Llamar a didReceiveRemoteNotification cuando la aplicación se inicia por primera vez

Question

Implementé mi método didReceiveRemoteNotification. Funciona y muestra un controlador de vista con los datos de notificación que se pasan. Esto solo funciona cuando la aplicación ya estaba en primer plano o si se estaba ejecutando en segundo plano. Sin embargo, cuando la aplicación no se está ejecutando y el usuario hace clic en una notificación, la aplicación se inicia, pero parece que no se recibió ninguna notificación. La notificación no está escrita en el archivo de texto y no se está presionando el controlador de vista.

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    if ( application.applicationState == UIApplicationStateActive)
    {
        NSDictionary *apsInfo = [userInfo objectForKey:@"aps"];

        NSString *alertMsg = @"";
        NSString *badge = @"";
        NSString *sound = @"";
        NSString *custom = @"";

        if( [apsInfo objectForKey:@"alert"] != NULL)
        {
            alertMsg = [apsInfo objectForKey:@"alert"];
        }


        if( [apsInfo objectForKey:@"badge"] != NULL)
        {
            badge = [apsInfo objectForKey:@"badge"];
        }


        if( [apsInfo objectForKey:@"sound"] != NULL)
        {
            sound = [apsInfo objectForKey:@"sound"];
        }

        if( [userInfo objectForKey:@"Type"] != NULL)
        {
            custom = [userInfo objectForKey:@"Type"];
        }

        // Set your appending text.
        NSString *textToAdd = [NSString stringWithFormat:@":%@", alertMsg];

        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = [paths objectAtIndex:0];

        NSString *fileContents = [[NSString alloc]  initWithContentsOfFile:fileName usedEncoding:nil error:nil];

        NSString *textToFile;

        if (fileContents == NULL)
        {
            textToFile = alertMsg;

        [content writeToFile:fileName atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil];

        NSArray *fileData = [textToFile componentsSeparatedByString:@":"];

        NSMutableArray *tableDataFromFile;
        tableDataFromFile = [[NSMutableArray alloc] init];

        int i = 0;

        for (i = 1; i < [fileData count]; i++)

}

¿Podría alguien ayudarme a resolver este problema? El booleano done se establece en verdadero una vez que se completa didFinishLaunchingWithOptions. Solo quiero que el controlador de vista de notificaciones se abra y muestre la notificación si se presiona una notificación mientras la aplicación no se está ejecutando.

Answer 1

Debe agregar algo como esto a su código:

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary
    *)launchOptions {

        NSDictionary *remoteNotif = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey];

        //Accept push notification when app is not open
        if (remoteNotif) {      
            [self handleRemoteNotification:application userInfo:remoteNotif];
            return YES;
        }

        return YES;
    }

Puede mover la lógica de didReceiveRemoteNotification a alguna función común y llamar a esa función desde ambos lugares. Esto solo funcionará si el usuario abre la aplicación tocando la notificación. Si el usuario abre la aplicación tocando el ícono de la aplicación, los datos de notificación no llegarán a la aplicación.

Answer 2

código SWIFT

let remoteNotif: AnyObject? = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey]

            //Accept push notification when app is not open
            if ((remoteNotif) != nil) {

                self.handleRemoteNotification(remoteNotif!)
            }


func handleRemoteNotification(remoteNotif: AnyObject?){
//handle your notification here
}

@Eran gracias :)
