 # Tutorial: Push notifications to iOS apps using Azure Notification Hubs
+
 [!INCLUDE [notification-hubs-selector-get-started](../../includes/notification-hubs-selector-get-started.md)]
 
 In this tutorial, you use Azure Notification Hubs to push notifications to an iOS application. You create a blank iOS app that receives push notifications by using the [Apple Push Notification service (APNs)](https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/APNSOverview.html#//apple_ref/doc/uid/TP40008194-CH8-SW1).

 You have now configured your notification hub with APNS, and you have the connection strings to register your app and send push notifications.
 
 ## Connect your iOS app to Notification Hubs
+
 1. In Xcode, create a new iOS project and select the **Single View Application** template.
-   
+
     ![Xcode - Single View Application][8]
-    
+
 2. When setting the options for your new project, make sure to use the same **Product Name** and **Organization Identifier** that you used when you set the bundle identifier in the Apple Developer portal.
-   
+
     ![Xcode - project options][11]
-    
+
 3. Under Project Navigator, click your project name, click the **General** tab, and find **Signing**. Make sure you select the appropriate Team for your Apple Developer account. XCode should automatically pull down the Provisioning Profile you created previously based on your bundle identifier.
-   
+
     If you don't see the new provisioning profile that you created in Xcode, try refreshing the profiles for your signing identity. Click **Xcode** on the menu bar, click **Preferences**, click the **Account** tab, click the **View Details** button, click your signing identity, and then click the refresh button in the bottom-right corner.

 4. Select the **Capabilities** tab and make sure to enable Push Notifications

 5. Download the [Windows Azure Messaging Framework] and unzip the file. In Xcode, right-click your project and click the **Add Files to** option to add the **WindowsAzureMessaging.framework** folder to your Xcode project. Select **Options** and make sure **Copy items if needed** is selected, and then click **Add**.
 
     ![Unzip Azure SDK][10]
 
 6. Add a new header file to your project named **HubInfo.h**. This file holds the constants for your notification hub. Add the following definitions and replace the string literal placeholders with your *hub name* and the *DefaultListenSharedAccessSignature* noted earlier.
 
-    ```obj-c
-        #ifndef HubInfo_h
-        #define HubInfo_h
-   
-            #define HUBNAME @"<Enter the name of your hub>"
-            #define HUBLISTENACCESS @"<Enter your DefaultListenSharedAccess connection string"
-   
-        #endif /* HubInfo_h */
+    ```objc
+    #ifndef HubInfo_h
+    #define HubInfo_h
+
+        #define HUBNAME @"<Enter the name of your hub>"
+        #define HUBLISTENACCESS @"<Enter your DefaultListenSharedAccess connection string"
+
+    #endif /* HubInfo_h */
     ```
-    
+
 7. Open your **AppDelegate.h** file add the following import directives:
 
-    ```obj-c
-        #import <WindowsAzureMessaging/WindowsAzureMessaging.h>
-        #import <UserNotifications/UserNotifications.h> 
-        #import "HubInfo.h"
+    ```objc
+    #import <WindowsAzureMessaging/WindowsAzureMessaging.h>
+    #import <UserNotifications/UserNotifications.h> 
+    #import "HubInfo.h"
     ```
 8. In your **AppDelegate.m file**, add the following code in the **didFinishLaunchingWithOptions** method based on your version of iOS. This code registers your device handle with APNs:
 
-    ```obj-c
-        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeSound |
-            UIUserNotificationTypeAlert | UIUserNotificationTypeBadge categories:nil];
-   
-        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
-        [[UIApplication sharedApplication] registerForRemoteNotifications];
+    ```objc
+    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeSound |
+        UIUserNotificationTypeAlert | UIUserNotificationTypeBadge categories:nil];
+
+    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
+    [[UIApplication sharedApplication] registerForRemoteNotifications];
     ```
-   
+
 9. In the same file, add the following methods:
 
-    ```obj-c
-         - (void) application:(UIApplication *) application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *) deviceToken {
-           SBNotificationHub* hub = [[SBNotificationHub alloc] initWithConnectionString:HUBLISTENACCESS
-                                        notificationHubPath:HUBNAME];
-   
-            [hub registerNativeWithDeviceToken:deviceToken tags:nil completion:^(NSError* error) {
-               if (error != nil) {
-                   NSLog(@"Error registering for notifications: %@", error);
-                }
-                else {
-                   [self MessageBox:@"Registration Status" message:@"Registered"];
-              }
-          }];
-         }
-   
-        -(void)MessageBox:(NSString *) title message:(NSString *)messageText
-        {
-         UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:messageText delegate:self
-                cancelButtonTitle:@"OK" otherButtonTitles: nil];
-            [alert show];
+    ```objc
+        - (void) application:(UIApplication *) application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *) deviceToken {
+        SBNotificationHub* hub = [[SBNotificationHub alloc] initWithConnectionString:HUBLISTENACCESS
+                                    notificationHubPath:HUBNAME];
+
+        [hub registerNativeWithDeviceToken:deviceToken tags:nil completion:^(NSError* error) {
+            if (error != nil) {
+                NSLog(@"Error registering for notifications: %@", error);
+            }
+            else {
+                [self MessageBox:@"Registration Status" message:@"Registered"];
+            }
+        }];
         }
+
+    -(void)MessageBox:(NSString *) title message:(NSString *)messageText
+    {
+        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:messageText delegate:self
+            cancelButtonTitle:@"OK" otherButtonTitles: nil];
+        [alert show];
+    }
     ```
 
     This code connects to the notification hub using the connection information you specified in HubInfo.h. It then gives the device token to the notification hub so that the notification hub can send notifications.
 
 10. In the same file, add the following method to display a **UIAlert** if the notification is received while the app is active:
 
-    ```obj-c
-            - (void)application:(UIApplication *)application didReceiveRemoteNotification: (NSDictionary *)userInfo {
-               NSLog(@"%@", userInfo);
-               [self MessageBox:@"Notification" message:[[userInfo objectForKey:@"aps"] valueForKey:@"alert"]];
-           }
+    ```objc
+    - (void)application:(UIApplication *)application didReceiveRemoteNotification: (NSDictionary *)userInfo {
+        NSLog(@"%@", userInfo);
+        [self MessageBox:@"Notification" message:[[userInfo objectForKey:@"aps"] valueForKey:@"alert"]];
+    }
     ```
 
 11. To verify there are no failures, build and run the app on your device.
 
 ## Send test push notifications
+
 You can test receiving notifications in your app with the *Test Send* option in the [Azure portal]. It sends a test push notification to your device.

 ## Verify that your app receives push notifications
+
 To test push notifications on iOS, you must deploy the app to a physical iOS device. You cannot send Apple push notifications by using the iOS Simulator.
 
 1. Run the app and verify that registration succeeds, and then press **OK**.
