[[UIProgressView appearance] setFrame:CGRectMake(20, 100, 280, 100)];

推荐答案

如果我对问题理解正确的话，听起来你想在 iOS7 中增加进度视图的高度，而你之前在 iOS6 中使用的代码是没有工作时间更长.

If I am understanding the question correctly it sounds like you want to increase the height of the progress view in iOS7, and the code you used previously in iOS6 is no longer working.

我最近不得不解决一个类似的问题，我通过向 Interface Builder 中的进度视图添加约束并通过约束显式设置高度来做到这一点.此解决方案将需要使用自动布局，因此请确保您已将其打开.

I had to solve a similar problem recently and I did this by adding a constraint to the progress view in Interface Builder and setting the height explicitly through the constraint. This solution will require the use of Auto-Layout, so be sure that you have that turned on.

显示:尺寸检查器上的高度"属性对于进度视图明显变灰并且无法更改 - 但是我已经在进度视图本身上定义了一个约束并将约束的高度设置为 50 点，这实际上反映在IB中.

据我所知，iOS6 Progress Bars 具有静态高度值，因此如果您还想支持 iOS6，则需要另一种方法.

From what I've seen iOS6 Progress Bars have a static height value, so if you also want to support iOS6 then another approach will be necessary for that.
