使用facebook iOS 6登录

如何在iOS应用程序中使用facebook实现登录

我听说facebook集成在iOS 6中

使用Facebook登录后，我可以获得用户名吗

是否有任何示例教程显示了这一点

提前感谢。

Viewcontroller.h

#import <Accounts/ACAccountStore.h>
#import <Accounts/ACAccount.h>
#import <Social/Social.h>
#import <Accounts/ACAccountType.h>
#import <Accounts/ACAccountCredential.h>

@property (strong, nonatomic) ACAccountStore *accountStore;
@property (strong, nonatomic) ACAccount *facebookAccount;

如果您有任何问题，请告诉我。这对您有用吗？显示未声明标识符的使用

dictFB

此处

[self.accountStore requestAccessToAccountsWithType:FBaccountType选项：dictFB completion:^（BOOL已授予，NSError*e）{

@Krunal，我编辑了我的代码。查看并回复我。你必须在facebook开发者网站上制作一个应用程序。当我点击按钮时，它会显示我的应用程序想要访问

基本配置文件和朋友列表你想允许访问吗？？？

我点击了“允许”，但之后什么也没有发生。

-(void)getUserinfo{

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

    NSArray *accounts = [self.accountStore accountsWithAccountType:FBaccountType];
       self.facebookAccount = [accounts lastObject];

    if (![SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]){
        UIAlertView *alt=[[UIAlertView alloc]initWithTitle:@"Error!" message:@"No Facebook Account is set in settings." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
        [alt performSelectorOnMainThread:@selector(show) withObject:nil waitUntilDone:YES];
        [alt release]; 
        return;
    }


  // **********  changed *****
              NSString *key = @"111111111111"; // // Create a Facebook app on developers.facebook.com & get the Key 
    NSDictionary *dictFB = [NSDictionary dictionaryWithObjectsAndKeys:key,ACFacebookAppIdKey,@[@"email"],ACFacebookPermissionsKey, nil];

 // **********  changed *****


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

              NSArray *accounts = [self.accountStore accountsWithAccountType:FBaccountType];
             NSLog(@"%@",accounts);
             //it will always be the last object with single sign on
             self.facebookAccount = [accounts lastObject];
          NSLog(@"%@",accounts); // Check HERE Which Property you need



 NSString *fab_name=[NSString stringWithFormat:@"%@",[[accounts valueForKey:@"properties"]valueForKey:@"ACUIDisplayUsername"]];
     }
 }];
