Hey I'm new to iPhone and I have been trying to use an Apple push notification. Basically, what I want to do is that when user clicks on the received push notification message, then i need to open a specific view controller. I have added custom data with key parameter "type" to my payload JSON, so on behalf of notification type value i need to open particular view controller instead of the main view controller.
here is my payload JSON :
{"aps":{"alert":"This is testing message","type":"Notify","badge":1,"sound":"default"}}
my code is :
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
splashViewController = [[SplashViewController alloc] initWithNibName:#"SplashViewController" bundle:nil];
self.window.rootViewController = splashViewController;
[self.window makeKeyAndVisible];
return YES;
}
- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo
{
//this will call when your app will get any notification from server.
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
NSDictionary *aps = (NSDictionary *)[userInfo objectForKey:#"aps"];
NSMutableString *notificationType = [aps objectForKey:#"type"];
NSLog(#"notification type is = %#", notificationType);
//For redirect to the view
UIViewController *viewController;
if([notificationType isEqualToString:#"Notify"]){
//Notify updates
UpdatesViewController *uvc1 = [[UpdatesViewController alloc] initWithNibName:#"UpdatesViewController" bundle:nil];
viewController = uvc1;
}
else {
//Voting & QA
VotingViewController *votingViewController = [[VotingViewController alloc] initWithNibName:#"VotingViewController" bundle:nil];
viewController = votingViewController;
}
[self.window.rootViewController presentViewController:viewController animated:YES completion:NULL];
}
My code is not presenting other view controller. As mentioned in my code, i am getting two kind of web service (notification type) 1. Notify and 2. Voting from Apple. i dont know how to present specific view controller on behalf of notification type, if type is "notify" then i need open UpdatesViewController else it will open other viewcontroller. If anyone knows how to do this, please help me.
Thanks.
//For redirect to the view
UIViewController *uvc;
if([notificationType isEqualToString:#"Notify"]){
UIViewController *updates = [[UpdatesViewController alloc] initWithNibName:#"UpdatesViewController" bundle:nil];
// add updates specific data updates.data = [aps objectForKey:#"data"];
uvc = updates;
}
else if([notificationType isEqualToString:#"Voting "]) {
UIViewController *voting = [[VotingViewController alloc] initWithNibName:#"VotingViewController" bundle:nil];
// add voting specific data voting.data = [aps objectForKey:#"data"];
uvc = voting;
}
[self.window.rootViewController presentViewController:uvc animated:YES completion:NULL];
you should check the aps in didFinishLaunchingWithOptions.
didReceiveRemoteNotification only works when app is running or suspended.

SO I am creating an iOS app that involves allowing the user to be able to receive push notifications. I already have the following code in my appDelegate didFinishLaunchingWithOptions.
if ([application respondsToSelector:#selector(isRegisteredForRemoteNotifications)])
{
// iOS 8 Notifications
[application registerUserNotificationSettings: [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
[application registerForRemoteNotifications];
}
So far so good, however, i would like to create an initial view controller that only shows on first launch, it will hopefully explain and justify to the user why it need the ability to send the user push notifications, they can then press continue and it will ask them by executing the code above. This would hopefully only happen on the first launch. Any suggestions?
Thanks
I think you can do something like this
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.backgroundColor = [UIColor whiteColor];
BOOL userHasOnboarded = [[NSUserDefaults standardUserDefaults] boolForKey:#"isFirstTime"];
if (userHasOnboarded) {
[self setupNormalRootViewControllerAnimated:YES];
}
else {
self.window.rootViewController = [self PushExplanation];
}
[self.window makeKeyAndVisible];
return YES;
}
- (void)setupNormalRootViewControllerAnimated:(BOOL)animated {
UIViewController *mainVC = [UIViewController new];
mainVC.title = #"Home View Controller";
if (animated) {
[UIView transitionWithView:self.window duration:0.5 options:UIViewAnimationOptionTransitionCrossDissolve animations:^{
self.window.rootViewController = [[UINavigationController alloc] initWithRootViewController:mainVC];
} completion:nil];
}
else {
self.window.rootViewController = [[UINavigationController alloc] initWithRootViewController:mainVC];
}
}
In your PushExplanation method you can show the UIviewController you want to show once and then in the same UIViewController you can ask for Push Notifications like this
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
Hope this help you
This is trivial.
Add a boolean flag haveDisplayedFirstVC to NSUserDefaults. Read it at startup. If it's false, you need to display your first time VC.
In that case, if you're using storyboards, use instantiateViewControllerWithIdentifier: to load a view controller from your storyboard. If you're using nibs, use initWithNibName:bundle:
Once you've created and configured the view controller, display it on top of your standard interface's VC using `presentViewController:animated:completion:' but with animated = NO. That way it will appear on top of your normal interface as the app starts up. (Or animate it onto the screen, whichever you prefer.)
Add the status (Bool) in NSUserDefault and Firsttime check if the key is there or not .
If there is no value,then display your initial viewcontroller and change the status to yes(probably).
Next time normal page will load.

