  • 基类是协议

appearence换肤

  • 不是所有的属性都能换肤,需要包含宏UI_APPEARANCE_SELECTOR
  • 需要在创建前先设置外观,否则无效
    - (IBAction)changeColor:(UISegmentedControl *)sender {
        switch (sender.selectedSegmentIndex) {
            case 0: // 蓝色
                [UISwitch appearance].onTintColor = [UIColor blueColor];
                break;
    
            case 1: // 红色
                [UISwitch appearance].onTintColor = [UIColor redColor];
                break;
    
            case 2: // 橙色
                [UISwitch appearance].onTintColor = [UIColor orangeColor];
                break;
        }
    
        // 重新添加控件
        [self.view removeFromSuperview];
        [[UIApplication sharedApplication].keyWindow addSubview:self.view];
    //    比下面的效果好
    //    [self.switch_ removeFromSuperview];
    //    [self.view addSubview:self.switch_];
    }
