TapRecognizer in View and Scrollview (to drag and drop images in and out of Scrollvie

[BarryK88]

I created a view and a scrollview. They both have images inside their view. I'd like to implement a method which makes it possible for the user to drag images in and out of the scroller.

I implemented a UITaprecognizer within my project however I'm not sure how to implement the next steps in my code.

like:

* how to see which image is doubletapped.
* how to make sure that only the doubletapped image is draggable.
* how to drag my image inside or outside a scrollview. (by means of a CGIntersectRect) wich replaces my image in the scroller to the image within my view.

Here's a snippit from my code

- (void)viewDidLoad{
    UITapGestureRecognizer* tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleTap:)];
    tap.numberOfTapsRequired = 2;
    [image1 addGestureRecognizer:tap];
    [image2 addGestureRecognizer:tap];
    [image3 addGestureRecognizer:tap];
[scroller addGestureRecognizer:tap];
    [self.view addGestureRecognizer:tap];
    [tap release];

[super viewDidLoad];
}

-(IBAction)handleDoubleTap:(UITapGestureRecognizer *)recognizer {

    NSLog(@"an image is doubletapped");
}
- (void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *) event {

    UITouch *touch = [[event allTouches] anyObject];
    CGPoint location = [touch locationInView:self.view];

if ([touch view] == image1) {
        image1.center = location;
    }
if ([touch view] == image2) {
        image2.center = location;
    }
if ([touch view] == image3) {
        image3.center = location;
    }
[self checkcollision];
}

-(void)checkcollision {

//check collision here
}

Help is greatly appreciated!
