Is there a way to present a alert like the alert presented by twitter SDK if no account is signed-in.
I want to display that type of alert if user has disabled Settings->Notification Center for my app.
Just want to present the alert, mentioned twitter as ref. Its not about twitter.
NOTE: I don't want to display / use social media, its for reference, question is can we display a custom alert which can navigate the user to settings app of iOS.
There is no way to know the status of the switch in Notification Center > Your app. The only thing you can access is what type of notifications he will get ([[UIApplication sharedApplication] enabledRemoteNotificationTypes];).
You can know notification setting of your app and can show alert when it is disable as below
UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
if (!(types & UIRemoteNotificationTypeAlert)) {
UIAlertView *al = [[UIAlertView alloc] initWithTitle:#"TITLE" message:#"YOUR MESSAGE" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:#"Settings",nil];
[al show];
[al release];
}
For more reference, you may check Determine on iPhone if user has enabled push notifications
The only settings you can access are your app's settings, which can be within your app or in Settings app. Your app's settings are the ones you set/get with [NSUserDefaults standardUserDefaults]. However for your case you could schedule a notification which fires after one second, and see if you get called from - (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification. Here is an example code.
-(void) createLocalNofication{
UILocalNotification *local = [[UILocalNotification alloc] init];
local.fireDate = [NSDate dateWithTimeIntervalSinceNow:1.0f];
local.alertBody = #"Some Alert Body";
local.timeZone = [NSTimeZone defaultTimeZone];
[[UIApplication sharedApplication] scheduleLocalNotification:local];
}
- (void)application:(UIApplication *)application didReceiveLocalNotification: (UILocalNotification *)notification {
//Here you can set some flag
}

Im trying to implement the local notification to my app and I implemented the local notification but the problem is .... I'm not getting the Notification BANNER and SOUND when my app is in the foreground. But it is working good when my app is in background.
How to bring the notification banner and sound in foreground.. Is that possible?
this is my piece of code...
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Handle launching from a notification
UILocalNotification *locationNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (locationNotification) {
// Set icon badge number to zero
application.applicationIconBadgeNumber = 0;
}
}
- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo
{
if (application.applicationState == UIApplicationStateActive ) {
NSLog(#"it entered active push");
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.userInfo = userInfo;
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.alertBody = userInfo[#"aps"][#"alert"][#"body"];
localNotification.alertLaunchImage= userInfo[#"acme1"];
localNotification.fireDate = [NSDate date];
localNotification.applicationIconBadgeNumber = 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}
}
- (void)applicationWillEnterForeground:(UIApplication *)application
{
// Remove the badge number
application.applicationIconBadgeNumber = 0;
}
-(void)application:(UIApplication*)application didReceiveLocalNotification:(UILocalNotification *)notification{
UIApplicationState state = [application applicationState];
if (state == UIApplicationStateActive) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Reminder"
message:notification.alertBody
delegate:self cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
// Set icon badge number to zero
application.applicationIconBadgeNumber = 0;
}
If the app is active you will be notified by application:didReceiveLocalNotification: in app delegate only. There you can display custom banner like view on the top viewcontroller presented on the view hierarchy . Just look at the whatsapp notification when the app is open
If the application is active then you will not recieve any sound, badge or alert, however the application delegate application:didReceiveLocalNotification: will be called
From apple docs
If the application is foremost and visible when the system delivers the notification, no alert is shown, no icon is badged, and no sound is played. However, the application:didReceiveLocalNotification: is called if the application delegate implements it. The UILocalNotification instance is passed into this method, and the delegate can check its properties or access any custom data from the userInfo dictionary.
If your app is currently running and active (i.e. visible), you will not see the alert message. Instead iOS will deliver the notification to your app directly through the following method
- (void)application:(UIApplication *)application
didReceiveLocalNotification:(UILocalNotification *)notification
No it will not play a sound or show a banner. However in your apps delegate , did receive notification will still be called where you can then show an alert view if you wish to notify a user.
