Facebook iOS SDK 3.0登录教程问题与FBSession [英] Facebook iOS SDK 3.0 Login Tutorial Issue with FBSession

问题描述

我正在尝试将一个应用程序放在一起，其基础是（希望）建立在Facebook iOS SDK 3.0教程上。

I am currently trying to put together an app - with the foundation of it being (hopefully) built on the Facebook iOS SDK 3.0 tutorial.

我的教程以下位于： http://developers.facebook.com/docs / tutorials / ios-sdk-tutorial / authenticate /

我发现在Facebook的各种SDK版本中有一些变化，当涉及到最终版本。

I have found there to be a few changes throughout the various SDK versions from Facebook when it comes to the final release.

然而，在代码编译之前，我有一个最后一个问题：

However I do have one final issue before the code will compile:

没有已知选择器的类方法sessionOpenWithPermissions：completionHandler：'

"No known class method for selector 'sessionOpenWithPermissions:completionHandler:'"

此错误指代以下代码：

- (void)openSession
{
    [FBSession sessionOpenWithPermissions:nil completionHandler:
     ^(FBSession *session, FBSessionState state, NSError *error) {
         [self sessionStateChanged:session state:state error:error];
     }];    
}

当查看Xcode中的FBSession.h文件时，没有提到 sessionOpenWithPermissions 。

When looking at the FBSession.h file in Xcode there is no mention of sessionOpenWithPermissions.

有人可以帮我吗？我是Objective-C / Xcode的新手，并通过火灾试用学习。

Can anyone please help me with regard to this? I am new to Objective-C/Xcode and am learning via trial by fire.

推荐答案

我遇到同样的问题，我的代码使用以下变更。

I ran into the same issue, got my code working with the below change.

//REPLACE
[FBSession sessionOpenWithPermissions:nil
                    completionHandler: ^(FBSession *session, FBSessionState state, NSError *error) {
                        [self sessionStateChanged:session state:state error:error];
                    }];

//WITH
[FBSession openActiveSessionWithPermissions:nil
                               allowLoginUI:YES
                          completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
                              [self sessionStateChanged:session state:state error:error];
                          }];

如果您点击该方法，您将获得有关要传递的参数的更多信息。
