ios - -canOpenURL : failed for URL: "fbauth2:/" (OSStatus error -10814. )”

Question

我正在我的应用程序中添加 Facebook 和 Google 注册，但我遇到了这个问题

The operation couldn’t be completed. -10814

在 Facebook 登录中，我不知道如何解决它，这是我的 openUrl 的应用程序委托(delegate)代码:

 func application(_ application: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any])
        -> Bool {

            if let fbSDKAppId = FBSDKSettings.appID(), url.scheme!.hasPrefix("fb\(fbSDKAppId)"), url.host == "authorize" {
            var shouldOpen :Bool = FBSDKApplicationDelegate.sharedInstance().application(application,  open: url, sourceApplication:options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String!,annotation:options[UIApplicationOpenURLOptionsKey.annotation])
            return shouldOpen
            }
            else {
                return GIDSignIn.sharedInstance().handle(url,
                                                     sourceApplication:options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String,
                                                     annotation: [:])
                }

            }

我能做什么？

Answer 1

现在我使用了从here 下载的最新SDK v4.26.0我跟着link为 FB 安装的步骤。我的代码是

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];

if ([[[UIDevice currentDevice] systemVersion] floatValue] <= 9) {
    // After iOS9 we can not use it anymore
    login.loginBehavior = FBSDKLoginBehaviorSystemAccount;
} else {
    login.loginBehavior = FBSDKLoginBehaviorWeb;
}

NSArray *permission = [[NSArray alloc] initWithObjects:@"email",@"public_profile",@"user_friends", nil];
NSLog( @"### running FB sdk version: %@", [FBSDKSettings sdkVersion] );

[login logInWithReadPermissions:permission fromViewController:(UIViewController *)self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
    [self removeActivityIndicatorWithBg:activityIndicator];

    if (error) {
        NSLog(@"Process error");
    } else if (result.isCancelled) {
        NSLog(@"Cancelled");
    } else {
        NSLog(@"Logged in%@",result.grantedPermissions);
    }
}];

这里我使用登录行为作为 FBSDKLoginBehaviorSystemAccount 并且我得到错误作为

(- error: "The operation couldn’t be completed. -10814)

因此在我的模拟器或设备中不包含 facebook 系统设置中的帐户设置。然后它出现在下面的 block 上

if (error) {
    NSLog(@"Process error");
}

如果我打印错误，

No Facebook account. There are no Facebook accounts configured. You can add or create a Facebook account in Settings.

所以我将 loginBehavior 从 FBSDKLoginBehaviorSystemAccount 更改为 FBSDKLoginBehaviorWeb，我得到了所有 OP 而没有错误