My question is: Is this the correct way to redirect to the view controller when push notification is received?
Using the above code, it is redirecting to the view controller class on behalf on Notification type (custom key of notification payload json) successfully in forground and background mode but that redirected View Controller back button is not working. I don't know where i am doing wrong here. If anyone knows then please help me. Thanks.
Better You can post the notification using NSNotificationCentre in didReceiveRemoteNotification and receive the notification on the other classes. So that you can push the required view controller from the current view controller (need not to set as root view controller). Then the back button will works.
For Ex.
[[NSNotificationCenter defaultCenter] postNotificationName:kMesssagePushNotification object:nil userInfo:userInfo];
The back button is not working, because you are setting the target view as a root view. You should instead construct the full navigation stack, i.e. usually, if you have a navigation view controller as a root view controller, you should create that first and then construct all the view controllers that are between the root and your leaf view.
For example, if MainViewController would be your normal start view and the back button from UpdatesViewController should lead to MainViewController you would do:
MainViewController *mainVC = [[MainViewController alloc] initWithNibName:#"MainViewController" bundle:nil];
UpdatesViewController *updatesVC = [[UpdatesViewController alloc] initWithNibName:#"UpdatesViewController" bundle:nil];
UINavigationController *navVC=[[UINavigationController alloc]initWithRootViewController:mainVC];
[navVC setViewControllers:#[mainVC, updatesVC] animated:NO];
self.window.rootViewController = navVC;
There are two chances that you will access the notification data.
If you receive the notification when your app isn't on, then click the notification and you will get the notification data in the following function:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
use
launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]
to access the notification data and open the view controller you expected.
If you receive the notification when your app is on, but your app can be in background or foreground. If it is the former case, you will receive the notification in notification center, your app will invoke the following function after you click the notification:
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
If it is the later case, you app will directly invoke the function before. And you can distinguish them using the flowing code:
UIApplicationState state = [[UIApplication sharedApplication] applicationState];
if (state == UIApplicationStateBackground || state == UIApplicationStateInactive){
//notification is received when your app is in background
//open the view controller you expected
}else if(state == UIApplicationStateActive){
//notification is received when your app is in foreground
//do nothing
}
sorry for my pool English, hope it helps~
My app has an embedded navigation controller. I want to launch a particular viewController that is not the initial view or rootViewController.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions
{
NSDictionary *dictionary = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (dictionary != nil)
{
UIViewController *rootController = (UIViewController *)self.window.rootViewController;
UIViewController *notificationController = [rootController.storyboard instantiateViewControllerWithIdentifier:#"NotificationsViewController"];
[rootController presentViewController:notificationController animated:NO completion:^{
}];
}
}
I know I have to input the code in here but am not sure how exactly I can code it. Can someone help? I get the error code:
Warning: Attempt to present <NotificationsViewController: 0x176883a0> on <SWRevealViewController: 0x17683750> whose view is not in the window hierarchy!
SWRevealViewController is my library for my sidebar view. My guess is that my "root" isn't what I think it is.
If I want to set viewControllerX as my root view, how can I accomplish this?
You should initialize your rootViewController first.
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
YourViewControllerX * viewControllerX = [[YourViewControllerX alloc] init];
self.window.rootViewController = viewControllerX;
[self.window makeKeyAndVisible];
try
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions{
[self.window addSubview:self.window.rootViewController.view];
[self.window makeKeyAndVisible];
NSDictionary *dictionary = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (dictionary != nil){
...
}
}
In order to show my login screen when the app loads, and not after the user logs in, I have decided to add an auth object in NSUserDefaults when the user logs in successfully. When the app is launched that auth parameter is checked, and the view controller is set accordingly (if the user is auth it'll show a feed, if not it'll show a login screen) In the latter case, I have the app delegate reset the root view controller to the feed after the user has logged in. Is this bad practice or is there a better way of doing this?
In the app delegate:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
IIViewDeckController* deckController = [self generateControllerStack];
self.rightController = deckController.rightController;
self.centerController = deckController.centerController;
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
if([[defaults objectForKey:#"auth"] isEqualToNumber:[NSNumber numberWithInt:1]]){
self.window.rootViewController = deckController;
}else{
UIStoryboard *sb = [UIStoryboard storyboardWithName:#"MainStoryboard"
bundle:nil];
UIViewController* vc = [sb instantiateViewControllerWithIdentifier:#"loginViewController"];
self.window.rootViewController = vc;
}
[self.window makeKeyAndVisible];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque animated:NO];
return YES;
}
- (void) setRoots
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
IIViewDeckController* deckController = [self generateControllerStack];
self.rightController = deckController.rightController;
self.centerController = deckController.centerController;
self.window.rootViewController = deckController;
[self.window makeKeyAndVisible];
}
In the login view controller:
- (IBAction)loginClick:(id)sender {
if([_emailField.text length]>0&&[_passField.text length]>0){
NSString *user = _emailField.text;
NSString *pass = _passField.text;
[[API sharedInstance] login:user andPass:pass onCompletion:^(NSDictionary *json){
NSLog(#"%#", json);
if(![json objectForKey:#"error"]){
[API sharedInstance].authorized = 1;
NSNumber *auth = [NSNumber numberWithInt:1];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:auth forKey:#"auth"];
[defaults synchronize];
captureYouAppDelegate *app = [[UIApplication sharedApplication] delegate];
[app setRoots];
}else{
[API sharedInstance].authorized = 0;
}
}];
}else{
if([_emailField.text length]<1){
[_emailField becomeFirstResponder];
}else{
[_passField becomeFirstResponder];
}
}
}
I'm wondering if there is a better or easier way than doing that. Thank you!
Just to clarify. I had reset UIWindow's rootViewController before without any problem but when attempting to do so while allowing device rotation I ran into some issues — Rotation just stopped working.
I found the following directly from Apple's docs while trying to debug. The link below has a number of guidelines about working with UIWindow. These are all related to device rotation but still good to know.
Short answer, use a root controller and add child view controllers. You can then swap out the child VCs with no problem.
• You have added your view controller's UIView property to UIWindow as a subview.
Developers are discouraged from adding the view property of any view controller as a subview of UIWindow. Your application's root view controller should be assigned to the app window's rootViewController property either in Interface Builder, or at runtime before returning from application:didFinishLaunchingWithOptions:. If you need to display content from more than one view controller simultaneously, you should define your own container view controller and use it as the root view controller. See Creating Custom Container View Controllers.
Check this technical Q&A for more details.
I don't think reset the window.rootViewController is a bad practice. However, there is no need to recreate a window.
If you don't want to use the previous view controller, just replace the window's rootViewController with the new view controller. If you do want to switch back to your previous view controller, use -presentViewController: animated: completion: to present your view controller may be a better alternative.
There is no need to alloc window again you can directly set this
window.rootViewController = yourVC;

