Masonry的使用和介绍



//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。

// exp1: 中心点与self.view相同，宽度为400*400
-(void)exp1{
UIView *view = [UIView new];
[view setBackgroundColor:[UIColor redColor]];
[self.view addSubview:view];
[view mas_makeConstraints:^(MASConstraintMaker *make) {
make.center.equalTo(self.view);

//exp2: 上下左右边距都为10
-(void)exp2{
