In MXPagerView class you registered self as KVO observer in - (instancetype)init:

    [self addObserver:self forKeyPath:NSStringFromSelector(@selector(contentOffset))
              options:NSKeyValueObservingOptionNew|NSKeyValueObservingOptionOld
              context:kMXPagerViewKVOContext];

    [self addObserver:self forKeyPath:NSStringFromSelector(@selector(contentSize))
              options:0
              context:kMXPagerViewKVOContext];

But in - (void)dealloc you forgot to removeObserver. This will lead to crash.

When I use MXSegmentedPager for my detail controller in a uisplitviewcontroller, I encounter the following issue.

Pulling down the view past a certain point results in the enlarged image view 'sticking' at its enlarged size. When the view is released and the header returns to normal size, the imageview is still enlarged.

This is happening in the split view sample app we looked at in a previous issue.

Hello, first let me say just thank for creating this awesome project.

I have been figthing with these issue a couple of days now, a ViewController that loads a simple segmented Pager, the first "panel" is loaded from a TableView in the storyboard, when I run the application the data stay on the view only if I do not scroll down, if for some reason I do it, then the cell erase all the labels.

Could you please, take a look and give me some advice.

Hi,

i'm trying to add your very nice library into my project but i've got an issue when i insert the mxsegmentedPager directly in the storyboard.
It seems the datasource and delegate need to be set at first place but the app failed before i can set them in my viewController.
Here is the error :

Could you help me with that ?

Thanks in advance

If I want to add a pull to refresh function, how can I do that?
Or when the header had scrolled down to the bottom(without stretched), how can I just scroll down the tableview to pull to refresh. Thanks

Hi @maxep

I have two ViewControllers loaded by MXSegmentedPage; in all this two ViewControllers can be played a video flow by the user.

When user change the current tab I have to pause the played video for the hidden tab.

I've thinked to put my logic into the ViewController waiting for a viewWillAppear/viewDidAppear call for the current selected tab and a viewWillDisappear/viewDidDisappear for the previous selected tab, but this methods aren't called right now.

Can you help me?

Thanks

First of all Thanks for the awesome library......Is it possible to create view on storyboard and then add them to the tab...or do we have to write whole ui programmatically....

I got this working last time by adding the views programmatically (not hooking up MXSegmentedPager in the storyboard). I have some pretty complex view controllers in my app, and I am trying to hook up MXSegmentedPager to an outlet in storyboard, where the top and bottom constraints change.

I have found that the segmented control needs constraints. I added this to - (HMSegmentedControl *)segmentedControl method:

    _segmentedControl.translatesAutoresizingMaskIntoConstraints = NO;
    NSDictionary *binding  = @{@"v" : _segmentedControl};
    [self addConstraints:[NSLayoutConstraint
                          constraintsWithVisualFormat:@"H:|-0-[v]-0-|"
                          options:NSLayoutFormatDirectionLeadingToTrailing
                          metrics:nil
                          views:binding]];

    [self addConstraints:[NSLayoutConstraint
                          constraintsWithVisualFormat:@"V:|-0-[v(50)]"
                          options:NSLayoutFormatDirectionLeadingToTrailing
                          metrics:nil
                          views:binding]];

which works well. But only in the case that there is no ParallaxHeader.

I am having trouble adding the constraints to the MXSegmentedPager+ParallaxHeader.m file, when a parallax header exists. No matter where I add them, things blow up.

I am using iAd in my app. Sometimes, the screen frame increases and decreases momentarily as the iAd leaves and comes back on the screen. This causes a visible double-reload of the screen, which looks awful - the screen seems to jerk and flicker.

Hi, I think I've found a bug in the latest version 3.0.1.

In my MXSegmentedPagerController subclass I have just one page when the ViewController is loaded, but after a while (when a remote feed is loaded) I need to add another page.

Even if I call self.segmentedPager.reloadData() the segmentedControl view doesn't update itself, until I manually swipe into the first item.

Somebody can help me?
Thanks.

The contentOffset changes when the iPad rotates or when the detail view of a UISplitviewController is expanded to fill the width of the screen. The change in contentOffset sets off this sequence

-[MXPagerView observeValueForKeyPath:ofObject:change:context:]
-[MXPagerView didScrollFromPosition:ToPosition:]
-[MXPagerView setIndex:]
-[MXSegmentedPager pagerView:didMoveToPageAtIndex:]

which calls:
[self.segmentedControl setSelectedSegmentIndex:index animated:NO];

So when I rotate the iPad or expand the detailView of a UISplitviewController to fill the screen, a different segment of the segmentedControl is often selected (sometimes it does not switch, but in many/most cases it does).

Nice work there. But, is it possible for me to disable the parallax. I don't want it. Thanks

Hi, i implement this cool library in my app. I implement with a UIScrollView but i have this issue. Can you help me?

Thanks!

