Animation 自定义Segue不允许目标控制器中的iActions

我有两个带有视图的视图控制器。第一个屏幕是登录屏幕，第二个屏幕从web获取内容（不相关）

我使用了一个自定义的segue动画，不得不对superview做一些奇怪的事情，以使sourceViewController.view在destinationViewController.view的“顶部”（视觉上）

我只能假设这就是为什么当我试图从第二个视图调用iAction方法时，它们不会调用

以下是segue类的实现：

- (void) perform {

    UIViewController *sourceViewController = (UIViewController *) self.sourceViewController;
    UIViewController *destinationViewController = (UIViewController *) self.destinationViewController;

    UIView *parent = sourceViewController.view.superview;
    [sourceViewController.view removeFromSuperview];
    [parent addSubview: destinationViewController.view];
    [parent addSubview:sourceViewController.view];
    sourceViewController.view.layer.masksToBounds = NO;
    sourceViewController.view.layer.cornerRadius = 8; // if you like rounded corners
    sourceViewController.view.layer.shadowOffset = CGSizeMake(0,0);
    sourceViewController.view.layer.shadowRadius = 10;
    sourceViewController.view.layer.shadowOpacity = 1;

    destinationViewController.view.frame = CGRectMake(0, 20, destinationViewController.view.frame.size.width, destinationViewController.view.frame.size.height);
    sourceViewController.view.frame = CGRectMake(0, 20, sourceViewController.view.frame.size.width, sourceViewController.view.frame.size.height);

    [UIView animateWithDuration:.6
                          delay:0.0
                        options:UIViewAnimationCurveEaseInOut
                     animations:^{

                         sourceViewController.view.frame = CGRectMake(-sourceViewController.view.frame.size.width-10, 20, sourceViewController.view.frame.size.width, sourceViewController.view.frame.size.height);
                     }
                     completion:^(BOOL finished){
                         //[destinationViewController.view removeFromSuperview];
                         [sourceViewController.navigationController pushViewController:destinationViewController animated:NO];
                     }];
}

我的问题是，将源代码视图从它的超级视图中移除，然后玩弄它会破坏第二个视图中调用iActions的方式吗

iAction方法只是在按下按钮时使应用程序崩溃。

我通过将代码更改为以下内容解决了问题：

UIViewController *sourceViewController = (UIViewController *) self.sourceViewController;
    UIViewController *destinationViewController = (UIViewController *) self.destinationViewController;
UIView *parent = sourceViewController.view.superview;
[parent addSubview:destinationViewController.view];
[parent sendSubviewToBack: destinationViewController.view];
    sourceViewController.view.layer.masksToBounds = NO;
    sourceViewController.view.layer.cornerRadius = 8; // if you like rounded corners
    sourceViewController.view.layer.shadowOffset = CGSizeMake(0,0);
    sourceViewController.view.layer.shadowRadius = 10;
    sourceViewController.view.layer.shadowOpacity = 1;
destinationViewController.view.frame = CGRectMake(0, 20, destinationViewController.view.frame.size.width, destinationViewController.view.frame.size.height);
    sourceViewController.view.frame = CGRectMake(0, 20, sourceViewController.view.frame.size.width, sourceViewController.view.frame.size.height);

    [UIView animateWithDuration:.6
                          delay:0.0
                        options:UIViewAnimationCurveEaseInOut
                     animations:^{

                         sourceViewController.view.frame = CGRectMake(-sourceViewController.view.frame.size.width-10, 20, sourceViewController.view.frame.size.width, sourceViewController.view.frame.size.height);
                     }
                     completion:^(BOOL finished){
                         [sourceViewController presentViewController:destinationViewController animated:NO completion:NULL];
                     }];

有些事情改变了，但值得注意的是，我

[sourceViewController presentViewController:destinationViewController animated:NO completion:NULL];

正确初始化控制器。 希望这能在将来帮助其他人
