Facebook权限警报显示重复文本

Question

我从具有基本个人资料和朋友列表权限的设置中获取FB用户列表。它工作正常。但警报显示文字如下：

“应用名称”希望代表您访问您的基本个人资料信息和朋友列表。此外，它还想访问您的基本个人资料信息和朋友列表。“

代码有什么问题吗？

    ACAccountType *FBaccountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

NSString *key = FACEBOOK_APP_ID;

NSMutableDictionary *dictFB  = [NSMutableDictionary dictionaryWithObjectsAndKeys:key,ACFacebookAppIdKey,@[@"email", @"user_friends", @"public_profile"],ACFacebookPermissionsKey, nil];

[accountStore requestAccessToAccountsWithType:FBaccountType options:dictFB completion:
 ^(BOOL granted, NSError *e)
 {
     if (granted)
     {
         self.facebookAcconts = [[accountStore accountsWithAccountType:FBaccountType]mutableCopy];

         if (self.facebookAcconts.count > 0)
         {
             id account = [self.facebookAcconts objectAtIndex:0];
             if (account)
             {
                 [accountStore renewCredentialsForAccount:account completion:^(ACAccountCredentialRenewResult renewResult, NSError *error) {
                     if(!error)
                     {
                         switch (renewResult) {
                             case ACAccountCredentialRenewResultRenewed:

                                 break;
                             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);
                     }
                 }];
             }
         }
     }
 }];
