Question

在iOS 9.x中，经过5次（3次2次）尝试生物识别登录后，iOS会自动弹出默认的PIN码屏幕。这在iOS 10 Beta中不会发生。它只是失败了＆＃34; canEvaluatePolicy＆＃34;检查一下。有谁知道这只是iOS 10 Beta中的一个错误，还是我必须添加代码来支持pin代码屏幕？

以下是代码：

-(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(), ^{

                                                                                               delegate:self
                                                                                      cancelButtonTitle:@"OK"
                                                                                      otherButtonTitles:nil, nil];
                                            [alertView show];
                                        });
                                    }
                                }
                            }];
    } else {
        // This is where we go after lockout in iOS 10
        dispatch_async(dispatch_get_main_queue(), ^{
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error"
