Android [PagerTabStrip](http://developer.android.com/reference/android/support/v4/view/PagerTabStrip.html) 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. |

|||
## Pager Types |
|||
|
|||
The library provides 4 different ways to show the view controllers. |
|||
|
|||
### Button Bar |
|||
|
|||
This is likely to be the most common pager type. It's used by many well known apps such as instagram, youtube, skype and many others. |
|||
|
|||
<img src="Example/barButton.gif" width="250"/> |
|||
|
|||
### Bar |
|||
|
|||
This mode doesn't show a title neither an image. It only shows a bar that indicates the current view controller. |
|||
|
|||
<img src="Example/bar.gif" width="250"/> |
|||
|
|||
### Twitter |
|||
|
|||
Long time ago twitter app made use of this type of pager in the app main screen. |
|||
|
|||
<img src="Example/twitter.gif" width="250"/> |
|||
|
|||
### Segmented |
|||
|
|||
This mode uses a `UISegmentedControl` to indicates which is the view controller being displayed. |
|||
|
|||
<img src="Example/segmented.gif" width="250"/> |
|||
|
|||
## Usage |
|||
|
|||
Basically we just need to provide the list of child view controllers to show and these view controllers should provide the information (title or image) that will be shown in the associated indicator. |
|||
|
|||
Let's see the steps to do this: |
|||
|
|||
##### Choose which type of pager we want to create |
|||
|
|||
First we should choose the type of pager we want to create, depending on our choice we will have to create a view controller that extends from one of the following controllers: `TwitterPagerTabStripViewController`, `ButtonBarPagerTabStripViewController`, `SegmentedPagerTabStripViewController`, `BarPagerTabStripViewController`. |
|||
|
|||
> All these build-in pager controllers extend from the base class `PagerTabStripViewController`. |
|||
> You can also make your custom pager controller by extending directly from `PagerTabStripViewController` in case no pager menu type fits your needs. |
|||
|
|||
```swift |
|||
import XLPagerTabStrip |
|||
|
|||
class MyPagerTabStripName: ButtonBarPagerTabStripViewController { |
|||
.. |
|||
} |
|||
``` |
|||
|
|||
##### Connect outlets and add layout constraints |
|||
|
|||
We strongly recommend to use IB to set up our page controller views. |
|||
|
|||
Drag into the storyboard a `UIViewController` and set up its class with your pager controller (`MyPagerTabStripName`). |
|||
Drag a `UIScrollView` into your view controller view and connect `PagerTabStripViewController` `containerView` outlet with the scroll view. |
|||
|
|||
Depending on which type of paging view controller you are working with you may have to connect more outlets. |
|||
|
|||
For `BarPagerTabStripViewController` we should connect `barView` outlet. barView type is UIView. `ButtonBarPagerTabStripViewController` requires us to connect `buttonBarView` outlet. `buttonBarView` type is `ButtonBarView` which extends from `UICollectionView`. `SegmentedPagerTabStripViewController` has a `segmentedControl` outlet, if the outlet is not connected the library try to set up the navigationItem `titleView` property using a `UISegmentedControl`. `TwitterPagerTabStripViewController` doesn't require us to connect any additional outlet. |
|||
|
|||
> The example project contains a example for each pager controller type and we can look into it to see how views were added and how outlets were connected. |
|||
|
|||
##### Provide the view controllers that will appear embedded into the PagerTabStrip view controller |
|||
|
|||
You can provide the view controllers by overriding `func viewControllers(for: pagerTabStripController: PagerTabStripViewController) -> [UIViewController]` method. |
|||
|
|||
```swift |
|||
