蘋果是否允許自定義UIAlertView？

Question

我準備通過繼承UIAlerView來提交這樣的定製。它的佈局完全基於UIAlertView的給定地形，沒有讀取任何私有屬性。 App Store審覈過程是否可以接受這種定製？

Answer 1

沒有人，但蘋果可以充分地回答這個問題，所以最好的辦法是把它放到測試。我認爲您必須問自己的主要問題是：我違反了Apple開發人員協議中的任何規定嗎？如果沒有，請提交您的應用程序。如果您擔心拒絕，請考慮採取其他方式作爲備份，並準備在出現問題時提交。

不是你問過，但我也會認爲蘋果設計的這種改變不是很直觀。你的意思是轉換意思是「也從moquus中刪除？」因爲你已經有一個大的刪除按鈕。如果開關關閉，那麼刪除按鈕刪除了什麼？

Answer 2

的實際問題的答案是沒有 - 蘋果不允許UIAlertView中要被繼承。從UIAlertView中的文檔：

子類注

的UIAlertView中類擬用作原樣，並且不支持 子類。該類的視圖層次結構是私有的，並且不得修改 。
