Is there no simple way of testing if the user has allowed local notifications? I noticed a warning in my console after I denied the sending of local notifications. When the relevant event occurred it said that the app tried to send a notifcation even though the user didn't allow it. I want to check if it's allowed before attempting to display a notification. See the comment in my condition, how do I do that?
My code is:
app = [UIApplication sharedApplication];
-(void)showBackgroundNotification:(NSString *) message {
//check if app is in background and check if local notifications are allowed.
if (app.applicationState == UIApplicationStateBackground /*&& LocalNotificationsAreAllowed*/){
UILocalNotification *note = [[UILocalNotification alloc]init];
note.alertBody = message;
note.fireDate = [NSDate dateWithTimeIntervalSinceNow:0.0];
[app scheduleLocalNotification :note];
}
}
I get prompt the user for permission like so:
UIUserNotificationSettings *settings;
if ([app respondsToSelector:@selector(registerUserNotificationSettings:)])
{
settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge|UIUserNotificationTypeAlert|UIUserNotification TypeSound) categories:nil];
[app registerUserNotificationSettings:settings];
}
couldn't I use settings object?
EDIT: I think I have solved it. This seems to work.
-(void)showBackgroundNotification:(NSString *) message {
if (app.applicationState == UIApplicationStateBackground && [app currentUserNotificationSettings].types != UIUserNotificationTypeNone){
UILocalNotification *note = [[UILocalNotification alloc]init];
note.alertBody = message;
note.fireDate = [NSDate dateWithTimeIntervalSinceNow:0.0];
[app scheduleLocalNotification :note];
}
}
Here's what I use for less specific situations:
+ (BOOL)notificationsEnabled {
UIUserNotificationSettings *settings = [[UIApplication sharedApplication] currentUserNotificationSettings];
return settings.types != UIUserNotificationTypeNone;
}
I usually keep a set of these types of methods in a notification manager.
