Drag and Drop UIImageView(s) inside UIView

i have put a UIView inside the xib and made the IBOutlet for this as property name - sampleView.

This UIView's x and y position is as per my project. So no need to worry about the parent view x and y position. Because we can make it relative to superview controller as follow:

//imagesView is Mutable Array and contains all UIImages.

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

UITouch *touch = [[event allTouches] anyObject];

    

    for(int i=0;i<imagesInView.count;i++)

    {

        UIImageView *imgView = [imagesInView objectAtIndex:i];

        if (CGRectContainsPoint([imgView frame], [touch locationInView:self.secondFullImageView])) {

            //if ([touch tapCount] == 2)

                //[imgView setupNextDisplayString];

            CGPoint touchPoint = [touch locationInView:self.sampleView];//Here you need to concentrate for your UIImageView Parent

            [UIView beginAnimations:nil context:NULL];

            [UIView setAnimationDuration:0.3];

            imgView.center = touchPoint;

            CGAffineTransform transform = CGAffineTransformMakeScale(1.2, 1.2);

            imgView.transform = transform;

            [UIView commitAnimations];

            return;

        }

   }

}

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {

    UITouch *touch = [[event allTouches] anyObject];

    for(int i=0;i<imagesInView.count;i++)

    {

        UIImageView *imgView = [imagesInView objectAtIndex:i];

        if (CGRectContainsPoint([imgView frame], [touch locationInView:self.sampleView])) {

            CGPoint location = [touch locationInView:self.sampleView];

            imgView.center = location;

        }

}

}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {

    UITouch *touch = [[event allTouches] anyObject];

    

    for(int i=0;i<imagesInView.count;i++)

    {

        UIImageView *imgView = [imagesInView objectAtIndex:i];

        if (CGRectContainsPoint([imgView frame], [touch locationInView:self.sampleView])) {

            //if ([touch tapCount] == 2)

            //[imgView setupNextDisplayString];

            [UIView beginAnimations:nil context:NULL];

            [UIView setAnimationDuration:0.3];

            CGAffineTransform transform = CGAffineTransformMakeScale(1, 1);

            imgView.transform = transform;

            [UIView commitAnimations];

            return;

        }

    }

}
