Prevent UIButton's setTitle:forState: animation

Question

I am using a NSTimer to update a UIButton's title every second.

It works but the text in the title blinks (animates to alpha 0 and back) automatically.

I tried to use button.layer.removeAllAnimations() with no luck, and no exceptions, so QuartzCore seems to be correctly linked.

Current non-working paranoid code:

UIView.setAnimationsEnabled(false)
UIView.performWithoutAnimation {
    button.setTitle(time, forState: .Normal)
    button.layer.removeAllAnimations()
        }
UIView.setAnimationsEnabled(true)

Did you try to wrap it with `UIView`'s `performWithoutAnimation(_ actionsWithoutAnimation: () -> Void)` (iOS >= 7)? Or `setAnimationsEnabled(_ enabled: Bool)`? — zrzka, Apr 14 '15 at 14:57

Make sure your button is a "custom" button and not a "system" button.

If you created it on a storyboard, then just change the Button Type. If you created it programmatically, then it should be:

UIButton *aButton = [UIButton buttonWithType:UIButtonTypeCustom];

Nice! Yet I can't understand why a system button refuses to obey to standard UIKit orders. – Rivera Apr 15 '15 at 14:00

I’ve made a Swift extension to do this:

extension UIButton {
    func setTitleWithOutAnimation(title: String?) {
        UIView.setAnimationsEnabled(false)

        setTitle(title, forState: .Normal)

        layoutIfNeeded()
        UIView.setAnimationsEnabled(true)
    }
}

Works for me on iOS 8 and 9, with UIButtonTypeSystem.

Works for me also with latest Swift release. Also using UIButtonTypeSystem in IB. Thanks! – ObjectiveTC Jul 31 '15 at 20:06
Tested on Swift 3.1, still works! – Paul Razvan Berg Jul 31 '17 at 18:03
This disables animations for the whole app just to not animate a button... it works, but it would be better to just use the custom UIButton type. – Alejandro Iván Dec 16 '18 at 15:45

You can perform Button changes inside the closure:

UIView.performWithoutAnimation {
    //Button changes
    button.layoutIfNeeded()
}

Hope this helps.

Too bad, same result. – Rivera Apr 14 '15 at 15:44
Also, it's shorter to call UIView.performWithoutAnimation { //Button changes } You still need to call layoutIfNeeded() – varu Feb 05 '16 at 14:47

I find this the correct answer! – Markicevic Nov 21 '18 at 09:50

The layoutIfNeeded after setting the setTitle call is all that's required. Wrapping it in UIView.performWithoutAnimation doesn't seem to do anything here. – stevex Sep 17 '20 at 16:41
