当我点击图像时，它在 iphone 5s 上无法正常工作

Question

I added an image to a button. I am using gestures for animating the image in my sample app. It was working fine with iPhone 4, 4s, and 5 but the problem arise from iphone 5s.

` -(void)awakeFromNib
 {
  [super awakeFromNib];

   UITapGestureRecognizer *tapGestureRecognizer =                  [[UITapGestureRecognizer alloc] initWithTarget:self     action:@selector(characterImagedTapped)];

 self.characterImageView.userInteractionEnabled = YES;
 [self.characterImageView addGestureRecognizer:tapGestureRecognizer];

}

这里是characterImagedTapped函数，

' -(void) characterImagedTapped { if ([self.delegate respondsToSelector:@selector(didCharacterTapped:)]) [self.delegate performSelector:@selector(didCharacterTapped:)]; } ' 这个函数正在调用 didCharacterTapped。

When I tapped on the button it will call didCharacterTapped function it's implementation as below:
-(void)didCharacterTapped:(BOOL)tapped    
{
    if (tapped && !isCharacterAnimating) {
        [self startWelcomeBackCharacterAnimation];
    }
}`

如果点击值为 YES，它将调用 startWelcomeBackCharacterAnimation。如果为 NO，它将跳过并且图像不会被动画化。

实际上，当我点击按钮时，点击的布尔值应该是 YES，但从 iPhone 5s 版本开始，点击的布尔值总是显示 NO。

Answer 1

-(void) characterImagedTapped
{
    if ([self.delegate respondsToSelector:@selector(didCharacterTapped:)]) {
        [self.delegate performSelector:@selector(didCharacterTapped:) withObject:[NSNumber numberWithBool:YES]];
    }
    else {
        [self.delegate performSelector:@selector(didCharacterTapped:) withObject:[NSNumber numberWithBool:NO]];
    }
}

-(void)didCharacterTapped:(NSNumber *)tapped
{
     if (tapped.boolValue) {
    //[self startWelcomeBackCharacterAnimation];
     }
    else {
    }
}

您可以使用对象执行选择器，并且在选择器中您可以按照上面的代码访问对象值

形成您的评论，我可以看到您将tapGestureRecognizer 设置为特定的imageview，即self.characterImageView。

尝试将其分配给characterImageView中的parentview。

UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(characterImagedTapped)];
[self.characterImageView setUserInteractionEnabled:YES];
[self.view addGestureRecognizer:tapGestureRecognizer];
