   //要使用系统的变灰，只需设置BackgroundImage即可
    [button setBackgroundImage:[UIImage imageNamed:@"blue.png"] forState:UIControlStateNormal];
    [button setTitle:aTitle forState:UIControlStateNormal];
  //变化后标题的颜色设置需设置状态为UIControlStateHighlighted
    [button setTitleColor:[UIColor lightGrayColor] forState:UIControlStateHighlighted];
