笔记masonry cell中图片和文字的自适应高

@end

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

        make.top.equalTo(10);

        make.leading.equalTo(16);

        make.trailing.equalTo(self.imgv_icon.mas_leading).offset(-16);

        make.height.greaterThanOrEqualTo(20);

        make.bottom.equalTo(-10);

    }];

这个效果如图:

使用优先级后效果:

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

        make.top.equalTo(10);

        make.leading.equalTo(16);

        make.trailing.equalTo(self.imgv_icon.mas_leading).offset(-16);

        make.height.greaterThanOrEqualTo(20).priorityHigh();

        make.bottom.equalTo(-10).priorityLow();

    }];