override public func viewControllers(for pagerTabStripController: PagerTabStripViewController) -> [UIViewController] { |
|||
return [MyEmbeddedViewController(), MySecondEmbeddedViewController()] |
|||
} |
|||
``` |
|||
|
|||
> The method above is the only method declared in `PagerTabStripDataSource` protocol. We don't need to explicitly conform to it since base pager class already does it. |
|||
|
|||
|
|||
##### Provide information to show in each indicator |
|||
|
|||
Every UIViewController that will appear within the PagerTabStrip needs to provide either a title or an image. |
|||
In order to do so they should conform to `IndicatorInfoProvider` by implementing `func indicatorInfo(for pagerTabStripController: PagerTabStripViewController) -> IndicatorInfo` |
|||
which provides the information required to show the PagerTabStrip menu (indicator) associated with the view controller. |
|||
|
|||
```swift |
|||
class MyEmbeddedViewController: UITableViewController, IndicatorInfoProvider { |
|||
|
|||
func indicatorInfo(for pagerTabStripController: PagerTabStripViewController) -> IndicatorInfo { |
|||
return IndicatorInfo(title: "My Child title") |
|||
} |
|||
} |
|||
``` |
|||
|
|||

|||
|
|||
That's it! We're done! 🍻🍻 |
|||
|
|||
|
|||
## Customization |
|||
|
|||
##### Pager Behaviour |
|||
|
|||
The pager indicator can be updated progressive as we swipe or at once in the middle of the transition between the view controllers. |
|||
By setting up `pagerBehaviour` property we can choose how the indicator should be updated. |
|||
|
|||
```swift |
|||
public var pagerBehaviour: PagerTabStripBehaviour |
|||
``` |
|||
|
|||
```swift |
|||
public enum PagerTabStripBehaviour { |
|||
case Common(skipIntermediteViewControllers: Bool) |
|||
case Progressive(skipIntermediteViewControllers: Bool, elasticIndicatorLimit: Bool) |
|||
} |
|||
``` |
|||
|
|||
Default Values: |
|||
```swift |
|||
// Twitter Type |
|||
PagerTabStripBehaviour.Common(skipIntermediteViewControllers: true) |
|||
// Segmented Type |
|||
PagerTabStripBehaviour.Common(skipIntermediteViewControllers: true) |
|||
// Bar Type |
|||
PagerTabStripBehaviour.Progressive(skipIntermediteViewControllers: true, elasticIndicatorLimit: true) |
|||
// ButtonBar Type |
|||
PagerTabStripBehaviour.Progressive(skipIntermediteViewControllers: true, elasticIndicatorLimit: true)` |
|||
``` |
|||
|
|||
As you might have noticed `Common` and `Progressive` enumeration cases has `skipIntermediteViewControllers` and `elasticIndicatorLimit` associated values. |
|||
|
|||
`skipIntermediteViewControllers` allows us to skip intermediate view controllers when a tab indicator is tapped. |
|||
|
|||
`elasticIndicatorLimit` allows us to tension the indicator when we reach a limit, I mean when we try to move forward from last indicator or move back from first indicator. |
|||
|
|||
##### PagerTabStripDelegate & PagerTabStripIsProgressiveDelegate |
|||
|
|||
Normally we don't need to implement these protocols because each pager type already conforms to it in order to properly update its indicator. Anyway there may be some scenarios when overriding a method come come in handy. |
|||
|
|||
```swift |
|||
public protocol PagerTabStripDelegate: class { |
|||
|
|||
func updateIndicator(for viewController: PagerTabStripViewController, fromIndex: Int, toIndex: Int) |
|||
} |
|||
|
|||
public protocol PagerTabStripIsProgressiveDelegate : PagerTabStripDelegate { |
|||
|
|||
func updateIndicator(for viewController: PagerTabStripViewController, fromIndex: Int, toIndex: Int, withProgressPercentage progressPercentage: CGFloat, indexWasChanged: Bool) |
|||
} |
|||
``` |
|||
|
|||
> Again, The method invoked by the library depends on the `pagerBehaviour` value. |
|||
|
|||
|
|||
|
|||
|
|||
### ButtonBar Customization |
|||
