iOS崩潰日誌解釋

我的應用程序商店因爲崩潰而被拒絕。但是，我無法在多個硬件設備和模擬器上重現崩潰。我用符號表示了崩潰日誌，看起來這個問題發生在一個代碼區域，在這個代碼區域，應用程序從服務器獲取一些數據並關閉一個UIAlertController，通知用戶「Please wait ...」。下面是崩潰登錄。任何想法查明原因將不勝感激。iOS崩潰日誌解釋

您已經測試過的應用程序沒有連接到互聯網？ – Flexicoder

是的，我嘗試了沒有互聯網連接，但仍然沒有崩潰。還嘗試在MAC上使用本地IPv6 NDS64/NAT64網絡。 – SKim

我建議你不與UIAlertController（或任何其它的UIKit API）交互外主線程（又名Thread 0以上）雙重檢查。許多UIKit API被設計爲從主線程僅使用只有。

值得注意的是，事故發生在Thread 1 ...

如果您有任何疑問，包裝與呼叫：

DispatchQueue.main.async { 
    // Call UIAlertController code here... 
}

堆棧跟蹤清楚地顯示視圖控制器正在後臺線程上被解僱。那很糟。此答案顯示正確的解決方案。在DispatchQueue.main.async中調用'dismiss'。 – rmaddy

@rmaddy你是對的！我真的不知道我是如何錯過墜毀線程中的很多'UIKit'調用，哈哈:) –

感謝Paulo和rmaddy。我會重新檢查控制器解僱電話。爲了我的薰陶，爲什麼我沒有看到在後臺線程中被解僱的崩潰？我已經利用了這個特殊的功能幾十次，從未遇到過崩潰。 – SKim
