registerForRemoteNotificationTypes: is not support

Question

When trying to register for push notifications under iOS 8.x:

application.registerForRemoteNotificationTypes(UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound)

I get the following error:

registerForRemoteNotificationTypes: is not supported in iOS 8.0 and later.

Any ideas what is the new way of doing it? It does work when I run this Swift app on iOS 7.x.

EDIT

On iOS 7.x when I include the conditional code I get (either SystemVersion conditional or #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000)

dyld: Symbol not found: _OBJC_CLASS_$_UIUserNotificationSettings

Answer 1

If you like to add support to IOS7 IOS8 you can apply this code into your project .

-(void) Subscribe {
    NSLog(@"Registering for push notifications...");

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

-(void)application:(UIApplication *)application 
    didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {

    if (notificationSettings.types) {
        NSLog(@"user allowed notifications");
        [[UIApplication sharedApplication] registerForRemoteNotifications];
    } else {
        NSLog(@"user did not allow notifications");
        UIAlertView *alert =[[UIAlertView alloc] 
            initWithTitle:@"Please turn on Notification"
            message:@"Go to Settings > Notifications > App.\n Switch on Sound, Badge & Alert"
            delegate:self
            cancelButtonTitle:@"Ok"
            otherButtonTitles: nil];
        [alert show];
        // show alert here
    }
}

I think this is the better way to keep backwards compatibility if we go with this approach, it is working for my case and hope will work for you. Also pretty easy to understand.

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)];
}

After Xcode 6.1 Beta the code below works, slight edit on Tom S code that stopped working with the 6.1 beta (worked with previous beta):

   if UIApplication.sharedApplication().respondsToSelector("registerUserNotificationSettings:") {
        // It's iOS 8
        var types = UIUserNotificationType.Badge | UIUserNotificationType.Sound | UIUserNotificationType.Alert
       var settings = UIUserNotificationSettings(forTypes: types, categories: nil)
       UIApplication.sharedApplication().registerUserNotificationSettings(settings)
    } else {
        // It's older
        var types = UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound | UIRemoteNotificationType.Alert
        UIApplication.sharedApplication().registerForRemoteNotificationTypes(types)
    }

Answer 4

For the Swift-inclined:

if let registration: AnyObject = NSClassFromString("UIUserNotificationSettings") { // iOS 8+
    let notificationTypes: UIUserNotificationType = (.Alert | .Badge | .Sound)
    let notificationSettings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil)

    application.registerUserNotificationSettings(notificationSettings)
} else { // iOS 7
    application.registerForRemoteNotificationTypes(.Alert | .Badge | .Sound)
}

Answer 5

Swift 2.0

// Checking if app is running iOS 8
    if application.respondsToSelector("isRegisteredForRemoteNotifications") {

        print("registerApplicationForPushNotifications - iOS 8")

        application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil));
        application.registerForRemoteNotifications()

    } else {
        // Register for Push Notifications before iOS 8
        print("registerApplicationForPushNotifications - <iOS 8")
        application.registerForRemoteNotificationTypes([UIRemoteNotificationType.Alert, UIRemoteNotificationType.Badge, UIRemoteNotificationType.Sound])

    }

iOS 8 has changed notification registration in a non-backwards compatible way. While you need to support iOS 7 and 8 (and while apps built with the 8 SDK aren't accepted), you can check for the selectors you need and conditionally call them correctly for the running version.

Here's a category on UIApplication that will hide this logic behind a clean interface for you that will work in both Xcode 5 and Xcode 6.

Header:

//Call these from your application code for both iOS 7 and 8
//put this in the public header
@interface UIApplication (RemoteNotifications)

- (BOOL)pushNotificationsEnabled;
- (void)registerForPushNotifications;

@end

Implementation:

//these declarations are to quiet the compiler when using 7.x SDK
//put this interface in the implementation file of this category, so they are
//not visible to any other code.
@interface NSObject (IOS8)

- (BOOL)isRegisteredForRemoteNotifications;
- (void)registerForRemoteNotifications;

+ (id)settingsForTypes:(NSUInteger)types categories:(NSSet*)categories;
- (void)registerUserNotificationSettings:(id)settings;

@end

@implementation UIApplication (RemoteNotifications)

- (BOOL)pushNotificationsEnabled
{
    if ([self respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
    {
        return [self isRegisteredForRemoteNotifications];
    }
    else
    {
        return ([self enabledRemoteNotificationTypes] & UIRemoteNotificationTypeAlert);
    }
}

- (void)registerForPushNotifications
{
    if ([self respondsToSelector:@selector(registerForRemoteNotifications)])
    {
        [self registerForRemoteNotifications];

        Class uiUserNotificationSettings = NSClassFromString(@"UIUserNotificationSettings");

        //If you want to add other capabilities than just banner alerts, you'll need to grab their declarations from the iOS 8 SDK and define them in the same way.
        NSUInteger UIUserNotificationTypeAlert   = 1 << 2;

        id settings = [uiUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert categories:[NSSet set]];            
        [self registerUserNotificationSettings:settings];

    }
    else
    {
        [self registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert];
    }
}

@end