You can however add audio manually.
- (void) application:(UIApplication *)application didReceiveLocalNotification: (UILocalNotification *)notification
{
SystemSoundID systemSoundID;
NSURL *soundURL = [[NSBundle mainBundle] URLForResource:#"blip"
withExtension:#"mp3"];
AudioServicesCreateSystemSoundID((__bridge CFURLRef)soundURL, &systemSoundID);
AudioServicesPlaySystemSound(systemSoundID);
}
Local notification in Foreground
I send a LocalNotification like this:
UILocalNotification *notification = [UILocalNotification new];
notification.alertBody = #"Hello, open me";
notification.userInfo = #{#"TheKey": #"www.stackoverflow.com"};
notification.soundName = UILocalNotificationDefaultSoundName;
[[UIApplication sharedApplication] presentLocalNotificationNow:notification];
and in AppDelegate I do use:
-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
NSDictionary *userInfo = notification.userInfo;
NSURL *siteURL = [NSURL URLWithString:[userInfo objectForKey:#"TheKey"]];
[[UIApplication sharedApplication] openURL:siteURL];
}
It opens the URL in new broswer window but it takes like 5-10 seconds for the app to take that action. Is it possible to open browser immediatly when LocalNotification is opened?
On iOS 7 and prior your approach would indeed be the only one. This is because UILocalNotification is only used to open your app, i.e. call the AppDelegate's method application:didReceiveLocalNotification:. So, the first place indeed for you to perform any actions would be that method.
However, with iOS 8 interactive notifications have been introduced. These allow the user to perform a specified action without opening the app.
In the screenshot you see that the user just received a notification and now has the option to perform certain actions on it, without actually going back into the app. You can find a great tutorial on how to implement interactive notifications here!
Hello everyone,
I am trying how to implement pushnotification.For this i have read apple official document for push notification and also read raywenderlich blog and i understand the flow of pushnotication very well. I have created development and production certificate,profile and its working fine and push was successfully sent and receiving in -
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
*** display message in uialertview******
}
but my problem is how can i display push in my device like other push notification on top up side for both when my application is foreground and background too.
currently i am trying for IOS 7.0 and XCode Version 5.1.1 (5B1008)
Thanks In advance.
First of all check via these methods in App Delegate that if your registered successfully to APNS.
-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
}
-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
}
then in
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
NSDictionary *Notification = userInfo;
NSString *title = [(NSDictionary*)[(NSDictionary*)[Notification valueForKey:#"aps"] valueForKey:#"alert"] valueForKey:#"title"];
NSString *body = [(NSDictionary*)[(NSDictionary*)[Notification valueForKey:#"aps"] valueForKey:#"alert"] valueForKey:#"body"];
if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive)
{
}
else if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateInactive || [[UIApplication sharedApplication] applicationState] == UIApplicationStateBackground)
{
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.userInfo = userInfo;
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.alertBody = body;
localNotification.fireDate = [NSDate date];
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}
}
If your application is in active state show UIAlertView. if its not you need to show a UILocalNotification.
When you are in Background mode then push notification will display as per your application notification settings from notification centre. you dont have to display ios will do that.
when you are in Foreground mode then notification will receive and -(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo method will be called. so using this method you get userinfo. just NSLog userinfo dictionary and then you can create customview with label at top and animate it like ios default banner.
Hope this will help you.
As per Apple's note push/local notification will be display only when app is background mode. If notification is arrive at the time of app is on foreground/active then you need to manually manage it because iOS won't show a notification banner/alert That's default design.
I just put my logic here for manage notification when app in foreground mode:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
// check the application state for app is active or not.
if (application.applicationState == UIApplicationStateActive)
{
// Nothing to do if applicationState is Inactive, the iOS already displayed an alert view.
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Receive a Remote Notification" message:[NSString stringWithFormat:#"Your App name received this notification while it was running:\n%#",[[userInfo objectForKey:#"aps"] objectForKey:#"alert"]]delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
}
}
If you want to receive notification in top of the device like banner style then follow these steps.
