I am trying to drag a UIImageView around the iphone screen in my app. Currently The drag functionality I have set up is fine and dragging the image does move it around the screen, the trouble is that you don't have to drag the image view to move it, you can also drag anywhere on the screen and it will move the image. I am new to this platform so I can't really think about what to do to solve this issue. My current code to drag the image is: - (void) touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event { CGPoint pt = [[touches anyObject] locationInView:pig]; startLocation = pt; } - (void)

I have an ImageView with a png and I want to do this: when someone touch this imageview it's alpha change to 0.0, is it possible? (all without buttons) Yes, it is possible. For example you can do that with following steps: set image view's userInteractionEnabled property to YES - so it will receive touch events add UITapGestureRecongnizer to it in gesture handler set view's alpha to 0.0, you can do that with animation as well: [UIView animateWithDuration:0.5 animations:^(void){ imageView.alpha = 0.0f; }]; you can use UITapGestureRecognizer added to the UIImageView via addGestureRecognizer

This question already has an answer here : Closed 8 years ago . Possible Duplicate: How to do antialiasing on a rotated view? I'm trying to rotate some UIImageViews using this technique: imageView.transform = CGAffineTransformMakeRotation(r); where r is a float usually between -0.3 and 0.3. The problem is that the images (which are derived from square jpegs) that are rotated have jagged edges (pixellation), because they are at an angle after the transform. Is there a way to fix this so the edges are smooth (i.e. antialiased)? There is a key that you can set in Info.plist that enables
