Hi guys, how can i make my image remain in the position given by the rotation angle?
it keeps going back to the defalut position (0 degrees), and i want the animation to be completed at 45 degrees, so the image must stay at 45 degrees, not return to 0.

Thanks!!

This doesn’t work if the view is already rotated initially.

How to stop the image from returning to its start position? Just want it to stop if it spins a random number of turns and then be able to give it another spin.

I’m missing something but i don’t know what. Still beginner xcode programmer. I get an error saying Request for member ‘layer’ in something not a structure or union. I added the #import and added the layer to my button.

@ windrago

you should try duration to 0 and put angle of rotation to this
rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * direction];

Above code is untested.

I would like to implement your code in a way that the image flips vertically instead of rotate – How can I achieve that?

Thanks for the code. In y rotation, button is split in two parts and from center around y axis, and I cant see the half of the button, only one half is animating. This occurs when I use an UIImageView as background of button. Anybody has an idea?
