用法 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 { if ([pin isEqualToString:self.correctPin]) { return YES; } else { self.remainingPinEntries--; return NO; } } - (BOOL)userCanRetryInPinViewController:(THPinViewController *)pinViewController { return (self.remainingPinEntries > 0); } // optional delegate methods - (void)incorrectPinEnteredInPinViewController:(THPinViewController *)pinViewController {} - (void)pinViewControllerWillDismissAfterPinEntryWasSuccessful:(THPinViewController *)pinViewController {} - (void)pinViewControllerDidDismissAfterPinEntryWasSuccessful:(THPinViewController *)pinViewController {} - (void)pinViewControllerWillDismissAfterPinEntryWasUnsuccessful:(THPinViewController *)pinViewController {} - (void)pinViewControllerDidDismissAfterPinEntryWasUnsuccessful:(THPinViewController *)pinViewController {} - (void)pinViewControllerWillDismissAfterPinEntryWasCancelled:(THPinViewController *)pinViewController {} - (void)pinViewControllerDidDismissAfterPinEntryWasCancelled:(THPinViewController *)pinViewController {}
