Facebook通過ios中的社交框架登錄

Question

我是iOS開發的新手。 我必須在我的iOS應用程序中集成Facebook登錄，因為用戶登錄它會獲取所有信息並將其導航到主屏幕。 我通過Facebook最新的SDK完成了這個，但我希望它通過社交框架完成。 我已經瀏覽了大量的在線資料，並且還找到了他們通過社交框架在Facebook頁面（Wall）上分享（發布）內容的示例，但不是Facebook登錄。 任何人請幫忙，讓我知道如果Facebook可以通過社交框架登錄，或者我必須堅持使用SDK。 提前致謝

Answer 1

導入社交和帳戶框架

將此代碼放在.m文件中

-(void)facebook
{
    self.accountStore = [[ACAccountStore alloc]init];
    ACAccountType *FBaccountType= [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

    NSString *key = @"451805654875339";
    NSDictionary *dictFB = [NSDictionary dictionaryWithObjectsAndKeys:key,ACFacebookAppIdKey,@[@"email"],ACFacebookPermissionsKey, nil];

    [self.accountStore requestAccessToAccountsWithType:FBaccountType options:dictFB completion:
     ^(BOOL granted, NSError *e) {
         if (granted)
         {
             NSArray *accounts = [self.accountStore accountsWithAccountType:FBaccountType];
             //it will always be the last object with single sign on
             self.facebookAccount = [accounts lastObject];


             ACAccountCredential *facebookCredential = [self.facebookAccount credential];
             NSString *accessToken = [facebookCredential oauthToken];
             NSLog(@"Facebook Access Token: %@", accessToken);


             NSLog(@"facebook account =%@",self.facebookAccount);

             [self get];

             [self getFBFriends];

             isFacebookAvailable = 1;
         } else
         {
             //Fail gracefully...
             NSLog(@"error getting permission yupeeeeeee %@",e);
             sleep(10);
             NSLog(@"awake from sleep");
             isFacebookAvailable = 0;

         }
     }];



}

-(void)checkfacebookstatus

        [self checkFacebook];
        isFacebookAvailable = 1;
    }
    else
    {
        printf("Get out from our game");
    }
}


-(void)get

            NSDictionary *list =[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];

            NSLog(@"Dictionary contains: %@", list );




            self.globalmailID   = [NSString stringWithFormat:@"%@",[list objectForKey:@"email"]];
            NSLog(@"global mail ID : %@",globalmailID);


            fbname = [NSString stringWithFormat:@"%@",[list objectForKey:@"name"]];
            NSLog(@"faceboooookkkk name %@",fbname);




            if([list objectForKey:@"error"]!=nil)
            {
                [self attemptRenewCredentials];
            }
            dispatch_async(dispatch_get_main_queue(),^{

            });
        }
        else
        {
            //handle error gracefully
            NSLog(@"error from get%@",error);
            //attempt to revalidate credentials
        }

    }];

    self.accountStore = [[ACAccountStore alloc]init];
    ACAccountType *FBaccountType= [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

    NSString *key = @"451805654875339";

    [self.accountStore requestAccessToAccountsWithType:FBaccountType options:dictFB completion:
     ^(BOOL granted, NSError *e) {}];

}




-(void)accountChanged:(NSNotification *)notification
{
    [self attemptRenewCredentials];
}

-(void)attemptRenewCredentials
{
    [self.accountStore renewCredentialsForAccount:(ACAccount *)self.facebookAccount completion:^(ACAccountCredentialRenewResult renewResult, NSError *error){

                case ACAccountCredentialRenewResultRejected:
                    NSLog(@"User declined permission");
                    break;
                case ACAccountCredentialRenewResultFailed:
                    NSLog(@"non-user-initiated cancel, you may attempt to retry");
                    break;
                default:
                    break;
            }

        }
        else{
            //handle error gracefully
            NSLog(@"error from renew credentials%@",error);
        }
    }];
}

Swift 3版解決方案@reena

@IBAction func loginButtonPressed(_ sender: UIButton) {

    var facebookAccount: ACAccount?
    let options:[String : Any] = [ACFacebookAppIdKey: "YOUR_FACEBOOK_API_KEY", ACFacebookPermissionsKey: ["email"],ACFacebookAudienceKey:ACFacebookAudienceFriends]

    let accountStore = ACAccountStore()

    let facebookAccountType = accountStore.accountType(withAccountTypeIdentifier: ACAccountTypeIdentifierFacebook)

    accountStore.requestAccessToAccounts(with: facebookAccountType, options: options) { (granted:Bool, error:Error?) in
        if granted{
            let accounts = accountStore.accounts(with: facebookAccountType)
            facebookAccount = accounts?.last as? ACAccount

            let dict:NSDictionary = facebookAccount!.dictionaryWithValues(forKeys: ["properties"]) as NSDictionary
            let properties:NSDictionary = dict["properties"] as! NSDictionary

            print("facebook Response is-->:%@",properties)
        }
        else {
            if let err = error as? NSError, err.code == Int(ACErrorAccountNotFound.rawValue) {
                DispatchQueue.main.async {
                    self.displayAlert("There is no Facebook accounts configured. you can add or created a Facebook account in your settings.")

Facebook使用帳戶和社交框架登錄（快速）

var facebookAccount: ACAccount?

        let options: [NSObject : AnyObject] = [ACFacebookAppIdKey: "YOUR_FACEBOOK_API_KEY", ACFacebookPermissionsKey: ["publish_stream","publish_actions"],ACFacebookAudienceKey:ACFacebookAudienceFriends]
        let accountStore = ACAccountStore()
        let facebookAccountType = accountStore.accountTypeWithAccountTypeIdentifier(ACAccountTypeIdentifierFacebook)

            accountStore.requestAccessToAccountsWithType(facebookAccountType, options: options) { (granted, error) -> Void in
                if granted
                {
                    let accounts = accountStore.accountsWithAccountType(facebookAccountType)
                    self.facebookAccount = accounts.last as? ACAccount
                    let accountsArray=accountStore.accountsWithAccountType(facebookAccountType) as NSArray

                    self.facebookAccount=accountsArray.lastObject as? ACAccount
                    var dict:NSDictionary
                    dict=NSDictionary()

                    dict=self.facebookAccount!.dictionaryWithValuesForKeys(["properties"])
                    let properties:NSDictionary=dict["properties"] as! NSDictionary
                    print("facebook Response is-->:%@",properties)
