如何实现自定义segue动画？

Question

我分类为UIStoryboardSegue以执行自定义节奏动画。为了使动画可见，我必须添加目标为ViewController的视图作为临时视图。执行动画后，我将删除临时视图并通过（presentViewController：animated：NO）呈现最终的ViewController。

然而这会导致以下警告：“不平衡呼叫开始/结束外观转换为”。

如果我保留我的临时视图并且不删除它，警告不会出现，但最终视图不再响应触摸事件。如何摆脱这个警告？

我的自定义代码赛格瑞：

-(void)perform { 

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

    destinationViewController.view.alpha = 0.; 
    destinationViewController.view.transform = CGAffineTransformScale(destinationViewController.view.transform, 4.0, 4.0); 

    [sourceViewController.view addSubview:destinationViewController.view]; 

    [UIView animateWithDuration:kSSSpriteKitFadeOutDuration 
          delay:0.0 
         options:UIViewAnimationOptionCurveEaseInOut 
        animations:^{ 

         destinationViewController.view.transform = CGAffineTransformScale(destinationViewController.view.transform, 0.25, 0.25); 
         destinationViewController.view.alpha = 1.; 
        } 
        completion:^(BOOL finished){ 
         [destinationViewController.view removeFromSuperview]; // remove from temp super view 
         [sourceViewController presentViewController:destinationViewController animated:NO completion:NULL]; // present VC 
        }]; 
}

我拿着4 UIStoryboardSegue类型的类。 2为动画开始，2为动画停止。所以我打算分享4个班级的所有代码。请尝试解决这个问题。

CustomSegue.h

#import <UIKit/UIKit.h> 
@interface CustomSegue : UIStoryboardSegue 

// Originating point for animation 
@property CGPoint originatingPoint; 
@property CGRect Startingframe; 
@end 

CustomSegue.m

#import "CustomSegue.h" 
@implementation CustomSegue 

- (void)perform 
{ 
    UIViewController *sourceViewController = self.sourceViewController; 
    UIViewController *destinationViewController = self.destinationViewController; 

    // Add the destination view as a subview, temporarily 
    [sourceViewController.view addSubview:destinationViewController.view]; 

    // Transformation start scale 
    float width = 320; 
    float height = 480; 

    float x_Scale = self.Startingframe.size.width/width; 
    float Y_Scale = self.Startingframe.size.height/height; 

    destinationViewController.view.transform = CGAffineTransformMakeScale(x_Scale, Y_Scale); 

    // Store original centre point of the destination view 
    CGPoint originalCenter = destinationViewController.view.center; 
    // Set center to start point of the button 
    destinationViewController.view.center = self.originatingPoint; 

    [UIView animateWithDuration:0.5 
         delay:0.0 
        options:UIViewAnimationOptionCurveEaseInOut 
       animations:^ 
       { 
        // Grow! 
         destinationViewController.view.transform = CGAffineTransformMakeScale(1.0, 1.0); 

        destinationViewController.view.center = originalCenter; 
       } 
       completion:^(BOOL finished) 
       { 
        [destinationViewController.view removeFromSuperview]; // remove from temp super view 
        [sourceViewController presentViewController:destinationViewController animated:NO completion:NULL]; // present VC 
       }]; 
} 

@end 

CustomUnwindSegue.h

CustomUnwindSegue.m

#import "CustomUnwindSegue.h" 

@implementation CustomUnwindSegue 

- (void)perform { 
    UIViewController *sourceViewController = self.sourceViewController; 
    UIViewController *destinationViewController = self.destinationViewController; 

    // Transformation End scale 
    float width = 320; 
    float height = 480; 

    float x_Scale = self.endFrame.size.width/width; 
    float Y_Scale = self.endFrame.size.height/height; 
    // Add view to super view temporarily 
    [sourceViewController.view.superview insertSubview:destinationViewController.view atIndex:0]; 

    [UIView animateWithDuration:0.5 
         delay:0.0 
        options:UIViewAnimationOptionCurveEaseInOut 
       animations:^{ 
        // Shrink! 
        sourceViewController.view.transform = CGAffineTransformMakeScale(x_Scale, Y_Scale); 
        sourceViewController.view.center = self.targetPoint; 
       } 
       completion:^(BOOL finished){ 
        [destinationViewController.view removeFromSuperview]; // remove from temp super view 
        [sourceViewController dismissViewControllerAnimated:NO completion:NULL]; // dismiss VC 
       }]; 
} 

@end 

只要连接与此自定义动画赛格瑞你的行动象下面这样：因为它只是一个不同的过渡动画
