您可以根据UIControlState设置不同的图像和/或背景图像。例如，在图像的情况下：

[comment_notification setBackgroundImage:[UIImage imageNamed:@"1"] forState:UIControlStateNormal];//Normal state

[comment_notification setBackgroundImage:[UIImage imageNamed:@"2"] forState:UIControlEventTouchUpInside];//pressed and released state

[comment_notification setBackgroundImage:[UIImage imageNamed:@"3"] forState:UIControlEventTouchDown];//pressed state

或在背景颜色的情况下，添加目标：

[loginButton addTarget:self action:@selector(performLogin) forControlEvents:UIControlEventTouchUpInside];
[loginButton addTarget:self action:@selector(loginButtonPressed) forControlEvents:UIControlEventTouchDown];
[loginButton addTarget:self action:@selector(releasedButton:) forControlEvents:UIControlEventTouchUpOutside];

并在目标方法中，如buttonpressed：

- (void) buttonpressed:(UIButton*)button{

    [button setBackgroundColor:[UIColor blueColor]];
}
