推荐答案

如果我正确理解这个问题听起来像你想要增加iOS7中进度视图的高度，以前在iOS6中使用的代码不再有效。

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.

我最近必须解决类似问题而且我通过在Interface Builder中向进度视图添加约束并通过约束显式设置高度来实现此目的。此解决方案需要使用自动布局，因此请确保已打开。

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：Size Inspector上的Height属性对于Progress View显然是灰色的，无法更改 - 但是我已经在Progress View本身上定义了一个约束并设置了约束的高度为50分，实际上反映在IB中。

从我看到的iOS6进度条有一个静态高度值，所以如果你也想支持iOS6，那么就需要采用另一种方法。

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.
