Question

In my application, i created imageView dynamically for each image and i have placed them in a scrollview.
How to generate an event to perform navigation action by clicking each image?

Answer 1

Quick and easy to implement

And an UITapGestureRecognizer to the UIImageView using addGestureRecognizer.

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(imageViewTapped:)];
singleTap.numberOfTapsRequired = 1;
singleTap.numberOfTouchesRequired = 1;
[theImageView addGestureRecognizer:singleTap];
[theImageView setUserInteractionEnabled:YES];

Now the following is triggered when the view is tapped:

- (void)imageViewTapped:(UIGestureRecognizer *)gestureRecognizer {
    NSLog(@"%@", [gestureRecognizer view]);
}

Alternative solution

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    if ([[touches anyObject] view] == theImageView)
    {
        // ImageView tapped.
    }
}
