I'm having trouble enabling push notifications.
with this code I try to enable the notification:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationType)(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
return YES;
}
It doesnt work, so I added a breakpoint in the line
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationType)(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
But it seems this part of the code is never execute.
why is this not working?
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
This should be implemented in your UIApplicationDelegate, not in your UIViewController. If you have it in your UIViewController, it will never get called. Take the code out of there and put it in your UIApplicationDelegate instead.

I do not know how to replace "method" with the following app delegate method.
viewcontroller
[(AppDelegate *)[[UIApplication sharedApplication] delegate] method];
appdelegate
- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)devToken {
TUPushHelper * helper = [[TUPushHelper alloc] initWithTokenData:devToken];
[helper registerDevice];
}
You do not need to call it programmatically. The delegate receives this message after the registerForRemoteNotificationTypes: method of UIApplication is invoked and there is no error in the registration process. didFailToRegisterForRemoteNotificationsWithError: will be called otherwise.
To register your device for remote push notifications you have to do this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
...
}

I am sending a local notification once a process is finished and it acts just fine.
This is my code for didReceiveLocalNotification:
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{
CounterViewController *counterVC = [CounterViewController sharedInstance];
[counterVC notificationArrived];
}
But when the iPhone is locked those lines aren't called… What can I do to make them run in the background?
There are two method to receive local notification one is already you have implemented which is invoked while app is running & 2nd is in didFinishLaunchingWithOptions which is invoked while your app is running background you have add some code for receive local notification .....
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
// Add the view controller's view to the window and display.
application.applicationIconBadgeNumber = 0;
// Handle launching from a notification
UILocalNotification *localNotif =
[launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (localNotif) {
NSLog(#"Recieved Notification %#",localNotif);
}
return YES;
}
I would like to enable notifications in my iphone app. So, I modify in app ID:
After that, I generate again Development and Distribution Provisioning Profiles and installed in my xcode.
My app is a tabbed based application, the first tab is UITableViewController
I add this lines:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
return YES;
}
So, I suppose I should have my app in the list of app installed with notifications in my iphone, but it isnt.
Did I miss some step?
Yep. According to this and this you should add the registerForRemoteNotificationTypes method in your didFinishLaunchingWithOptions, which should the look something like this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
return YES;
}
Depending on which Types you registered your app will appear in the notifications section and you can turn on and off the different types (sound, badge, banner).
Hope that helps.
First enable your remote notification in app delegate. See below :
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
// Let the device know we want to receive push notifications
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
return YES;
}
I followed http://iosdevelopertips.com/cocoa/launching-your-own-application-via-a-custom-url-scheme.html instruction to open app1(GlassButton) within app2(FontTest).
The open method of FontTest as following:
-(void)open {
BOOL res = [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:#"glassbutton://"]];
if (res) {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:#"glassbutton://"]];
}
}
The value of "res" is "YES", but nothing happen after openURL method be called.
The info-list of "FontTest"as following:
URL Schemes: glassbutton
URL identifier: com.yourcompany.glassbutton
I tried to open twitter and facebook apps by "twitter://" and "fb://" successfully. But I do not know why I cannot open this small app. I'm not sure whether any thing/step wrong or missing? Need I handle - (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url for FontTest, if yes, how to handle it? Could you please kindly help me? Thanks in advance!
To request the launch of your app use something like this:
NSString *urlString= #"glassbutton://com.yourcompany.glassbutton";
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];
Then, in the glassbutton app, you'll need to handle any special behavior within the app delegate method:
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
//your app specific code here for handling the launch
return YES;
}
Note that within the app you are opening the above delegate method will only get called AFTER the following method is called:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
Handle accordingly, good luck.
i have load the mailcomposer on reciving the localnotification
is it possible??
You should code as follows,
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (localNotif)
{
//code for opening mail composer
}
-(void) application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
//code for opening mail composer
}
