The error webview on ios - ios

My application is webview.
The normal it load page http://staging.nhomxe.vn.
But when server send a notify, and attachmented a link. Webview will open this link.
My application activity normal. Then, i add Navigation Controller to ViewControler.
When Server send notify, my webview notify error at [vc.webView loadRequest:urlRequest]; , and application auto exit.
My code:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeSound)];

Your rootViewController is returning a UINavigationController which is used to manage a navigation stack, that is represented by an array of view controllers.
To get your view controller try getting the topViewController, for example:
UINavigationController *navigationController = (UINavigationController *)self.window.rootViewController;
ViewController *vc = (ViewController *)navigationController.topViewController;
You can also get a array of all view controller that navigation manages by:
NSLog(#"%#", navigationController.viewControllers);
Update your UI on the main thread:
dispatch_async(dispatch_get_main_queue(), ^{
// make sure vc is a weak refernace to avoid retain cycle
[vc.webView loadRequest:urlRequest];
[vc.webView3 loadRequest:urlRequest];
});

How to manage openUrl method inside called application in iOS?

I suppose that this is duplicate but I can not figure it out.
I have to call other app from my iOS app using openUrl method. After finishing its work the other app must return to my app using the same method. I figure out how to call the other App and its open my App too. My problem is how to intercept the return to my App. I need to check the value from query string.
I find that method handleOpenURL intercepts return and I can handle my query string.
And here I am stuck - how to use that info inside my ViewController? I set breakpoint in viewDidLoad but it was not hit. Which method I have to use?
EDIT:
My Code is (inside AppDelegate):
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
NSLog(#"url recieved: %#", url);
NSLog(#"query string: %#", [url query]);
NSLog(#"host: %#", [url host]);
NSLog(#"url path: %#", [url path]);
NSDictionary *dict = [self parseQueryString:[url query]];
NSLog(#"query dict: %#", dict);
return YES;
}
- (NSDictionary *)parseQueryString:(NSString *)query {
NSMutableDictionary *dict = [[NSMutableDictionary alloc] initWithCapacity:6];
NSArray *pairs = [query componentsSeparatedByString:#"&"];
for (NSString *pair in pairs) {
NSArray *elements = [pair componentsSeparatedByString:#"="];
NSString *key = [[elements objectAtIndex:0] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *val = [[elements objectAtIndex:1] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[dict setObject:val forKey:key];
}
return dict;
}
Which works fine.
Inside my ViewController (VC):
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
[self setNeedsStatusBarAppearanceUpdate];
// Instantiate App singleton
singApp = [PESsingApplication sharedInstance];
#try {
// Localize resources using currently saved setting for language
[self setLocalizedResources];
// Init visual buttons
[self baseInit];
// Add code for keyboard management
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardShow:)
name:UIKeyboardWillShowNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardHide:)
name:UIKeyboardWillHideNotification
object:nil];
CGRect screenRect = [[UIScreen mainScreen] bounds];
_screenHeight = screenRect.size.height;
_screenWidth = screenRect.size.width;
}
#catch (NSException *exception) {
[self throwUnknownException:exception];
}
}
-(UIStatusBarStyle)preferredStatusBarStyle{
return UIStatusBarStyleLightContent;
}
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
}
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];

