IOS notification showing twice with default and my notification alert - ios

Question

I'm not an iOS programmer so bear with me. I'm able to get the push notifications but I get two alerts on my screens.
Issue 1:
-One with the UIAlertView* alertWindow I am creating below
- Second seems to be the default notification alert window. What am I doing wrong thats creating the second window ?
Issue 2: When the device is locked, I can see the notifications on screen but this is the default notification window. I don't see the notification with the details I'm getting in didReceiveRemoteNotification.
Also, I would appreciate If someone can explain the if else block in didFinishLaunchingWithOptions. I copied pasted it.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
NSString *AMAZON_SERVER = #"xxxxxx";
UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
UIUserNotificationTypeBadge |
UIUserNotificationTypeSound);
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes
categories:nil];
[application registerUserNotificationSettings:settings];
[application registerForRemoteNotifications];
[Parse initializeWithConfiguration:[ParseClientConfiguration configurationWithBlock:^(id<ParseMutableClientConfiguration> configuration) {
configuration.applicationId = APPLICATION_ID;
configuration.clientKey = CLIENT_KEY;
configuration.server = AMAZON_SERVER;
}]];
[PFAnalytics trackAppOpenedWithLaunchOptions:launchOptions];
[Fabric with:#[[Digits class]]];
if ([[UIApplication sharedApplication] respondsToSelector:#selector(registerUserNotificationSettings:)])
{
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
}
else
{
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
[application registerUserNotificationSettings:settings];
[application registerForRemoteNotifications];
if([[NSUserDefaults standardUserDefaults] boolForKey:#"FirstLaunch"]!=TRUE)
{
[[NSUserDefaults standardUserDefaults] setBool:FALSE forKey:#"FirstLaunch"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
//storedevice Type in standardUserDefaults
[self setDeviceType];
return YES;
}
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {
[application registerForRemoteNotifications];
}
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
// Store the deviceToken in the current installation and save it to Parse.
PFInstallation *currentInstallation = [PFInstallation currentInstallation];
[currentInstallation setDeviceTokenFromData:deviceToken];
[currentInstallation saveInBackground];
}
- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err {
NSLog(#"Error in registration. Error: %#", err);
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
[PFPush handlePush:userInfo];
if ([userInfo objectForKey:#"aps"]) {
NSMutableDictionary * apsData = [userInfo objectForKey:#"aps"];

...
...
UIAlertView* alertWindow = [[UIAlertView alloc] initWithTitle: alertHeader
message: message
delegate: self
cancelButtonTitle: #"OK"
otherButtonTitles: nil];
[alertWindow show];
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
} else {
[PFPush handlePush:userInfo];
}
}

Answer 1

First uninstall the app and try it. It will work fine same problem i am facing.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[Parse initializeWithConfiguration:[ParseClientConfiguration configurationWithBlock:^(id<ParseMutableClientConfiguration> configuration) {
configuration.applicationId = APPLICATION_ID;
configuration.clientKey = CLIENT_KEY;
configuration.server = AMAZON_SERVER;
}]];
[PFAnalytics trackAppOpenedWithLaunchOptions:launchOptions];
[Fabric with:#[[Digits class]]];
if([[NSUserDefaults standardUserDefaults] boolForKey:#"FirstLaunch"]!=TRUE)
{
[[NSUserDefaults standardUserDefaults] setBool:FALSE forKey:#"FirstLaunch"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
//storedevice Type in standardUserDefaults
[self setDeviceType];
#here i am edited
if ([[UIApplication sharedApplication] respondsToSelector:#selector(registerUserNotificationSettings:)])
{
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound) categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}
return YES;
}
// remove the below methods
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {
[application registerForRemoteNotifications];
}
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
// Store the deviceToken in the current installation and save it to Parse.
PFInstallation *currentInstallation = [PFInstallation currentInstallation];
[currentInstallation setDeviceTokenFromData:deviceToken];
[currentInstallation saveInBackground];
}
- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err {
NSLog(#"Error in registration. Error: %#", err);
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
//[PFPush handlePush:userInfo];
if ([userInfo objectForKey:#"aps"]) {
NSMutableDictionary * apsData = [userInfo objectForKey:#"aps"];
NSString* alert = [apsData objectForKey:#"alert"];
...
...
UIAlertView* alertWindow = [[UIAlertView alloc] initWithTitle: alertHeader
message: message
delegate: self
cancelButtonTitle: #"OK"
otherButtonTitles: nil];
[alertWindow show];
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
} else {
[PFPush handlePush:userInfo];
}
}

Your if statement says that if your [UIApplication sharedApplication] instance has implemented registerUserNotificationSettings: method, then it will execute if block, otherwise it will execute else block.
