我已经阅读了很多关于从Facebook获取信息的教程,但到目前为止我都失败了.我只是想从Facebook获取用户名和个人资料图片.

- (IBAction)login:(id)sender {

   [FBSession openActiveSessionWithReadPermissions:@[@"email",@"user_location",@"user_birthday",@"user_hometown"]
                                   allowLoginUI:YES
                              completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {

   switch (state) {
      case FBSessionStateOpen:
         [[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
            if (error) {
               NSLog(@"error:%@",error);
            } else {
               // retrive user's details at here as shown below
               NSLog(@"FB user first name:%@",user.first_name);
               NSLog(@"FB user last name:%@",user.last_name);
               NSLog(@"FB user birthday:%@",user.birthday);
               NSLog(@"FB user location:%@",user.location);
               NSLog(@"FB user username:%@",user.username);
               NSLog(@"FB user gender:%@",[user objectForKey:@"gender"]);
               NSLog(@"email id:%@",[user objectForKey:@"email"]);
               NSLog(@"location:%@", [NSString stringWithFormat:@"Location: %@\n\n",
                                                                         user.location[@"name"]]);

             }
        }];
        break;
        case FBSessionStateClosed:
        case FBSessionStateClosedLoginFailed: …

我正在尝试检索配置文件图片的链接...到目前为止图形API调用:

[facebook requestWithGraphPath:@"me/picture" andDelegate:self];

将图像本身作为数据返回.当我打电话时:

[facebook requestWithGraphPath:@"me/picture" andDelegate:self];

我确实得到了一个包含每个链接的图片.反正有没有为个人资料图片获得某种类似的东西,至少只是链接...或者它不可能吗？如果有人已经通过这个,请告诉我.

干杯,

萨米.
