Question

I got list of all scheduled notifications using
[[UIApplication sharedApplication] scheduledLocalNotifications].

Now i want array of all firedates to compare it with today’s date and give an alertview telling the due today reminder.
i did it by this way but am not sure whether it will work fine. please correct me as am new to iphone development.

NSArray *arrayoflocalnotifications = [[NSArray alloc] initWithArray:[[UIApplication sharedApplication]scheduledLocalNotifications]];

for (UILocalNotification *localnotif in arrayoflocalnotifications)
{
     NSLog(@"array of firedate is %@", localnotif);

    if ([localnotif.fireDate isEqualToDate:[NSDate date]])
    {
        NSLog(@"Got a duetoday reminder...");

        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"AlertView" message:@"Due reminder for today" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil];
        [alert show];
        [alert release];
    }

}

Answer 1

Just use compare: function to compare two different dates. Use it like;

if(localnotif.fireDate compare:[NSDate date] == NSOrderedSame){
 // perform your operation here
}

compare: gives you flexibility to compare if the date is before or after certain date by comparing it to NSOrderedAscending/NSOrderedDescending.
