FB integration in ios app issues - iphone

Question

I have integrated the facebook in my ios app and it is working nice.
But when i stored my FB credentials in setting it is not working.
It goes in following state
- (void)sessionStateChanged:(FBSession *)session
state:(FBSessionState) state
error:(NSError *)error
{
switch (state) {
case FBSessionStateOpen:
NSLog(#"case open session");
// if([sharePref returnFbName].length==0)
[self listFriendsFB];
break;
case FBSessionStateClosed:
NSLog(#"case FBSessionStateClosed session");
case FBSessionStateClosedLoginFailed:
// Once the user has logged in, we want them to
// be looking at the root view.
//[viewController popToRootViewControllerAnimated:NO];
[FBSession.activeSession closeAndClearTokenInformation];
NSLog(#"case close or fail session");
break;
default:
break;
}
It goes in FBSessionStateClosedLoginFailed , and error occurs.
And if I delete my account from phone setting it working fine i.e the session opens and it is logged in correctly.
Here is my code
- (void)openSession
{
//[self syncFacebookAccount];
NSArray *permissions=[[NSArray alloc]initWithObjects:#"email,publish_actions",nil];
dispatch_async(dispatch_get_main_queue(), ^{
[FBSession openActiveSessionWithReadPermissions:permissions
allowLoginUI:YES
completionHandler:
^(FBSession *session,
FBSessionState state, NSError *error) {
NSLog(#"fb open session");
[self sessionStateChanged:session state:state error:error];
}];
});
}
- (void)sessionStateChanged:(FBSession *)session
state:(FBSessionState) state
error:(NSError *)error
{
switch (state) {
case FBSessionStateOpen:
NSLog(#"case open session");
// if([sharePref returnFbName].length==0)
[self fourthViewInitialization];
[self getFacebookInfo];
break;
case FBSessionStateClosed:
NSLog(#"case FBSessionStateClosed session");
case FBSessionStateClosedLoginFailed:
// Once the user has logged in, we want them to
// be looking at the root view.
//[viewController popToRootViewControllerAnimated:NO];
[FBSession.activeSession closeAndClearTokenInformation];
NSLog(#"case close or fail session");
break;
default:
break;
}
if (error) {
UIAlertView *alertView = [[UIAlertView alloc]
initWithTitle:AlertTitle
message:#"We are currently facing facebook connectivity issues. Please try again later!"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
NSLog(#"error facebook : %#",error);
[alertView show];
[self hideActivityIndicator];
}
}
#pragma facebook methods
-(void)getFacebookInfo
{
// [NSThread detachNewThreadSelector:#selector(startLoader) toTarget:self withObject:nil];
NSString *query =[NSString stringWithFormat:#"Select name,uid,pic_square from user where uid=me()"];
// Set up the query parameter
my_info=[[NSMutableDictionary alloc]init];
my_info_array=[[NSMutableArray alloc ]init];
NSDictionary *queryParam =
[NSDictionary dictionaryWithObjectsAndKeys:query, #"q", nil];
// Make the API request that uses FQL
[FBRequestConnection startWithGraphPath:#"/fql"
parameters:queryParam
HTTPMethod:#"GET"
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error) {
if (error) {
NSLog(#"Error: %#", [error localizedDescription]);
[self hideActivityIndicator];
} else {
// NSLog(#"Result: %#", result);
// [self hideActivityIndicator];
my_info_array=(NSMutableArray *)[result objectForKey:#"data"];
my_info=[my_info_array objectAtIndex:0];
//NSLog(#"my info array %#",my_info_array);
NSLog(#"my info from fb %#",my_info);
//return my_info;
[firstView removeFromSuperview];
[self.view addSubview:fourthView];
displayNameLabel.text=[NSString stringWithFormat:#"%#%#",displayNameLabel.text,[my_info objectForKey:#"name"]];
[registerRequest setObject:[my_info objectForKey:#"name"] forKey:#"displayName"];
//[registerRequest setObject:[my_info objectForKey:#"email"] forKey:#"emailId"];
[registerRequest setObject:[my_info objectForKey:#"uid"] forKey:#"uid"];
[SharedPreferenceClass setFBUID:[my_info objectForKey:#"uid"]];// 30 sept
[registerRequest setObject:[my_info objectForKey:#"pic_square"] forKey:#"profilePic"];
NSString* picPath = [my_info objectForKey:#"pic_square"];
if (picPath.length>0) {
[SharedPreferenceClass setUserProfilePictureDefault:picPath];
}else{
[SharedPreferenceClass setUserProfilePictureDefault:#""];
}
//displayName.text=[my_info objectForKey:#"name"];
[self hideActivityIndicator];
}
}];
}
Thanks in advance.

Answer 1

I used this to open session when FB credentials are available in phone settings
// Initialize a session object
FBSession *session = [[FBSession alloc] init];
// Set the active session
[FBSession setActiveSession:session];
[session openWithBehavior:FBSessionLoginBehaviorWithFallbackToWebView
completionHandler:^(FBSession *session,
FBSessionState status,
NSError *error) {
// Respond to session state changes,
NSLog(#"fb open session %#",error);
[self sessionStateChanged:session state:status error:error];
}];
And once session is opened I have used following code to get FB friends data.
NSArray *permissions=[[NSArray alloc]initWithObjects:#"email,publish_actions",nil];
dispatch_async(dispatch_get_main_queue(), ^{
[FBSession openActiveSessionWithReadPermissions:permissions
allowLoginUI:YES
completionHandler:
^(FBSession *session,
FBSessionState state, NSError *error) {
NSLog(#"fb open session");
[self sessionStateChanged:session state:state error:error];
}];
});
