# \*App Delegate

Objective-c

```
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [[RPPermissionsWizard returnInstance] launchWithFinish:^(BOOL showWizzard) {
        [RPEntry initializeWithRequestingPermissions:YES]; // Yes, if you don’t want to implement requesting by yourself

        [RPEntry instance].disableTracking = NO;
        [RPEntry application:application didFinishLaunchingWithOptions:launchOptions];
    }];
}
```

Swift: 

```
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    RPPermissionsWizard.returnInstance().launch(finish: { _ in
        RPEntry.initialize(withRequestingPermissions: true)
        let token = NSString(string: "Please, enter your Token")
        RPEntry.instance().virtualDeviceToken = token
        let options = launchOptions ?? [:]
        RPEntry.application(application, didFinishLaunchingWithOptions: options)
    })
    return true
}
```

**Implement AppDelegate methods**

Objective-c:

```
- (void)application:(UIApplication *)application handleEventsForBackgroundURLSession:(nonnull NSString *)identifier completionHandler:(nonnull void (^)(void))completionHandler {
    [RPEntry application:application handleEventsForBackgroundURLSession:identifier completionHandler:completionHandler];
}

- (void)applicationDidReceiveMemoryWarning:(UIApplication *)application {
    [RPEntry applicationDidReceiveMemoryWarning:application];
}

- (void)applicationWillTerminate:(UIApplication *)application {
    [RPEntry applicationWillTerminate:application];
}

- (void)applicationDidEnterBackground:(UIApplication *)application {
    [RPEntry applicationDidEnterBackground:application];
}

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

- (void)application:(UIApplication *)application performFetchWithCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
    [RPEntry application:application performFetchWithCompletionHandler:^{
        completionHandler(UIBackgroundFetchResultNewData);
    }];
}
```

Swift:

```
func application(_ application: UIApplication, handleEventsForBackgroundURLSession identifier: String, completionHandler: @escaping () -> Void) {
    RPEntry.application(application, handleEventsForBackgroundURLSession: identifier, completionHandler: completionHandler)
}

func applicationDidReceiveMemoryWarning(_ application: UIApplication) {        RPEntry.applicationDidReceiveMemoryWarning(application)
}

func applicationWillTerminate(_ application: UIApplication) {
    RPEntry.applicationWillTerminate(application)
}

func applicationDidEnterBackground(_ application: UIApplication) {
    RPEntry.applicationDidEnterBackground(application)
}

func applicationDidBecomeActive(_ application: UIApplication) {
    RPEntry.applicationDidBecomeActive(application)
}

func application(_ application: UIApplication, performFetchWithCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    RPEntry.application(application) {
        completionHandler(.newData)
    }
}
```
