使2动画中自定义视图 [英] Make 2 animations in Custom View

问题描述

林创建一个自定义视图，它包含例如刷新，*的 LayoutSubviews 的*，按照此<一个方法href=\"http://www.raywenderlich.com/1768/uiview-tutorial-for-ios-how-to-make-a-custom-uiview-in-ios-5-a-5-star-rating-view\"相对=nofollow>教程

Im creating a custom view, it contains methods like Refresh,*LayoutSubviews*, following this tutorial

我要做个动画标签越来越大，它的全宽，然后回到0宽度。使用这种code在刷新法林：

I want a label to be animated growing, to it's full width and then back to 0 width. Im using this code in "refresh" method:

[UIView animateWithDuration:1.3 animations:^{
        CGRect frame = CGRectMake(50, 15, 140, 20);
        [labelFav setFrame:frame];
    } completion:^(BOOL finished) {
        //[labelFav setHidden:YES];
        [UIView animateWithDuration:1.3 animations:^{
            CGRect frame = CGRectMake(50, 15, 0, 20);
            [labelFav setFrame:frame];
        }];

    }];

在code适用于任何其他的看法，但由于这是由于某种原因完工块不执行自定义视图。
什么情况是，它只做第一个块。我在完成块设置一个断点，它停在那里，但动画犯规发生。我试图setHidden标签，仍然它不发生的。

The code works on any other view, but since this is a Custom view by some reason the completion block is not executing. What happens is that it only does the first block. I set a breakpoint in the "completion" block and it stops there but the animation doesnt happen. I tried to setHidden the label and still it doesnt happen.

任何想法？

推荐答案

另一种方式来解决问题。 测试。

Another way to solve problem. Tested.

[UIView animateWithDuration:1.3 animations:^{

    CGRect frame = CGRectMake(50, 15, 140, 20);
    [labelViewForFav setFrame:frame];

} completion:^(BOOL finished) {

   [UIView animateWithDuration:1.3 animations:^{

                CGRect frame = CGRectMake(50, 15, 0, 20);
                [labelViewForFav setFrame:frame];

        } completion:^(BOOL finished) {

        }];
}];

问题是，当你做的UILabel宽度小于当前的宽度。动画做得不好。动画不可见的只是跳到最后一帧。

Problem is When you make UIlabel width less than its current width. Animation is not done properly. Animation not visible just jump to final frame.

解决它把​​你的标签在一个视图改变这个视图的大小，它会正常工作。

to solve it Put your label in a view change the size of this view and it will work properly.
