該設備是帶有iOS 9.2的iPhone 6s Plus。使用Titanium Studio時，當我以調試模式運行並逐步執行代碼時，應用程序運行良好。但是，當我簡單地「運行」它（通過USB連接到筆記本電腦的設備）或者將.ipa文件安裝在adhoc發行版中時，應用程序一旦啓動就會崩潰。 「運行」時，Titanium絕對沒有生成日誌。當安裝的.ipa運行時，Xcode中也幾乎沒有相關信息。這裏是日誌在Xcode：帶有5.2.0 sdk的Titanium ios應用程序在運行或分配模式下啓動時崩潰，但在調試或模擬器中正常工作

我已經通過其他職位，其中一些人指出「使用Javascript縮小」（我關閉，但仍然得到了崩潰）搜查，有的談「最快，最小[-Os]「在Xcode的Build設置的代碼生成部分發布（我不知道如何控制，因爲我使用Appcelerator Titanium來構建應用程序）。其他幾個人討論日誌所揭示的具體代碼問題。由於我沒有在日誌文件中得到任何關於重要性的信息，所以我不確定在哪裏尋找。
任何幫助表示讚賞。
2016年3月21日更新：
我花了一段時間才弄清楚罪魁禍首。以下是重現該問題的步驟：
1）在Titanium Studio中，使用Alloy默認模板創建一個新的Mobile App項目。
2）將新創建的項目原樣運行到USB連接的iPhone 6s Plus（或者可能是任何iOS設備）。
3）點擊設備上的應用程序圖標，該應用程序將在屏幕上用Hello World啓動。
4）現在轉到TiApp.xml文件並通過添加以下參數進行編輯：
<property name="appc-sourcecode-encryption-policy">embed</property>
5）現在將修改的項目運行到USB連接的設備。
6）打開應用程序，你會發現它在啓動屏幕短暫顯示後立即崩潰。
看起來上面的屬性無法正常工作。打開JIRA票AC-3389。
