Push Notification -didFinishLaunchingWithOptions
Swift 2.0 For 'Not Running' State (Local & Remote Notification)
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Handle notification
if (launchOptions != nil) {
// For local Notification
if let localNotificationInfo = launchOptions?[UIApplicationLaunchOptionsLocalNotificationKey] as? UILocalNotification {
if let something = localNotificationInfo.userInfo!["yourKey"] as? String {
self.window!.rootViewController = UINavigationController(rootViewController: YourController(yourMember: something))
}
} else
// For remote Notification
if let remoteNotification = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as! [NSObject : AnyObject]? {
if let something = remoteNotification["yourKey"] as? String {
self.window!.rootViewController = UINavigationController(rootViewController: YourController(yourMember: something))
}
}
}
return true
}
Swift 5
To get push notification Dictionary in didFinishLaunchingWithOptions when app is kill and push notification receive and user click on that
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
if let userInfo = launchOptions?[UIApplication.LaunchOptionsKey.remoteNotification] as? [String: AnyObject] {
if let aps1 = userInfo["aps"] as? NSDictionary {
print(aps1)
}
}
return true
}
Push notification Dictionary will display in alert.
Since you only want to present a viewController
when you get a Push Notification, you may try utilizing NSNotificationCenter
for your purposes:
Part 1: Set up a class (in your case, the rootViewController
) to listen/respond to a NSNotification
Suppose, MainMenuViewController
is the rootViewController
of your navigationController
.
Set up this class to listen to a NSNotification
:
- (void)viewDidLoad {
//...
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(presentMyViewOnPushNotification)
name:@"HAS_PUSH_NOTIFICATION"
object:nil];
}
-(void)presentMyViewOnPushNotification {
//The following code is no longer in AppDelegate
//it should be in the rootViewController class (or wherever you want)
UIStoryboard *mainstoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
PushMessagesVc *pvc = [mainstoryboard instantiateViewControllerWithIdentifier:@"PushMessagesVc"];
[self presentViewController:pvc animated:YES completion:nil];
//either presentViewController (above) or pushViewController (below)
//[self.navigationController pushViewController:pvc animated:YES];
}
Part 2: Post Notification (possible from anywhere in your code)
In your case, AppDelegate.m methods should look like:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//firstly, don't sleep the thread, it's pointless
//sleep(1); //remove this line
if (launchOptions) { //launchOptions is not nil
NSDictionary *userInfo = [launchOptions valueForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
NSDictionary *apsInfo = [userInfo objectForKey:@"aps"];
if (apsInfo) { //apsInfo is not nil
[self performSelector:@selector(postNotificationToPresentPushMessagesVC)
withObject:nil
afterDelay:1];
}
}
return YES;
}
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
//this method can be done using the notification as well
[self postNotificationToPresentPushMessagesVC];
}
-(void)postNotificationToPresentPushMessagesVC {
[[NSNotificationCenter defaultCenter] postNotificationName:@"HAS_PUSH_NOTIFICATION" object:nil];
}
PS: I haven't done this for my projects (yet) but it works and is the best way i could think of doing this kinda stuff (for the moment)
