ios - 这次崩溃的可能原因是什么？

Question

我意识到这是一个有点模糊的问题，但我正在寻找一个起点。我正在运行 testflight 并注意到以下崩溃:

从我在 testflight 中了解到的情况来看，崩溃似乎是在打开应用程序时发生的。

这是 applicationDidFinishLaunching 代码:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{   
    NSDictionary *plistData = [[NSBundle mainBundle] infoDictionary];
    MB_LOG_LEVEL = [[plistData valueForKey:@"MBLogLevel"] intValue];

    NSArray *versionParts = [[plistData objectForKey:@"CFBundleVersion"] componentsSeparatedByString:@" "];

    self.versionString = [NSString stringWithFormat:NSLocalizedString(@"version.string", nil),
                          [plistData objectForKey:@"CFBundleShortVersionString"], 
                          // accounts for $Rev: 407 $
                          [versionParts objectAtIndex: ([versionParts count] > 1 ? 1 : 0)],
                          [plistData objectForKey:@"MBBuildDate"]
                          ];

    [self bootstrap];

    // TestFlight and Google Analytics
    [Tracking startup];

    // Add the tab bar controller's current view as a subview of the window
    // Note: Do it this way, since the UIWindow class has no rootViewController
    // property in iOS 3.x.
    [window_ addSubview:self.tabBarController.view];
    [window_ makeKeyWindow];

    // set up APNS with Urban Airship
    [self initAirship:launchOptions];

    // If it is the first time running the app, delete all local notifications
    [self cleanLocalNotifications];

    // Handle launching from a notification
    UILocalNotification *localNotif =
    [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (localNotif) {
        NSLog(@"Recieved Notification %@",localNotif);
    }    

    return YES;
}

这是引导方法:

- (void)bootstrap
{    
    // simple check for a bootstrapped db
    Settings *settings = (Settings*)[DataManager objectForEntity:NSStringFromClass([Settings class]) 
                                            sortDescriptorsOrNil:nil
                                                  predicateOrNil:nil];
    if (!settings) {
        settings = (Settings*)[DataManager createManagedInstance:NSStringFromClass([Settings class])];
        [settings setEnergyMobileFirstRun:[NSNumber numberWithBool:YES]];
        [settings setFirstRun:[NSNumber numberWithBool:YES]];
        [settings setShowWelcomeAlertView:[NSNumber numberWithBool:YES]];
        [settings setOnPeakAlertNotificationTime:[NSNumber numberWithInt:0]];
        [settings setMidPeakAlertNotificationTime:[NSNumber numberWithInt:0]];
        [settings setOffPeakAlertNotificationTime:[NSNumber numberWithInt:0]];
        [settings setOnPeakAlertNotificationsActive:[NSNumber numberWithBool:NO]];
        [settings setMidPeakAlertNotificationsActive:[NSNumber numberWithBool:NO]];
        [settings setOffPeakAlertNotificationsActive:[NSNumber numberWithBool:NO]];
        [DataManager saveManagedInstances];
    }
    if ([settings.firstRun boolValue])
    {
        // Clear the Database
        [DataManager deleteAllObjectsForEntity:@"Appliance"];
        [DataManager deleteAllObjectsForEntity:@"Answer"];
        [DataManager deleteAllObjectsForEntity:@"AnsweredQuestion"];
        [DataManager deleteAllObjectsForEntity:@"Question"];
        [self loadSavingsTipData];
        [self createChecklistTips];
        [self initializeTimeOfUseBehaviour];
        [settings setFirstRun:[NSNumber numberWithBool:NO]];
        [DataManager saveManagedInstances];
    }
}

编辑以添加更多信息:

此堆栈跟踪来自 TestFlight live。崩溃是由从应用商店购买的应用引起的。

Answer 1

我目前仅在 iOS 5.1 设备上的 Production 中看到相同的崩溃。虽然我不确定是什么触发了崩溃，但我认为可以肯定地说这是一个已在 iOS 6 中修复的 Apple 错误。
