Masonry的使用

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。

这里是Masonry给我们的属性：

@property (nonatomic, strong, readonly) MASConstraint *left;      //左侧@property (nonatomic, strong, readonly) MASConstraint *top;       //上侧@property (nonatomic, strong, readonly) MASConstraint *right;     //右侧@property (nonatomic, strong, readonly) MASConstraint *bottom;    //下侧@property (nonatomic, strong, readonly) MASConstraint *leading;   //首部@property (nonatomic, strong, readonly) MASConstraint *trailing;  //尾部@property (nonatomic, strong, readonly) MASConstraint *width;     //宽@property (nonatomic, strong, readonly) MASConstraint *height;    //高@property (nonatomic, strong, readonly) MASConstraint *centerX;  //横向居中@property (nonatomic, strong, readonly) MASConstraint *centerY;  //纵向居中@property (nonatomic, strong, readonly) MASConstraint *baseline; //文本基线

现在我们纯代码来创建一个UITableViewCell并使用Masonry给Cell里面的控件设置约束。如图所示的Cell

代码如下：

以上代码已经给Cell里面的控件设置好了约束，现在我们把它加载到UITableView中查看效果

运行后得到效果如图：
