iOS：使用Facebook登錄並打開本機Facebook應用程序

我想在登錄時打開Facebook應用程序，該應用程序已經安裝在設備中進行登錄驗證，但始終在Safari瀏覽器中打開。

- Facebook的按鈕，點擊iOS：使用Facebook登錄並打開本機Facebook應用程序

-(void)loginButtonClicked 
     { 
      FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init]; 

     // [login setLoginBehavior:FBSDKLoginBehaviorNative]; 

       [login logInWithReadPermissions:@[@"email"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) 
       { 
        if (error) 
        { 
         NSLog(@"Login process error"); 
        } 
        else if (result.isCancelled) 
        { 
         NSLog(@"User cancelled login"); 
        } 
        else 
        { 
         NSLog(@"Login Success"); 
         if ([result.grantedPermissions containsObject:@"email"]) 
         { 
          NSLog(@"result is:%@",result); 
          [self fetchUserInfo]; 
         } 
         else 
         { 
     //      [SVProgressHUD showErrorWithStatus:@"Facebook email permission error"]; 
         } 
        } 
       }]; 
      } 
     }

，尤其是圓形獲取用戶信息

 -(void)fetchUserInfo 
     { 
      if ([FBSDKAccessToken currentAccessToken]) 
      { 
       NSLog(@"Token is available : %@",[[FBSDKAccessToken currentAccessToken]tokenString]); 

       [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"id, name, email"}] 
       startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) { 
        if (!error) 
        { 
         NSLog(@"results:%@",result); 

         NSString *email = [result objectForKey:@"email"]; 
         NSString *userId = [result objectForKey:@"id"]; 

         if (email.length >0) 
         { 
          NSString *accessToken = [[FBSDKAccessToken currentAccessToken] tokenString]; 
          [ref authWithOAuthProvider:@"facebook" token:accessToken 
            withCompletionBlock:^(NSError *error, FAuthData *authData) 
           { 
             if (error) 
             { 
              NSLog(@"Login failed. %@", error); 
             } 
             else 
             { 
              NSLog(@"Logged in! %@", authData); 

              //Start you app Todo 
             } 
         else 
         { 
          NSLog(@"Facebook email is not verified"); 
         } 
        } 
        else 
        { 
         NSLog(@"Error %@",error); 
        } 
       }]; 

     }

我想打開Facebook應用與Facebook的登錄。

http://stackoverflow.com/questions/32566734/native-facebook-app-does-not-open-with-facebook-login-in-ios-9 檢查此鏈接。 –

此代碼已經使用，但不是在fb應用程序中打開，總是瀏覽器，我用新的sdk 4x –

我不是在這個組中 –

請使用FBLoginView如Facebook簽到按鈕，它會自動檢測的Facebook應用程序&ü可以能夠與Facebook登錄。 FBLoginView Facebook SDK中提供的類。

我使用了新的sdk，所以我可以這樣做嗎？ –

是的，在新的SDK中你會得到這個類 – SM18

從V4.6.0它不會重定向到FB應用程序。見下面

（v4.6.0 - 2015年9月10日）另外，SDK對話框如登錄，贊，分享對話框自動判斷基於在設備上，包括SFSafariViewController的Safari瀏覽器，而不是最好的UI。請參閱我們的準備iOS 9指南。

請正確設置參數的Info.plist，你可能沒有提供的網址這樣

<array> 
     <dict> 
      <key>CFBundleURLSchemes</key> 
      <array> 
       <string>fb776035152513539</string> 
      </array> 
     </dict> 
</array>

和

<key>FacebookAppID</key> 
<string>776035152513539</string>

如果你不能夠實現你想要什麼，那麼你可以使用這些類。

     } 
    }]; 

} 

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation 
{ 
    return [[FBSDKApplicationDelegate sharedInstance] application:application 
                  openURL:url 
               sourceApplication:sourceApplication 
                 annotation:annotation]; 

} 

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    return [[FBSDKApplicationDelegate sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions]; 
} 

@end

添加FBSDKCoreKit.Framework和FBSDKLoginKit.Framework在您的項目，並設置你的應用程序Delefate這樣的 -

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; 
    self.window.backgroundColor=[UIColor blackColor]; 

SplashViewController *rVC = [[SplashViewController alloc] initWithNibName:@"SplashViewController" bundle:nil]; 

    self.mNavController=[[UINavigationController alloc]initWithRootViewController:rVC]; 
    [self.mNavController setNavigationBarHidden:YES]; 

    self.window.rootViewController=self.mNavController; 
    [self.window makeKeyAndVisible]; 

    self.handler = [[LxFaceBookHandler alloc]init]; 



    [self.handler application:application didFinishLaunchingWithOptions:launchOptions]; 
    return YES; 
} 
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation 
{ 
    return [self.handler application:application openURL:url sourceApplication:sourceApplication annotation:annotation]; 
}

現在你可以使用這些類作爲任何事件假設在按鈕上點擊 -

- (IBAction)FacebookLoginPressed:(UIButton *)sender 
{ 
    App.handler.delegate = self; 
    [App.handler InitFaceBookLogin]; 
}
