localNotification / uiTableView / delete row -> ERROR "invalid number of rows"

Question

This is my ERROR:

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (2) must be equal to the number of rows contained in that section before the update (2), plus or minus the number of rows inserted or deleted from that section (0 inserted, 1 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).'

I know what that means but I cant find my mistake in code. I know that I have to use NSMutableArry, only. Not a normale NSArray.This is the Point I think...

In my h. File: NSMutableArray *notifArray, IBOutlet UITableView *myTable;

CODE:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
        // Return the number of rows in the section.
        return [[[UIApplication sharedApplication] scheduledLocalNotifications] count];

    }

CODE:

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
    }

    // Configure the cell...

    NSArray *_notifArray = [[UIApplication sharedApplication] scheduledLocalNotifications];
    UILocalNotification *notif = [_notifArray objectAtIndex:indexPath.row];
    <...>

CODE:

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
        // If row is deleted, remove it from the list.
        if (editingStyle == UITableViewCellEditingStyleDelete) {
            [notifArray removeObjectAtIndex:indexPath.row];
            [self.myTable deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];

            [myTable reloadData];
        }
    }

CODE:

- (IBAction) scheduleAlarm:(id) sender {
    [eventText resignFirstResponder];

    NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];

    // Get the current date
    NSDate *pickerDate = [self.datePicker date];

    // Break the date up into components
    NSDateComponents *dateComponents = [calendar components:( NSYearCalendarUnit | NSMonthCalendarUnit |  NSDayCalendarUnit ) 
                                                   fromDate:pickerDate];
    NSDateComponents *timeComponents = [calendar components:( NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit ) 
                                                   fromDate:pickerDate];

    // Set up the fire time
    NSDateComponents *dateComps = [[NSDateComponents alloc] init];
    [dateComps setDay:[dateComponents day]];
    [dateComps setMonth:[dateComponents month]];
    [dateComps setYear:[dateComponents year]];
    [dateComps setHour:[timeComponents hour]];
    // Notification will fire in one minute
    [dateComps setMinute:[timeComponents minute]];
    [dateComps setSecond:[timeComponents second]];
    NSDate *itemDate = [calendar dateFromComponents:dateComps];
    [dateComps release];

    localNotification = [[UILocalNotification alloc] init];
    if (localNotification == nil)
        return;
    localNotification.fireDate = itemDate;
    localNotification.timeZone = [NSTimeZone defaultTimeZone];

    // Notification details
    localNotification.alertBody = [eventText text];
    // Set the action button
    localNotification.alertAction = @"View";

    localNotification.soundName = UILocalNotificationDefaultSoundName;
    localNotification.applicationIconBadgeNumber = 1;

    // Specify custom data for the notification
    NSDictionary *infoDict = [NSDictionary dictionaryWithObject:@"someValue" forKey:@"someKey"];
    localNotification.userInfo = infoDict;

    // Schedule the notification
    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
    [localNotification release];


    [self.myTable reloadData];
}

If I change this line to a NSMutabelArray than I got an error, too. "Incompatible pointer types initializing "NSMUtableArray" with an expression of type "NSArray*"

---> NSArray *_notifArray = [[UIApplication sharedApplication] scheduledLocalNotifications];

So what can I do, that it is possible to delete the row including a localNotification?

THANKS A LOT!!!

I think my Problem was at first a wrong code ;-) and at second I forgot that a notification displyed in a row are TWO THINGS! So I have to delete AT FIRST theNotification and second time theRow in my tableView ;-)

Here is my code - feel free ;-)

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
// If row is deleted, remove it from the list.
     if (editingStyle == UITableViewCellEditingStyleDelete)
           {

            // DELETE theNotification defined in (UITableViewCell *)tableView:{}
            [[UIApplication sharedApplication] cancelLocalNotification:notifcation];

            // DELETE theRow
            [notificationsArray removeObjectAtIndex:indexPath.row];
            [tableView deleteRowsAtIndexPaths:[NSMutableArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationLeft];

            [tableView reloadData];
    }    

}

YEEAARRR Im so happy ;-) Im really new in coading anyway ;-) - So If anybody has a better way feel free to correct me :-)
