iPhone Facebook SDK錯誤

Question

我想弄清楚這個錯誤的含義是什麼...

我想通過Facebook SDK獲取用戶信息。所有我需要的是他們的電子郵件和姓名

Error Domain=facebookErrDomain Code=10000 "The operation couldn’t be completed. (facebookErrDomain error 10000.)" UserInfo=0xde94ad0 {error=<CFBasicHash 0xde7d100 [0x3f616650]>{type = mutable dict, count = 3, 
entries => 
    2 : <CFString 0xde722a0 [0x3f616650]>{contents = "type"} = <CFString 0xdeba1a0 [0x3f616650]>{contents = "OAuthException"} 
    3 : <CFString 0xde6ba20 [0x3f616650]>{contents = "message"} = <CFString 0xdeb12a0 [0x3f616650]>{contents = "An active access token must be used to query information about the current user."} 
    6 : <CFString 0xde74c40 [0x3f616650]>{contents = "code"} = 2500 
} 
} 

我（在我的viewDidLoad以下）基本代碼...

facebook = [[Facebook alloc] initWithAppId:@"random#123456" andDelegate:self]; 

    [self login]; 

（下面我登錄方法）

- (void) login { 
    NSArray *permissionsArray = [NSArray arrayWithObjects:@"email", nil]; 
    [facebook authorize:permissionsArray]; 
} 

（和我的Facebook請求方法...）

- (void)request:(FBRequest *)request didLoad:(id)result { 
    NSLog(@"Inside didLoad"); 
    if ([result isKindOfClass:[NSArray class]]) { 
     result = [result objectAtIndex:0]; 
    } 
    // When we ask for user infor this will happen. 
    if ([result isKindOfClass:[NSDictionary class]]){ 
     //NSDictionary *hash = result; 
     NSLog(@"Name: %@", [result objectForKey:@"name"]); 
    } 
    if ([result isKindOfClass:[NSData class]]) 
    { 
     NSLog(@"Profile Picture"); 
     //[profilePicture release]; 
     //profilePicture = [[UIImage alloc] initWithData: result]; 
    } 
    NSLog(@"request returns %@",result); 
    //if ([result objectForKey:@"owner"]) {} 

}; 

- (void)request:(FBRequest *)request didFailWithError:(NSError *)error{ 
    NSLog(@"%@",error); 
} 

我真的很困惑，爲什麼我得到一個錯誤，我需要更改或添加以修復它...

任何想法？

編輯：我的請求代碼:::

- (IBAction)requestFBFriends:(id)sender { 
    NSLog(@"HERE"); 
    [facebook requestWithGraphPath:@"me/friends" andDelegate:self]; 
}

下面是如何獲取名稱和電子郵件... 我沒有測試它，所以如果它不工作只是告訴我會發現問題。

發送請求的方法需要，如果你沒有一個有效的訪問令牌

    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
    if ([defaults objectForKey:@"FBAccessTokenKey"] && [defaults objectForKey:@"FBExpirationDateKey"]) {

     self.facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"]; 
    } 
    if (![self.facebook isSessionValid]) { 
     NSLog(@"auth"); 
     [self.facebook authorize:[NSArray arrayWithObject:@"email"]]; 
    } else {

如果您運行的模擬器/設備上的應用嘗試清洗構建和全新安裝應用程序。目前的錯誤可能是由於不活動/撤銷的訪問令牌，它不再有效訪問用戶數據。 希望它有幫助！
