Push notification alert not displaying when coming out of background - ios

Question

Ive got the following code in my app delegate to display the text contained in a Push notification within a UIAlertView.
The code works fine while the app is still loaded in the background, however, once the app goes out of the background, the notification doesn't appear.
Can somebody much cleverer than me show me where I am going wrong, and what I need to do to fix it?
app Delegate.m:
#synthesize pushText;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
[Parse setApplicationId:#"hGG5RdgNVdI7eCeZynV32lWYXywQRHkpp5zLdY7Q"
clientKey:#"TwmNbpBYEt4u3euE3lzNIgwyroSl8RPGF2dJFsPv"];
// Register for Push Notitications, if running iOS 8
if ([application respondsToSelector:#selector(registerUserNotificationSettings:)]) {
UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
UIUserNotificationTypeBadge |
UIUserNotificationTypeSound);
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes
categories:nil];
[application registerUserNotificationSettings:settings];
[application registerForRemoteNotifications];
} else {
// Register for Push Notifications before iOS 8
[application registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge |
UIRemoteNotificationTypeAlert |
UIRemoteNotificationTypeSound)];
}
return YES;
NSMutableArray *alertTextArray = [[NSUserDefaults standardUserDefaults] objectForKey:#"alertTextArray"];
NSDictionary *notifKey = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey];
if (notifKey)
{
[alertTextArray addObject:[notifKey objectForKey:#"alert"]];
}
[[NSUserDefaults standardUserDefaults] setObject:alertTextArray forKey:#"alertTextArray"];
}
- (void)applicationWillResignActive:(UIApplication *)application
{
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}
- (void)applicationDidEnterBackground:(UIApplication *)application
{
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
- (void)applicationWillEnterForeground:(UIApplication *)application
{
// Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
PFInstallation *currentInstallation = [PFInstallation currentInstallation];
if (currentInstallation.badge != 0) {
currentInstallation.badge = 0;
[currentInstallation saveEventually];
}
}
- (void)applicationWillTerminate:(UIApplication *)application
{
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
// Store the deviceToken in the current installation and save it to Parse.
PFInstallation *currentInstallation = [PFInstallation currentInstallation];
[currentInstallation setDeviceTokenFromData:deviceToken];
[currentInstallation saveInBackground];
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
[PFPush handlePush:userInfo];
pushText = [[userInfo objectForKey:#"aps"] objectForKey:#"alert"];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:NSLocalizedString(#"News", "")
message:pushText
delegate:nil
cancelButtonTitle:#"Ok"
otherButtonTitles: nil];
[alert show];
}
#end

Answer 1

Do you mean that when the app is in Foreground (= Running), notifications alert does not show ?
This is actually by design and how iOS notifications work.
If the app is running, notifications alert are not shown and it is up to your app to display them in a way that is meaningful for your application.

Answer 2

You get dictionary with push info when app restarts, it's in launch options, check docs.
