我想使用TouchID验证我自己的应用程序.

1.我希望用户可以点击"输入密码"来调用系统内置密码屏幕进行身份验证,如果成功则输入我自己的应用程序.
但我不知道如何将它转发到密码验证视图,如'case LAErrorUserFallback'中的以下屏幕

这是我的代码:

LAContext *context = [[LAContext alloc] init];
__block  NSString *msg;
__block  BOOL bAuth;
// show the authentication UI with our reason string
[context evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics localizedReason:NSLocalizedString(@"Unlock APP With FingerPrint", nil) reply:
^(BOOL success, NSError *authenticationError) {

   if (success) {
      bAuth = YES;
      msg =[NSString stringWithFormat:NSLocalizedString(@"EVALUATE_POLICY_SUCCESS", nil)];
      dispatch_async(dispatch_get_main_queue(), ^{
         [[MYAppDelegate theDelegate] initializeAppAfterKeyVaultUnlocked];
      });
      NSLog(@"%@",msg);
   } else {
      bAuth = NO;
      switch (authenticationError.code) {
         case LAErrorAuthenticationFailed:
            msg = [NSString stringWithFormat:NSLocalizedString(@"Authentication Failed", nil)];
            // ...
            break;

         case LAErrorUserCancel: …

使用命令行查看diff代码非常困难.是否有任何GUI工具或只是使用语法高亮命令行工具来查看svn代码行的代码更改.

我正在使用Xcode6-beta5将触摸ID身份验证集成到我自己的应用程序中.使用以下代码运行在真实设备iphone5s(iOS8-beta5)上.已经#import.

LAContext *myContext = [[LAContext alloc] init];
NSError *authError = nil;
NSString *myLocalizedReasonString = @"use touch id to unlock app";

if ([myContext canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&authError]) {
     [myContext evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics
               localizedReason:myLocalizedReasonString
                         reply:^(BOOL success, NSError *error) {
                            if (success) {
                               UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"success" message:@"pass auth" delegate:self cancelButtonTitle:NSLocalizedString(@"OK", @"OK button") otherButtonTitles:nil];

                               [alert show];
                               [alert release];

                               // User authenticated successfully, take appropriate action
                            } else {
                               UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"fail" message:@"fail auth" delegate:self cancelButtonTitle:NSLocalizedString(@"OK", @"OK button") otherButtonTitles:nil];

                               [alert show];
                               [alert release]; …