My url:
URL identifier: xx.mydomain.MyUrlScheme
URL shcemes: MyUrlScheme
I have breakpoints inside my VC (on each of the method shown above).
I use following string to call other app: #"otherApp://openApp?param1=value1&callbackUrl=MyUrlScheme";
They call me from the otherApp using callbackUrl param.
You need to make your own custom URL, please look below
How to implement Custom URL Scheme
Defining your app's custom URL scheme is all done in the Info.plist file. Click on the last line in the file and then click the "+" sign off to the right to add a new line. Select URL Types for the new item. Once that's added, click the grey arrow next to "URL Types" to show "Item 0". Set your URL identifier to a unique string - something like com.yourcompany.yourappname.
After you've set the URL identifier, select that line and click the "+" sign again, and add a new item for URL Schemes. Then click the grey arrow next to "URL Schemes" to reveal "Item 0". Set the value for Item 0 to be your URL scheme name.
Handling Custom URL Calls
In order for your app to respond when it receives a custom URL call, you must implement the application:handleOpenURL method in the application delegate class:
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
// your code
}
Parsing the Custom URL
There are several parts to a URL:
scheme://host/path?query
The parts to the URL can be retrieved through the NSURL object that is passed into the application:handleOpenURL method. If you have a fairly simple URL naming scheme and want to allow access to specific pages/keys, you can just use the host name:
Custom URL Value of [url host]:
myapp://page1 page1
myapp://page2 page2
myapp://otherPage otherPage
To pass data into your app, you'll want to use the query string. Here's a simple method for parsing the query string from the url:
- (NSDictionary *)parseQueryString:(NSString *)query {
NSMutableDictionary *dict = [[[NSMutableDictionary alloc] initWithCapacity:6] autorelease];
NSArray *pairs = [query componentsSeparatedByString:#"&"];
for (NSString *pair in pairs) {
NSArray *elements = [pair componentsSeparatedByString:#"="];
NSString *key = [[elements objectAtIndex:0] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *val = [[elements objectAtIndex:1] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[dict setObject:val forKey:key];
}
return dict;
}
Testing The Custom URL
You can easily test your URL scheme in the simulator. Just add a test button to one of your views, and implement the IBAction method for it as follows:
- (IBAction)getTest:(id)sender {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:#"myappscheme://test_page/one?token=12345&domain=foo.com"]];
}
Then in your app delegate, implement the application:handleOpenURL method:
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
NSLog(#"url recieved: %#", url);
NSLog(#"query string: %#", [url query]);
NSLog(#"host: %#", [url host]);
NSLog(#"url path: %#", [url path]);
NSDictionary *dict = [self parseQueryString:[url query]];
NSLog(#"query dict: %#", dict);
return YES;
}
Finally if you are looking method to receive your data anywhere you can use this two scenario.
You can simple use Local notification or NSUserDefault
NSUserDefault
- (BOOL)application:(UIApplication *)application handleopenURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
NSUserDefaults *userDefaults=[[NSUserDefaults alloc] init];
[userDefaults synchronize];
NSString *status = [defaults stringForKey:#"any status"];
}
Local notification
- (BOOL)application:(UIApplication *)application handleopenURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
if (localNotif == nil)
return;
localNotif.userInfo = [NSDictionary dictionaryWithObjectsAndKeys:VAL, #"value", nil];
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
}
If your viewDidLoad is not called perfectly try in viewWillAppear or viewDidAppear method.
For example purpose:
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
NSDictionary *dict = [self parseQueryString:[url query]];
NSLog(#"query dict: %#", dict);
// add dictionary to standardUserDefaults for saving purpose, like
[[NSUserDefaults standardUserDefaults] setObject:dict forKey:#"DicKey"];
[[NSUserDefaults standardUserDefaults] synchronize];
// add code for navigation/present view controller
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:#"Main"
bundle: nil];
YourViewController *yourController = (YourViewController *)[mainStoryboard
instantiateViewControllerWithIdentifier:#"YourViewControllerID"];
self.window.rootViewController = yourController;
return YES;
}
for retrieve
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
NSMutableDictionary *mutableRetrievedDictionary = [[[NSUserDefaults standardUserDefaults] objectForKey:#"DicKey"] mutableCopy];
// here parse the dictionary and do your work here, when your works is over
// remove the key of standardUserDefaults
[[NSUserDefaults standardUserDefaults] removeObjectForKey:#"DicKey"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
Store the status from other app in NSUserdefaults, when the ViewController of your app launches fetch the status into a NSString from NSUserdefaults and rise it as an alert.
Call the handleopenURL in appdelegate
- (BOOL)application:(UIApplication *)application handleopenURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
NSUserDefaults *defaults=[[NSUserDefaults alloc] init];
[defaults synchronize];
NSString *status = [defaults stringForKey:#"status string from other app"];
}

