objective-c - event - google analytics ios sdk v3

GAIUncaughtExceptionHandler stürzt nur iOS 7 ab (1)

Versucht, einen unserer hartnäckigeren Absturzberichte zu zerquetschen. Verdächtig, da es sich ausschließlich um iOS 7 handelt. * Es ist nicht klar, was der Auslöser ist, und dies ist ein relativ kleiner Prozentsatz unserer Benutzer, die auf das Problem stoßen. Es fühlt sich an wie eine Race Condition oder iOS 7. * spezifischer Fehler mit Google Analytics SDK. Meine Interaktionen mit dem SDK sind einfach:

+ (void)trackEvent:(NSString *)category action:(NSString *)action label:(NSString *)label value:(NSNumber *)value
{
    // May return nil if a tracker has not already been initialized with a
    // property ID.
    id tracker = [[GAI sharedInstance] defaultTracker];

    [tracker send:[[GAIDictionaryBuilder createEventWithCategory:category
                                                          action:action
                                                           label:label
                                                           value:value] build]];
}


+ (void)trackScreenView:(NSString *)screenName
{
    // https://developers.google.com/analytics/devguides/collection/ios/v3/screens

    // May return nil if a tracker has not already been initialized with a
    // property ID.
    id tracker = [[GAI sharedInstance] defaultTracker];

    // This screen name value will remain set on the tracker and sent with
    // hits until it is set to a new value or to nil.
    [tracker set:kGAIScreenName
           value:screenName];

    // Previous V3 SDK versions
    // [tracker send:[[GAIDictionaryBuilder createAppView] build]];

    // New SDK versions
    [self visuallyLogTrackingDetails:tracker dictionaryBuilder:[GAIDictionaryBuilder createScreenView]];
}

Es gibt auch Fälle, in denen ich (zusätzlich zum Anzeigenamen) weitere Daten an den Anruf weitergebe, zB:

+ (void)trackGenderedScreenView:(MyAppGender)gender
{
    id tracker = [[GAI sharedInstance] defaultTracker];

    [tracker set:kGAIScreenName
           value:MyAppAnalyticsGenderedScreenName];

    GAIDictionaryBuilder *dictionaryBuilder = [GAIDictionaryBuilder createScreenView];
    [dictionaryBuilder set:[MyAppUtil getGenderedString:gender]
                    forKey:[GAIFields customDimensionForIndex:ASPAnalyticsDimensionGender]];

    [self visuallyLogTrackingDetails:tracker dictionaryBuilder:dictionaryBuilder];
}

SDK-Version : Google Analytics Services iOS 3.10

Auswirkung : Begrenzt auf iOS 7. *.
