FBSessionDelegate 方法未触发

Posted 2023-03-17

【中文标题】FBSessionDelegate 方法未触发

【英文标题】：FBSessionDelegate methods not firing

【发布时间】：2010-12-21 00:29:56

【问题描述】：

我正在尝试实施最新的 Facebook Connect SDK，但遇到了一些麻烦。由于某种原因，FBSessionDelegate 协议的委托回调没有被触发。我已按照 git Facebook 页面上的说明进行操作，并尝试模仿 Facebook 示例应用程序，但没有成功。我在这里发疯了，所以我要发布我的代码，也许有人会看到我错过的一些愚蠢的东西。

#import <Foundation/Foundation.h>
#import "FBConnect.h"

@interface FacebookWrapper : UIViewController <FBSessionDelegate, FBRequestDelegate, FBDialogDelegate>
 Facebook* _facebook;
 NSArray* _permissions;


@property(readonly) Facebook *facebook;

- (void)login;

@end

#import "FacebookWrapper.h"

static NSString* kAppId = @"1234455667778";

@implementation FacebookWrapper

@synthesize facebook = _facebook;

- (id)init 
 if (self = [super init]) 
  _permissions =  [[NSArray arrayWithObjects: @"read_stream", @"offline_access",nil] retain];
  _facebook = [[Facebook alloc] initWithAppId:kAppId];

 
 return self;


- (void)dealloc 
 [_facebook release];
 [_permissions release];
 [super dealloc];


- (void)login 
 [_facebook authorize:_permissions delegate:self];


- (void)fbDidLogin 
 NSLog(@"Did Log In");


- (void)fbDidNotLogin:(BOOL)cancelled 
 NSLog(@"Failed to log in");


- (void)fbDidLogout 
 NSLog(@"Logged Out");

从另一个类调用它，

FacebookWrapper *fw = [[FacebookWrapper alloc] init];
[fw login];

我在手机上看到的行为符合预期。 Facebook 应用程序在初始化时启动并请求权限。然后电话将我的应用程序带回前台，但FBSessionDelegate 的代表从未被解雇。我已经使用我的应用 ID 在 Facebook 示例应用中进行了尝试，并且效果很好。我不知道有什么区别。

【参考方案1】：

我发现了问题所在。在 App Delegate 中，您需要覆盖 handleOpenURL。

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url 
    return [[facebookWrapper facebook] handleOpenURL:url];

如果您像我一样创建一个包装类，您需要在应用程序委托中创建一个它的实例，以便您可以在 Facebook 类中调用 hanleOpenURL 方法。另请注意，我的 FacebookWrapper 类中的 Facebook 实例有一个公共只读属性，因此我可以调用handlOpenURL。

通过这样做，您的应用将知道在从 Facebook 应用内部获取权限返回时从哪里继续。

【讨论】：

我知道这是一篇旧帖子，但如果您还记得有关此问题的任何信息，那将会很有帮助。你会从视图控制器还是从应用程序委托调用：FacebookWrapper *fw = [[FacebookWrapper alloc] init]; [fw login];？如何从控制器和应用程序委托类中引用 FacebookWrapper 实例？谢谢

【参考方案2】：

我已经开发了对你很有帮助的包装类。

首先下载Facebook最新的SDK。

创建一个名为“FacebookHelper”的类

在 .h 文件中添加以下代码：

#import <Foundation/Foundation.h>
#import "FBConnect.h"

@protocol FBApiCallDelegate;

typedef enum FBApiCallType

FBApiCallShareLink = 5,
FBApiCallPostAll = 6,
FBApiCallPostMessageFriendWall = 7

 FBApiCallType;

@interface FacebookHelper : NSObject<FBRequestDelegate, FBDialogDelegate, FBSessionDelegate> 
Facebook *objFacebook;
NSArray *arrPermission;

就是这样。现在我们的 Facebook 包装类已经准备好了。

在班级下面创建 3 个以便更好地组织。

FacebookGlobal.h

添加以下数据：

#define g_kFacebookAppId        @"<Your AppID>"
#define g_kFacebookAppSecret    @"<Your Secret>"


#define g_kPostMessage          @"<Message>"
#define g_kPostUrlTitle         @"<Title>"
#define g_kPostUrl              @"<Url>"
#define g_kPostCaption          @"<Caption>"
#define g_kPostPictureUrl       @"<Image Url>"

FacebookKey.h

添加以下数据：

#define g_kFacebookAccessToken      @"FBAccessTokenKey"
#define g_kFacebookExpirationDate   @"FBExpirationDateKey"

FacebookMes​​sage.h

添加以下数据：

//AppID Missing 
#define msgFBAppIDMissing @"Missing AppID"

//Session Invalidated
#define msgFBSessionInvalidateTitle @"Auth Exception"
#define msgFBSessionInvalidateMessage @"Your session has expired."

在您的 .pch 文件中导入以下文件：

#import "FacebookGlobal.h"
#import "FacebookKey.h"
#import "FacebookMessage.h"

#import "FacebookHelper.h"

现在，您可以使用了。

在您的视图控制器中，添加以下委托：

<FBApiCallDelegate>

在您的视图控制器 .m 文件中，添加以下方法以调用以及委托：

- (void)viewWillAppear:(BOOL)animated 
/*
FacebookHelper *fbHelper = [FacebookHelper sharedInstance];
[fbHelper logoutFromFacebook];
*/


//Get User Info
FacebookHelper *fbHelper = [FacebookHelper sharedInstance];
