iOS 10测试版-TouchID登录不会弹出pin键盘

在iOS 9.x中，在尝试5次（3次然后2次）生物识别登录后，iOS会自动弹出一个默认pin码屏幕。这在iOS 10测试版中不会发生。它只是没有通过“CaneValuePolicy”检查。是否有人知道这只是iOS 10测试版中的一个bug，或者我是否需要添加代码来支持pin码屏幕

代码如下：

-(void)touchTester {
    LAContext *myContext = [[[LAContext alloc] init] autorelease];
    NSError *authError = nil;

    NSString *myLocalizedReasonString = @"Sign on with TouchID\u00AE or enter password.";
    myContext.localizedFallbackTitle = @"Enter Password";

    self.touchIdActive = NO;
    if ([myContext canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&authError]) {
        [myContext evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics
                  localizedReason:myLocalizedReasonString
                            reply:^(BOOL success, NSError *error) {
                                if (success) {
                                    self.touchIdActive = YES;
                                    dispatch_async(dispatch_get_main_queue(), ^{

                                        NSLog(@"Launching loginUser");
                                        [self loginUser:YES];
                                    });
                                } else {
                                    self.touchIdActive = NO;

                                    NSString * errMsg = error.localizedDescription;
                                    if (![errMsg isEqualToString:@"Canceled by user."]) {
                                        dispatch_async(dispatch_get_main_queue(), ^{
                                            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error"
                                                                                                message:errMsg
                                                                                               delegate:self
                                                                                      cancelButtonTitle:@"OK"

                                    }
                                }
                            }];
    } else {
        // This is where we go after lockout in iOS 10
        dispatch_async(dispatch_get_main_queue(), ^{
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error"
                                                                message:authError.localizedDescription

                                                      otherButtonTitles:nil, nil];
            [alertView show];
        });
    }
}

你有什么iOS Beta 10。我有7个。但是iOS10的每一个测试版都让我在这个夏天工作。请描述一下你的情况。你能展示一下你的代码吗？我今天刚加载了。电话打10。（14A5345a）。基本上，我在我的应用程序中添加了TouchID支持。它有一个“自动”功能，如果您连续三次未能通过生物特征验证，它将返回一个“超出自动重试限制”错误。如果您再试一次，但又两次未通过生物特征验证，iOS 10将返回“生物测定已锁定”错误。在iOS 9中，在后一种情况下，你会得到一个键盘，允许你重新输入你的TouchID pin。我有7个。但是iOS10的每一个测试版都让我在这个夏天工作。请描述一下你的情况。你能展示一下你的代码吗？我今天刚加载了。电话打10。（14A5345a）。基本上，我在我的应用程序中添加了TouchID支持。它有一个“自动”功能，如果您连续三次未能通过生物特征验证，它将返回一个“超出自动重试限制”错误。如果您再试一次，但又两次未通过生物特征验证，iOS 10将返回“生物测定已锁定”错误。在iOS 9中，后一种情况下，您可以使用键盘重新输入TouchID pin。
