I'd like to schedule local notifications using iOS 10. I'd like to know how to do this. I've looked all around the web, but I keep finding clues only for registering and handeling the notifications. Not for the scheduling of a local notification.
So, does anyone know how to do this?
Try it. Its deprecated but working code. Use it for Before iOS 10.0 :
//Get all previous noti..
NSLog(@"scheduled notifications: --%@----", [[UIApplication sharedApplication] scheduledLocalNotifications]);
NSDate *now = [NSDate date];
now = [now dateByAddingTimeInterval:60*60*24*7]; //7 for 7th day of the week.
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
[calendar setTimeZone:[NSTimeZone localTimeZone]];
NSDateComponents *components = [calendar components:NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit|NSHourCalendarUnit|NSMinuteCalendarUnit|NSSecondCalendarUnit|NSTimeZoneCalendarUnit fromDate:now];
NSDate *SetAlarmAt = [calendar dateFromComponents:components];
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = SetAlarmAt;
NSLog(@"FIRE DATE --%@----",[SetAlarmAt description]);
localNotification.alertBody =@"Alert";
localNotification.alertAction = [NSString stringWithFormat:@"My test for Weekly alarm"];
localNotification.userInfo = @{
@"alarmID":[NSString stringWithFormat:@"123"],
@"SOUND_TYPE":[NSString stringWithFormat:@"hello.mp3"]
};
localNotification.repeatInterval=0; //[NSCalendar currentCalendar];
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
For iOS 10.0 and later: Now try with UserNotifications framework: Add the framework, and import like #import . In Appdelegate Didfinishluanch method.
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert)
completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (!error) {
NSLog(@"request succeeded!");
[self testAlrt];
}
}];
In your ibaction or method, write it and test:
NSDate *now = [NSDate date];
// NSLog(@"NSDate--before:%@",now);
now = [now dateByAddingTimeInterval:60*60*24*7];
NSLog(@"NSDate:%@",now);
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
[calendar setTimeZone:[NSTimeZone localTimeZone]];
NSDateComponents *components = [calendar components:NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit|NSHourCalendarUnit|NSMinuteCalendarUnit|NSSecondCalendarUnit|NSTimeZoneCalendarUnit fromDate:now];
NSDate *todaySehri = [calendar dateFromComponents:components]; //unused
UNMutableNotificationContent *objNotificationContent = [[UNMutableNotificationContent alloc] init];
objNotificationContent.title = [NSString localizedUserNotificationStringForKey:@"Notification!" arguments:nil];
objNotificationContent.body = [NSString localizedUserNotificationStringForKey:@"This is local notification message!"
arguments:nil];
objNotificationContent.sound = [UNNotificationSound defaultSound];
/// 4. update application icon badge number
objNotificationContent.badge = @([[UIApplication sharedApplication] applicationIconBadgeNumber] + 1);
UNCalendarNotificationTrigger *trigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:components repeats:NO];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"ten"
content:objNotificationContent trigger:trigger];
/// 3. schedule localNotification
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
if (!error) {
NSLog(@"Local Notification succeeded");
}
else {
NSLog(@"Local Notification failed");
}
}];
Follow the step: 1. Import UserNotifications.framework and go to your AppDelegate class.
In .h
#import <UserNotifications/UserNotifications.h>
@interface AppDelegate : UIResponder <UIApplicationDelegate,UNUserNotificationCenterDelegate>
@end
Register for push :
#define SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
Now add this in did finish launching :
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
[self registerForRemoteNotifications];
return YES;
}
- (void)registerForRemoteNotifications {
if(SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(@"10.0")){
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
center.delegate = self;
[center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error){
if(!error){
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
}];
}
else {
// Code for old versions
}
}
Delegate methods for UserNotifications :
//Called when a notification is delivered to a foreground app.
-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
NSLog(@"User Info : %@",notification.request.content.userInfo);
completionHandler(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge);
}
//Called to let your app know which action was selected by the user for a given notification.
-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler{
NSLog(@"User Info : %@",response.notification.request.content.userInfo);
completionHandler();
}
Push Notifications Entitlements : From project target’s Capabilities tab and add Push Notifications Entitlements.
Add push and mobile certificate properly. Hope this is everything you need!
