Facebook sdk不使用已安裝的應用程序進行登錄iOS 10.0

Question

我想使用Facebook應用程序，如果它安裝在通過我的iOS應用程序中的Facebook登錄設備上。現在它重定向到Safari瀏覽器，無論是否安裝了應用程序？

任何幫助，將不勝感激。

謝謝。

Facebook登錄政策已更改。沒有錯，iOS的10

參考 - https://developers.facebook.com/docs/facebook-login/ios

你必須給行爲，以原生像下面。

login.loginBehavior = FBSDKLoginBehaviorNative; 

確保1件事，如果用戶沒有Facebook應用程序，那麼。

所以更好使用。這將僅在應用程序內的登錄視圖控制器上打開Facebook登錄頁面。

login.loginBehavior = FBSDKLoginBehaviorWeb; 

示例代碼

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

    login.loginBehavior = FBSDKLoginBehaviorNative; 

    [login 
    logInWithReadPermissions: @[@"public_profile",@"email"] 
    fromViewController:self 
    handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) { 
     if (error) { 
      NSLog(@"Process error"); 

     } 
     else if (result.isCancelled) 
     { 
      NSLog(@"Cancelled"); 
     } 
     else { 
      if ([FBSDKAccessToken currentAccessToken]) { 
       [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"email, name"}] 
        startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) { 
         if (!error) { 
          NSLog(@"fetched user:%@", result); 

         } 
        }]; 
      } 
     } 
    }]; 

只需點擊FBSDKLoginBehaviorNative，它會引導你到FacebookLoginManager.h

正確閱讀和理解。

typedef NS_ENUM(NSUInteger, FBSDKLoginBehavior) 
{ 
    /*! 
    @abstract This is the default behavior, and indicates logging in through the native 
    Facebook app may be used. The SDK may still use Safari instead. 
    */ 
    FBSDKLoginBehaviorNative = 0, 
    /*! 
    @abstract Attempts log in through the Safari or SFSafariViewController, if available. 
    */ 
    FBSDKLoginBehaviorBrowser, 
    /*! 
    @abstract Attempts log in through the Facebook account currently signed in through 
    the device Settings. 
    @note If the account is not available to the app (either not configured by user or 
    as determined by the SDK) this behavior falls back to \c FBSDKLoginBehaviorNative. 
    */ 
    FBSDKLoginBehaviorSystemAccount, 
    /*! 
    @abstract Attempts log in through a modal \c UIWebView pop up 

    @note This behavior is only available to certain types of apps. Please check the Facebook 
    Platform Policy to verify your app meets the restrictions. 
    */ 
    FBSDKLoginBehaviorWeb, 
};
