Masonry小结

一,容易混淆的问题

1.make.left.equal(xxx)的参数若为某个控件,则默认为以该控件的 left 为基准对照.

 //these two constraints are exactly the same

 　　make.left.greaterThanOrEqualTo(label);
 　　make.left.greaterThanOrEqualTo(label.mas_left);

2.宽度/高度可以使用常亮值, left/right/top/bottom/centerY/centerX 也可以用,但是代表的是相对位置.

 //width >= 200 && width <= 400
 make.width.greaterThanOrEqualTo(@);
 make.width.lessThanOrEqualTo(@)

 //creates view.left = view.superview.left + 10
 make.left.lessThanOrEqualTo(@)
 make.left.lessThanOrEqualTo()

3.设置边距

     [self.webView mas_makeConstraints:^(MASConstraintMaker *make) {
         make.edges.equalTo(self);
     }];
