jopen 11年前發布 | 19K 次閱讀 iOS開發移動開發 THPinViewController

THPinViewController 實現了一個用于iOS7風格的數據鎖定碼用戶界面，也可以用于輸入數字密碼。類似 iOS 的解鎖應用。

特性：

Has iPhone portrait and iPad portrait and landscape layouts
Supports variable PIN lengths
Buttons can show numbers and letters or only numbers
Background and tint colors as well as text and color of the prompt can be customized
Supports solid color and translucent/blurred background

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 {}
