Dismiss an already delivered UILocalNotification?

Question

Is it possible to do this? UIApplication\'s scheduledLocalNotifications doesn\'t seem to return notifications that have already been delivered to t

Answer 1

You can solve this by adding your newly created notifications to your own NSMutableArray of notifications and check that array instead of app.scheduledLocalNotifications. Something like this:

Add a NSMutableArray to your Viewcontrollers .h file:

NSMutableArray *currentNotifications;

Initiate it when initiating your ViewController

currentNotifications = [[NSMutableArray alloc] init];

When initiating a notification, also add it to your array:

UILocalNotification *notification = [[UILocalNotification alloc] init];
...
[currentNotifications addObject:notification];
[[UIApplication sharedApplication] presentLocalNotificationNow:notification];

Later when you want to cancel that notification, look for it in your array instead. Also remove it from your array:

for (UILocalNotification *notification in currentNotifications) {
    if (someCondition) {
        [[UIApplication sharedApplication] cancelLocalNotification:notification];
        [currentNotifications removeObject:notification];
    }
}
