【问题讨论】：

它说未能及时启动，所以这可能会有所帮助：Application Failed to Launch in Time.

【参考方案1】：

最好的应用程序可以快速启动，允许用户进行交互 尽快申请。为优质用户提供 经验，您应该定期评估并努力改进 应用程序的启动时间。如果必须在 启动，考虑在辅助线程上执行该工作并 直观地指示活动。 http://developer.apple.com/library/ios/#qa/qa1592/_index.html

应用程序启动时间受时间限制。 你一定要看AppDelegate.m 最有可能的是，在- (void)applicationDidFinishLaunching:(UIApplication *)application 方法中，您开始了一些非常长的操作。例如：

AppDelegate.m

- (void)applicationDidFinishLaunching:(UIApplication *)application

  ...
  [[SomeProvider sharedOnlineDataProvider] initializeEngine]; // << this may be very long
  ...

所以，你可以尝试使用

[[SomeProvider sharedOnlineDataProvider] performSelectorInBackground:@selector(initializeEngine) withObject:nil];

显然，initializeEngine 必须是线程安全的

【参考方案2】：

您的应用似乎需要很长时间。当你搜索异常类型时，你会发现：http://developer.apple.com/library/ios/#qa/qa1693/_index.html

您在 AppDelegate didFinishLaunchingWithOptions 中做了很多工作吗？如果是这样，请在后台线程中执行此操作。

【参考方案3】：

我认为您需要将 dSYM 文件链接到崩溃日志并找出导致此崩溃的原因。可以参考this article了解如何使用symbolicatecrash将崩溃日志改回方法调用栈。
