Facebook登录iOS 10的问题 [英] Facebook login issue with iOS 10

问题描述

我用Facebook登录我的应用程序。
尝试使用Facebook登录 iOS 10 ，iPhone模拟器6s。

  -canOpenURL：URL失败：fbauth2：/ - 错误：操作无法完成（OSStatus错误-10814）
 
 10814：kLSApplicationNotFoundErr 
 -10814启动服务数据库中的任何应用程序都不符合输入条件。 
  

我正在使用Facebook sdk版本 4.13.1。
在XCode 8之前，相同的代码正常工作。

任何帮助？
提前感谢

解决方案

错误状态 10814 基本上发生在 cantOpenUrl ，由 facebook 用于使用参数调用 url fbauth2：/ 。由于建议bt这个

发布在这篇文章中的论坛开发者问题

问题出在 FBSDLoginManager ，完成处理程序从未被调用

所以在调试中，作者将断点放在 FBSDKLoginManager.m atlogInWithBehavior：（FBSDKLoginBehavior）loginBehavior和查找weakSelf无法调用logInWithBehavior：serverConfiguration： serverConfigurationLoadError：

   - （void）logInWithBehavior：（FBSDKLoginBehavior）loginBehavior 
 {
 __weak __typeof __（self）weakSelf = self ; 
 [FBSDKServerConfigurationManager loadServerConfigurationWithCompletionBlock：^（FBSDKServerConfiguration * serverConfiguration，NSError * loadError）{
 [weakSelf logInWithBehavior：loginBehavior serverConfiguration：serverConfiguration serverConfigurationLoadError：loadError]; 
}]; 
} 
  

解决方案1：

将FBSDKLoginManager 变量作为属性更改，而不是用作函数变量。确保 FBSDKLoginManager 变量必须保持活动，直到完成处理程序调用

您可以打开 -Wimplicit-retain-self 警告，以便在块中意外引用 self 时发出警告。 a href =https://github.com/facebook/KVOController/issues/82 =noreferrer> Github问题

解决方案2：

您可以将这些添加到您的plist

 <密钥GT; NSAppTransportSecurity< /密钥GT; 
< dict> 
< key> NSExceptionDomains< / key> 
< dict> 
< key> akamaihd.net< / key> 
< dict> 
< key> NSIncludesSubdomains< / key> 
< true /> 
< key> NSThirdPartyExceptionRequiresForwardSecrecy< / key> 
< false /> 
< / dict> 
< key> facebook.com< / key> 
< dict> 
< key> NSIncludesSubdomains< / key> 
< true /> 
< key> NSThirdPartyExceptionRequiresForwardSecrecy< / key> 
< false /> 
< / dict> 
< key> fbcdn.net< / key> 
< dict> 
< key> NSIncludesSubdomains< / key> 
< true /> 
< key> NSThirdPartyExceptionRequiresForwardSecrecy< / key> 
< false /> 
< / dict> 
< / dict> 
< / dict> 
< key> LSApplicationQueriesSchemes< / key> 
< array> 
< string> fbapi< / string> 
< string> fb-messenger-api< / string> 
< string> fbauth2< / string> 
< string> fbshareextension< / string> 
< / array> 
  

，并更改 AppDelegate 如下

  func应用程序（_应用程序：UIApplication，didFinishLaunchingWithOptions launchOptions：[UIApplicationLaunchOptionsKey：Any]？） - > Bool {
 //在应用程序启动后重写自定义点。 
返回SDKApplicationDelegate.shared.application（应用程序，didFinishLaunchingWithOptions：launchOptions）
} 
 func应用程序（_ app：UIApplication，打开url：URL，选项：[UIApplicationOpenURLOptionsKey：Any] = [：] ） - > Bool 
 {
 return SDKApplicationDelegate.shared.application（app，open：url，options：options）
} 
  

如作者所建议的
之后，您可以在 XCode8上运行您的 swift3，SDK，ios10

另请参阅作者，如果 Google Analytics（分析）将自己的控制器添加到设置

将embase -Info.plist 中的em>解决了这个问题。

I use facebook to login into my application. Trying to login using Facebook on iOS 10, iPhone simulator 6s.

-canOpenURL: failed for URL: "fbauth2:/" - error: "The operation couldn’t be completed. (OSStatus error -10814.)"

10814 : kLSApplicationNotFoundErr
-10814  No application in the Launch Services database matches the input criteria.

I am using facebook sdk version 4.13.1. Before XCode 8, same code was working perfectly.

Any Help ? Thanks in advance.

解决方案

Error status 10814 occurs basically when cantOpenUrl,which is used by the facebook to call the url using the arguments fbauth2:/ .As suggested bt this thread,printing happens inside this function so you cant do anything much with that

Apple changed the way of working with IOS 10.To fix this issue you can go to

Targets > Capabilities > Enable Keychain Sharing

Here is a screenshot from the same thread linked above

As posted in this post the of the forums developor issues

The problem is with the FBSDLoginManager , the completion handler is never called

so in debuging, the author put the breakpoint in "FBSDKLoginManager.m" at "logInWithBehavior: (FBSDKLoginBehavior)loginBehavior" and findout that weakSelf getting nil and not be able to call "logInWithBehavior: serverConfiguration: serverConfigurationLoadError:"

   - (void)logInWithBehavior:(FBSDKLoginBehavior)loginBehavior  
    {  
      __weak __typeof__(self) weakSelf = self;  
      [FBSDKServerConfigurationManager loadServerConfigurationWithCompletionBlock:^(FBSDKServerConfiguration *serverConfiguration, NSError *loadError) {  
        [weakSelf logInWithBehavior:loginBehavior serverConfiguration:serverConfiguration serverConfigurationLoadError:loadError];  
      }];  
    }

Solution 1:

Change FBSDKLoginManager variable as property rather than using as function variable. Make sure, FBSDKLoginManager variable must remain alive until the completion handler call

You can turn on the -Wimplicit-retain-self warning to get a warning if you reference self accidentally in a block.Posted in the Github issues

Solution 2:

You can add these to your plist

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSExceptionDomains</key>
        <dict>
            <key>akamaihd.net</key>
            <dict>
                <key>NSIncludesSubdomains</key>
                <true/>
                <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
                <false/>
            </dict>
            <key>facebook.com</key>
            <dict>
                <key>NSIncludesSubdomains</key>
                <true/>
                <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
                <false/>
            </dict>
            <key>fbcdn.net</key>
            <dict>
                <key>NSIncludesSubdomains</key>
                <true/>
                <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
                <false/>
            </dict>
        </dict>
    </dict>
    <key>LSApplicationQueriesSchemes</key>
    <array>
        <string>fbapi</string>
        <string>fb-messenger-api</string>
        <string>fbauth2</string>
        <string>fbshareextension</string>
    </array>

and also changing the AppDelegate as follows

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
     return SDKApplicationDelegate.shared.application(application,     didFinishLaunchingWithOptions: launchOptions)
}
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool
{
    return SDKApplicationDelegate.shared.application(app, open: url,    options: options)
}

as suggested by author After this you can run your swift3,SDK,ios10 on XCode8

Also check as mention by the author if the Google Analytics was adding its own controller on the top of your view controller by setting

Setting "FirebaseAppDelegateProxyEnabled" to "NO" in the -Info.plist solved the problem.
