我收到了第一份崩潰報告，但我無法弄清楚問題所在。幸運的是，由於這次崩潰來自我的同事，我可以直接在他的iPhone上測試錯誤，並在他的手機上安裝開發版本。如何調試iPhone應用程序崩潰日誌。僅在App Store購買的版本中崩潰，未開發
然而，奇怪的是，當我從我的電腦上安裝並在他的設備上運行開發版本時，沒有崩潰; 只有當應用程序從App Store下載並安裝時纔會出現崩潰。 到目前爲止，我無法在任何其他設備上重現錯誤（受影響的設備是iPhone 3G固件4.2.1，所有操作系統運行速度都很慢）。該行被從一個UITableViewController（ItemsListTableViewController）中選擇，在這點的細節視圖應該出現後
所述的碰撞發生，但詳細視圖（ItemDetailViewController）的viewDidLoad中施工中應用程序崩潰。
尤其是該問題似乎在類LocationPathView（ItemDetailViewController視圖的子視圖）中進行了本地化。 ItemDetailViewController是UITableViewController的子類，並從viewDidLoad中的nib中加載其tableHeaderView：
[[NSBundle mainBundle] loadNibNamed：@「ItemDetailHeaderView」owner：self options：nil]; （LocationPathView是tableHeaderView的一部分）
當筆尖文件被加載，LocationPathView :: awakeFromNib稱爲然後LocationPathView :: layoutSubviews被調用。崩潰似乎源於layoutSubviews。 在layoutSubviews內我執行動畫： [UIView beginAnimations：nil context：nil]; [UIView setAnimationDuration：0.2]; 由於某些原因，此動畫可能會因慢速設備崩潰而創建嗎？在layoutSubviews中動畫是否正確？
我會感謝任何幫助，
馬爾科

我以標準方式構建我的發行版：我在Build Settings - > Code Signing Identity中選擇了我的發行版配置文件，以進行調試和發佈行，然後產品 - >存檔。尚未使用特設版本進行測試，我將盡快發佈結果 – ggould75 2011-05-06 07:13:56
類似的事情發生在我身上。特別是爲UITableView中的節標題創建一個UIView。如果我存檔並「共享」我的應用程序，然後將它安裝在iPhone 4上，一切都很好。如果我「提交」相同的版本，我得到這個： CALayerInvalidGeometry'，原因：'CALayer範圍包含NaN： – Antonio 2011-05-17 11:15:09
