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.

1 //these two constraints are exactly the same
2 
3 　　make.left.greaterThanOrEqualTo(label);
4 　　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.

1 //width >= 200 && width <= 400
2 make.width.greaterThanOrEqualTo(@200);
3 make.width.lessThanOrEqualTo(@400)
4 
5 //creates view.left = view.superview.left + 10
6 make.left.lessThanOrEqualTo(@10)
7 make.left.lessThanOrEqualTo(10)

3.设置边距

1     [self.webView mas_makeConstraints:^(MASConstraintMaker *make) {
2         make.edges.equalTo(self);
3     }];
