Question

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];
                               // User did not authenticate successfully, look at error and take appropriate action
                            }
                         }];
  } else {
     // Could not evaluate policy; look at authError and present an appropriate message to user
  }

但是当我编译并运行它时显示构建失败：

您似乎没有链接LocalAuthentication.framework。将其添加到Xcode中的应用程序目标（常规 - >链接框架和库 - ＆gt; + - ＆gt; LocalAuthentication.framework）。
