动画UIButton的标题更改

Question

在这里,我找到了如何UIButton使用现已弃用的beginAnimations:context:方法来动画的标题更改:

适用于iPhone的UIBUtton标题动画

如何使用当前的API做同样的事情？

更新:

我试过使用基于块的动画:

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];

颜色更改不是动画.

Answer 1

使用块:

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

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

} completion:nil];

Answer 2

迅速

UIView.transition(with: button, duration: 0.5, options: .transitionCrossDissolve, animations: {
  self.button.setTitle("WOW, new title", for: .normal)
  self.button.setTitleColor(UIColor.red, for: .normal)
}, completion: nil)

Answer 3

除了AnimationGroups之外,通常还有两种动画,一种是属性动画,另一种是动画内容,转换或任何不能使用属性做动画的动画.所以第二个解决方案是您的选择,您可以通过两种方式实现这一目标:使用CATransition:

CATransition *transition = [CATransition animation];
transition.type = kCATransitionFade;
transition.duration = 1;
[button.layer addAnimation:transition forKey:kCATransition];
[button setTitle:newTitle forState:UIControlStateNormal];
[button setTitleColor:newColor forState:UIControlStateNormal];

另一种方式是使用UIKit块,如@jjv360所说,但你不能在其中设置颜色动画,因为显然颜色不能翻转.
