检测应用程序在加载/上次运行期间崩溃了吗？ [英] Detect app crashed during load / last time it was run?

问题描述

如果我的应用在启动过程中崩溃，我希望将其重置为标准设置。 最好也是如果它在上次运行时崩溃。

I would like for my app to reset to standard settings if it crashed during startup. Preferably also if it crashed last time it was run.

编辑： Crittercism 有一个 crittercismDidCrashOnLastLoad 方法，但它只处理加载期间崩溃的情况。它在我使用的库版本中无法正常工作，但此后已修复。

Crittercism has a crittercismDidCrashOnLastLoad method, but it only handles the case of crashing during load. It didn't work properly in the version of the library I used, but this has since been fixed.

建议？

推荐答案

在 AppDelegate.m 文件中创建2个函数：

Make 2 functions in your AppDelegate.m file:

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）应用程序中：didFinishLaunchingWithOptions 之前放入任何其他内容：

Then in your -(BOOL)application:didFinishLaunchingWithOptions before anything else put:

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);
