我从另一个提出一个视图控制器:
- - (void)showModalView
- {
- UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
- MySecViewController *mySecViewController = [storyboard instantiateViewControllerWithIdentifier:@"secController"];
- mySecViewController.delegate = self;
- [self presentViewController:mySecViewController animated:YES completion:nil];
- }
然后在呈现的UIViewController中,方法viewWillTransitionToSize:withTransitionCoordinator:在iOS 8中调用但不在iOS 9中调用…
谢谢
解决方法
在您当前的视图控制器中,如果您覆盖了viewWillTransitionToSize:withTransitionCoordinator :,请确保您调用super.否则,此消息将不会传播到子视图控制器.
对于Objective-C:
- - (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator {
- [super viewWillTransitionToSize:size withTransitionCoordinator:coordinator];
- // Your other code ...
和斯威夫特:
- override func viewWillTransition(to size: CGSize,with coordinator: UIViewControllerTransitionCoordinator) {
- super.viewWillTransition(to: size,with: coordinator)
- // Your other code ...
- }
