Cocoa Autolayout：内容拥抱与内容压缩阻力优先

问题：

I can't find a clear answer on Apple documentation regarding Cocoa Autolayout about the difference between content hugging and compression resistance. 关于Cocoa Autolayout关于内容拥抱和抗压缩性之间差别的Apple文档，我找不到明确的答案。

Can somebody explain their usages and difference ? 有人能够解释他们的用法和差别吗？
