iOS：UIImageView对动画之间的轻击手势不响应

Question

我使用交叉溶解动画在图像视图中显示多个图像，并点击图像显示有关图像的详细信息。 以下是代码的工作原理，但是当从一个图像到另一个图像设置动画时，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];
    }
}

除非执行以下代码，否则在imageview上单击即可正常工作！ 我必须点击3-4次以打开有关图像的详细信息。

- (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) {
                    }
     ];
}

有人可以建议我如何摆脱这个问题。

在这样的选项中设置UIViewAnimationOptionAllowUserInteraction

 [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) {
                    }
     ];
