尝试通过 http://developers.facebook.com/docs/api 进行更深入的了解。以下是用户图片的链接：

http://graph.facebook.com/000000000/picture

其中 000000000 是登录用户的 ID。

更新，作者：Michael Gaylord：
您还可以将类型附加到请求中以获取不同大小的图像。因此，您的请求将类似于： http://graph.facebook.com/00000000/ picture?type=large 用于大图像。其他选项有小型、普通和方形。

我认为最简单的方法是这样的：

NSString *fbuid = @"1234567890";
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?", fbuid]];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *profilePic = [[[UIImage alloc] initWithData:data] autorelease];

I think the most simple way is this:

NSString *fbuid = @"1234567890";
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?", fbuid]];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *profilePic = [[[UIImage alloc] initWithData:data] autorelease];

这里使用这些委托方法来获取用户的图片。

当您创建会话时，您将获得名为 didLogin 的委托方法

- (void)session:(FBSession*)session didLogin:(FBUID)uid {

    isLoginSuccessful = TRUE;
    if(isLoginCanceled == FALSE) {
        [self fetchUserDetails];
    }
}

- (void)sessionDidNotLogin:(FBSession*)session {
    isLoginSuccessful = FALSE;
    isLoginCanceled = TRUE;
}

- (void)sessionDidLogout:(FBSession*)session {
    isLoginSuccessful = FALSE;
    isLoginCanceled = TRUE;
}

- (void)fetchUserDetails {

    NSString* fql = [NSString stringWithFormat:
                     @"select name,sex,pic from user where uid == %lld", _session.uid];

    NSDictionary* params = [NSDictionary dictionaryWithObject:fql forKey:@"query"];
    [[FBRequest requestWithDelegate:self] call:@"facebook.fql.query" params:params];
}

调用方法 requestWithDelegate 后，如果成功，您将在此方法中获得响应

- (void)request:(FBRequest*)request didLoad:(id)result {
    if ([request.method isEqualToString:@"facebook.fql.query"]) {
        NSArray* users = result;
        NSDictionary* user = [users objectAtIndex:0];
                NSLog(@"User Details %@",user);
        if(fbUserDetails == nil) {
            self.fbUserDetails = [[NSDictionary alloc] initWithDictionary:user];
        }
        if(isLoginSuccessful) {
            NSString *fbUid = [NSString stringWithFormat:@"%lld",_session.uid];
            self.FBUserID = fbUid;
            [_delegate loggedInFaceBookSuccessfully:fbUid];
        }

    }
}

您将获得可以在 GDB 中看到的 json 格式的所有详细信息

Here use these delegate methods to get the picture of user.

When you create session you will get the delegate method called didLogin

- (void)session:(FBSession*)session didLogin:(FBUID)uid {

    isLoginSuccessful = TRUE;
    if(isLoginCanceled == FALSE) {
        [self fetchUserDetails];
    }
}

- (void)sessionDidNotLogin:(FBSession*)session {
    isLoginSuccessful = FALSE;
    isLoginCanceled = TRUE;
}

- (void)sessionDidLogout:(FBSession*)session {
    isLoginSuccessful = FALSE;
    isLoginCanceled = TRUE;
}

- (void)fetchUserDetails {

    NSString* fql = [NSString stringWithFormat:
                     @"select name,sex,pic from user where uid == %lld", _session.uid];

    NSDictionary* params = [NSDictionary dictionaryWithObject:fql forKey:@"query"];
    [[FBRequest requestWithDelegate:self] call:@"facebook.fql.query" params:params];
}

after calling the method requestWithDelegate you'll get response in this method if succeed

- (void)request:(FBRequest*)request didLoad:(id)result {
    if ([request.method isEqualToString:@"facebook.fql.query"]) {
        NSArray* users = result;
        NSDictionary* user = [users objectAtIndex:0];
                NSLog(@"User Details %@",user);
        if(fbUserDetails == nil) {
            self.fbUserDetails = [[NSDictionary alloc] initWithDictionary:user];
        }
        if(isLoginSuccessful) {
            NSString *fbUid = [NSString stringWithFormat:@"%lld",_session.uid];
            self.FBUserID = fbUid;
            [_delegate loggedInFaceBookSuccessfully:fbUid];
        }

    }
}

You'll get all the details in json format you can see in GDB
