It looks like this whenever off:

虽然我更喜欢灰色背景。我真的必须使用UIImageView吗？

While I'd prefer more of a grey background. Do I really have to use a UIImageView?

推荐答案

以下是我改变iOS7 UISwitch填充颜色的方法。

Here is how I changed the fill color of my iOS7 UISwitch.

首先你需要导入QuartzCore。

First you need to import QuartzCore.

#import <QuartzCore/QuartzCore.h>

然后设置背景颜色并绕过UISwitch的角落。

Then set the background color and round the UISwitch's corners.

UISwitch *mySwitch = [[UISwitch alloc] initWithFrame:CGRectMake(0.0, 0.0, 51.0, 31.0)];
mySwitch.backgroundColor = [UIColor redColor];
mySwitch.layer.cornerRadius = 16.0; // you must import QuartzCore to do this.
[self addSubview:mySwitch];

这将为您提供具有自定义关闭（背景）颜色的UISwitch。

This will give you a UISwitch with a custom off (background) color.