MWFeedParser check if data is new

I'm currently trying to make a RSS like iPhone application using MWFeedParser https://github.com/mwaterfall/MWFeedParser to parse my xml feed. Currently I'm trying to implement a background fetch into my app. When there are new items the user gets a local notification. I'm having a hard time checking if there are new entries in my RSS feed I'm currently using the code below. parsedItems is an NSArray which is automatically filled when [feedparser parse] is called. Now the problem is that parsedItems.count always returns zero although I refresh my feed. Any ideas?
In my app delegate I have the following function:
-(void)application:(UIApplication *)application performFetchWithCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler{
NewsTableViewController *viewController = [[NewsTableViewController alloc] init];
[viewController fetchNewDataWithCompletionHandler:^(UIBackgroundFetchResult result) {
completionHandler(result);
}];
}
And in my NewsTableViewController class I have the function:
-(void)fetchNewDataWithCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
NSArray *oldItems;
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSData *objectData = [defaults objectForKey:#"parsedItems"];
if(objectData != nil)
{
oldItems = [NSKeyedUnarchiver unarchiveObjectWithData:objectData];
oldItems = [oldItems sortedArrayUsingDescriptors:
[NSArray arrayWithObject:[[NSSortDescriptor alloc] initWithKey:#"date"
ascending:NO]]];
}
// Refresh data
[feedParser stopParsing];
[parsedItems removeAllObjects];
[feedParser parse];
NSLog(#"old:%lu", oldItems.count);
NSLog(#"new:%lu", parsedItems.count);
NSLog(#"ding:%lu", self.itemsToDisplay.count);
if (parsedItems.count == oldItems.count) {
completionHandler(UIBackgroundFetchResultNoData);
NSLog(#"No data.");
}
else {
[UIApplication sharedApplication].applicationIconBadgeNumber++;
[self sendNotification];
completionHandler(UIBackgroundFetchResultNewData);
[defaults setObject:[NSKeyedArchiver archivedDataWithRootObject:parsedItems] forKey:#"parsedItems"];
[defaults synchronize];
NSLog(#"New data was fetched.");
}
}

How to pass the device token from AppDelegate to UIViewController

Hi in my application I'm fetching the device token and I'm passing to my server to send the notification now I want to send the individual notification for the i need to fetch the device token form my UIViewController Please tell is there any possibilities fetching the device token form the Appdelegate or from the UIViewController
My code for fetching the device token in Appdelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeNone)];
return YES;
}
Device Token.
-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
const char* data = [deviceToken bytes];
NSMutableString * token = [NSMutableString string];
for (int i = 0; i < [deviceToken length]; i++) {
[token appendFormat:#"%02.2hhX", data[i]];
}
NSString *urlString = [NSString stringWithFormat:#"url?token=%#",token];
NSURL *url = [[NSURL alloc] initWithString:urlString];
NSLog(#"token %#",urlString);
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
NSLog(#"request %# ",urlRequest);
NSData *urlData;
NSURLResponse *response;
urlData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:nil];
NSLog(#"data %#",urlData);
}
I have used the to get the device token please tell me how to pass the device token to my UIViewController or how to fetch the device token from my UIViewController.
Use the NSUserDefaults to store the objects(values), you can access it anywhere.
AppDelegate (setValue) :
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
[[NSUserDefaults standardUserDefaults] setObject: token forKey:#"deviceID"];
[[NSUserDefaults standardUserDefaults]synchronize];
}
UIViewController (getValue) :
[[NSUserDefaults standardUserDefaults] objectForKey:#"deviceID"];
In AppDelegate.m class:
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
NSLog(#"My token is: %#", deviceToken);
NSString *device = [deviceToken description];
device = [device stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:#"<>"]];
device = [device stringByReplacingOccurrencesOfString:#" " withString:#""];
NSLog(#"My device is: %#", device);
[[NSUserDefaults standardUserDefaults] setObject:device forKey:#"MyAppDeviceToken"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
In ViewController class, inside viewDidLoad method:
[super viewDidLoad];
NSString *deviceToken = [[NSUserDefaults standardUserDefaults] objectForKey:#"MyAppDeviceToken"];
NSLog(#"device token in controller: %# ", deviceToken);
This is working perfectly in my device. Happy Coding !! :)
Try this coding in your view did load
NSString* deviceId = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
deviceId = [deviceId stringByReplacingOccurrencesOfString:#"-" withString:#""];
NSLog(#"%#",deviceId);
Declare and define below methods in your delegate file,
#pragma mark - Get / Set Device Token
+ (void)setDeviceToken:(NSString *)token {
if(token) {
[[NSUserDefaults standardUserDefaults] setObject:token forKey:#"DeviceToken"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
}
+ (NSString *)getDeviceToken {
NSString *token = [[NSUserDefaults standardUserDefaults] objectForKey:#"DeviceToken"];
if(token) {
return token;
}
return #"";
}
In -(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken method
call, [AppDelegate setDeviceToken:token]; once you get the token and
Now in project, in any view controller, you can call NSString *token = [AppDelegate getDeviceToken]; to get saved token, here note that, we call it with AppDelegate its name of your delegate file, and we call it with the class name, as we make a class method to set and get a token.
At the time of getting you can check for availability of saved token
NSString *token = [AppDelegate getDeviceToken];
if(token.length) {
// do something
}
You can get appDelegate instance in any view contoller and fetch value from that instance like -
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

