「查看層次未準備好約束...」

2014-08-29 91 views

對於那些已經通過cs193p的人，我實際上正在完成當前最新課程的第三作業。「查看層次未準備好約束...」

我甚至用Martin Mandl的優秀博客作爲解決大多數問題的參考。

但是！

對於那些不知道，我建立一個簡單的標籤欄應用程序。代碼本身的所有功能都在工作。我可以暫停，直到AFTER - （void）viewDidLoad發生錯誤。這是一個與故事板相關的問題。

這是整個調用堆棧和前面的錯誤細節。有任何想法嗎？

向下滾動了一下：

View not found in container hierarchy: 
<UIButton: 0x8d59700; frame = (20 72; 40 40); opaque = NO; autoresize = RM+BM; layer = <CALayer: 0x8d597f0>> 
That view's superview: NO SUPERVIEW

這UIButton沒有上海華。如果您是在IB中製作的，請查看所有視圖的樹視圖;它可能不在正確的位置。

我確實在IB中創建了它，很好的捕捉到了NO NOERVERVEWEW。但是，如果我在20 72刪除了該按鈕，則會在68 72處列出下一個按鈕的錯誤。 – Meshach 2014-08-29 19:40:29

也許多個按鈕沒有超級視圖。 – 2014-08-29 20:43:20

我從頭開始重建整個視圖。這兩個單獨的場景使用SAME父視圖控制器（儘管它們的擴展略有不同），但有一個正常工作，但這個失敗。 – Meshach 2014-08-29 22:30:49
