THPinViewController *pinViewController = [[THPinViewController alloc] initWithDelegate:self];
pinViewController.promptTitle = @"Enter PIN";
pinViewController.promptColor = [UIColor darkTextColor];
pinViewController.view.tintColor = [UIColor darkTextColor];
pinViewController.hideLetters = YES;

// for a solid color background, use this:
pinViewController.backgroundColor = [UIColor whiteColor];

// for a translucent background, use this:
self.view.tag = THPinViewControllerContentViewTag;
self.modalPresentationStyle = UIModalPresentationCurrentContext;
pinViewController.translucentBackground = YES;

[self presentViewController:pinViewController animated:YES completion:nil];

// mandatory delegate methods

- (NSUInteger)pinLengthForPinViewController:(THPinViewController *)pinViewController
{
    return 4;
}

- (BOOL)pinViewController:(THPinViewController *)pinViewController isPinValid:(NSString *)pin

        return YES;
    } else {

        return NO;
    }
}
