Question

在Objective-C中，我想从右到左解除模态ViewController。

现在我可以在模态上从左向右移动。但我不知道如何从左到右解除这个模态VC，就像推屏过渡一样。

这是一个从a-ViewController移动到b-ViewController的代码。

bViewController *nextVC = [[bViewController alloc] initWithNibName:nil bundle:nil];

CATransition *transition = [CATransition animation];
transition.duration = 0.5; 
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
transition.type = kCATransitionPush ; 
[transition setSubtype:kCATransitionFromLeft];
[[nextVC.view layer] addAnimation:transition forKey:@"TransitionTest"]; 
//[self presentViewController:nextVC animated:YES completion:nil];
//if it's possible, I want to use upside's cord.(don't addSubView) but I don't know how to do it)
[self.view addSubview:nextVC.view] ;

Answer 1

Objective-C

CATransition *transition = [CATransition animation];
transition.duration = 0.4;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
[self.view.window.layer addAnimation:transition forKey:nil];
[self dismissViewControllerAnimated:NO completion:nil];

Swift 5

let transition = CATransition()
transition.duration = 0.5
transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
transition.type = CATransitionType.push
transition.subtype = CATransitionSubtype.fromRight
self.view.window!.layer.add(transition, forKey: nil)
self.dismiss(animated: false, completion: nil)

在Swift 4中，您可以使用Bellow代码。它正在为我工作。

        let transition = CATransition()
        transition.duration = 0.5
        transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
        transition.type = kCATransitionPush
        transition.subtype = kCATransitionFromRight 
        self.view.window!.layer.add(transition, forKey: nil)
        self.dismiss(animated: false, completion: nil)

<div ng-app="testApp">
  <div ng-controller="testCtrl as vm">
    <form ng-show="vm.showEditForm">
      <input type="text" />
      <input type="text" />
      <button ng-click="vm.update()">Submit</button>
    </form>
    <table>
      <tr>
        <th>Name</th>
        <th>Description</th>
      </tr>
      <tr ng-repeat="item in vm.list">
        <td>
          {{item.name}}
        </td>
        <td>
          {{item.desc}}
          <span ng-click="vm.toggleEditForm()">E</span>
          <span ng-click="vm.removeItem($index)">X</span>
        </td>
      </tr>
    </table>
  </div>
</div>

定义CATransition并实现上述实现。此代码可以使用dismiss使屏幕过渡到左侧和右侧。关键是要制作动画假。如果将动画设置为true，则原来的解散动作会混淆。

    transition.duration = 0.5
    transition.type = kCATransitionPush
    transition.subtype = kCATransitionFromLeft
    view.window!.layer.add(transition, forKey: kCATransition)
    dismiss(animated: false, completion: nil)

Answer 5

在Swift 3中

let transition = CATransition()
transition.duration = 0.5
transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.type = kCATransitionPush
transition.subtype = kCATransitionFromRight
view.layer.add(transition, forKey: "rightToLeftTransition")
dismiss(animated: true, completion: nil)
