iOS 比masonry更简单的适配（比例适配）

前言

众所周知，masonry是基于autolayout的适配，使用起来还是相对来说比较简单的。但是由于本人更倾向于比例适配（因为之间学过一段时间Android，对Android中的比例适配比较喜欢)所以一直以来都用比例适配,最近几天朋友给我了一个自己写的demo，正好借着前几天刚学习的UIResponder给大家讲解一下这个demo,希望对大家有帮助。在此也对我这个朋友，表示崇高的敬意。

iOS中的CGRectmake(……)方法讲解

首先我们可以根据CGRectmake（……）方法跳转至CGGeometry.h可以看到我们平时所用的一些常用方法，例如：

CGPoint CGPointMake(CGFloat x, CGFloat y);
CGSize  CGSizeMake(CGFloat width, CGFloat height);
CGRect  CGRectMake(CGFloat x, CGFloat y, CGFloat width,CGFloat height);

对于这些方法，不做太多解释，相信只要爬一下文档，就可以简单的使用。这里呢，借图简单的说明一下。

思考

那么看到这里，如何写一个适配文件，供全局调用呢?
其实写一个category去扩展这个类，然后去添加一个pch文件，在pch文件中#import就可以实现调用。其实这样子的思维就比较局限了，大家可以试想，一般去设置坐标的绝对是一个UIView，那么是不是只要去扩展UIView的父类，就可以让所有的UIView去按照category中的方法进行布局？答案是肯定的。所以前几天介绍的UIResponder便派上了用场。我们可以去扩展UIResponder去实现布局。废话不多说，上代码：
UIResponder+Adapt.h

/**

  需要适配的地方 替换 CGRectMake => CGRectMakeAdapt  \
  e.g.   button.frame = CGRectMake(100, 100, 100, 100);
  =>  button.frame = CGRectMakeAdapt(100, 100, 100, 100)

这些代码其实不难，但是整理出来还是需要一番功夫的，所以应该向我的那位朋友致敬：曾墨
引用很简单，首先得导入头文件，在这里呢，建议建立pch文件一次性导入，然后呢，你会发现，你可以通过绝对布局，实现所有屏幕的适配，最主要的是：方法还跟以前超级类似：主要调用这几个方法：
CGPoint CGPointMakeAdapt(CGFloat x, CGFloat y)；
CGSize CGSizeMakeAdapt(CGFloat width, CGFloat height)；
CGRect CGRectMakeAdapt(CGFloat x, CGFloat y, CGFloat width, CGFloat height)；
UIEdgeInsets UIEdgeInsetsMakeAdapt(CGFloat top, CGFloat left, CGFloat bottom, CGFloat right)；