|
|||
```swift |
|||
|
|||
settings.style.buttonBarBackgroundColor: UIColor? |
|||
// buttonBar minimumInteritemSpacing value, note that button bar extends from UICollectionView |
|||
settings.style.buttonBarMinimumInteritemSpacing: CGFloat? |
|||
// buttonBar minimumLineSpacing value |
|||
settings.style.buttonBarMinimumLineSpacing: CGFloat? |
|||
// buttonBar flow layout left content inset value |
|||
settings.style.buttonBarLeftContentInset: CGFloat? |
|||
// buttonBar flow layout right content inset value |
|||
settings.style.buttonBarRightContentInset: CGFloat? |
|||
|
|||
// selected bar view is created programmatically so it's important to set up the following 2 properties properly |
|||
settings.style.selectedBarBackgroundColor = UIColor.blackColor() |
|||
settings.style.selectedBarHeight: CGFloat = 5 |
|||
|
|||
// each buttonBar item is a UICollectionView cell of type ButtonBarViewCell |
|||
settings.style.buttonBarItemBackgroundColor: UIColor? |
|||
settings.style.buttonBarItemFont = UIFont.systemFontOfSize(18) |
|||
// helps to determine the cell width, it represent the space before and after the title label |
|||
settings.style.buttonBarItemLeftRightMargin: CGFloat = 8 |
|||
settings.style.buttonBarItemTitleColor: UIColor? |
|||
// in case the barView items do not fill the screen width this property stretch the cells to fill the screen |
|||
settings.style.buttonBarItemsShouldFillAvailiableWidth = true |
|||
// only used if button bar is created programmatically and not using storyboards or nib files as recommended. |
|||
public var buttonBarHeight: CGFloat? |
|||
``` |
|||
|
|||
**Important:** Settings should be called before `viewDidLoad` is called. |
|||
```swift |
|||
override func viewDidLoad() { |
|||
self.settings.style.selectedBarHeight = 2 |
|||
self.settings.style.selectedBarBackgroundColor = UIColor.whiteColor() |
|||
|
|||
super.viewDidLoad() |
|||
} |
|||
``` |
|||
|
|||
##### Update cells when selected indicator changes |
|||
|
|||
We may need to update the indicator cell when the displayed view controller changes. The following function properties help to accomplish that. Depending on our pager `pagerBehaviour` value we will have to set up `changeCurrentIndex` or `changeCurrentIndexProgressive`. |
|||
|
|||
```swift |
|||
public var changeCurrentIndex: ((oldCell: ButtonBarViewCell?, newCell: ButtonBarViewCell?, animated: Bool) -> Void)? |
|||
public var changeCurrentIndexProgressive: ((oldCell: ButtonBarViewCell?, newCell: ButtonBarViewCell?, progressPercentage: CGFloat, changeCurrentIndex: Bool, animated: Bool) -> Void)? |
|||
``` |
|||
|
|||
Let's see an example: |
|||
|
|||
```swift |
|||
changeCurrentIndexProgressive = { (oldCell: ButtonBarViewCell?, newCell: ButtonBarViewCell?, progressPercentage: CGFloat, changeCurrentIndex: Bool, animated: Bool) -> Void in |
|||
guard changeCurrentIndex == true else { return } |
|||
|
|||
oldCell?.label.textColor = UIColor(white: 1, alpha: 0.6) |
|||
newCell?.label.textColor = .whiteColor() |
|||
|
|||
if animated { |
|||
UIView.animateWithDuration(0.1, animations: { () -> Void in |
|||
newCell?.transform = CGAffineTransformMakeScale(1.0, 1.0) |
|||
oldCell?.transform = CGAffineTransformMakeScale(0.8, 0.8) |
|||
}) |
|||
} |
|||
else { |
|||
newCell?.transform = CGAffineTransformMakeScale(1.0, 1.0) |
|||
oldCell?.transform = CGAffineTransformMakeScale(0.8, 0.8) |
|||
} |
|||
} |
|||
``` |
|||
|
|||
### Bar Type Customization |
|||
|
|||
```swift |
|||
settings.style.barBackgroundColor: UIColor? |
|||
settings.style.selectedBarBackgroundColor: UIColor? |
|||
// barHeight is only set up when the bar is created programmatically and not using storyboards or xib files as recommended. |
|||
settings.style.barHeight: CGFloat = 5 |
