    //navigation bar stuff here

    mcPickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 244, 320, 216)];
    mcPickerView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin;

    // setup the data source and delegate for this picker
    mcPickerDataSource = [[MCPickerDataSource alloc] init];
    mcPickerView.dataSource = mcPickerDataSource;
    mcPickerView.delegate = mcPickerDataSource;

    mcPickerView.showsSelectionIndicator = YES;
    [self.view addSubview:mcPickerView];
}

– (void)dealloc
{
    [mc dealloc];
    [mcPickerView dealloc];
    [mcPickerDataSource dealloc];
    [mcVal release];
    [super dealloc];
}
