我尝试设置按钮的背景颜色，但是不起作用。有人可以帮我吗？
- (IBAction)OrBoton:(id)sender {
[sender setBackgroundColor:(NSColor *)redColor];
}
But, if I try to setTitle, this works fine. Is unacessible the Backgroundcolor property? I don't recived any error when I Build and Debug, but don't works.
但是，如果我尝试 setTitle，这可以正常工作。无法访问 Backgroundcolor 属性？我在构建和调试时没有收到任何错误，但不起作用。
Thanks!

Well, finally, I opted for change image button from a colored image, because unfortunately, at the moment, this is impossible for me.
好吧，最后，我选择了从彩色图像更改图像按钮，因为不幸的是，目前这对我来说是不可能的。
