    /**

    匿名类目:可以声明方法和变量,属性为private(不允许在外部调用,且不能被继承

    *//**

    发送数据的委托方,接收数据的时代理发(即代理的反向传值)

    委托方第一步:声明协议

    委托方第二步:声明代理指针

    委托方第三步:操作完成,告诉代理(即调用代理的方法)

    代理第一步:遵守协议

    代理第二步:成为代理

    代理第三步:实现协议方法

    */// %zd %zi 表示NSInteger// %g 表示数字去掉尾零//代码块路径/Users/ms/Library/Developer/Xcode/UserData/CodeSnippets#pragma mark - Xcode快捷键Control + A:移动光标到行首

    Control + E:移动光标到行末

    Control + D:删除光标右边的字符

    Control + K:删除本行
