Detect which image was clicked in UIImageView with animationImages

Question

We can specify images array for a UIImageview, and it will animate the images very nicely. I have subclassed the UIImageView class.

Now whe

Answer 1

I used the following workaround... Instead of using the built-in feature of animationImages, I animated the images with custom NSTimer

- (void)setBannerImagesArray:(NSArray *)bannerImagesArray
{
    _bannerImagesArray = bannerImagesArray;
    [self.timer invalidate];
    self.currentImageIndex = 0;
    self.image = [self.bannerImagesArray objectAtIndex:self.currentImageIndex];
    self.timer = [NSTimer scheduledTimerWithTimeInterval:1
                                                  target:self
                                                selector:@selector(displayNextImage)
                                                userInfo:nil
                                                 repeats:YES];

}

- (void)setup
{
    self.userInteractionEnabled = YES;
    UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(imageClicked)];
    [self addGestureRecognizer:tapGesture];

    self.bannerImagesArray = nil;
}

- (void)imageClicked
{
    NSLog(@"Image clicked index: %d", self.currentImageIndex);    
}

- (void)displayNextImage
{
    self.currentImageIndex = (self.currentImageIndex + 1) % self.bannerImagesArray.count;
    NSLog(@"Current Image Index %d", self.currentImageIndex);
    self.image = [self.bannerImagesArray objectAtIndex:self.currentImageIndex];
}
