Urban Airship Crashes in 2.0

问题

I keep getting this error

-----l- networkStatusForFlags

This is my code:

//Add onto main thread queue to excute asyncrously and to prevent Urban Airship Crashing
dispatch_async(dispatch_get_main_queue(), ^{
    //Load Urban Airship
    DLog(@"Loading Urban Airship...");

    // Disable Push
    [[UAPush shared] setPushEnabled:NO];

    // Populate AirshipConfig.plist with your app's info from https://go.urbanairship.com
    // or set runtime properties here.
    UAConfig *config = [UAConfig defaultConfig];

    config.developmentAppKey = UADevelopmentKey;
    config.developmentAppSecret = UADevelopmentSecret;
    config.productionAppKey = UAProductionKey;
    config.productionAppSecret = UAProductionSecret;
    config.detectProvisioningMode = YES;

    #ifdef DEBUG
    config.clearKeychain = YES;
    #endif

    // Call takeOff (which creates the UAirship singleton)
    [UAirship takeOff:config];

    DLog(@"Finished Loading Urban Airship");
});

回答1:

This could happen if you had any of the urban airship code running before a call to

    [UAirship takeOff:config];

I placed my code after this statement and the crash went away.
