NSNotification Called, but label will not update

I have the following code called with NSNotification center, i know its being called because the array is appearing in the NSLog, but my label chipCount is not updating with the new value. Is there perhaps a method I applied wrong when extracting the string from the array?

-(NSString *) dataFilePath {
    NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentDirectory = [path objectAtIndex:0];
    return [documentDirectory stringByAppendingPathComponent:@"Chips.plist"];
}

-(void)readPlist {
    [self dataFilePath];
    NSString *filePath = [self dataFilePath];
    if([[NSFileManager defaultManager] fileExistsAtPath:filePath]) {
        chipArray = [[NSArray alloc] initWithContentsOfFile:filePath];
        NSLog(@"%@\n", chipArray);
        NSLog(@"%@\n", filePath);

        NSString *chipcountString = [chipArray objectAtIndex:0];
        chipsFloat = [chipcountString intValue];
        chipCount.text = [NSString stringWithFormat:@"%i", chipsFloat];
        //[arrayForPlist release];
    }
}

I think this is a multithread problem. Update UI must in the main thread. Maybe readPlist is
executed in another thread.

Try this code below, maybe it can help you:

[self performSelectorOnMainThread:@selector(theProcess:) withObject:nil waitUntilDone:YES]; 

- (void) theProcess:(id)sender
{

    ....

    chipCount.text = [NSString stringWithFormat:@"%i", chipsFloat];

}

Assusming that chipcount is a UILabel.. is it possible that you need to tell it to refresh the label?

[chipcount setNeedsDisplay];

Just an idea.
