xcode中单选按钮的问题

Question

我在xcode中的ios中的单选按钮有问题。我想在两个按钮（按钮上的图像）的帮助下实现这一点。如何让两个按钮像单选按钮一样？有什么帮助吗？

UIButton *radioBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[radioBtn setImage:[UIImage imageNamed:@"radioOff.png"] forState:UIControlStateNormal];
[radioBtn setImage:[UIImage imageNamed:@"radioOn.png"] forState:UIControlStateSelected];
[radioBtn setBackgroundColor:[UIColor clearColor]];
[radioBtn addTarget:self action:@selector(myfunc) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:radioBtn];
