Blog for this: [Part I](http://www.jianshu.com/p/7a35ee30e90c), [Part II](http://www.jianshu.com/p/2cdf0729934f) 3 | 4 | ![AlbumTransition](https://github.com/seedante/SDECollectionViewAlbumTransition/blob/PinchPopTransition/Figures/AlbumTransition.gif) 5 | 6 | 7 | ## Installtion 添加到你的工程 8 | 9 | Drag files in "Classes" folder into your project. 10 | 11 | 将 Classes 里的文件拖到你的工程中即可。 12 | 13 | ## Usage 使用方法 14 | 15 | - In your storyboard, drag a Object to your navigation controller, and set its custom class to "SDENavigationControllerDelegate" 16 | - 在你的 storyboard 里，拖一个 Object 到你的 navigation controller 上面，并将这个 Object 的类设置为「SDENavigationControllerDelegate」。 17 | 18 | ![drag an Object and set the custom class](https://github.com/seedante/SDECollectionViewAlbumTransition/blob/PinchPopTransition/Figures/Config1.png) 19 | 20 | - Set this object to be your navigation controller's delegate. 21 | - 将这个 Object 设置为 navigation controller 的 delegate。 22 | 23 | ![set the delegate](https://github.com/seedante/SDECollectionViewAlbumTransition/blob/PinchPopTransition/Figures/Config2.png) 24 | 25 | 26 | - At the last, add the follow codes in your UICollectionView's delegate: 27 | - 最后要做的一件事是，在下面的方法中添加几行行代码： 28 | 29 | override func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) { 30 | self.selectedIndexPath = indexPath 31 | self.collectionView?.allowsSelection = false //disable interaction to prevent the issue of double tap on cell 32 | ... 33 | self.navigationController?.pushViewController(toVC, animated: true) 34 | self.collectionView?.allowsSelection = true //enable again after push. 35 | } 36 | 37 | **Now the collectionView supports to pinch to pop.** 38 | 39 | **现在当前的这个 collectionView 已经支持使用 pinch 手势来执行 pop 了。** 40 | 41 | 42 | ## Requirements 使用条件 43 | 44 | - iOS 8.0+ 45 | - Swift 2.0 46 | 47 | Thanks for [@CezaryKopacz](https://github.com/CezaryKopacz/CKWaveCollectionViewTransition), [@ColinEberhardt](https://github.com/ColinEberhardt/VCTransitionsLibrary). I learn a lot from their repo. 48 | And thanks for [ Vincent Ngo](http://www.raywenderlich.com/94565/how-to-create-an-ios-book-open-animation-part-1) very much, I find the key to resolve the problem of pinching to push. 49 | There is a little problem with time delta algorithm, I will update if I find the way to improvement. 50 | 51 | ## Pinch to push? 使用 Pinch 手势支持 push？ 52 | 53 | Pinching to push is a little complex. ViewController to push must be created before push, and init a ViewController is complex than do something to a existed ViewController, so this is why most of libraries do not support pinch to push. 54 | 55 | 使用 pinch 手势来支持 push 操作有点麻烦。在 push 一个视图控制器前必然要生成一个实例，但这个类别是未知的，需要你来决定，这就是为什么很多库只支持 pinch push 的原因，pop 前视图控制器已经存在了，就不存在这个困扰。 56 | 57 | If you want to use pinch to support push and pop both, switch to the branch "Pinch-Push-Pop-Transition", drag files in "Classes" folder in this branch into your project, 58 | there is a little difference between "Pinch-Push-Pop-Transition" branch with other branches. 59 | 60 | 如果你想使用 pinch 手势同时支持 push 和 pop 操作，那么当前的分支的模式就不能用了，请切换到「Pinch-Push-Pop-Transition」分支。同样地，将 Classes 文件夹里的文件拖到你的工程里。 61 | 62 | Add the below properties to your UICollectionViewController child class: 63 | 64 | 在你的 UICollectionViewController 子类添加以下属性和方法： 65 | 66 | var transitionDelegate: SDENavigationControllerDelegate? 67 | var pinchGestureRecognizer: UIPinchGestureRecognizer?{ 68 | didSet(newValue){ 69 | collectionView?.addGestureRecognizer(pinchGestureRecognizer!) 70 | } 71 | } 72 | 73 | override viewDidLoad(){ 74 | ... 75 | pinchGestureRecognizer = UIPinchGestureRecognizer(target: self, action: "handlePinch:") 76 | } 77 | 78 | deinit{ 79 | if pinchGestureRecognizer != nil{ 80 | collectionView?.removeGestureRecognizer(pinchGestureRecognizer!) 81 | } 82 | } 83 | 84 | //MARK: Pinch Push and Pop 85 | func getIndexPathForGesture(gesture: UIPinchGestureRecognizer) -> NSIndexPath?{ 86 | let location0 = gesture.locationOfTouch(0, inView: gesture.view) 87 | let location1 = gesture.locationOfTouch(1, inView: gesture.view) 88 | let middleLocation = CGPointMake((location0.x + location1.x)/2, (location0.y + location1.y)/2) 89 | let indexPath = collectionView?.indexPathForItemAtPoint(middleLocation) 90 | return indexPath 91 | } 92 | 93 | func handlePinch(gesture: UIPinchGestureRecognizer){ 94 | switch gesture.state{ 95 | case .Began: 96 | if gesture.scale >= 1.0{ 97 | guard let indexPath = getIndexPathForGesture(gesture) else{ 98 | return 99 | } 100 | 101 | self.selectedIndexPath = indexPath 102 | 103 | if let toVC = ...{ 104 | transitionDelegate = navigationController?.delegate as? SDENavigationControllerDelegate 105 | transitionDelegate?.interactive = true 106 | navigationController?.pushViewController(toVC, animated: true) 107 | } 108 | 109 | }else{ 110 | //after view controller is poped, UIViewController.navigationController is nil. So you need to keep it somewhere before pop 111 | transitionDelegate = self.navigationController?.delegate as?
