Question

我正在使用Xcode 7.0，在iOS 9.0.2上测试并使用Facebook SDK 4.7.0。 代码= 308＆＃34;（null）＆＃34; 问题发生在iOS 9中。我在我的项目中使用了objective-c代码。怎么解决这个？下面附上我的代码。

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

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

    if ([FBSDKAccessToken currentAccessToken]) { startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {

             if (!error) {
             }

         }];

    }
}];

Answer 1

iOS9.2.1

这解决了我的308问题

打开源代码＆＃39;，plist文件，搜索LSApplicationQueriesSchemes，然后根据需要添加/修改。

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fbauth2</string>
    <string>fbapi</string>
    <string>fb-messenger-api</string>
    <string>fbshareextension</string>
</array>

Answer 2

试试这段代码：

 FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
    login.loginBehavior = FBSDKLoginBehaviorWeb;
    [login logInWithReadPermissions:@[@"email"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
         if (error)
         {
             // Process error
         }
         else if (result.isCancelled)
         {
             // Handle cancellations
         }
         else
         {
             if ([result.grantedPermissions containsObject:@"email"])
             {
                 NSLog(@"result is:%@",result);
                 [self fetchUserInfo];
                 [login logOut];
             }
         }
     }];

Answer 3

我认为这与新的iOS 9网址处理方案有关

您需要将受信任的网址添加到plist密钥

下的LSApplicationQueriesSchemes
