淡出UIView和切换UIView [英] Fade UIView and Switch UIView

问题描述

这是我从一个UIView切换到另一个UIView： self.view = MyView;
如何淡出一个视图到我的 MySecondView ？

This is how I switch from one UIView to another UIView: self.view = MyView; How would I fade out a view to my MySecondView?

推荐答案

您可以使用UIView的构建过渡代码， 。

You can use UIView's build in transition code to cross dissolve between them.

[UIView transitionFromView:self.view toView:MySecondView duration:0.25 options:UIViewAnimationOptionTransitionCrossDissolve completion:^(BOOL finished) {
    // What to do when its finished.
}];

您也可以使用类似这样的常规动画选项。我没有测试这个代码，因为我不在Xcode前面，但我一直使用它的标签和没有默认动画的东西。

You can also use the regular animation options with something like this. I haven't tested this code as I'm not in front of Xcode but I use it all the time for labels and things without default animations.

[UIView animateWithDuration:0.25 animations:^{
    [self.view setAlpha:0.0];
    self.view = mySecondView;
    [self.view setAlpha:1.0];
}];
