Facebook通过ios中的社交框架登录 [英] Facebook login via social framework in ios

问题描述

我是iOS开发的新手。我必须在我的iOS应用程序中集成Facebook登录，因为用户登录它会获取所有信息并将其导航到主屏幕。我通过Facebook最新的SDK完成了这个，但我希望它通过社交框架完成。我已经浏览了很多在线资料，并且还找到了他们通过社交框架在Facebook页面（Wall）上分享（发布）内容的示例，但不是Facebook登录。任何人请帮助，让我知道如果Facebook可以通过社交框架登录，或者我必须坚持使用SDK。在此先感谢

I'm new with iOS development. I have to integrate Facebook login in my iOS app, as user logs in it fetches all the info and navigates it to home screen. I have done this via Facebook latest SDK but I want it to be done via social framework. I have gone through lots of online stuff and also have found examples where they are sharing(posting) content on Facebook page(Wall) via social framework but not Facebook login exactly. Anyone please help, let me know if Facebook login is possible via social framework or i have to stick to SDK. Thanks in Advance

导入社交和帐户框架

把这个放.m文件中的代码

put this code in your .m file

-(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);
