Answer 1

It's Simple, you can use it like this :

yourImageView = [[UIImageView alloc] initWithImage:yourImage];
[yourScrollView addSubview:yourImageView];
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
[yourImageView addGestureRecognizer:singleTap];
[sibgleTap release];

GoodLuck.

I got answer after googling, I dissable all gesture of scrollview and then set userinteraction of UIImageview YES, I dissable gesture of UIScrollview using the this code

 for (UIGestureRecognizer* recognizer in [scrollviewFrame1 gestureRecognizers]) {
            if ([recognizer isKindOfClass:[UIPinchGestureRecognizer class]]) {
                [recognizer setEnabled:NO];
            }
        }
