我创建了一个按钮,我希望在用户点击时更改其颜色.我看到了选项"setimagebackground ... forstate ......",但没有其他选项可以改变背景颜色.我在viewdidload中更改了y按钮的值,当我使用"settint color:[uicolor redcolor]"时,没有任何反应.我该怎么解决？这是我的代码:

    button1.layer.borderColor = [[UIColor purpleColor]CGColor];
    button1.layer.cornerRadius = 8.0f;
    button1.layer.masksToBounds = YES;
    button1.layer.borderWidth = 1.0f; 
    [button1.tintColor = [UIColor redColor]CGColor];
    [button1 setTintColor:[UIColor blueColor]];
    [button1 setTitleColor:[UIColor cyanColor] forState:UIControlStateNormal];
    [button1 setTitleColor:[UIColor redColor] forState:UIControlStateHighlighted];
    [button1 setTintColor:[UIColor redColor]];

谢谢!
