Getting user's Personal info from Facebook in iOS
提问by Simer Sarao
I am quite new to objective-C and iPhone Development environment.
我对objective-C和iPhone开发环境很陌生。
I am implementing Facebook login in my app to get User's name, Email and profile Picture. I have successfully implemented login Part and have received name and User ID of the person.
我正在我的应用程序中实现 Facebook 登录以获取用户的姓名、电子邮件和个人资料图片。我已经成功实现了登录部分，并收到了该人的姓名和用户 ID。
Now i want to get User's Email and Profile Picture from Facebook.But i am not having any Idea how to get it.I am using Facebook IOS SDK v4.0.
现在我想从 Facebook 获取用户的电子邮件和个人资料图片。但我不知道如何获取它。我正在使用 Facebook IOS SDK v4.0。
How can i fetch User's Profile picture and Email Id from Facebook when i am having User ID?
当我有用户 ID 时，如何从 Facebook 获取用户的个人资料图片和电子邮件 ID？
回答by Dheeraj Singh
To get user Email ID you must ask permission for emailwhile logging.
要获取用户电子邮件 ID，您必须在登录时请求电子邮件许可。
FBSDKLoginButton *loginView = [[FBSDKLoginButton alloc] init];
loginView.readPermissions = @[@"email"];
loginView.frame = CGRectMake(100, 150, 100, 40);
[self.view addSubview:loginView];
You can get user email Id in New SDK using GraphPath.
您可以使用 GraphPath 在新 SDK 中获取用户电子邮件 ID。
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if (!error) {
NSLog(@"fetched user:%@ and Email : %@", result,result[@"email"]);
}
}];
}
result would get you all the user Details and result[@"email"] would get you the email for logged in user.
result 将为您提供所有用户详细信息，而 result[@"email"] 将为您提供登录用户的电子邮件。
To get Profile picture you can use
要获取个人资料图片，您可以使用
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?type=normal",result[@"id"]]];
NSData *data = [NSData dataWithContentsOfURL:url];
_imageView.image = [UIImage imageWithData:data];
or u can also use FBSDKProfilePictureView to get profile Picture by passing user profile Id:
或者您也可以使用 FBSDKProfilePictureView 通过传递用户个人资料 ID 来获取个人资料图片：
FBSDKProfilePictureView *profilePictureview = [[FBSDKProfilePictureView alloc]initWithFrame:_imageView.frame];
[profilePictureview setProfileID:result[@"id"]];
[self.view addSubview:profilePictureview];
Refer to :https://developers.facebook.com/docs/facebook-login/ios/v2.3#profile_picture_view
参考：https: //developers.facebook.com/docs/facebook-login/ios/v2.3#profile_picture_view
or u can also get both by passing as parameters
或者你也可以通过作为参数传递
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me"
parameters:@{@"fields": @"picture, email"}]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if (!error) {
NSString *pictureURL = [NSString stringWithFormat:@"%@",[result objectForKey:@"picture"]];
NSLog(@"email is %@", [result objectForKey:@"email"]);
NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:pictureURL]];
_imageView.image = [UIImage imageWithData:data];
}
else{
NSLog(@"%@", [error localizedDescription]);
}
}];

Sorry for this messy answer, this is my first answer ever. You can use FBSDK Graph request to fetch user's all profile infos and FBSDKProfilePictureView class to fetch user's Profile Picture easily.This code is for manually Facebook login UI.
抱歉这个乱七八糟的答案，这是我有史以来的第一个答案。您可以使用 FBSDK Graph 请求来获取用户的所有个人资料信息和 FBSDKProfilePictureView 类来轻松获取用户的个人资料图片。此代码用于手动 Facebook 登录 UI。
Firstly, you must put this code where login process start:
首先，您必须将此代码放在登录过程开始的位置：
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login logInWithReadPermissions:@[@"public_profile", @"email"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
if (error)
{
// There is an error here.
}
else
{
if(result.token) // This means if There is current access token.
{
// Token created successfully and you are ready to get profile info
[self getFacebookProfileInfo];
}
}
}];
And If login is successfull, implement this method to get user's public profile;
并且如果登录成功，则执行此方法以获取用户的公开资料；
-(void)getFacebookProfileInfos {
FBSDKGraphRequest *requestMe = [[FBSDKGraphRequest alloc]initWithGraphPath:@"me" parameters:nil];
FBSDKGraphRequestConnection *connection = [[FBSDKGraphRequestConnection alloc] init];
[connection addRequest:requestMe completionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if(result)
{
if ([result objectForKey:@"email"]) {
NSLog(@"Email: %@",[result objectForKey:@"email"]);
}
if ([result objectForKey:@"first_name"]) {
NSLog(@"First Name : %@",[result objectForKey:@"first_name"]);
}
if ([result objectForKey:@"id"]) {
NSLog(@"User id : %@",[result objectForKey:@"id"]);
}
}
}];
[connection start];
Get current logged in user's profile picture:
获取当前登录用户的个人资料图片：
FBSDKProfilePictureView *pictureView=[[FBSDKProfilePictureView alloc]init];
[pictureView setProfileID:@"user_id"];
[pictureView setPictureMode:FBSDKProfilePictureModeSquare];
[self.view addSubview:pictureView];
You must add refreshing code to your viewDidLoad method:
您必须向 viewDidLoad 方法添加刷新代码：
[FBSDKProfile enableUpdatesOnAccessTokenChange:YES];
