ios - 自定义转场崩溃

Question

我创建了一个自定义转场:

-(void)perform{

UIViewController *destination = [self destinationViewController];
UIViewController *source = [self sourceViewController];

[source.view addSubview:destination.view];

CGRect destionationFrame = destination.view.frame;
CGRect sourceFrame = source.view.frame;
CGSize sourceSize = CGSizeMake(sourceFrame.size.height, sourceFrame.size.width);

destination.view.frame = CGRectMake(sourceSize.width,0,destionationFrame.size.width,destionationFrame.size.height);

[UIView animateWithDuration:0.3
                      delay:0
                    options:UIViewAnimationCurveEaseInOut | UIViewAnimationOptionBeginFromCurrentState
                 animations:^{
                     destination.view.frame = CGRectMake(sourceSize.width-destionationFrame.size.width,0,destionationFrame.size.width,destionationFrame.size.height);
                 } completion:^(BOOL finished) {
                     //[source presentModalViewController:destination animated:NO completion:nil];
                     //[source presentModalViewController:destination animated:NO];
                 }];

}

问题是，如果我在动画完成时不执行任何操作，触摸目标 Controller 的任何控件都会导致应用程序崩溃。

如果我制作一个presentModalViewController，则会导致屏幕上的任何对象做出响应。

有什么帮助吗？谢谢

既然你这样做了:

[source.view addSubview:destination.view];

您首先需要执行以下操作:

[源addChildViewController:目标];

但不确定它是否能解决您的问题。
