【iOS】Masonry 自动布局 MASViewConstraint.m:207 错误

问题详情：

Assertion failure in -[MASViewConstraint addConstraintWithLayoutAttribute:], ~/Pods/Masonry/Masonry/MASViewConstraint.m:207

 

报错原因：

make.right.equalTo([_imageView superview]).right.with.offset(-10);
make.bottom.equalTo([_imageView superview]).bottom.with.offset(-10);

 

当时想当然的就这么写了，仔细查看了 Github 链接，才发现了自己的失误。正确写法如下：

make.right.equalTo([_imageView superview].mas_right).with.offset(-10);
make.bottom.equalTo([_imageView superview].mas_bottom).with.offset(-10);

 

PS: 报此错误的的还可能是不小心把 with 误写成 width
