iOS push notification message - action after clicking VIEW button

Question

i have some problems with the Push Notifications. I can sent them well to my registered Devices. All works fine.

My Questions is: After clicking the VIEW button, the App is launching. At the moment without any content.

How can i add content here? This content should depend on the Push Notification i sent out.

For example: My Push Notification is about NEWS Number 1 - then after clicking VIEW i should get more informations about NEWS Number 1

and so on...

Also it should be possible to read all previous received NEWS in the App in a list, when getting back from NEWS Number 1.

You understand, what i mean?

I dont have any real idea...Would be nice if you can show me code regarding to an example.

Thanks.

Answer 1

Just implement the following code and you are good to go:

// will be called if the app was not active
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [self applicationDidFinishLaunching:application];

    if (launchOptions != nil)
    {
        NSDictionary* dictionary = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
        if (dictionary != nil)
        {
            // get the necessary information out of the dictionary 
            // (the data you sent with your push message)
            // and load your data
        }
    }
    return YES;
}

// will be called when in foreground
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {    
    // get the necessary information out of the dictionary 
    // (the data you sent with your push message)
    // and load your data
  }
