Simple to use iOS 7 style Passcode - the one you get in Settings when changing your passcode.
Drag the contents of LTHPasscodeViewController to your project, or add pod 'LTHPasscodeViewController' to your podspec file.
Example, called in application:didFinishLaunchingWithOptions:
[LTHPasscodeViewController useKeychain:NO];
if ([LTHPasscodeViewController doesPasscodeExist]) {
if ([LTHPasscodeViewController didPasscodeTimerEnd])
[[LTHPasscodeViewController sharedUser] showLockScreenWithAnimation:YES
withLogout:NO
andLogoutTitle:nil];
}- Supports simple (4 digit) and complex passcodes.
- Data us saved in the Keychain, by default. Supports custom saving, by calling
[LTHPasscodeViewController useKeychain:NO]after initializing and implementing a few protocol methods (the same names the library uses for the same job):
- (void)passcodeViewControllerWillClose;
- (void)maxNumberOfFailedAttemptsReached;
- (void)passcodeWasEnteredSuccessfully;
- (void)logoutButtonWasPressed;
- (NSTimeInterval)timerDuration;
- (void)saveTimerDuration:(NSTimeInterval)duration;
- (NSTimeInterval)timerStartTime;
- (void)saveTimerStartTime;
- (BOOL)didPasscodeTimerEnd;
- (void)deletePasscode;
- (void)savePasscode:(NSString *)passcode;
- (NSString *)passcode;
// All of them fall back on the Keychain if they are not implemented, even if [LTHPasscodeViewController useKeychain:NO] was called, for flexibility over what and where you save.
// Do you only want to save the passcode in a different location and leave everything else in the Keychain? Call [LTHPasscodeViewController useKeychain:NO], but only implement -savePasscode:- Open as a modal, or pushed for changing, enabling or disabling the passcode:
/**
@param viewController The view controller where the passcode view controller will be displayed.
@param asModal Set to YES to present as a modal, or to NO to push on the current nav stack.
*/
- (void)showForEnablingPasscodeInViewController:(UIViewController *)viewController asModal:(BOOL)isModal;
- (void)showForDisablingPasscodeInViewController:(UIViewController *)viewController asModal:(BOOL)isModal;
- (void)showForChangingPasscodeInViewController:(UIViewController *)viewController asModal:(BOOL)isModal;- Show the lock screen:
- (void)showLockScreenWithAnimation:(BOOL)animated withLogout:(BOOL)hasLogout andLogoutTitle:(NSString*)logoutTitle;
// Example:
[[LTHPasscodeViewController sharedUser] showLockscreenWithAnimation:YES withLogout:NO andLogoutTitle:nil];
// Displayed with a slide up animation, which, combined with
// the keyboard sliding down animation, creates an "unlocking" impression.- entering foreground and resigning is handled from within the class.
Makes use of SFHFKeyChainUtils to save the passcode in the Keychain. I know he dropped support for it, but I updated it for ARC 2 years ago (with help) and I kept using it since. The 'new' version isn't updated to ARC anyway, so I saw no reason to switch to it, or to any other library.
