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。
Masonry初级使用例子
1 // exp1: 中心点与self.view相同，宽度为400*400
2 -(void)exp1{
3 UIView *view = [UIView new];
4 [view setBackgroundColor:[UIColor redColor]];
5 [self.view addSubview:view];
6 [view mas_makeConstraints:^(MASConstraintMaker *make) {
7 make.center.equalTo(self.view);
8 make.size.mas_equalTo(CGSizeMake(400,400));
9 }];
10 }
11 //exp2: 上下左右边距都为10
12 -(void)exp2{
13 UIView *view = [UIView new];
14 [view setBackgroundColor:[UIColor redColor]];
15 [self.view addSubview:view];
16 [view mas_makeConstraints:^(MASConstraintMaker *make) {
17 make.edges.equalTo(self.view).with.insets(UIEdgeInsetsMake(10, 10, 10, 10));
18 // make.left.equalTo(self.view).with.offset(10);
19 // make.right.equalTo(self.view).with.offset(-10);
20 // make.top.equalTo(self.view).with.offset(10);
21 // make.bottom.equalTo(self.view).with.offset(-10);
22 }];
23 }
24 //exp3 让两个高度为150的view垂直居中且等宽且等间隔排列 间隔为10
25 -(void)exp3{
26 UIView *view1 = [UIView new];
27 [view1 setBackgroundColor:[UIColor redColor]];
28 [self.view addSubview:view1];
29 UIView *view2 = [UIView new];
30 [view2 setBackgroundColor:[UIColor redColor]];

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 for（遍历所有行) 2 for（遍历所以列） 3 //当前行约束根据上一行去设置 4 ......
下一个例子中，使用上面类似的方法
