didRegisterForRemoteNotificationsWithDeviceToken i

问题:

I have to implement APNS in my project, I have created APNS SSL in developer portal, and using this i have created new provision profile for this. Using SSL certificate I created P12 file then merging it to PEM file. I get popup that App would like to send you notification..... i accept that but still i didn't get the device token !!

In didfinishLaunching i use this part

float ver = [[[UIDevice currentDevice] systemVersion] floatValue];

   if(ver >= 8 && ver<9)
    {
        if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)])
        {
           [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

            [[UIApplication sharedApplication] registerForRemoteNotifications];

            //[[UIApplication sharedApplication] registerUserNotificationSettings:settings];

        }
    }else if (ver >=9){

        [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

        [[UIApplication sharedApplication] registerForRemoteNotifications];

    }
    else{
        //iOS6 and iOS7 specific code
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeAlert];
    }


I have used delegate method of push notification 


- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
{
    NSLog(@"Failed to get token, error: %@", error);
}


- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {

    for (id key in userInfo) {
        NSLog(@"key: %@, value: %@", key, [userInfo objectForKey:key]);
    }    

}

Try with this one.

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0){

    UIUserNotificationType types = UIUserNotificationTypeBadge |
    UIUserNotificationTypeSound | UIUserNotificationTypeAlert;

    UIUserNotificationSettings *mySettings =
    [UIUserNotificationSettings settingsForTypes:types categories:nil];

    [application registerUserNotificationSettings:mySettings];
    [application registerForRemoteNotifications];


}else{
    [application registerForRemoteNotificationTypes:
     (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}

I think you forget your didRegisterUserNotificationSettings method so:

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {
    if (notificationSettings.types != UIUserNotificationTypeNone) {
        NSLog(@"didRegisterUser is called");
        [application registerForRemoteNotifications];
    }
}

at the same place check the following scenario also.

• try in another device once

回答3:

in ios 9 you need to required only if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) { [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]]; [[UIApplication sharedApplication] registerForRemoteNotifications]; }

an other changes is

1. select Project->General set team
2. go capabilities and turn on Push notification.
