如何从右到左关闭模态ViewController？

Question

在Objective-C中,我想从右到左忽略模态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雇这个模态VC,就像推屏转换一样.

这是从aViewController移动到bViewController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

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];

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)
