Swift – How to stop unwanted UIButton animation on title change

ios7objective cswiftuibuttonuikit

In iOS 7 my UIButton titles are animating in and out at the wrong time – late. This problem does not appear on iOS 6. I'm just using:

[self setTitle:text forState:UIControlStateNormal];

I would prefer this happens instantly and without a blank frame. This blink is especially distracting and draws attention away from other animations.

Use the performWithoutAnimation: method and then force layout to happen immediately instead of later on.

[UIView performWithoutAnimation:^{
  [self.myButton setTitle:text forState:UIControlStateNormal];
  [self.myButton layoutIfNeeded];
}];

Ios – How to add multi-line text to a UIButton

For iOS 6 and above, use the following to allow multiple lines:

button.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;
// you probably want to center it
button.titleLabel.textAlignment = NSTextAlignmentCenter; // if you want to 
[button setTitle: @"Line1\nLine2" forState: UIControlStateNormal];

For iOS 5 and below use the following to allow multiple lines:

button.titleLabel.lineBreakMode = UILineBreakModeWordWrap;
// you probably want to center it
button.titleLabel.textAlignment = UITextAlignmentCenter;
[button setTitle: @"Line1\nLine2" forState: UIControlStateNormal];

generally, just do these two things:

choose "Attributed Text"
on the "Line Break" popup select "Word Wrap"
