How to stop unwanted UIButton animation on title change?

This works for custom buttons:

[UIView setAnimationsEnabled:NO];
[_button setTitle:@"title" forState:UIControlStateNormal];
[UIView setAnimationsEnabled:YES];

For system buttons you need to add this before re-enabling animations (thank you @Klaas):

[_button layoutIfNeeded];

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];
}];

In Swift you can use :

UIView.performWithoutAnimation {
    self.someButtonButton.setTitle(newTitle, forState: .normal)
    self.someButtonButton.layoutIfNeeded()
}
