Xhacker Liu扩展转换为Swift 3:

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

        setTitle(title, for: .normal)

        layoutIfNeeded()
        UIView.setAnimationsEnabled(true)
    }
}

一个方便的扩展动画按钮标题变化在Swift，发挥与默认实现很好:

import UIKit

extension UIButton {
  /// By default iOS animated the title change, which is not desirable in reusable views
  func setTitle(_ title: String?, for controlState: UIControlState, animated: Bool = true) {
    if animated {
      setTitle(title, for: controlState)
    } else {
      UIView.setAnimationsEnabled(false)
      setTitle(title, for: controlState)
      layoutIfNeeded()
      UIView.setAnimationsEnabled(true)
    }
  }
}

我已经做了一个Swift扩展来做这个:

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

        setTitle(title, forState: .Normal)

        layoutIfNeeded()
        UIView.setAnimationsEnabled(true)
    }
}

适用于我的iOS 8和9，与UIButtonTypeSystem。

(代码是Swift 2, Swift 3和Objective-C应该类似)

在Swift中，你可以使用:

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

我得到了它的工作组合的答案:

[[[button titleLabel] layer] removeAllAnimations];

    [UIView performWithoutAnimation:^{

        [button setTitle:@"Title" forState:UIControlStateNormal];

    }];

请注意:

当_button的"buttonType"为"UIButtonTypeSystem"时，以下代码无效:

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

当_button的"buttonType"为"UIButtonTypeCustom"时，上述代码有效。
