iOS App not registering for push notifications - ios8

Question

I am trying to register for push notifications in my iOS app. But it is calling neither the didRegisterForRemoteNotificationsWithDeviceToken nor didFailToRegisterForRemoteNotificationsWithError callback methods. I have revoked and regenerated the provisioning profile for the app.
I am using iOS8 and I have enabled the following background modes in my Info.plist
App registers for location updates
App downloads content in response to push notifications
App downloads content from the network
The code is:
-(void) application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
NSLog(#"Failed to register for push");
}
-(void) application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
NSLog(#"did succeed in register for push");
// Get the device token string
const char* data = [deviceToken bytes];
NSMutableString* token = [NSMutableString string];
for (int i = 0; i < [deviceToken length]; i++) {
[token appendFormat:#"%02.2hhX", data[i]];
}
[[NSUserDefaults standardUserDefaults] setObject:token forKey:#"DeviceToken"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
-(void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
[self respondToEventNotification:userInfo];
}
-(void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
[self respondToEventNotification:userInfo];
}

Have you register your app with didFinishLaunchingWithOptions method for iOS8 like,
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) {
[[UIApplication sharedApplication] registerForRemoteNotifications];
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge
|UIRemoteNotificationTypeSound
|UIRemoteNotificationTypeAlert) categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
}
else
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
}
You have to consider registration process of Push Notification in iOS8.
May this help you.
