UIPasscodeViewController

Want a Passcode view for your iPhone/iPod project ? Here's how to add a UIPasscodeViewController on your project with a few lines of code.

How to use

1. Copy UIPasscodeViewController.m and UIPasscodeViewController.h files to your source tree and add it to XCode project.
2. Import "UIPasscodeViewController.h" from your code.
3. Implement UIPasscodeViewControllerDelegate protocol.

Just #import the UIPasscodeViewController.h header

#import "UIPasscodeViewController.h"

Simple example of how to create UIPasscodeViewController:

` UIPasscodeViewController *passcodeViewController = [[UIPasscodeViewController alloc] initWithDelegate:self];

UINavigationController *navController = [[UINavigationController alloc]
                                         initWithRootViewController:passcodeViewController];

[self setNavigationController:navController];

[window addSubview:[navController view]];
[window makeKeyAndVisible];

[window release];
[navController release];

`

Your class will have to implement the UIPasscodeViewControllerDelegate protocol, and to implement the didShowPasscodePanel:panelView:, shouldChangePasscode:panelView:passCode:lastNumber: and didEndPasscodeEditing:panelView:passCode: methods from this protocol:

`

• (void) didShowPasscodePanel:(UIPasscodeViewController )passcodeView panelView:(UIView)panelView { [passcodeView setTitle:@"Set Passcode"];

  if([panelView tag] == kPasscodePanelOne) { [[passcodeView titleLabel] setText:@"Enter a passcode"]; }

  if([panelView tag] == kPasscodePanelTwo) { [[passcodeView titleLabel] setText:@"Re-enter your passcode"]; }

  if([panelView tag] == kPasscodePanelThree) { [[passcodeView titleLabel] setText:@"Panel 3"]; } }

• (BOOL)shouldChangePasscode:(UIPasscodeViewController )passcodeView panelView:(UIView)panelView passCode:(NSUInteger)passCode lastNumber:(NSInteger)lastNumber; { // Clear summary text [[passcodeView summaryLabel] setText:@""];

  return TRUE; }

• (BOOL)didEndPasscodeEditing:(UIPasscodeViewController )passcodeView panelView:(UIView)panelView passCode:(NSUInteger)passCode {

  NSLog(@"END PASSCODE - %d", passCode);

  if([panelView tag] == kPasscodePanelOne) { _passCode = passCode;

    return ![passcodeView nextPanel];
  

  }

  if([panelView tag] == kPasscodePanelTwo) { _retryPassCode = passCode;

    if(_retryPassCode != _passCode) {
        [passcodeView prevPanel];
        [[passcodeView summaryLabel] setText:@"Passcode did not match. Try again."];
        return FALSE;
    } else {
        [[passcodeView summaryLabel] setText:@"Good boy !"];    
    }
  

  }

  return TRUE; } `
