How to implement push notification for iOS 10[Objective C]?

Can anyone help me with implementing push notification for iOS 10 as i have implemented following code but still getting problem in it:

#define SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)

if(SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(@"10.0"))
{
    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
    center.delegate = self;
    [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error){
        if(!error){
            [[UIApplication sharedApplication] registerForRemoteNotifications];
        }
    }];
}
else {
    // Code for old versions
}

I am getting error suggesting that

Unknown receiver UIUserNotificationCenter

Thank you in advance!

Check this

#import <UserNotifications/UserNotifications.h>

Then

    if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_9_x_Max) {
        UIUserNotificationType allNotificationTypes =
        (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
        UIUserNotificationSettings *settings =
        [UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
        [application registerUserNotificationSettings:settings];
    } else {
        // iOS 10 or later
#if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
        // For iOS 10 display notification (sent via APNS)
        [UNUserNotificationCenter currentNotificationCenter].delegate = self;
        UNAuthorizationOptions authOptions =
        UNAuthorizationOptionAlert
        | UNAuthorizationOptionSound
        | UNAuthorizationOptionBadge;
        [[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:authOptions completionHandler:^(BOOL granted, NSError * _Nullable error) {
        }];
#endif
    }

Sorry guys, I got the answer. I just needed to import UserNotifications framework.

#import <UserNotifications/UserNotifications.h>
