This gesture recognizer code below, which normally would scale a view from the center, does not when auto-layout is enabled in iOS6. The view seems to scale from it's origin when auto layout is enabled. Other affine transformations (particularly scale and rotate) are also not working as I expected. Anyone have this issue, or can enlighten me to the right way to handle this? - (IBAction)handlePinch:(UIPinchGestureRecognizer *)recognizer { recognizer.view.transform = CGAffineTransformScale(recognizer.view.transform, recognizer.scale, recognizer.scale); recognizer.scale = 1; } With Autolayout you

I'm probably missing something simple, but trying to do a simple "Ken Burns Effect" with an image view. First the code: [UIView animateWithDuration:20 delay:2 options:UIViewAnimationCurveLinear animations:^{ CGAffineTransform move = CGAffineTransformMakeTranslation(40, 40); CGAffineTransform zoom = CGAffineTransformMakeScale(1.2, 1.2); CGAffineTransform transform = CGAffineTransformConcat(zoom, move); self.imageView.transform = transform; } completion:^(BOOL finished){ NSLog(@"Done"); }]; I expected this to start with the image view at normal scale and expand it to 120% of the size over 20

I'm trying to do scale animation for UIButton when its clicked but what I'm trying to accomplish is when the button clicked I need the UIButton to be smaller to the inside then it comes back to its same size (like a bubble). I tried the following: button.transform = CGAffineTransformMakeScale(-1, 1) UIView.animateWithDuration(0.5, animations: { () -> Void in button.transform = CGAffineTransformMakeScale(1,1) }) Try this UIView.animate(withDuration: 0.6, animations: { self.button.transform = CGAffineTransform(scaleX: 0.6, y: 0.6) }, completion: { _ in UIView.animate(withDuration: 0.6) { self

Updating to iOS 8 and I've noticed an interesting one. I use CGAffineTransformScale to scale an image view to zero, the idea being that it disappears from the user's view neatly. It's work up to iOS8 but now it's not at all. Instantly the view is gone; blank! So originally I used: CGAffineTransform zoom = CGAffineTransformScale(CGAffineTransformIdentity, 0.0f, 0.0f); myImageView.transform = zoom; Why would this which worked up to now not work and when the functions haven't been depreciated? rob mayoff A CGAffineTransform is a 3x3 matrix, with its rightmost column permanently set to (0, 0, 1) T
