UIButton 立即购买效果

我想在我的应用程序中制作一个“立即购买”按钮，其工作方式应与 App Store 中的按钮相同，但我不知道如何使用动画调整 UIButton 的大小。

我尝试了以下操作，但它立即调整了按钮的大小，而不是作为动画：

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:10.5];
[buyButton setFrame:CGRectMake(20, 115, 70, 21)];
[UIView commitAnimations];

其中“buyButton”是 UIButton。

我已经检查过这篇文章 UIButton AppStore 购买按钮动画，但似乎没有去工作。

原文

I want to make a "Buy Now" button in my Application, which should work the same way as the one in the App Store, but I dont know how to resize the UIButton with an animation.

I have tried the following, but it resized the button at once and not as an animation:

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:10.5];
[buyButton setFrame:CGRectMake(20, 115, 70, 21)];
[UIView commitAnimations];

Where the "buyButton" is a UIButton.

I've checked ou this post UIButton AppStore buy button animation, but is does not seem to work.

试试这个：

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:duration];

CGAffineTransform scale = CGAffineTransformMakeScale(scalingFactorX, scalingFactorY);
buyButton.transform = scale;

[UIView commitAnimations];

使用 CGAffineTransform 可能会有所帮助。我还没有尝试过这个，但是，它应该有效。

Try this:

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:duration];

CGAffineTransform scale = CGAffineTransformMakeScale(scalingFactorX, scalingFactorY);
buyButton.transform = scale;

[UIView commitAnimations];

Using CGAffineTransform may help. I have not tried this, however, it should work.