First, you need to launch the 'Settings' app on your iOS device.
Once you're in, choose 'Notifications' from the list of options.
Here's a list of every app that supports push notifications. The ones at the top have been granted permission by you
You can also set the alert style. You can choose the banners that conveniently appear at the top of the screen, or full-on pop-ups that force you to take action before they go away. Or you can just choose 'None'.
For more detail check this link.
Hope you will get something from my answer.
I got my push notification successfully in both background and foreground but my problem is when my application is in active state/foreground and push notification is arrived then i show this pushnotification message on alertview using didReceiveRemoteNotification method,
My alert view have two buttons
1) later
2) Ok.
If I press 1) "later" button then I want add this pushnotification message in notification area so after some time user can see and tap on that particular push notification and go with that and that record of push notification will remove from notification area.
This is not possible. There is no API to access notification are of iOS.
Alternative
What near alternative you can try is Local Notification. When user select later set Local Notification for that thing. You can add this Local Notification when user leave your app so that you don't get notification while user is continue with your application.
Better Approach
The most general approach for this problem is Notification screen in app. Your application has one screen which has list of received notification so that user can check that in you app. I suggest you to go with this. Because this is most common and clear idea.
You need to implement core data for Notifications but it can only happen when your Application is is Active state.
1-create a new identity everytime a new notification arrive.
2-save it.
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
NSDictionary *Notification = userInfo;
NSString *title = [(NSDictionary*)[(NSDictionary*)[Notification valueForKey:#"aps"] valueForKey:#"alert"] valueForKey:#"title"];
NSString *body = [(NSDictionary*)[(NSDictionary*)[Notification valueForKey:#"aps"] valueForKey:#"alert"] valueForKey:#"body"];
XXNotification *objNotification = [XXNotification create];
objNotification.title = title;
objNotification.detail = body;
[XXNotification save:nil];
NSArray *arrNotification =[XXNotification allUnRead:nil];
[UtilityFunctions setApplicationBadgeNumber:[arrNotification count]];//Utility functions is my class for common functions.
if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive)
{
[UtilityFunctions showAlertView:title message:body delegate:self cancelButtonTitle:#"Ok" otherButtonTitle:#"Cancel" withTag:99 withAccessibilityHint:[NSString stringWithFormat:#"%#:|:%#", title,body]];
}
else if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateInactive || [[UIApplication sharedApplication] applicationState] == UIApplicationStateBackground)
{
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.userInfo = userInfo;
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.alertBody = body;
localNotification.fireDate = [NSDate date];
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
if (![IsLocationSaved isEqualToString:#"NO"])
{
[[NSNotificationCenter defaultCenter]postNotificationName:kNotificationForShowingNotification object: nil userInfo:nil];
}
}
}
On showing the UIAlertView, on its click event either delete that notification in DB or make a bool in it as isRead and make it YES. then save it,
On Notifications list Query the notification from DB or only those whose isRead = NO.
That is the way I did it in My Application.
I have successfully used APNS in iphone app and still have a problem the alert customization.Below is my question:
1 I can't custom the Alert view,like title and button title.I custom the alert like:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
NSDictionary *apsDic = [userInfo valueForKey:#"aps"];
NSString *alertStr = [apsDic valueForKey:#"alert"];
NSNumber *badgeNum = [apsDic valueForKey:#"badge"];
NSString *soundStr = [apsDic valueForKey:#"sound"];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:[arr objectAtIndex:1]
message:msg
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:#"view",nil];
[alert show];
[alert release];
}
In my App, the title of the alert is my app's title;and the button titles are "Close" and "View".
2 when I click the "View", is shows the launch view of my app and then it crashes.Why?
So if the alert is provided by the system which can't be customized, the view action is also under control of system. It seems there's contradiction between 1 and 2.
Any help is appreciated!
thanks
I find: if your app does not start, the apns-alert is provided by the iOS which you can't customize.
