在ios7中,我的UIButton标题在错误的时间动画进出——迟到。在iOS 6上不出现此问题。我用的是:

[self setTitle:text forState:UIControlStateNormal];

我更希望这能立即发生,而不是一个空白的框架。这种眨眼特别分散注意力,并将注意力从其他动画中转移开。

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)
    }
}

其他回答

将按钮类型设置为UIButtonTypeCustom,它将停止闪烁

将按钮类型更改为自定义表单界面生成器。

这对我很管用。

Swift 4版Xhacker刘回答

import Foundation
import UIKit
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)
    }
  }
}
