iOS storyboard 設置 UIscrollview contentsize

stackoverflow.com/questions/1… 參考這篇文章。

目前我用的xcode11不須要答主那麼多步驟，經測試只要增長兩個keypath就能夠了

6: Click on your scrollview and click on Identity Inspector.

7: Add a User Defined runtime attribute with KeyPath of contentSize then type of SIZE and put in your content size. For me it is (320, 1000).

8: Add a runtime attribute with KeyPath frame with Type RECT and 0,0,320,416.

1.選中你的scrollview，點開identity InspectorM
2.在user defined runtime attribute欄裏增長兩個keypath，一個是contentSize，類型是SIZE，填入寬高，例如（320，1000）。一個是frame，類型是RECT， 例如0，0，320，416
