I've got a Selected-state and a Normal-state for an UIButton that both are UIImages. When a button is touched, I'd like it to hit the selected-state and then animate back to the normal-state over the period of one second. I've set the following animation when the UIButton* btn is pressed, but it just switches right back to deselected state again. How should I go about achieving this?
[btn setSelected:YES];
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.0f];
[btn setSelected:NO];
[UIView commitAnimations];
Cheers

Since
selected
is not an animatable property, that won't work (as you've found out). My solution would be to have the selected state of the btn be in a separate UIImageView directly below the button in the exact same location. Then in the action for tapping the button:Note I also added the
begin/endIgnoringInteractionEvents
calls so the user can't tap on the button while it's fading back to its normal state. If you want to allow that, replace thebegin/end
calls with[UIView setAnimationBeginsFromCurrentState];
