我试图弄清楚为什么我正在开发的应用程序在我的设备上运行时立即开始崩溃（运行 iOS 6.1 的 iPhone 4）。我已经在这个应用程序上工作了大约 8 周，这个问题似乎突然出现了。

当我在模拟器上运行该应用程序时，它运行良好。当我尝试在我的设备上运行它时，它会崩溃，并在以下位置中断：

int main(int argc, char *argv[])
{
    @autoreleasepool {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
    }
}

崩溃发生在 AppDelegate 方法之前

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

被调用。

我查看了设备崩溃日志，但没有看到任何可以让我了解正在发生的事情的线索。有谁知道我可以从哪里开始寻找解决方案？对于它的价值，这里是崩溃日志：

您需要提供更多代码或告诉您的应用程序在启动时会做什么。

But its clear from the crash logs that the Thread0 that main UI thread has been killed. This could be because on device there is a process called watchdog, it kills any processes which seem dubious. like take too much memory or take take too much time to show first screen on app startup & other things which "Apple" thinks would affect user experience. So...

As it turns out there was a problem with my device. I reset my device and the crash disappeared. In future I'll be sure to remember to try resetting my device when I run into this crash.
