Get device token for push notification

I am working on push notifications. I wrote the following code for fetching a device token.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
    // Override point for customization after application launch.

    // Add the view controller's view to the window and display.
    [self.window addSubview:viewController.view];
    [self.window makeKeyAndVisible];

    NSLog(@"Registering for push notifications...");    
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     (UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

    return YES;
}

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { 
    NSString *str = [NSString stringWithFormat:@"Device Token=%@",deviceToken];
    NSLog(@"This is device token%@", deviceToken);
}

- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err { 
    NSString *str = [NSString stringWithFormat: @"Error: %@", err];
    NSLog(@"Error %@",err);    
}

I am able to run application on device successfully but not able to get the device id on console.

I have no issues with certification and provisioning profiles.

You have to use following code to get device token:-

Objective-C

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken 
{
    NSString *token = [[deviceToken description] stringByTrimmingCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@"<>"]];
    token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
    NSLog(@"content---%@", token);
} 

Swift 3.0

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
{
    let   tokenString = deviceToken.reduce("", {$0 + String(format: "%02X",    $1)})
    // kDeviceToken=tokenString
    print("deviceToken: (tokenString)")
}

To get Token Device you can do by some steps :

1) Enable APNS (Apple Push Notification Service) for both Developer Certification and Distribute Certification, then redownload those two file.

2) Redownload both Developer Provisioning and Distribute Provisioning file.

3) In Xcode interface: setting provisioning for PROJECT and TARGETS with two file provisioning have download.

4) Finally, you need to add the code below in AppDelegate file to get Token Device (note: run app in real device).

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
     [self.window addSubview:viewController.view];
     [self.window makeKeyAndVisible];

     NSLog(@"Registering for push notifications...");    
     [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
 (UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
     return YES;
}

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { 
     NSString *str = [NSString stringWithFormat:@"Device Token=%@",deviceToken];
     NSLog(@"%@", str);
}

- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err { 
     NSString *str = [NSString stringWithFormat: @"Error: %@", err];
     NSLog(@"%@",str);
}

以下代码用于检索设备令牌。

    // Prepare the Device Token for Registration (remove spaces and < >)
    NSString *devToken = [[[[deviceToken description] 
                            stringByReplacingOccurrencesOfString:@"<"withString:@""] 
                           stringByReplacingOccurrencesOfString:@">" withString:@""] 
                          stringByReplacingOccurrencesOfString: @" " withString: @""];


    NSString *str = [NSString 
                     stringWithFormat:@"Device Token=%@",devToken];
    UIAlertView *alertCtr = [[[UIAlertView alloc] initWithTitle:@"Token is " message:devToken delegate:self cancelButtonTitle:nil otherButtonTitles: nil] autorelease];
    [alertCtr show];
    NSLog(@"device token - %@",str);
