FaceBook Connect

@lmarcogimenez
Did you try to pass symbols such as "?" or "=" from JS to Obj-C via JSON?
If the object contains one of those two symbols, the passing fails.

Thanks,

Hey. im sorta confused as to how the Facebook Connect works.

I've got an app where I would like people to be able to login, then a pre-made message can be posted on their wall to promote the app.

If someone could point me in the right direction as to how I need to change this sample to work in that way, that would be great!

Thanks

I've got FBConnect working now, and a pretty good idea of how to get it implemented well. My only issue is that I lose the session after quitting the app, even if I select "Keep Me Logged In". Is there a way to prevent it from logging out so that my users don't have to worry about logging in each time they start the app? I know it's possible because I have apps that do it. I just can't seem to find any documentation out there on that specific item.

EDIT: I see that you're supposed to use [session resume] to resume a session. Any ideas on how to implement this?

Has anyone had any luck in figuring this out? My current issue is that I'm trying to post a story to the user's wall, but because I can't tell if they're logged in, when I call the method to post the story, it won't load if they're not logged in. Is there a way for me to tell?

I'd love to get sessions to work too.
In addition, the load friends feature does not work at all for me, no matter how much I wait.
Did Facebook change their API and broke this?

Just FYI, I have managed to get sessions to work, I'll post here the code changes so everyone can benefit.
In AppFBController.m, change the init function to the following:

Code: Select all

- (void)initSession
{
   _session = [[FBSession sessionForApplication:kApiKey secret:kApiSecret delegate:self] retain];
   NSInteger* connStatus = [_session resume];
   [self._webView performSelectorOnMainThread:@selector(stringByEvaluatingJavaScriptFromString:) withObject:[NSString stringWithFormat:@"connectionStatus('%d')", connStatus] waitUntilDone:NO];
   self._friendsList = nil;
}


then in your html code you can implement this function:

Code: Select all

var connStatus;

function connectionStatus(status)
{
  connStatus = status;
  if (connStatus == 1)
  {
    loginStatusChanged(1);
  }
 
}


Make sure you call it with the body onload property to setup the initial status display.
The variable connStatus will be 1 whenever a session is successfully resumed.

On a side note, I have worked on this using Sunny's code example, but when I import it in my code I get loads of build errors because the Facebook libraries cannot be found.
Anyone had luck with this?

"Targets->YOU_TARGET->Get Info->Build->Header Search Paths"
Make sure you have FB headers in the place, compare file structure and "Header Search Paths" in sample code and in your example
That should solve your problem

[broly]

Yup, I figured this out last night, it was missing the headers.
All now works perfectly

wondering if you got this to work or can i email you sunny? I don't need everything that FB connect offers, i just want to connect to facebook and have the user share a pre made message that they are using my app, seems to be pretty simple
