Building for iOS if registerForRemoteNotificationT

问题:

If there are breaking changes with how devices register for notifications, and we cannot use registerForRemoteNotificationTypes: anymore, how can we build a new version of the app to support iOS 8 if we cannot use Xcode 6 beta? Will we have to build and submit the day the Xcode 6 GM version is released for our users to continue to get push notifications?

回答1:

iOS 8 has changed notification registration. So you need to check device version and then you need to register notification settings.(please check this link.) I try this code on Xcode 6 and its worked for me.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
        if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
        {
            [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
            [[UIApplication sharedApplication] registerForRemoteNotifications];
        }
        else
        {
            [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
             (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
        }

     return YES;
}

You might want to consider using respondsToSelector rather than checking the system version:

if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)]){
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
}
else{
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
#else
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
#endif

回答4:

As per Apple documentation registerForRemoteNotificationTypes: is deprecated in iOS 8 instead you can use registerForRemoteNotifications and registerUserNotificationSettings:.

Xcode 6 beta and iOS 8 beta are pre-release softwar. Beta versions are for development and testing only. New apps and app updates must be built with release versions of Xcode and iOS to submit to the App Store.

if ([[[ UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
{
  [[UIApplication sharedApplication]registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

  [[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
  [[UIApplication sharedApplication] registerForRemoteNotificationTypes(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}

回答6:

You can use this,

if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)]) 
    {
        // for iOS 8
        [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

        [application registerForRemoteNotifications];
    }
    else
    {
        // for iOS < 8
        [application registerForRemoteNotificationTypes:
         (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];
    }

    // RESET THE BADGE COUNT 
    application.applicationIconBadgeNumber = 0;

回答7:

write this code in AppDelegate didFinishLaunchingWithOptions function

 if([[UIApplication sharedApplication] respondsToSelector:@selector(registerForRemoteNotifications)]) {
UIUserNotificationType types = UIUserNotificationTypeAlert | UIUserNotificationTypeSound | UIUserNotificationTypeBadge;
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
[[UIApplication sharedApplication] registerForRemoteNotifications];
 }
        else {
UIRemoteNotificationType types = UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeBadge;
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:types];
  }    [self.window makeKeyAndVisible];
return YES;
