iOS Facebook获取用户的电子邮件 [英] iOS Facebook get user's e-mail

问题描述

我尝试了超过2000个东西来获取用户的电子邮件。我不能从Facebook SDK的图形API获得它。它不包含电子邮件属性。我也试图手动添加电子邮件属性到FB框架，没有发生任何事情。是否可以下载与iOS 7兼容的第一个FB SDK？它还有电子邮件属性，不是吗？或者有什么其他方式如何获得真实的电子邮件，我必须与他们一起工作。我不需要[e-mail]。

I tried over 2000 things to get the user's email. I can't get it from the Facebook SDK's graph API. It doesn't contain email property. I also tried to add manually the email property to the FB framework and nothing happened. Is it possible to download the first FB SDK which is compatible with iOS 7? Does it still have the email property, doesn't it? Or is there any other way how to get the REAL email, I must work with them. I don't need the [e-mail].

感谢任何建议。

推荐答案

我没有图形代码API，

I have not code for graph API,

但是新的facebook sdk版本3，我有代码。

but with new facebook sdk version 3, I have code for that.

-(void)openFbSession
{
    [[self appDelegate].session closeAndClearTokenInformation];

    NSArray *permissions =     [NSArray arrayWithObjects:@"email",@"user_location",@"user_birthday",@"user_hometown",nil];
    [self appDelegate].session = [[FBSession alloc] initWithPermissions:permissions];

    [[self appDelegate].session openWithCompletionHandler:^(FBSession *session,
                                                            FBSessionState status,
                                                            NSError *error) {
        if(!error)
        {
            NSLog(@"success");
            [self myFbInfo];
        }
        else
        {
            NSLog(@"failure");
        }

    }];
}

对于所有信息，myFbInfo方法是

and for all information, myFbInfo method is

-(void)myFbInfo
{
    [FBSession setActiveSession:[self appDelegate].session];

    [[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *FBuser, NSError *error) {
        if (error) {
            // Handle error
        }

        else {
            //NSString *userName = [FBuser name];
            //NSString *userImageURL = [NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?type=large", [FBuser id]];
            NSLog(@"Name : %@",[FBuser name]);
            NSLog(@"first name : %@",[FBuser first_name]);
            NSLog(@"Last name : %@",[FBuser last_name]);
            NSLog(@"ID : %@",[FBuser id]);
            NSLog(@"username : %@",[FBuser username]);
            NSLog(@"Email : %@",[FBuser objectForKey:@"email"]);

            NSLog(@"user all info : %@",FBuser);

              }
    }];

}

EDIT

在appdelegate.h

in appdelegate.h

@property (strong, nonatomic) FBSession *session;

在appdelegate.m

in appdelegate.m

- (BOOL)application: (UIApplication *)application openURL: (NSURL *)url sourceApplication: (NSString *)sourceApplication annotation: (id)annotation
{
    //NSLog(@"FB or Linkedin clicked");
    return [self.session handleOpenURL:url];
}


- (void)applicationDidBecomeActive:(UIApplication *)application
{
    [FBSession.activeSession handleDidBecomeActive];
}

- (void)applicationWillTerminate:(UIApplication *)application
{
    [self.session close];
}
