推荐答案

将按钮添加到您的视图，去掉标题并设置类型切换（在检查的属性选项卡）。这里还设置了形象和按钮的备用图像是这样的：

Add a button to your view, remove the title and set the type to toggle(in the attributes tab of the inspector). Here also set the image and alternate image of your button like this:

这应该这样做。

如果你想使用自定义图像，你将不得不做编程方式是这样的：

If you want to use a custom image you will have to do it programatically like this:

NSString* path  = [[NSBundle mainBundle] pathForResource:@"myImage" 
					          ofType:@"png"];
NSURL* url  	= [NSURL fileURLWithPath:path];
NSImage *image  = [[NSImage alloc] initWithContentsOfURL: url];

[myButton setImage: image];

和分别为备用图片：

[myButton setAlternateImage: image2];
