破譯崩潰報告 - iOS - xCode

我試圖複製我的應用程序中偶爾發生的錯誤。我有下面的崩潰報告。我是否認爲應用程序崩潰是由於NSDictionary沒有特定鍵的值？還有什麼我可以從報告中推斷出來嗎？其崩潰破譯崩潰報告 - iOS - xCode

    if (responseCallback) {

這是沒有必要，由於NSDictionary只有它崩潰請分析相同從你的viewDidload方法的ContractViewController –

如果它是字典，那麼你可能會看到：*** - [__ NSPlaceholderDictionary initWithObjects：forKeys：count： ]：試圖從對象[0]或類似的地方插入nil對象。在這裏閱讀：http：//www.raywenderlich.com/23704/，看看你能不能找出任何東西。 – Mikael

添加控制檯輸出請 –

所述的碰撞發生在文件WebViewJavascriptBridge.m中，管線95在該方法中[WebViewJavascriptBridge _sendData:responseCallback:handlerName:]。

該行在[__NSPlaceholderDictionary initWithObjects:forKeys:count:]中導致異常。由於崩潰報告中沒有顯示異常消息，並且您不提供該地點的任何源代碼，所以我們只能假定發生了什麼。

一個假設是，您正在創建一個包含nil值或密鑰的字典。但是如果沒有代碼或者你真的在調試它，這只是一個假設。

Kemi - 謝謝 - 這非常有幫助。我在上面的方法中添加了 - 你能找到其他的東西嗎？ – GuybrushThreepwood

'數據'是'無'？ – Kerni

對 - 謝謝！ – GuybrushThreepwood
