iPhone的UIBUtton标题动画

如何使用当前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。

推荐答案

使用块：

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

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

} completion:nil];
