-(void)applicationWillResignActive:(UIApplication *)application
{  
 [[MTraction mTractionManager]applicationWillResignActive];
}

-(void)applicationDidBecomeActive:(UIApplication *)application
{
 [[MTraction mTractionManager]applicationDidBecomeActive];
}

5. Application Push Notifications(Optional)

Follow the below steps to track download conversions:

1. Open your project info.plist available under the Supporting Files section in the Project File Navigator on Xcode.
   Example: If your project name is mTractiontrackertest, then the plist file name shall be, mTractiontrackertest-Info.plist.
2. Add a new key in the Information Property List section of the selected project info.plist info.plist.  

   Key = mt_PushNotification
   Value Type = Boolean
   Value = YES

    
3. Configure Push Notification-
   We need to make a few modification to the app delegate in order to receive push notifications. Include the MTraction.h header file in App delegate To register the current device for push, call the method [application registerForRemoteNotificationTypes:] in the app delegate’s [application:didFinishLaunchingWithOptions:] method.
4.     

   – (BOOL)application:(UIApplication *)application
   didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
   // Register for push notifications
   [self registerUserDeviceForRemoteNotifications];
   return YES;
   }
   
   
   - (void)registerUserDeviceForRemoteNotifications{
       
       
     if([[MTraction mTractionManager] getEnablePushNotification]){
       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)];
       }
     }
   } 

5. Setting up the Device Registration-
   If the registration is successful, the callback method [application:didRegisterForRemoteNotificationsWithDeviceToken:] in the application delegate will be executed. We will need to implement this method and use it to inform mTraction platform about this new device.

6. - (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
   {
     // send device token on mTraction platform
     [[MTraction mTractionManager] setDeviceToken:deviceToken];
   }
   
   
   

7. Setting up the Push Notification Handlers
   Application State : In-Active/Background  
     When a push notification is received while the application is not in the foreground, it is displayed in the iOS Notification Center. When We click on push massage open app and handle by [application:didFinishLaunchingWithOptions:] method.  

8. – (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
   //Remove push msg and badge from Notification center and app
   [[UIApplication sharedApplication] setApplicationIconBadgeNumber:1];
   [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
   //Send Push open msg to mTraction Platform
     [[MTraction mTractionManager] inAppPushNotification:userInfo];
   
   
   }

   Application State : Active/Foreground
    If the notification is received while the app is active, it is up to the app to handle it. To do so, we can implement the [application:didReceiveRemoteNotification] method in the app delegate. Also developer can set custom/own message box in this method.

   (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
   //Remove push msg and badge from Notification center and app
   [[UIApplication sharedApplication] setApplicationIconBadgeNumber:1];
   [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
   //Send Push open msg to mTraction Platform
     [[MTraction mTractionManager] inAppPushNotification:userInfo];
   // Customize your push notification Alert………….
   }

9. Push Notification On/Off Setting from App(Optional)                   
   • Push Notification On Setting:
     Add below line of code in your On UISwitch/UIButton Event Action/Method.

10. [[MTraction mTractionManager] setEnablePushNotification:YES];
    
    
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0){
    //For iOS 8.0 and above
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
    }else{
    //For less iOS than 8.0
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
    (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
    }

    • Push Notification Off Setting:
      Add below line of code in your Off UISwitch/UIButton Event Action/Method.

11. [[MTraction mTractionManager] setEnablePushNotification:NO];
      [[UIApplication sharedApplication] unregisterForRemoteNotifications];
