Masonry 当需要把某个控件进行隐藏的时候有警告的解决方案

1     //查看全文
2             [self.moreBtn mas_makeConstraints:^(MASConstraintMaker *make) {
3                 make.top.equalTo (self.contentLabel.mas_bottom).with.offset (5);
4                 make.left.equalTo (self.contentView).with.offset (10);
5                 make.width.mas_equalTo (@60).priorityLow();
6                 make.height.mas_equalTo (@25).priorityLow();
7             }];

使用例子

如果（需要隐藏）{

    //查看全文
            [self.moreBtn mas_makeConstraints:^(MASConstraintMaker *make) {
                make.top.equalTo (self.contentLabel.mas_bottom).with.offset (5);
                make.left.equalTo (self.contentView).with.offset (10);
                make.width.mas_equalTo (@60).priorityLow();
                make.height.mas_equalTo (@25).priorityLow();
            }];

}else (不需要){

 //查看全文

            [self.moreBtn mas_makeConstraints:^(MASConstraintMaker *make) {

                make.top.equalTo (self.contentLabel.mas_bottom).with.offset (5);

                make.left.equalTo (self.contentView).with.offset (10);

                make.width.mas_equalTo (@0).priorityHigh();

                make.height.mas_equalTo (@0).priorityHigh();

            }];

}
