iPhone應用程序運行在ipad上的問題

Question

我的iPhone應用程序在iPad上運行時遇到了問題。我在第一個屏幕中使用了相機覆蓋視圖（應用程序啓動時啓動），但是當我導航到其他屏幕時，它的頂部空間。這隻出現在iPad上，iPhone上的所有作品都很棒。

在這裏被安裝圖像顯示空白屏幕

Answer 1

解決，

使用下面的行顯示在狀態欄

[[UIApplication sharedApplication]setStatusBarHidden:NO]; 

而且它顯示一個黑條，而不是一個空格。

謝謝大家的合作

Answer 2

這可能是因爲狀態欄，因爲它顯示在iPad的頂部，它存在於iPhone的白色地方。