Hello,

• can we change the height of the ParallaxHeader
• we did like this :
• first :
  segmentedPager.setParallaxHeaderView(headerView, mode: .TopFill,
  height: 300)
• then :
  segmentedPager.setParallaxHeaderView(headerView, mode: .TopFill,
  height: 600)
• But it is not work, Error:

Unable to simultaneously satisfy constraints.
    Probably at least one of the constraints in the following list is one you don't want. 
    Try this: 
        (1) look at each constraint and try to figure out which you don't expect; 
        (2) find the code that added the unwanted constraint or constraints and fix it. 
(
    "<NSLayoutConstraint:0x21dc73fb0 V:[PrcmQA.NewUserInfoView:0x21dbebe80(300)]>",
    "<NSLayoutConstraint:0x24863bfb0 V:[PrcmQA.NewUserInfoView:0x21dbebe80(>=600)]>"
)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x24863bfb0 V:[PrcmQA.NewUserInfoView:0x21dbebe80(>=600)]>

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

Thanks for your advice.

I have a MXSegmentedPager with two lists and a parallax header.

I am implementing the method

- (void)segmentedPager:(MXSegmentedPager *)segmentedPager didSelectViewWithIndex:(NSInteger)index

to change the parallax header whenever the list changes (I change the imageView's image).

I animate the change of pictures for .5 seconds to make it a bit smoother. Whenever I transition from the first tab to the second, the animation is fine. However, on certain instances, when I change from tab two to tab one, the animation doesn't work.

I logged a message whenever the animation started and when it finished and it seemed that the animation was starting twice. I then put a log at the beginning of the method and confirmed that the method was indeed called twice when switching from the second tab to the first one.

I cannot find a way to keep the user from scrolling between the views using horizontal gestures. I want to allow the user to tap the segmentedControl to change views, but I do not want the control to recognize and respond to horizontal gestures. I use several tableviews and I need the swipe to delete functionality; the tableview currently doesn't recognize swipe to delete since this gesture currently will only scroll between the views. I am using MXSegmentedPager only. Tried to remove the gesture recognizer delegate (among other things) and it did not work.

Hi,
my navigationBar is translucent and when I scroll down my tableview, the segmentedControl may disappear under the navigationBar

VGParallaxHeader implements updateParallaxHeaderViewHeight, which is not exposed here.

Hi @maxep, sorry for the massive number of issues I'm opening in those days :(

I'm having a rendering problem when using MXSegmentedPager without the parallax header and with an Translucent Navigation Bar.

You can reprocude the same bug using the MXSegmentedPager-Swift sample.

• Ad an Navigation Controller in the Main.storyboard
• Make the Navigation Controller as the Initial View Controller
• Connect the MXViewController as the root view controller of the Navigation Controller.
  0 In the Navigation Controller select the Navigation Bar component and enable Translucent from the Attributes inspector

Last step: comment out all parallaxHeader settings from the MXViewController.swift file and run.

The last two rows (Row 48 and Row 49) is partially hidden on the bottom of the view

Hi @maxep

Once again thanks for the awesome library...Is it possible to reuse the view controller..the way we reuse the uiview...my task is to create dynamic list of products under different categories which are dynamic..So i want to use a viewcontroller which has tableview in it and reuse that viewcontroller for multiple categories...

Thanks

When I implement segmentedpager at a detail page and want to push pop the view it crashes some times at first pop and sometimes at second push. Here is the call stack.

I tried to set the frame of segmentedControl but it does work.
self.segmentedPager.segmentedControl.frame = CGRectMake(10, 10, 300, 60);

HMSegmentedControl supports the use of NSAttributedString as titles, however the MXSegmentedPager control blocks this as the MXSegmentedPagerDatasource protocol prescribes the use of NSString (which NSAttributedString does not subclass from) as part of its interface contract on the datasource method:

- (NSString*) segmentedPager:(MXSegmentedPager*)segmentedPager titleForSectionAtIndex:(NSInteger)index;

Hi! @maxep
Thank you, open source is cool.

the selected item is highlighted.

not selected item is two color, blackColor at top and grayColor at bottom. look this picture

I'm wondering if it'd be easy to add the ability to lazily load a page. For example, rather than allocating all views for each tab on creation, I'd probably want to only load the current one in view or the current one and the next one so that I don't keep them all in memory. Essentially having something more like UIPageViewController where the pages are reused or allocated/deallocated when shown / hidden would be ideal.

Any thoughts on how this might be accomplished?

It doesn't look like all the latest code is in the latest podspec. Can you bump the version of the podspec so we can get the latest?

Hi, is there an easy way to use

- (UIView *)segmentedPager:(MXSegmentedPager *)segmentedPager viewForPageAtIndex:(NSInteger)index

to use View Controller Subviews that would be loaded only when the corresponding segment control is selected?

The goal would be to use view controllers' subviews where data is loaded.

I copied and pasted the code from MXParallaxViewController into a file (I called it SampleViewPager) in my project.

I then hooked it up to my REFrostedViewController (it is a drawer library I use which uses a panGestureRecognizer to slide the side menu in and out).

