在我的iPhone应用程序上从Facebook获取朋友信息

Question

我正在为iPhone开发一个使用facebook的应用程序。我需要获取我的数据（当前用户的数据）。

我确信我进行了正确的登录并获得了适当的权限。

现在，

我想要一个带有数据的NSArray，并用NSLog打印这个数据。

我为友谊赛做了这个，我没有问题：

-(IBAction)friendsInfo:(id)sender{
   //  get the logged-in user's friends
   [facebook requestWithGraphPath:@"me/friends" andDelegate:self];
  }
- (void)request:(FBRequest *)request didLoad:(id)result {
    //ok so it's a dictionary with one element (key="data"), which is an array of dictionaries, each with "name" and "id" keys
    items = [(NSDictionary *)result objectForKey:@"data"];
    for (int i=0; i<[items count]; i++) {
        NSDictionary *friend = [items objectAtIndex:i];
        long long fbid = [[friend objectForKey:@"id"]longLongValue];
        NSString *name = [friend objectForKey:@"name"];
        NSLog(@"id: %lld - Name: %@", fbid, name);
    }
}

但对于我的信息，同样的方法不起作用：

-(IBAction)myInfo:(id)sender{
    // get information about the currently logged in user
    [facebook requestWithGraphPath:@"me" andDelegate:self];
     }

有人能帮我吗？

Answer 1

使用此函数获取您的faceBook信息（已登录用户信息）

- (void)fetchUserDetails {
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               @"SELECT uid, name, pic FROM user WHERE uid=me()", @"query",nil];
[fb requestWithMethodName:@"fql.query"
                                 andParams:params
                             andHttpMethod:@"POST"
                               andDelegate:self];

}

          -(void)addList:(FBSession *)session {
    NSString* fql = [NSString stringWithFormat:
                     @"select uid from user where uid == %lld",    session.uid];
    NSDictionary* params = [NSDictionary dictionaryWithObject:fql forKey:@"query"];
    sessionView = session;
    [[FBRequest requestWithDelegate:self] call:@"facebook.friends.get" params:params];

}
         - (void)request:(FBRequest*)request didLoad:(id)result {
    if(myList==nil) {
        NSArray* users = result;
        myList =[[NSArray alloc] initWithArray: users];
        for(NSInteger i=0;i<[users count];i++) {
            NSDictionary* user = [users objectAtIndex:i];
            NSString* uid = [user objectForKey:@"uid"];
            NSString* fql = [NSString stringWithFormat:
                         @"select name from user where uid == %@", uid];
            NSDictionary* params = [NSDictionary dictionaryWithObject:fql          forKey:@"query"];
            [[FBRequest requestWithDelegate:self] call:@"facebook.fql.query"     params:params];
        }
    }
    else {
        NSArray* users = result;
        NSDictionary* user = [users objectAtIndex:0];
        NSString* name = [user objectForKey:@"name"];
        txtView.text=[NSString     localizedStringWithFormat:@"%@%@,n",txtView.text,name];
    }
}

-(IBAction)getMeFriendsButtonPressed:(id)sender {
    FbGraphResponse *fb_graph_response = [fbGraph doGraphGet:@"me/friends" withGetVars:nil];
    NSLog(@"getMeFriendsButtonPressed:  %@", fb_graph_response.htmlResponse);
    NSDictionary *DictTmp = [fb_graph_response.htmlResponse JSONValue];
    NSMutableArray *myFriendList=[[DictTmp objectForKey:@"data"];
}

NSString* fql = [NSString stringWithFormat:@"select uid,name from user where uid == %lld", session.uid];
NSDictionary* params = [NSDictionary dictionaryWithObject:fql forKey:@"query"];
[[FBRequest requestWithDelegate:self] call:@"facebook.fql.query" params:params];
[[FBRequest requestWithDelegate:self] call:@"facebook.friends.get" params:params];
