]];
_timeControl.tintColor=FZLightColor;

when calling

 [self.timeControl setSelectedSegmentIndex:2 animated:YES];

segmentIndex's tintColor is not FZLightColor

when i init control as follow

_timeControl = [[DZNSegmentedControl alloc] initWithItems:@[NSLocalizedString(@"day", @""),
                                                                    NSLocalizedString(@"week", @""),
                                                                    NSLocalizedString(@"all", @"")]];
_timeControl.tintColor=FZLightColor;

that will effect when calling setSelectedSegmentIndex:animated

Is it possible to use a particular colour for the indicator, and another for the text? In my case the indicator colour needs to be really bright, which won't work for text.

cannt init

Thanks for great work!
I have a question
Is it possible create DZNSegmentedControl in custom view instead UITableHeaderView?

I'm trying to set the hairline color with [UIColor colorWithRed:142/255.0 green:8/255.0 blue:35/255.0 alpha:1.0];
This doesn't change the color at all.

Hey, @dzenbot ，
Your segment control is great. I think I can make it tracking a scrollView like this. You'd like me try?

Currently the segmented title is clipped when it is longer than width even though they have height to expand due to a fixed set on numberOfLines = 1 (showsCount: false, I don't want to show count).

Is there a way to make this changes without forking out? The button in the segmentViews are private variables.

Dears,

im adding the DZNSegmentedControl as a subview, the height was ok, filling the whole parent view. but after the last, the segmented is cut into half to set the font height.

setting the height explicitly like this
self.segmentedControl.height = self.segmentedView.frame.size.height;
is causing the segnemted not filling the whole view again after rotation

thank you

Hi, is there a way for me to set the text color when i select the segment?
The text color dimmed when I used

    func pageViewController(pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [AnyObject], transitionCompleted completed: Bool) {
        segmentSubviews.selectedSegmentIndex = myPageViewController.viewControllers[0].pageIndex
    }

I've upgraded an app to IOS8 and DZNSegmented Control now crashes

* Terminating app due to uncaught exception 'NSRangeException', reason: '* -[__NSArrayM setObject:atIndex:]: index 2 beyond bounds for empty array'

-[__NSArrayM setObject:atIndex:] + 458
-[NSMutableArray setObject:atIndexedSubscript:] + 48
-[DZNSegmentedControl setCount:forSegmentAtIndex:] + 649

It seems that self.counts[segment] = count; in - (void)setCount:(NSNumber *)count forSegmentAtIndex:(NSUInteger)segment is the culprit as the array is init but has a count of 0.

I suggest adding changing - (void)setItems:(NSArray *)items to this:

- (void)setItems:(NSArray *)items
{
    if (_items) {
        [self removeAllSegments];
    }

    if (items) {
        _items = [NSArray arrayWithArray:items];

        if (self.counts)
            self.counts = nil;

        self.counts = [[NSMutableArray alloc] initWithCapacity:items.count];
        for (int i = 0; i < items.count; i++) {
            [self.counts addObject:@(i)];
        }

        [self insertAllSegments];
    }
}

Hi,
i have tried to use your project in my app, in viewDidLoad i do this:

NSArray *items = @[@"Tweets", @"Following", @"Followers"];

DZNSegmentedControl *control = [[DZNSegmentedControl alloc] initWithItems:items];
control.tintColor = [UIColor blueColor];
control.delegate = self;
control.selectedSegmentIndex = 1;

but the app crash when set the delegate, and give me this error:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', 
reason: '-[ViewController positionForBar:]: unrecognized selector sent to instance

how i can solve?

Adding this line to my podfile

pod 'DZNSegmentedControl', '1.2'

causes this error when pod install analyzes dependencies.

[!] Unable to satisfy the following requirements:

- `DZNSegmentedControl (= 1.2)` required by `Podfile`

I understand the meaning of the error but wasn't the pod updated to version 1.2?

I'm implementing animation in my app and the segmented control needs to fade in/out, but for some strange reason I can't alter the alpha property.

Is there a way to use uiimage as the titles?

title显示不了多行！

I'm trying to set the font to a smaller size so that the entire string will fit into the control. Currently, if you run off the edge of the provided area, the text just gets cutoff.

It would be great if you could either change the font size manually, or do some multi-line adjustment if the text is going to run outside the bounds.

Right now, there are no delegate methods; the control is given the attributes before it needs them. So far this works fine. But as more attributes are supported it might become verbose to call
-set[Attribute]:forSegmentIndex:
for every attribute on every segment. What are your thoughts? (Not trying to criticize your implementation, which I think works well right now. Just something to consider for the future.)

In ScrollView-Example DEMO, I set self.segmentedControl.autoAdjustSelectionIndicatorWidth = YES; then I draging scrollView, it appear like this...

It might be useful to use this segmented control without any count labels.
@charles-rouchon has a decent modification about this. You should send a PR, allowing counts and not.

Hey,

since 1.3.1 I have the issue, that the first row of the UITableView is hidden behind the DZNSegmentedControl.
After switching between the groups the first row is visible.

I add the header to the tableView after reloadData

The 'font' property don't change the count string font size.

[attributedString addAttribute:NSFontAttributeName value:[UIFont fontWithName:self.font.fontName size:19.0f] range:[string rangeOfString:count]];

Hey,

As usual great work :) I was wondering if we can setup a UISegmentedControl in IB and have it conform to the DZNSegmentedControl class? I tried it I can't set its class in IB

I'm trying to use a tall selection indicator as shown in the graphic below. However, when a segment is selected, the indicator stays behind the titles but then covers them after the animation completes. I tried commenting out the line [self bringSubviewToFront:_selectionIndicator]; in -layoutSubviews but this did not fix the problem.
