Facebook iOS SDK - Strange Effects in Writing to Status - iphone

Question

I'm updating my app to use xCode 4, iOS5 and the latest Facebook SDK. All was working fine before.
Now, two strange things are happening and despite reviewing all the code and searching the forums, I can't see why.
See update below.
Logging in for first time
When the user has just logged in, if they either share the status or cancel the attempt to do so, a script is displayed as follows:
<script type="text/javascript"> window.location.href="fbconnect:\/\/ success#_=_";
</script>
All other functionality (e..g when its not the first time) seems to work fine.
I suspect this is something to do with call backs not firing, but I've double checked all the delegate setting etc. All the facebook delegate methods are in the appDelegate and then referred to from the view controller.
Has anyone else had this issue? Any pointers would be warmly welcomed. I haven't posted any code yet as I'm not sure which bit to focus on and I've used all the standard code from the facebook developer site.
Many thanks,
Chris.
UPDATE
Thanks to #Kristofer Sommestad and #Senior for their help. I had a number of issues.
Don't Authorise Twice
The feed dialog request also requests an authorisation, so don't request them both at the same time.
Updated SDK
The SDK was updated after I found my issues - so keep checking.
What I hadn't realised was that the required code to use the SDK code had changed, specifically the code to call the feed dialog. Check out https://developers.facebook.com/docs/reference/dialogs/feed/.
What Logout Means
Logging out just logs the user out of your App, not out of facebook.

Answer 1

I also experienced the first issue, but solved it by making sure authentication wasn't triggered twice. Initially, I had done the following:
[_facebook authorize:permissions];
[_facebook dialog:#"feed" andParams:params andDelegate:self];
Not sure this is your problem, but I noticed that this messed things up as it actually triggered 2 authentication dialogs, where the second one ended up with the Javascript output you're also seeing.
For some reason I had figured that the second one wouldn't trigger a dialog if authorize already had done so....
Instead, I made sure to authorize: first, but not trigger the dialog:andParams:andDelegate until the authorization was completed with -fbDidLogin (and saving the dialog data to share as an instance variable).
Haven't seen any issues with still being able to post messages, but maybe it's related to the first issue somehow (?).
Hope this helps you out too.

Answer 2

Okay, I just did a pull from the GitHub repository, and I'm not getting this error anymore. It is, however, calling (void)dialog:(FBDialog*)dialog didFailWithError:(NSError *)error
Try updating to the latest version of the SDK and trying again.

Answer 3

This unwanted javascript-view bothers me too.
I just use the facebook feed dialog [facebook dialog: #"feed" andParams: myParameters andDelegate: ptrMyDialogDelegate];. Like shown at https://developers.facebook.com/docs/reference/dialogs/feed/. I do no other authorization anywhere else.
The Delegate is my AppModel-Class (not the AppDelegate). All methods of the FBDialogDelegate-Protocol are called correctly but after I close this annoying view.
I didn't use GIT. I downloaded the ZIP-File and copied all source files *.[h|m] from src/ directory (including src/JSON/ subdir) and the FBDialog.bundle (23 files in total) into my existing project.
Does it make any difference if I download the ZIP-File or clone the Facebook iOS SDK GIT-Repository?
To integrate the Facebook classes into my existing MyApp-project (means MyApp class tree like shown in Xcode Project Navigator) I do have to copy (e.g. drag'n drop or Xcode "Ad Files ...") the Facebook classes the same way, don't I?
