我的应用程序在通过Xcode启动时在3.0设备和3.1设备上运行良好，但在通过iTunes安装时在3.1设备上运行时启动时崩溃。它不会留下任何崩溃日志，但会将其放入控制台：

该应用程序有一个Default.png文件，显示了一会儿，但我认为可能是由SpringBoard / launchd / whatnot加载的，所以我认为这不是我实际上曾经的标志运行
我在同一个盒子上创建了第二个项目，并使用相同的凭据和证书来构建它，并且它可以毫无问题地在iTunes中构建和运行。

我将构建文件作为原始.app文件放在Dropbox上，即使codesign -vvvv AppName.app在Dropbox上我的副本上工作，但它到达时显然已经改变了测试员。认证失败，申请被拒绝启动。
This blog post有助于发现这就是原因，this one有助于发现解决方案（zipping the app使用zip MyApp.zip -r -y MyApp.app）。

尝试通过注释您在加载时运行的代码来隔离问题，并查看您的应用是否至少加载了其主窗口。然后，逐步取消注释代码，并使用NSLog语句记录初始化变量的值（使用调试器使您的问题不会发生，所以我猜NSLog没问题）。如果您发现应用程序因为花费太多时间来预先加载所有内容而崩溃，请尝试通过启动专用后台主机来保持主线程的大量初始化。