I'm writing an iOS application which I need to have the user login to. The login will need to make a JSON request to a web service, then store the user details in Core Data or wherever is best.
Further, I need to have the login modal appear before the main application kicks in, I know that for this I call it in - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions.
So, I need a simple login, username and password field, make a request and then store the resulting JSON data into somewhere, core data perhaps?
I've searched high and low for a login example, but they're all very rudimentary or not doing quite what I want. I'm thinking of creating a xib file then calling that, but I'm unsure about it all.
I was wondering the same question several days ago.
Here is my solution:
in didFinishLaunchingWithOptions ,I invoke a method check whether there is account and password in your database(core data? i just use the userdefault).
If there is , try login, if login fail, present a modal view. if successed, set your appdelegate.window.rootviewcontroller the main viewcontroller
If there is nothing, show modal view.
or login failed, blablabla...
sorry for my poor English.
here is my code:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[AFNetworkActivityIndicatorManager sharedManager] setEnabled:YES];
UINavigationController *nav = [[UINavigationController alloc] init];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.window.backgroundColor = [UIColor whiteColor];
self.window.rootViewController = nav;
[self.window makeKeyAndVisible];
[ZTCAPIClient registerUserInfo];
return YES;
}
+ (void) registerUserInfo {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *account = [defaults stringForKey:#"account"];
if(!account) {

//DLog(#"Log in FAIL");
dispatch_async(dispatch_get_main_queue(), ^{
ZTCUserSettingsViewController *userSettingsView = [[ZTCUserSettingsViewController alloc] init];
UINavigationController *usersSettingsNav = [[UINavigationController alloc] initWithRootViewController:userSettingsView];

[ZTCNotice showErrorNoticeInView:userSettingsView.view title:NSLocalizedString(#"login fail title", nil) message:NSLocalizedString(#"login fail message", nil)];
});
}
});
}
}
Just make didFinishLaunchingWithOptions modally push your LoginViewController to the navigation stack. If you're using a storyboard, you can just make your LoginViewController the root view controller, or alternatively place a segue, give it an identifier, and just call [rootViewController performSegueWithIdentifier:#"YourSegueId" sender:self].
