iPhone AppのFacebookのユーザー名を取得する

Question

誰かが私のアプリを通してFacebookにログインしたら、どのようにしてユーザー名を取得できますか？

私は次を使用しています： - FBConnect API。

私Controller.mは

#import "FacebookPOCViewController.h" 

@implementation FacebookPOCViewController 
@synthesize session = _session; 
@synthesize logoutButton = _logoutButton; 
@synthesize loginDialog = _loginDialog; 
@synthesize facebookName = _facebookName; 


- (void)viewDidLoad { 

    //PayTai Facebook App 
    static NSString* kApiKey = @"230600000000"; 
    static NSString* kApiSecret = @"----------------------"; 
    _session = [[FBSession sessionForApplication:kApiKey secret:kApiSecret delegate:self] retain]; 

    // Load a previous session from disk if available. Note this will call session:didLogin if a valid session exists. 
    [_session resume]; 

    [super viewDidLoad]; 
} 
- (IBAction)loginTapped:(id)sender { 
    //_posting = YES; 
    // If we're not logged in, log in first... 
    if (![_session isConnected]) { 
     self.loginDialog = nil; 
     _loginDialog = [[FBLoginDialog alloc] init];  
     [_loginDialog show];  
    } 
    // If we have a session and a name, post to the wall! 
    else if (_facebookName != nil) { 
     //[self postToWall]; 
     printf("Session"); 
    } 
    // Otherwise, we don't have a name yet, just wait for that to come through. 
} 

- (IBAction)logoutButtonTapped:(id)sender { 
    [_session logout]; 
} 
#pragma mark FBSessionDelegate methods 

- (void)session:(FBSession*)session didLogin:(FBUID)uid { 
    [self getFacebookName]; 
} 

- (void)session:(FBSession*)session willLogout:(FBUID)uid { 
    _logoutButton.hidden = YES; 
    _facebookName = nil; 
} 




    pragma mark Get Facebook Name Helper 

- (void)getFacebookName { 
    NSString* fql = [NSString stringWithFormat:@"select uid,name from user where uid == %lld", _session.uid]; 
    //NSLog(@"%@",_session.uid); 
    NSDictionary* params = [NSDictionary dictionaryWithObject:fql forKey:@"query"]; 
    [[FBRequest requestWithDelegate:self] call:@"facebook.fql.query" params:params]; 
} 

#pragma mark FBRequestDelegate methods 

- (void)request:(FBRequest*)request didLoad:(id)result { 
    if ([request.method isEqualToString:@"facebook.fql.query"]) { 
     NSArray* users = result; 
     NSDictionary* user = [users objectAtIndex:0]; 
     NSString* name = [user objectForKey:@"name"]; 
     self.facebookName = name;  
     _logoutButton.hidden = NO; 
     [_logoutButton setTitle:[NSString stringWithFormat:@"Logout as %@", name] forState:UIControlStateNormal]; 
     //if (_posting) { 
//   [self postToWall]; 
//   _posting = NO; 
//  } 
    } 
}

はこれを見てください[ファイル] - 。 GRAPH APIを使用すると、ユーザーのほぼすべての情報を取得できます。

http://developers.facebook.com/docs/reference/api/user/

例

/** 
* Request the facebook name for the user 
* Response will be obtained on delegate 
*/ 
- (void) getFacebookName { 

    [facebook requestWithGraphPath:@"me?fields=id,name" andDelegate:self]; 
} 

#pragma mark - FBRequestDelegate methods 

- (void)request:(FBRequest *)request didLoad:(id)result { 

    NSLog(@"Result: %@", result); 
    NSDictionary *userInfo = (NSDictionary *)result; 
    userName = [userInfo objectForKey:@"name"]; 
    fb_id = [userInfo objectForKey:@"id"]; 
    }
