使用故事板登录iOS 6应用程序

Question

我是iOS新手，尤其是Facebook等社交媒体框架。我试图理解 facebook 提供的教程，但他们以 xib 格式做到了，我似乎迷路了。我尝试使用故事板构建应用程序。请为我提供一些链接，以使用故事板创建iOS 6 facebook登录应用程序。谢谢

首先，您需要将社交和帐户框架导入到您的应用程序中。 在故事板上添加按钮。 并将 SlComposerCode 写入该按钮。

 -(Void)BtnClicked:(id)sender
    {
    ACAccountType *facebookTypeAccount = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

        [accountStore requestAccessToAccountsWithType:facebookTypeAccount
                                               options:@{ACFacebookAppIdKey: @"131740927031850", ACFacebookPermissionsKey: @[@"email"]}
                                            completion:^(BOOL granted, NSError *error) {
                                                if(granted){
                                                    NSArray *accounts = [accountStore accountsWithAccountType:facebookTypeAccount];
                                                    _facebookAccount = [accounts lastObject];
                                                    ACAccountCredential *fbCredential = [_facebookAccount credential];
                                                    accessToken = [fbCredential oauthToken];
                                                    NSLog(@"Facebook Access Token: %@", accessToken);
                                                    NSLog(@"Success");
                                                    [self facebook];
                                                }else{
                                                    NSLog(@"Fail");
                                                    NSLog(@"Error: %@", error);
                                                }
                                            }];
        if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
        {
            SLComposeViewController *tweetSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
            [tweetSheet setInitialText:@"posting from my own app! :)"];
            [tweetSheet addURL:[NSURL URLWithString:@"www.google.com"]];
            [tweetSheet addImage:[UIImage imageNamed:@"57.png"]];


            [self presentViewController:tweetSheet animated:YES completion:nil];

        }
        else
        {
            UIAlertView *alertView = [[UIAlertView alloc]
                                      initWithTitle:@"Sorry"
                                      message:@"You can't send a tweet right now, make sure your device has an internet connection and you have at least one Twitter account setup"
                                      delegate:self
                                      cancelButtonTitle:@"OK"
                                      otherButtonTitles:nil];
            [alertView show];
        }
    }
    - (void)facebook
    {
        NSURL *meurl = [NSURL URLWithString:@"https://graph.facebook.com/me"];
        NSLog(@"URl:-%@",meurl);
        SLRequest *merequest = [SLRequest requestForServiceType:SLServiceTypeFacebook
                                                  requestMethod:SLRequestMethodGET
                                                            URL:meurl
                                                     parameters:nil];
        merequest.account = _facebookAccount;
        [merequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
            NSString *meDataString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
            NSLog(@"Parsed Data:-%@", meDataString);
        }];
    }

试试这段代码。
