Facebook登录状态检查问题 [英] Facebook Login Status Check Issue

问题描述

当用户打开Facebook设置视图时，如何识别当前的登录状态。如果记录，我如何检索用户的进一步信息。如生日，年龄，性别等。

When user open Facebook Setting View, how to identify the current log in status. And if it is logged, how can i retrieve the users' further information. such as birthday, age, gender, etc.

我写了这段代码，这是不行的。感谢提前。

i wrote this piece of code, which is not working. Thanks in advance.

- (void)viewDidLoad {
[super viewDidLoad];

if ([FBSDKAccessToken currentAccessToken]) {

    //Going to another ViewController, which include user's name,
    //age, photo and so on.
} else {
   FBSDKLoginButton *loginButton = [[FBSDKLoginButton alloc] init];

   loginButton.center = self.view.center;
   [self.view addSubview:loginButton];
}


}

推荐答案

if ([FBSDKAccessToken currentAccessToken]) {
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
  if (!error) {
     NSLog(@"fetched user:%@", result);
  }
 }];
}

尝试这个工作。
