I am new to Objective C. In my app i need to implement push notification, i have created new app ID and i have created new provisioning profile also. i have finished all the steps mentioned in this link
i have declared this delegate function in my appDelegate .m file.
- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
NSString *deviceTokens = [[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];
deviceTokens = [deviceTokens stringByReplacingOccurrencesOfString:@" " withString:@""];
NSLog(@"registered device token %@", deviceTokens);
self.deviceToken = deviceTokens;
}
- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err {
NSString *str = [NSString stringWithFormat: @"Error: %@", err];
NSLog(@"String %@",str);
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
for (id key in userInfo) {
NSLog(@"key: %@, value: %@", key, [userInfo objectForKey:key]);
}
}
But this delegate functions are not called. please help me to fix this issue.
In your AppDelegated didfinishLaunching with options write the following line
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
Add this code to your application didFinishLaunchingWithOptions method, inside your app delegate
if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
//We check because ios7 cannot respond to this method and there will be a crash..
UIUserNotificationType types = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
UIUserNotificationSettings *mySettings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:mySettings];
[application registerForRemoteNotifications];
}
else {
//This will work on ios7 devices and below
UIRemoteNotificationType types = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
[application registerForRemoteNotificationTypes:types];
[application registerForRemoteNotifications];
}
return YES;
Use new delegate method
Swift:
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void)
