界: Encapsulation

封裝是要劃定清楚的界限。在網頁瀏覽器中，這可能意味著確保您的行動程式碼不會被其他行動程式碼濫用。在伺服器上，這可能意味著區分經過驗證的資料與未經驗證的資料、區分一個使用者的資料與另一個使用者的資料，或區分允許使用者查看的資料與不允許查看的資料。

Insecure Storage: Persistent Named Pasteboard

Objective-C
Swift

Abstract

具名剪貼板被設定為持續性時，可能會導致敏感資訊暴露。

Explanation

具名剪貼板使開發人員能與應用程式的其他部分或與具有相同團隊 ID 的其他應用程式共用資料。將具名剪貼板設定為持續性的功能已捨棄，這項功能可能會導致敏感資料暴露。當剪貼板被標記為持續性時，儲存在剪貼板中的資料能以未加密的方式儲存到本機儲存空間，並且在應用程式和裝置重新啟動時持續存在。
範例 1：在以下範例中，建立了具名剪貼板，並透過叫用 setPersistent:YES 將其設定為持續性。


  ...
  UIPasteboard *pasteboard = [UIPasteboard pasteboardWithName:@"myPasteboard" create:YES];
  [pasteboard setPersistent:YES];
  ...
