代码约束2
Masonry是一个轻量级的布局框架，拥有自己的描述语法，采用更优雅的链式语法封装自动布局，简洁明了并具有高可读性，而且同时支持 iOS 和 Max OS X。Masonry是一个用代码写iOS或OS界面的库，可以代替Auto layout。Masonry的github地址：https://github.com/SnapKit/Masonry

- Masonry配置
- Masonry使用
- Masonry实例
Masonry配置
- 推荐使用pods方式引入类库，pod 'Masonry'，若不知道pod如何使用，情况我的另一篇文章： 提高ios开发效率的工具
- 引入头文件 #import "Masonry.h"
Masonry使用讲解
mas_makeConstraints 是给view添加约束，约束有几种，分别是边距，宽，高，左上右下距离，基准线。添加过约束后可以有修正，修正有offset（位移）修正和multipliedBy（倍率）修正。
语法一般是 make.equalTo or make.greaterThanOrEqualTo or make.lessThanOrEqualTo + 倍数和位移修正。
注意点1： 使用 mas_makeConstraints方法的元素必须事先添加到父元素的中，例如[self.view addSubview:view];
注意点2： masequalTo 和 equalTo 区别：masequalTo 比equalTo多了类型转换操作，一般来说，大多数时候两个方法都是 通用的，但是对于数值元素使用mas_equalTo。对于对象或是多个属性的处理，使用equalTo。特别是多个属性时，必须使用equalTo,例如 make.left.and.right.equalTo(self.view);
注意点3: 注意到方法with和and,这连个方法其实没有做任何操作，方法只是返回对象本身，这这个方法的左右完全是为了方法写的时候的可读性 。make.left.and.right.equalTo(self.view);和make.left.right.equalTo(self.view);是完全一样的，但是明显的加了and方法的语句可读性 更好点。

本例子使用的baseline去控制高度位置，这似乎不是太准，如果想要精准控制高度位置，可以使用一行一行添加的方法，每次当前行的top去equelTo上一行的bottom。 给个提示：
|
1
2
3
4
|
for
（遍历所有行)
for
（遍历所以列）
//当前行约束根据上一行去设置
......