Navigate to particular view controller when user tap the notification IOS7

Hi i have added push notification in my application and I want to view particular ViewControllers when the user tap the notification. In my app delegate m file I'm trying to get the register the device token to my server and from my server I'm using the php script to get the device token from server and I'm sending the notification.
The problem here I'm trying to view a particular view controller when the user taps on the notification its not working i have tried many different methods nothing had worked.
Here I'm view the popup like to send notification from the app when user trying to install application for the first time.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeNone)];
return YES;
}
- (void) clearNotifications {
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
}
Here I'm storing the device to token to my server.
-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
const char* data = [deviceToken bytes];
NSMutableString * token = [NSMutableString string];
for (int i = 0; i < [deviceToken length]; i++) {
[token appendFormat:#"%02.2hhX", data[i]];
}
NSString *urlString = [NSString stringWithFormat:#"url?token=%#",token];
NSURL *url = [[NSURL alloc] initWithString:urlString];
NSLog(#"token %#",urlString);
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
NSLog(#"request %# ",urlRequest);
NSData *urlData;
NSURLResponse *response;
urlData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:nil];
NSLog(#"data %#",urlData);
[self clearNotifications];
// NSLog(#"token ",sendUserToken);
}
Here I'm trying to view the particular method when user tap the notification.
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
updatepoliticalViewController *ringingVC = [self.window.rootViewController.storyboard instantiateViewControllerWithIdentifier:#"updatepoliticalViewController"];
[self.window.rootViewController presentViewController:ringingVC animated:YES completion:NULL];
}
My particular view controller name is updatepoliticalViewController its a navigation view controller please tell me in this above code where I'm doing wrong how to resolve this issue.
Thanks
When the app is in foreground state it call
application:didReceiveRemoteNotification:
but if it's not and the app is launched, for example, by swiping the alert in notification center
application:didFinishLaunchingWithOptions:
is called with key.
The good way is to call
application:didReceiveRemoteNotification:
from
application:didFinishLaunchingWithOptions:
I believe this should help
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
if (launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]) {
[self application:application didReceiveRemoteNotification:launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]];
}
// YOUR CODE...
return YES;
}
// EXTENDED
Try get storyboard like that:
// Make sure the name match
UIStoryboard *mainstoryboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
Create your object from mainstoryboard:
updatepoliticalViewController *ringingVC = [mainstoryboard instantiateViewControllerWithIdentifier:#"updatepoliticalViewController"];
And try set new root view controller
[self.window setRootViewController: ringingVC];
1) When application is running in background and When application is running in foreground
application:didReceiveRemoteNotification: method will called as below.
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
if ( application.applicationState == UIApplicationStateInactive)
{
//opened from a push notification when the app was on background
NSLog(#"userInfo->%#",[userInfo objectForKey:#"aps"]);
}
else if(application.applicationState == UIApplicationStateActive)
{
// a push notification when the app is running. So that you can display an alert and push in any view
NSLog(#"userInfo->%#",[userInfo objectForKey:#"aps"]);
}
}
2) When application is not launched (close) than application:didFinishedLaunchWithOptionsmethod will called.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
if (launchOptions != nil)
{
//opened from a push notification when the app is closed
NSDictionary* userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (userInfo != nil)
{
NSLog(#"userInfo->%#",[userInfo objectForKey:#"aps"]);
}
}
else{
//opened app without a push notification.
}
}

