Hey there,
I couldn't get this to work with Swift, even with a bridging header. Keeps saying the classes aren't found. Has anyone gotten this to work in a Swift project?

Thanks

Hi !

What about setting the currentIndex property to public in order to know which tab controller is actually displayed ? :)

BTW, thx for your work !

Best,

Add possibility to show tabs at bottom of the screen

Hello,

I am using this cocoa pod and able to use it properly. However, I want to disable tab bar indicator. I know how to disable tab bar indicator if I inherit directly from Scroll View since it has necessary methods, but I inherit from GUITabPagerViewController in my view controller and there isn't any method associated with that. Thus, I came up with an idea of inheriting from GUITabPagerViewController and GUITabScrollView both, however Objective C does not allow multiple inheritance.

Is there an idea how I can achieve this?

Please provide access to the tab color not only to the line under the tab.

I am adding TableView in each Tab , so when i scroll up and Down on UITableView the Tab changes from one Tab to another .

Please help me out ?
Thanks in advance !

my code create view

• (UIView *)viewForTabAtIndex:(NSInteger)index {
  UIView *view=[[UIView alloc]init];
  //view.backgroundColor=[UIColor orangeColor];
  UIImageView *img=[UIImageView new];
  view.frame=CGRectMake(10, 13, 60, self.tabHeight);

  img.frame=CGRectMake(20, 15, 22, 22);
  img.image=[UIImage imageNamed:[self.images objectAtIndex:index]];
  [view addSubview:img];
  return view;
  }

i want to change images when i select tab..is there method for that?

Hi , please check this, i run the demo on ios7 , is this a bug?

Sometimes if you swipe quickly between the tabs the tab index shows to the wrong tab

Can you please provide a Swift 3 version for this library?

Hey,

There's an issue with the constraints as far as I can tell. Here's the error message:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Unable to parse constraint format: Expected a view H:|-165.000000-|

Any help would be awesome! Thanks :D

Wrong header tab indicator line frame when -numberOfViewControllers return a small number

Hi,
I have a collectoin view and when i click on one item i need to open another view controller with GUITabPagerViewController and show corresponding tab. At this moment always it opens first tab.

Is there any solution for this?

I need to disable/enable the ability to change the tab when a action is called in the pageview. I have no idea how i could access the pageviewcontroller before the swipe gestures is called.

I tried it with additional delegate methods in the guitabpagerviewcontroller and i also tried to access directly from my main controller to set pageViewControllerObject.view.userInteractionEnabled = NO; It is not possible because the pageviewcontroller is a child of UIPageViewControllerContentView.
So i become a warning: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[_UIPageViewControllerContentView childViewControllers]: unrecognized selector sent to instance.

Hi,
if you run this project on XCode7 you get this crash:

Changing

NSLayoutAttributeLeading to NSLayoutAttributeLeft seems works...

Hi ,
Firstly i would like to thank you for providing this SDK . It is very userfriendly . But i would like to know how to give the equal spacing between three tabs. I have a scenario where i have three tabs (like Tab 1 , Tab2 , Tab 3). Actually in your SDK tabs are starting from Middle . Could you say me the appropriate method to give equal spacing . It would be helpful in my project .

Thank you ,
Waiting for your reply

I only have 2 tabs, but they are the center position, how can I set them start from left ?

[NSLayoutConstraint constraintWithItem:attribute:relatedBy:toItem:attribute:multiplier:constant:]: A constraint cannot be made between a leading/trailing attribute and a right/left attribute. Use leading/trailing for both or neither.

1. If I have three tabs, and run the application on the iPhone 6 or iPhone 6+, the tabs are on the left side, not in the center. Or stretch the tabs on the width of the screen. So it will be more beautiful ;)
   
2. When I ViewController is tied to his NavigationController, the tabs are raised up and hide behind NavigationBar.
   
   thank you ;)

The base class GUITabPagerViewController UIViewController does not forwards UIViewController display events:

-(void)viewDidAppear:(BOOL)animated;
-(void)viewDidDisappear:(BOOL)animated;

etc.

I want to set all tabs left alignment initially.

can you help me ??

It can be reproduced when you rotate on ipad. iOS 8 has worse situation than iOS 9 and 10.

Hi, How to set the text color when selected?

Perhaps it was caused by this sentence in GUITabScrollView.m :
[contentView setTranslatesAutoresizingMaskIntoConstraints:NO].
it fixed after i delete it.

And the header view doesn't show well when rotation changed.

sorry for my poor english

I want to have different font for each tab title. How can this be done?

please make idea. 💃
