Facebook Login, got myself into a bit of a spot.
Unfortunately for the job I am doing I only have access to Snow Leopard running xcode 3.2.6 and cannot alter from that. Blast from the past I know.
To get facebook login working using FB SDK 3.0 I used:
AppDelegate.h:
#import <FacebookSDK/FacebookSDK.h>
....
@property (retain, nonatomic) FBSession *session;
AppDelegate.m:
@synthesize session = _session;
...
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
return [self.session handleOpenURL:url];
}
Then in my FBLoginViewController.m viewDidLoad:
MyAppDelegate *appDelegate;
appDelegate = [[UIApplication sharedApplication]delegate];
if (!appDelegate.session.isOpen) {
appDelegate.session = [[FBSession alloc] init];
if (appDelegate.session.state == FBSessionStateCreatedTokenLoaded) {
[appDelegate.session openWithCompletionHandler:^(FBSession *session,
FBSessionState status,
NSError *error) {
}];
}
}
Now this worked on the simulator 4.3. I think confirming I have the fb App Id set correctly in the plist, the app set up correctly etc.
However when testing on a device with IOS 6 it crashes with relevant sections of crash log saying:

What I have tried:
Now obviously with xcode 3.2.6 I cannot run via xcode and access the console for further debugging on my IOS 6 device. So I sent the project to a friend (without paid account so can't test on device) who confirmed it worked on xcode 4.5 and with simulator 6.
So if it works on the simulator 6 and 4.3 why would it not work on IOS 6 device? I am a little stumped....
After playing around (just commenting lines out etc) I think it is crashing at this line:
appdelagate.session = [[FBSession aloc] init];
But am finding it hard to be sure or have any idea why.
Would love some ideas or help, Thanks.
The only solution I could find was to upgrade to xcode 4.2 for snow leopard. I didn't realise xcode 4.2 was an option for snow leopard. However it is. The code above worked immediately with no changes in xcode 4.2.
