如何在没有Facebook sdk的情况下在iOS >= 6中进行Facebook登录

Question

如何在没有Facebook sdk的情况下在iOS中登录(我支持iOS6和iOS7)。我的应用程序使用Facebook登录，用户可以在Facebook上分享帖子。此外，我需要发送Facebook的用户id和身份验证令牌到我的服务器。

早些时候我支持Xcode5，但现在我的iOS目标是使用Xcode5的>= iOS6。

为此，我使用了Facebook SDK 3.11。通过研究，我了解到我们可以使用SLComposeViewController，UIActivityViewController或SLRequest来分享帖子。这将解决我的共享问题，但如何做Facebook登录和获得身份验证令牌？

我尝试了Facebook登录的SLRequest和分享的SLComposeViewController，那么这是一个好的解决方案吗？(在这里，我想要显示Facebook本地共享对话框。所以我没有使用SLRequest来分享帖子，因为我们必须为它创建视图。)

我推荐了this link。这是前进的最佳解决方案吗？

只有您的部署目标6 -you在-if中设置了捆绑包id，然后develelopers.facebook.com -you才在您的plist中设置了fb_app_id

在没有facebook sdk的情况下这样做，

#import <Social/Social.h>
#import <Accounts/Accounts.h>
#define FB_APP_ID @"45666675444" // ur id here
@interface OGShareViewController ()
@property (strong, nonatomic) ACAccountStore *accountStore;
@property (strong, nonatomic) ACAccount *facebookAccount;
@property (strong, nonatomic) ACAccountType *facebookAccountType;
@end

-(void)viewDidLoad
{
[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];
