ios - Fetching basic information (id, first_name) from Facebook by using Social Framework - source code and screenshots attached

Question

For what would be a word game later I am trying to fetch very basic information about a player by using Social framework:

• id
• first_name
• gender
• location

(i.e. nothing sensitive like email and I don't use Facebook iOS SDK).

So in Xcode 5.0.2 I create a blank single view app for iPhone and add Social.framework to the Build phases tab.

Then I add the following code to the ViewController.m:

#import "ViewController.h"
#import <Social/Social.h>
#import <Accounts/Accounts.h>

#define FB_APP_ID @"432298283565593"
//#define FB_APP_ID @"262571703638"

@interface ViewController ()
@property (strong, nonatomic) ACAccountStore *accountStore;
@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];

    NSLog(@"Facebook is available: %d", [SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]);

    [self getMyDetails];
}

- (void) getMyDetails {
    if (!_accountStore) {
        _accountStore = [[ACAccountStore alloc] init];
    }

    ACAccountType *facebookAccountType = [_accountStore
                                        accountTypeWithAccountTypeIdentifier: ACAccountTypeIdentifierFacebook];
    NSDictionary *options = @{
                              ACFacebookAppIdKey: FB_APP_ID,
                              ACFacebookPermissionsKey: @[@"basic_info"]};

    [_accountStore requestAccessToAccountsWithType:facebookAccountType
                                           options:options
                                        completion:^(BOOL granted, NSError *error)
    {
        if (granted) {
            NSLog(@"Basic access granted");
        } else {
            NSLog(@"Basic access denied %@", error);
        }
    }];
}

@end

And create a new Facebook app for which I specify de.afarber.MyFacebook as the iOS Bundle ID:

Finally at Apple iTunes Connect I create a new App ID and then a new app (with a dummy icon and even 2 iPhone screenshots attached):

My Xcode Info tab and the rest of the source code are unchanged:

UPDATE 2:

I have updated the source code as suggested by helpful comments, thank you.

Also, I have another Facebook game, which works well (since 1-2 years) for an Adobe AIR desktop and mobile apps (but now I try to learn native iOS programming) and I have tried its id 262571703638 without success.

And I have added FacebookAppID to MyFacebook-Info.plist as suggested by Mohit10 (it seems to me that it is needed for Facebook SDK only, while I try to use Social Framework - but it can't hurt...)

Now I get the debugger output:

2013-12-31 11:08:07.584 MyFacebook[3009:70b] Facebook is available: 1
2013-12-31 11:08:07.964 MyFacebook[3009:3903] Basic access granted

I just need to figure out, how to fetch the id, first_name, gender, location now (and if basic_info is really needed for that)...

有了有用的评论（谢谢），我终于能够使用以下代码获取一些信息：

#import "ViewController.h"
#import <Social/Social.h>
#import <Accounts/Accounts.h>

#define FB_APP_ID @"432298283565593"
//#define FB_APP_ID @"262571703638"

@interface ViewController ()
@property (strong, nonatomic) ACAccount *facebookAccount;
@property (strong, nonatomic) ACAccountType *facebookAccountType;
@property (strong, nonatomic) ACAccountStore *accountStore;
@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];

    if (NO == [SLComposeViewController isAvailableForServiceType: SLServiceTypeFacebook]) {
        [self showAlert:@"There are no Facebook accounts configured. Please add or create a Facebook account in Settings."];
        return;
    }

    [self getMyDetails];
}

- (void) getMyDetails {
    if (! _accountStore) {
        _accountStore = [[ACAccountStore alloc] init];
    }

    if (! _facebookAccountType) {
        _facebookAccountType = [_accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
    }

    NSDictionary *options = @{ ACFacebookAppIdKey: FB_APP_ID };

    [_accountStore requestAccessToAccountsWithType: _facebookAccountType
                                           options: options
                                        completion: ^(BOOL granted, NSError *error) {
        if (granted) {
            NSArray *accounts = [_accountStore accountsWithAccountType:_facebookAccountType];
            _facebookAccount = [accounts lastObject];

            NSURL *url = [NSURL URLWithString:@"https://graph.facebook.com/me"];

            SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook
                                                    requestMethod:SLRequestMethodGET
                                                              URL:url
                                                       parameters:nil];
            request.account = _facebookAccount;

            [request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
                NSDictionary *responseDictionary = [NSJSONSerialization JSONObjectWithData:responseData
                                                                                   options:NSJSONReadingMutableContainers
                                                                                     error:nil];
                NSLog(@"id: %@", responseDictionary[@"id"]);
                NSLog(@"first_name: %@", responseDictionary[@"first_name"]);
                NSLog(@"last_name: %@", responseDictionary[@"last_name"]);
                NSLog(@"gender: %@", responseDictionary[@"gender"]);
                NSLog(@"city: %@", responseDictionary[@"location"][@"name"]);
            }];
        } else {
            [self showAlert:@"Facebook access for this app has been denied. Please edit Facebook permissions in Settings."];
        }
    }];
}

- (void) showAlert:(NSString*) msg {
    dispatch_async(dispatch_get_main_queue(), ^(void) {
        UIAlertView *alertView = [[UIAlertView alloc]
                                  initWithTitle:@"WARNING"
                                  message:msg
                                  delegate:nil
                                  cancelButtonTitle:@"OK"
                                  otherButtonTitles:nil];
        [alertView show];
    });
}

@end

这将打印我的数据：

id: 597287941
first_name: Alexander
last_name: Farber
gender: male
city: Bochum, Germany

如果您有任何改进建议，非常欢迎您。

Answer 2

由于您没有对 .plist 文件进行任何更改，因此您需要在 .plist 文件中添加您的 FacebookAppID。从中我认为这将有助于您获取用户详细信息，并且您也可以从您的设置中集成它。

Answer 3

您的代码有一些问题。

• ACAccountStore *accountStore超出范围，它应该是一个实例变量。
• 您不需要ACFacebookAudienceKey，那是用于发布的。
• 您不需要，ACFacebookPermissionsKey因为您想要的属性默认情况下可用

通过这些修复，您的代码仍然对我不起作用，尽管它确实适用于我的 App ID。我收到以下错误：

"The Facebook server could not fulfill this access request: Invalid application 432298283565593" UserInfo=0x1d5ab670 {NSLocalizedDescription=The Facebook server could not fulfill this access request: Invalid application 432298283565593}

您的应用的 Facebook 配置似乎有问题。

我能看到的唯一区别是我的应用程序是沙盒的，并且我使用我的开发人员帐户登录。祝你好运。

The answer is simple

in viewDidLoad() use:

accountStore= [[ACAccountStore alloc]init];
facebookAccountType= [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

NSDictionary *options= @{
ACFacebookAudienceKey: ACFacebookAudienceEveryone,
ACFacebookAppIdKey: @"<YOUR FACEBOOK APP ID>",
ACFacebookPermissionsKey: @[@"public_profile"]

                          };


[accountStore requestAccessToAccountsWithType:facebookAccountType options:options completion:^(BOOL granted, NSError *error) {

    if (granted) {
        NSLog(@"Permission has been granted to the app");
        NSArray *accounts= [accountStore accountsWithAccountType:facebookAccountType];
        facebookAccount= [accounts firstObject];
        [self performSelectorOnMainThread:@selector(facebookProfile) withObject:nil waitUntilDone:NO];

    } else {
        NSLog(@"Permission denied to the app");
    }
}];

/////And the function -(void)facebookProfile{

NSURL *url = [NSURL URLWithString:@"https://graph.facebook.com/me"];

//////Notice the params you need are added as dictionary ///Refer below for complete list ////https://developers.facebook.com/docs/graph-api/reference/user

NSDictionary *param=[NSDictionary dictionaryWithObjectsAndKeys:@"picture,id,name",@"fields", nil];

SLRequest *profileInfoRequest= [SLRequest requestForServiceType:SLServiceTypeFacebook requestMethod:SLRequestMethodGET URL:url parameters:param];
profileInfoRequest.account= facebookAccount;


[profileInfoRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
    NSLog(@"Facebook status code is : %ld", (long)[urlResponse statusCode]);

    if ([urlResponse statusCode]==200) {

        NSDictionary *dictionaryData= [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableLeaves error:&error];



    } else {

    }
}];