This causes it to crash at removeObserverFromView, specifically when it calls [view removeObserver: self forKeyPath:kContentOffsetKeyPath context:kMXScrollViewKVOContext];

It only crashes when the app loads and I try to scroll something within the tableview / webview / text view

Does MXSegmentedPager remove the navigation controller from displaying? I have a MXSegmentedPager embedded in a navigation controller (logging self.navgiationController outputs a NavigationController object) and it doesn't seem to show up (the nav bar).

Hello, I'm trying to resize my tableView width by updating the frame of tableview but doesn't worked , I've tried to update tableview with at creation time, at viewWillAppear, tied to change cell Size at cellForRow... but none of them worked any help over here ?

Hi, I'm using MXSegmentedPager inside an UINavigationController. In iOS 8 it works great but in iOS 9 there's a blank offset of 64 at the top, which I think is 20 from the status bar and 44 from the navigation bar. The parallax header wouldn't scroll above that blank space but the segmented controller would.

I was able to fix this bug by adding this lines at the top of your function in MXParallaxHeader.m file:

- (void) setScrollViewContentTopInset:(CGFloat)top {

   if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"9.0")) {
        top = self.height;
    }
   //rest of the code
}

Before update to v2.0 i used this method in MXSegmentedPager

• (void) scrollToPageAtIndex:(NSInteger)index animated:(BOOL)animated;

Thanks.

Based on the issue here: stoprocent/VGParallaxHeader#29 is there a chance you can update to using your fork of VGParallaxHeader so that updating the header height works correctly? If not, I'll have to fork MXSegmentedPager and use your fork of VGParallaxHeader in order to fix the issues I'm seeing.

I can't see any reference to a property supporting space between the page views within MXSegmentedPager and associated classes - apologies if I have missed it.

It would be nice to be able to support a 'gutter' between the page views like the UIPageView's UIPageViewControllerOptionInterPageSpacingKey option.

I want to display another view when the parallaxHeader has reached its minimum height. How do I catch the event of reaching the minimum height in MXSegmentedPager?

Hi @maxep, you can reproduce this bug by adding this code in the MXSegmentedPager-Swift sample:

override func numberOfPagesInSegmentedPager(segmentedPager: MXSegmentedPager) -> Int {
    return 0
}

Thanks,
Luca

When using parallax, if I create a UIViewController with a tableview inside as one of the pages, the tableview scrolls it's content when scrolling up (before hitting the top).

In the video below, the first page is a regular tableView which works correctly. The 'top' tab is a UIViewController with a tableView inside and displays how the tableView content is scrolling with the outer scrollView incorrectly.

Is there a way to insert a static (i.e. non parallax) view above the HMSegmentedControl - so the control does not appear at the top of the screen. For instance, if one wanted to put content above the control that shows regardless of selected segment.

Or is VGParallaxHeader the preferred approach to this - but 'turning off' the parallax effect?

Hi, when I dismissed the modal View Controller containing the MXSegmentPager instance, application crashed with the following error.

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'An instance 0x151e9000 of class MXScrollView was deallocated while key value observers were still registered with it. Current observation info: <NSKeyValueObservationInfo 0x16259d70> (...)'

You can set the parallax header and height. However, if you need to change the height of the header, there seems to be no way to do this.

Hi

I want to add a UIView with a button for navigation at the bottom of UIViewController extended from MXSegmentedPagerController. I kept it in xib but that's not working.

Hi @maxep
in this last two days I'm fighting with some memory leaks in my application, but I think this leaks depends by MXSegmentedPager.

So I've downloaded the MXSegmentedPager-Swift sample and I've added a new NavigationController with a button in the NavigationBar; this button will push your MXViewController.

• I've started the application with the Profile > Allocations inspector and before start I've checked the "Record reference counts" option; here the Inspector after launching the application (it's cleaned):

• I've clicked on the "Button" button; this button will push your MXViewController in the Navigation Controller:

• I've swipped between the tree tabs:

• A snapshot of the allocations when I come back to the Root View Controller:

• I'm again in the Root View Controller but this time I've opened and closed the MXViewController subview for 10 times.

Can you help me?

It's hard to say if this is my code implementation or something in MXSegmentedPager that needs to remove obserever. I'm getting the followed error when removing a view that has a MXSegmentedPager.

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'An instance 0x137577700 of class MXPagerView was deallocated while key value observers were still registered with it.

everytime its showing could not build objective-c module MXSegementedPager. Please solve this issue

I am a novice programmer and I would fix this on a fork if I could. But it seems like constraints to its superview are not being set within the control.

I did get the control working in Storyboard. But when I use it in the detail view controller for a UISplitViewController, then rotate the view from portrait to landscape, the width of the control does not resize. I set the constraints from the MXSegmentedPager to its superview, but within the MXSegmentedPager itself, it doesn't seem like there are constraints set for the various components.

Again, I would do it if I knew how. Just learning all of this.

Thanks again for this great control.

I'm trying to setup view pager. i returning 4 pages at number method , same title for every page and same tableview for every page.

P.S : I'm not using storyboards.
