iphone - UIView 动画 block UIView 交互

Question

我有一个名为 MainViewController 的 UIViewController。它的框架:我还有一个名为 SingleSearchView 的 UIView，它是 MainViewController 的 subview 。

然后我将这个 singleSearchView 添加到 MainViewController:

self.singleSearchView = [[SearchView alloc] initWithFrame:CGRectMake(0, -480, 320, 480)];
[self.view addSubview:singleSearchView];

当我尝试使用以下动画“切换”到 singleSearchView 时，它会阻止我与 singleSearchView 进行任何触摸交互/p>

[UIView beginAnimations:@"searchAnimation" context:nil];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:1.0f]; 
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:self.singleSearchView cache:YES];
[self.view setFrame:CGRectMake(0, 480, 320, 480)];    
[UIView commitAnimations];

我也试过这种方式:

[UIView animateWithDuration:1.5 delay:0 
                 options:UIViewAnimationOptionAllowUserInteraction 
                     animations:^{
                         [self.view setFrame:CGRectMake(0, 480, 320, 480)];  
                     }
                     completion:nil];

谢谢

从这里answer to another question :

Turns out UIView's block animation by default blocks user interaction, and to get around it you need to pass UIViewAnimationOptionAllowUserInteraction as one of the options. Hopefully someone else will have some use of this information as well.
