• IOS快速开发之常量定义


    ---恢复内容开始---

    在IOS开发中,有一些方法常常需要用的,但是有很长的方法名,这造成了代码长,写起来累,我们可以通过宏定义了解决这些问题

    比如说在代码布局的时候会遇上这样的问题,我们要获取上面一个的Y轴坐标,
    有两种方法

    通过坐标加上高度来计算

    xx.frame.origin.y+xx.frame.size.height
    

    还有一个略微简便的方法

    CGRectGetMaxY(xx.frame)
    

    都挺麻烦的,这时候就需要祭出宏定义来帮忙

    #define MaxY(v)            CGRectGetMaxY((v).frame) //纵坐标加上控件的高度
    

    通过这样的定义,下次我们获取Y坐标的时候只要轻轻的写上MaxY(xx)即可,是不是简单很多呢?

    类似的还有加载图片的方法

    #define IMAGENAMED(NAME)       [UIImage imageNamed:NAME]
    

    这样就非常的方便,

    下面是我整理的一个类

    这个在开发的时候可以略微的提高效率,OC的语法确实有点烦啊,赶快学swift吧,_
