Android PagerTabStrip for iOS!

XLPagerTabStrip is a Container View Controller that allows us to switch easily among a collection of view controllers. Pan gesture can be used to move on to next or previous view controller. It shows a interactive indicator of the current, previous, next child view controllers.

XLPagerTabStrip was originally inspired by Tell market app.

Purpose

XLPagerTabStrip helps us deal with view controllers that have the same relevance for the user like Android PagerTabStrip and PageView do. Since you’re able to navigate between a large amount of view controllers, XLPagerTabStrip is an scalable and nice solution for this problem.

How to use it

Integrate XLPagerTabStrip is as easy as following these steps:

  1. Create a UIViewController class that should extend from either XLSegmentedPagerTabStripViewController, XLBarPagerTabStripViewController, XLButtonBarPagerTabStripViewController, XLTwitterPagerTabStripViewController.

  2. The recently created concrete view controller should conform to XLPagerTabStripViewControllerDataSource implementing: -(NSArray *)childViewControllersForPagerTabStripViewController:(XLPagerTabStripViewController *)pagerTabStripViewController;

  3. (Recomended) Set up your view controllers using a nib file or a Storyboard. We need to connect some IBOutlets (take a look at the Demo folder).

  4. Enjoy!

For further details take a look at the Demo folder to see the code of examples shown above.

FAQ

How to change the visible child view controller programmatically

XLPagerTabStripViewController provides the following methods to programmatically change the visible child view controller:

-(void)moveToViewControllerAtIndex:(NSUInteger)index;
-(void)moveToViewControllerAtIndex:(NSUInteger)index animated:(BOOL)animated;
-(void)moveToViewController:(UIViewController *)viewController;
-(void)moveToViewController:(UIViewController *)viewController animated:(BOOL)animated;
How to change the selected tab (XLButtonBarViewCell) look and feel based on the selected state

XLButtonBarPagerTabStripViewController provides a flexible way to customize the look and feel of a XLButtonBarViewCell based on the selected state by using blocks. These blocks will be called each time the current cell index changes its value.

@property (copy) void (^changeCurrentIndexProgressiveBlock)(XLButtonBarViewCell* oldCell, XLButtonBarViewCell *newCell, CGFloat progressPercentage, BOOL indexWasChanged, BOOL animated);
@property (copy) void (^changeCurrentIndexBlock)(XLButtonBarViewCell* oldCell, XLButtonBarViewCell *newCell, BOOL animated);

Since the collection cell (tab) is passed as a parameter you have full control on the look and fell change and animation.

Installation

The easiest way to use XLPagerTabStrip in your app is via CocoaPods.

  1. Add the following line in the project’s Podfile file:
    pod 'XLPagerTabStrip', '~> 2.0'.
  2. Run the command pod install from the Podfile folder directory.

Customization

The most interesting customizable features are:

  • Ability to skip intermediate view controllers when tapped on a "tab" (using skipIntermediateViewControllers property)
  • Indicators can be added at any position of the screen through storyboard layouts.
  • Choose between progressive, non-progressive indicators (using isProgressiveIndicator property)
  • Choose the alignment of the indicator as the user scrolls through tabs (using barButtonView.selectedBarAlignment property)
  • Add space padding between view controllers

Requirements

  • ARC
  • iOS 7.0 and above
