Cocoa Autolayout：內容擁抱與內容壓縮阻力優先

問題：

I can't find a clear answer on Apple documentation regarding Cocoa Autolayout about the difference between content hugging and compression resistance. 關於Cocoa Autolayout關於內容擁抱和抗壓縮性之間差別的Apple文檔，我找不到明確的答案。

Can somebody explain their usages and difference ? 有人能夠解釋他們的用法和差別嗎？
