How to set the progress tint color in UIProgressView
提问by Javier Calatrava Llavería
I would like to know how to set UIProgressView tint color. Sometimes, depending on the color, the default height does not allow to see properly the progress. How to fix that issue?
我想知道如何设置 UIProgressView 色调颜色。有时，根据颜色，默认高度不允许正确查看进度。如何解决这个问题？

This is for me the optimal way to do it:
这对我来说是最好的方法：
[progress setProgressTintColor:UIColorFromRGB(0xaa0000)];
where UIColorFromRGB is:
其中 UIColorFromRGB 是：
#define UIColorFromRGB(rgbValue) [UIColor colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 green:((float)((rgbValue & 0xFF00) >> 8))/255.0 blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]
(OPTIONAL): Sometimes, depending on the color, the progress is not properly appreciated and is necessary to increase the progress bar height:
（可选）：有时，根据颜色的不同，无法正确理解进度，并且有必要增加进度条高度：
[progress setTransform:CGAffineTransformMakeScale(1.0, 3.0)];