Enable push notifications via a UISwitch

I want to use a UISwitch to enable/disable push notifications. Like in Tweetbot.
Does anyone know how to trigger that?
You can also do it in the following way.
create a IBOutlet for UISwitch
#property (strong, nonatomic) IBOutlet *pushNotificationSwitch;
and in Action method, store the value in NSUserDefaults.
- (IBAction)pushNotificationSwitchChanged:(id)sender
{
NSNumber *switch_value = [NSNumber numberWithBool:[self.pushNotificationSwitch isOn]];
[[NSUserDefaults standardUserDefaults] setObject:switch_value forKey:RECIEVE_APNS];
[[NSUserDefaults standardUserDefaults] synchronize];
}
and check it in viewdidload.
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
NSNumber *sett = [[NSUserDefaults standardUserDefaults] valueForKey:RECIEVE_APNS];
if( [sett boolValue] )
{
[self.pushNotificationSwitch setOn:YES];
}
else{
[self.pushNotificationSwitch setOn:NO];
}
}
and In AppDelegate.m, add the following code
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
NSNumber *sett = [[NSUserDefaults standardUserDefaults] objectForKey:RECIEVE_APNS];
if( [sett boolValue] )
{
int currentBadgeCount = [[NSUserDefaults standardUserDefaults] integerForKey:#"BadgeCount"];
//Set the baadge count on the app icon in the home screen
int badgeValue = [[[userInfo valueForKey:#"aps"] valueForKey:#"badge"] intValue];
[UIApplication sharedApplication].applicationIconBadgeNumber = badgeValue + currentBadgeCount;
[[NSUserDefaults standardUserDefaults] setInteger:badgeValue + currentBadgeCount forKey:#"BadgeCount"];
NSString *alertString = [[userInfo objectForKey:#"aps"] objectForKey:#"alert"];
NSString *playSoundOnAlert = [NSString stringWithFormat:#"%#", [[userInfo objectForKey:#"aps"] objectForKey:#"sound"]];
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/%#",[[NSBundle mainBundle] resourcePath],playSoundOnAlert]];
NSError *error;
if (alertString.length > 0)
{
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"App Name" message:alertString delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = 1;
[audioPlayer play];
[alert show];
}
}
}
enter code here
You can not do that directly from the application. If you want to do this, you need to make the UISwitch send the information to your backend, store this information in your database and stop sending push notifications to this user.
An app registers for Push Notifications (APN) when it first launches. You cannot have it initialize APNs with a switch once it has already launched. You can however code your app that a switch can choose to do "something" with the user interface once a APN is received.
For example, you can have this code:
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
NSDictionary *apsInfo = [userInfo objectForKey:#"aps"];
NSString *alert = [apsInfo objectForKey:#"alert"];
// do what you need with the data...
[[NSNotificationCenter defaultCenter] postNotificationName:#"ReceivedNotificationAlert" object:self];
}
You can use your UISwitch to either do something, or not, with the NSNotification "ReceivedNotificationAlert". For example:
if(switchAPNprocess.on){
// process APN
}
else {
// ignore APN
}
