ios - 检测应用程序在加载期间崩溃/上次运行时崩溃？

Question

如果我的应用程序在启动期间崩溃，我希望它能够重置为标准设置。 如果它上次运行时崩溃也是最好的。

编辑:Crittercism 有一个 crittercismDidCrashOnLastLoad 方法，但它只处理加载过程中崩溃的情况。它在我使用的库版本中无法正常工作，但此问题已得到修复。

建议？

Answer 1

在您的 AppDelegate.m 文件中制作 2 个函数:

void HandleException(NSException *exception) {
    NSLog(@"App crashing with exception: %@", exception);
    //Save somewhere that your app has crashed.
}

void HandleSignal(int signal) {
    NSLog(@"We received a signal: %d", signal);
    //Save somewhere that your app has crashed.
}

然后在你的 -(BOOL)application:didFinishLaunchingWithOptions 之前放任何东西:

NSSetUncaughtExceptionHandler(&HandleException);

struct sigaction signalAction;
memset(&signalAction, 0, sizeof(signalAction));
signalAction.sa_handler = &HandleSignal;

sigaction(SIGABRT, &signalAction, NULL);
sigaction(SIGILL, &signalAction, NULL);
sigaction(SIGBUS, &signalAction, NULL);
