Not able to Login in Facebook using Parse Objective C - ios

Question

I am using Parse in my application. I am try to login with Facebook. But I have faced one strange issue. If I am login in Facebook account from my iPhone's settings, then I am getting following error.
Error Domain=com.facebook.sdk Code=2 "The operation couldn’t be completed. (com.facebook.sdk error 2.)" UserInfo=0x17560700 {com.facebook.sdk:ErrorLoginFailedReason=com.facebook.sdk:SystemLoginCancelled, com.facebook.sdk:ErrorInnerErrorKey=Error Domain=com.apple.accounts Code=7 "The operation couldn’t be completed. (com.apple.accounts error 7.)", com.facebook.sdk:ErrorSessionKey=<FBSession: 0x175227e0, state: FBSessionStateClosedLoginFailed, loginHandler: 0x0, appID: 638916992864352, urlSchemeSuffix: , tokenCachingStrategy:<PFFacebookTokenCachingStrategy: 0x175a9900>, expirationDate: (null), refreshDate: (null), attemptedRefreshDate: 0001-12-30 00:00:00 +0000, permissions:(null)>}
I am logout from iPhone's Settings->Facebook then its working fine.
I have done research on it, but not getting solutions.
Can anyone help to solve my issue ?
Thanks,

Try with below code..You need to give permissions in the code as in below code..
-(IBAction)facebookButtonAction:(id)sender
{
if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
{
self.accountStore = [[ACAccountStore alloc] init];
// Create an account type that ensures Twitter accounts are retrieved.
ACAccountType *accountType = [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
NSArray * permissions = [NSArray arrayWithObjects:#"email",#"user_location",#"user_birthday", nil];
NSDictionary * dict=[NSDictionary dictionaryWithObjectsAndKeys:#“xxxxxxxxxxxxxxx,ACFacebookAppIdKey,permissions,ACFacebookPermissionsKey,ACFacebookAudienceEveryone,ACFacebookAudienceKey, nil];
[self.accountStore requestAccessToAccountsWithType:accountType options:dict completion:^(BOOL granted, NSError *error) {
NSLog(#"-------------error =%#--------- check grant bol %d",error,granted);
if(granted ) {
NSArray *accountsArray = [self.accountStore accountsWithAccountType:accountType];
if ([accountsArray count] > 0)
{
ACAccount *fbAccount = [accountsArray objectAtIndex:0];
NSDictionary *tempDict = [[NSMutableDictionary alloc] initWithDictionary:[fbAccount dictionaryWithValuesForKeys:[NSArray arrayWithObject:#"properties"]]];
NSString *facebookname;
facebookname=#"Name not found";
facebookname = [[tempDict objectForKey:#"properties"] objectForKey:#"ACPropertyFullName"];
if ([facebookname isKindOfClass:[NSNull class]] || facebookname==NULL || [facebookname isEqualToString:#""] || [facebookname isEqualToString:#"(null)"])
{
facebookname = [[tempDict objectForKey:#"properties"] objectForKey:#"fullname"];
}
//if (SYSTEM_VERSION_LESS_THAN(#"7.0"))
{
}
NSString *facebookID = [NSString stringWithFormat:#"%#", [[fbAccount valueForKey:#"properties"] valueForKey:#"uid"]] ;
NSString *pictureURL=[NSString stringWithFormat:#"https://graph.facebook.com/%#/picture?type=large&return_ssl_resources=1",facebookID];
NSLog(#" check the properties %#",tempDict);
NSLog(#" name nemae %#",facebookname);
NSLog(#" facebookID %#",facebookID);
NSLog(#" image https://graph.facebook.com/%#/picture?type=large&return_ssl_resources=1",facebookID);
if ([facebookname isKindOfClass:[NSNull class]] || facebookname==NULL || [facebookname isEqualToString:#""] || [facebookname isEqualToString:#"(null)"])
{
UIAlertView *somethingerr=[[UIAlertView alloc]initWithTitle:#“App Name” message:#"Something went wrong with facebook login. Please send your console report to the developers." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[somethingerr show
];
[self hidespinner];
return;
}
}
else{
UIAlertView *alerts=[[UIAlertView alloc]initWithTitle:#"No facebok account" message:#"Please add or create an account in \"settings \" " delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil, nil];
[alerts show];
[self performSelector:#selector(hidespinner) withObject:nil afterDelay:0.1] ;
}
}
else{
switch ([error code])
{
case 0:
[self showErrorAlertWithMessage:#"Unknown error occured, try again later!"];
break;
case 1:
[self showErrorAlertWithMessage:#"Unknown error occured, try again later!"];
break;
case 3:
[self showErrorAlertWithMessage:#"Authentication failed, try again later!"];
break;
case 6:
[self showErrorAlertWithMessage:#"Facebook account does not exists. Please create it in Settings and come back!"];
break;
case 7:
[self showErrorAlertWithMessage:#"Permission request failed. You won't be able to share information to Facebook"];
break;
default:
[self performSelector:#selector(hidespinner) withObject:Nil afterDelay:0.1];
break;
}
}
}];
}
else{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"No Facebook Accounts" message:#"There are no Facebook accounts configured. You can add or create a Facebook account in Settings." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
[self performSelector:#selector(hidespinner) withObject:nil afterDelay:0.1] ;
}
}
