iOS 7.1 UIModalPresentationCustom警告消息

Question

自从我转到 iOS 7.1 后，我不断收到每个自定义转换的警告消息。如何摆脱这个：

  

“UIModalPresentationCustom演示文稿样式只能用于   动画师或无人解雇。“

Answer 1

我有同样的问题。我不得不在呈现控制器中保留转换代表，因为当我从提交的控制器中解雇时它是零。

@property (strong, nonatomic) YourTransitioningDelegate *transitioningDelegate;

@synthesize transitioningDelegate;

transitioningDelegate = [[YourTransitioningDelegate alloc] init];

UIViewController *presentingController = [[UIViewController alloc] init];
presentingController.transitioningDelegate = transitioningDelegate;
[self presentViewController:presentingController];

Answer 2

我有同样的警告，但我所做的是从 UIViewControllerTransitioningDelegate 协议实现animationControllerForDismissedController。

- (id<UIViewControllerAnimatedTransitioning>)animationControllerForDismissedController;
