iOS：UIImageView没有响应动画之间的水龙头手势

Question

我有多个图像显示在ImageView中使用交叉溶解动画和录制图像显示图像细节。以下是代码工作，但在从一个图像到另一个图像进行动画处理时，点击imageview失败。

用于将单击手势识别器附加到UIImageview并启动动画计时器的代码。

self.imageView.userInteractionEnabled = YES; 
    self.singleTapGestureRecogniser = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(showDetails)]; 
    self.singleTapGestureRecogniser.numberOfTapsRequired = 1; 
    self.singleTapGestureRecogniser.cancelsTouchesInView = NO; 

    [self.imageView addGestureRecognizer:self.singleTapGestureRecogniser]; 

    [self startAnimationTimer]; 

- (void)startAnimationTimer 
{ 
    if(!self.timer && ![self.timer isValid]) { 
     self.timer = [NSTimer scheduledTimerWithTimeInterval:5.0 
           target:self 
           selector:@selector(startAnimation) 
           userInfo:nil 
           repeats:YES]; 
     [self.timer fire]; 
    } 
} 

上ImageView的一个水龙头工作正常，除非以下代码执行！我必须点击3-4次来打开有关图像的细节。

- (void)startAnimation 
{ 
    [UIView transitionWithView:self.imageView duration:2.0 
         options:UIViewAnimationOptionTransitionCrossDissolve 
        animations:^ { 
         currentImageIndex = ++currentImageIndex % self.images.count; 
         [self.imageView setImage:[[self.images objectAtIndex:currentImageIndex] image]]; 
        } completion:^(BOOL finished) { 
        } 
    ]; 
} 

有人可以请建议我如何摆脱这个问题，请。而在动画的选项

集UIViewAnimationOptionAllowUserInteraction像这样

[UIView transitionWithView:self.imageView duration:2.0 
         options:UIViewAnimationOptionTransitionCrossDissolve | UIViewAnimationOptionAllowUserInteraction 
        animations:^ { 
         currentImageIndex = ++currentImageIndex % self.images.count; 
         [self.imageView setImage:[[self.images objectAtIndex:currentImageIndex] image]]; 
        } completion:^(BOOL finished) { 
        } 
    ];
