How to stop unwanted UIButton animation on title change?

Question

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 fo         


        

Answer 1

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.

(The code is for Swift 2, Swift 3 and Objective-C should be similar)

You can simply create Custom button and it will stop animate while changing the title.

        UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
        [btn setTitle:@"the title" forState:UIControlStateNormal];

you also can do it in Storyboard checkbox: select the button in storyboard -> select the attributes inspector (fourth from left side) -> in the 'Type' drop down menu, select 'Custom' instead of 'System' that was probably selected.

Good luck!

Swift 4 version of Xhacker Liu answer

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

        setTitle(title, for: .normal)

        layoutIfNeeded()
        UIView.setAnimationsEnabled(true)
    }
}

I got the ugly animation problem when changing button titles in view controllers within a UITabBarController. The titles that were originally set in the storyboard showed up for a short while before fading into their new values.

I wanted to iterate through all subviews and use the button titles as keys to get their localized values with NSLocalizedString, such as;

for(UIView *v in view.subviews) {

    if ([v isKindOfClass:[UIButton class]]) {
        UIButton *btn = (UIButton*)v;
        NSString *newTitle = NSLocalizedString(btn.titleLabel.text, nil);
        [btn setTitle:newTitle];
    }

}

I found out that what's triggering the animation is really the call to btn.titleLabel.text. So to still make use of the storyboards and have the components dynamically localized like this I make sure to set every button's Restoration ID (in Identity Inspector) to the same as the title and use that as key instead of the title;

for(UIView *v in view.subviews) {

    if ([v isKindOfClass:[UIButton class]]) {
        UIButton *btn = (UIButton*)v;
        NSString *newTitle = NSLocalizedString(btn.restorationIdentifier, nil);
        [btn setTitle:newTitle];
    }

}

Not ideal, but works..

Maybe generating 2 animations and 2 buttons is a better solution, to avoid the problem that is appearing with animating and changing the text of a button?

I created a second uibutton and generated 2 animation, this solution works with no hickups.

    _button2.hidden = TRUE;
    _button1.hidden = FALSE;

    CGPoint startLocation = CGPointMake(_button1.center.x, button1.center.y - 70);
    CGPoint stopLocation  = CGPointMake(_button2.center.x, button2.center.y- 70);


    [UIView animateWithDuration:0.3 animations:^{ _button2.center = stopLocation;} completion:^(BOOL finished){_button2.center = stopLocation;}];
    [UIView animateWithDuration:0.3 animations:^{ _button1.center = startLocation;} completion:^(BOOL finished){_button1.center = startLocation;}];

In Swift you can use :

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