如何识别敲击整个振荡子视图来执行交互动画

Question

在下面的代码中，子视图(云)在给定的位置上振荡。在振荡时点击子视图，它会移出边界到右侧，然后从左侧移进来。但是轻拍手势不是在整个子视图上工作，它只在振荡子视图的右端工作。我希望在cloud的整个子视图被点击时，滑动出和滑动入都能工作

下面分别是。h和。m文件的代码。

文件:OscillatingCloudsViewController.h

#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>
@interface OscillatingCloudsViewController : UIViewController
{
    IBOutlet UIView *movingCloud1;
    UIImage *cldImg;
}
- (IBAction)animateCloud;
- (IBAction)animateCloudBegin;
@end

    tapGesture.numberOfTapsRequired = 1;
    tapGesture.numberOfTouchesRequired = 1;
    tapGesture.cancelsTouchesInView = YES;
    [movingCloud1 addGestureRecognizer:tapGesture];
    movingCloud1.userInteractionEnabled = YES;
    [super viewWillAppear:
     animated];

    [movingCloud1 setBackgroundColor:[UIColor colorWithPatternImage:cldImg]];
    [self.view addSubview:movingCloud1];
    movingCloud1.userInteractionEnabled = YES;
    [self viewWillAppear:YES];
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:5];

    CGPoint pos = movingCloud1.center;
    pos.x = 220.0f;
    movingCloud1.center = pos;
    [UIView commitAnimations];
}
- (void) animateCloudHidden

我理解你的问题了。在viewwillApper中，你正在传递手势，并在内部animateCloud方法中分配你的movingCloud1 UIView。

要实现这一点，您需要遵循bello步骤。

• 在ViewdidLoad你需要分配和添加movingCloud1视图到你的self.view

• 添加手势到movingCloud1视图后

• 你的tapGesture现在可以工作了。所以在tapgesture方法中你只需要为movingCloud1视图设置动画
