ios - get index or tag value from imageview tap gesture

Question

This is the image from app store whenever we search for any app. I also want to add the same scrollview concept in which it show the currentimage with small preview of previous and next image. I am able to make this view with the help of Sample code. But didn't find any solution that how to get index or tagvalue when user tap any of the image. So that I would be able to open the detail page for each image. If Someone has idea about this please help me.

Thanks in advance.

Add gesture recognizer to the necessary image view:

UITapGestureRecognizer *frameTapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(frameTapGesture:)];
[_imgView addGestureRecognizer:frameTapGesture];

Then in the gesture handler get access to the view gesture recognizer attached to:

- (void)frameTapGesture:(UITapGestureRecognizer*)sender
{
    UIView *view = sender.view; //cast pointer to the derived class if needed
    NSLog(@"%d", view.tag);
}
