iOS：UIImageView沒有響應動畫之間的水龍頭手勢

Question

我有多個圖像顯示在ImageView中使用交叉溶解動畫和錄製圖像顯示圖像細節。以下是代碼工作，但在從一個圖像到另一個圖像進行動畫處理時，點擊imageview失敗。

用於將單擊手勢識別器附加到UIImageview並啓動動畫計時器的代碼。

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的一個水龍頭工作正常，除非以下代碼執行！我必須點擊3-4次來打開有關圖像的細節。

- (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) { 
        } 
    ]; 
} 

有人可以請建議我如何擺脫這個問題，請。而在動畫的選項

集UIViewAnimationOptionAllowUserInteraction像這樣

[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) { 
        } 
    ];
