【问题描述】：

我是在脸书上做的

[self vSuspendAndHaltThisThreadTillUnsuspendedWhileDoing:^
    [[NSOperationQueue mainQueue] addOperationWithBlock:^
        [self.ACAstore requestAccessToAccountsWithType:self.ACAccounts options:[self dicPostOptions] completion:^(BOOL granted, NSError *error) 
            self.bPermissionToAccessStoreGranted=granted;
            [self vContinue];
        ];
    ];
];

基本上我要求发布许可。我要做的是在再次询问之前检查是否已授予此类发布权限。

怎么做？

【参考方案1】：

检查可用权限：

      if(![postRequest.session.permissions containsObject:@"publish_actions"])

【讨论】：

什么是postRequest？从这里开始新程序。我正在使用社交框架。不是 facebook sdk。

【参考方案2】：

您可以使用带有me/permissions 的开放图形API 创建FBRequest。它会返回一个带有字典的响应，其中键是权限。

FBRequest *req = [FBRequest requestWithGraphpath:@"me/permissions" parameters:Nil HTTPMethod:@"GET"];
[req startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary* result,
NSError *error) 
      BOOL canPublish = FALSE;
      if (!error)
      
         FBGraphObject *data = [result objectForKey:@"data"];
         for(NSDictionary<FBGraphObject> *aKey in data) 
         
             canPublish = [[aKey objectForKey:@"publish_stream"] boolValue];
         
      
      else
      
         NSLog(@"%@", error);
      

      NSLog(@"%@", canPublish ? @"I have publish perms" : @"I don't have publish perms");
];

【讨论】：

但我使用的是社交框架。如果我使用社交框架，我需要做什么。

【参考方案3】：

试试这个 -

首先在您的应用委托中实现所有 facebook sdk 委托方法。

- (IBAction)loginWithFacebookButtonTapped:(id)sender

    IntubeAppDelegate *delegat = (IntubeAppDelegate*)[[UIApplication sharedApplication] delegate];
    [delegat doLoginAndSwitch];

现在，在您的 appDelegate 中 -

-(void) doLoginAndSwitch
      
    [self openSessionWithAllowLoginUI:YES];


- (BOOL)openSessionWithAllowLoginUI:(BOOL)allowLoginUI

    NSArray *permissions = [NSArray arrayWithObjects:@"email", nil]; 
    return [FBSession openActiveSessionWithPublishPermissions:permissions
                                      defaultAudience:FBSessionDefaultAudienceFriends
                                         allowLoginUI:YES
                                    completionHandler:^(FBSession *session, FBSessionState state, NSError *error) 

                                        [self sessionStateChanged:session
                                                            state:state
                                                            error:error];

                                    ];


-(BOOL)openSessionWithAllowPublishStreamPermission:(BOOL)allowLoginUI

    NSArray *permissions = [NSArray arrayWithObjects:@"publish_actions",@"publish_stream", nil];

[[FBSession activeSession] requestNewPublishPermissions:permissions defaultAudience:FBSessionDefaultAudienceEveryone completionHandler:^(FBSession *session, NSError *error)
];
    return YES;


- (void)sessionStateChanged:(FBSession *)session
              state:(FBSessionState)state
              error:(NSError *)error

    switch (state) 
        case FBSessionStateOpen:
            if(!error)
            
                //  NSLog(@"FBSessionStateOpen :- logged in");

                [self openSessionWithAllowPublishStreamPermission:YES];

               // Your code
            
         
 

我希望你现在能得到你想要的。 :)
