动画 UIButton 的标题更改

问题描述

在这里我找到了如何使用现已弃用的 beginAnimations:context: 方法为 UIButton 的标题更改设置动画:

iPhone的UIBUtton标题动画

如何使用当前的 API 做同样的事情?

How to do the same thing using current APIs?

更新:

我尝试使用基于块的动画:

I've tried to use block-based animations:

NSTimeInterval animationDuration = animated ? 1.f : 0.f;
[UIView animateWithDuration:animationDuration delay:0.f options:UIViewAnimationOptionBeginFromCurrentState | UIViewAnimationOptionAllowUserInteraction animations:^{
    [button setTitle:newTitle forState:UIControlStateNormal];
    [button setTitleColor:newTitleColor forState:UIControlStateNormal];
} completion:nil];

颜色变化不是动画的.

推荐答案

使用积木:

[UIView transitionWithView:self.flipLabelButton duration:1 options:UIViewAnimationOptionTransitionFlipFromRight animations:^{

    [self.flipLabelButton setTitle:newText forState:UIControlStateNormal];

} completion:nil];
