Question

I have fbconnection in my application it works fine but when i logout and re login; this is the place that the app crashes. This is the FBSession.m file. I need help with these i google it search but can’t find anything usefull. Anybody understand or know the solution?Thanks for helping.

- (BOOL)resume {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
FBUID uid = [[defaults objectForKey:@"FBUserId"] longLongValue];
if (uid) {
    NSDate* expirationDate = [defaults objectForKey:@"FBSessionExpires"];
    if (!expirationDate || [expirationDate timeIntervalSinceNow] > 0) {
        _uid = uid;
        _sessionKey = [[defaults stringForKey:@"FBSessionKey"] copy];
        _sessionSecret = [[defaults stringForKey:@"FBSessionSecret"] copy];
        _expirationDate = [expirationDate retain];

        for (id<FBSessionDelegate> delegate in _delegates) {
            [delegate session:self didLogin:_uid];// This is the place that gives EXC_BAD_ACCESS
        }
        return YES;
    }
}
return NO;
}

Edit:

- (void) viewDidLoad {
[super viewDidLoad];

static NSString* kApiKey = @"605a4eee24bc4018210207cd152aaf0e";
static NSString* kApiSecret = @"4057291afc9430895461774a43881751";
_session = [[FBSession sessionForApplication:kApiKey secret:kApiSecret delegate:self] retain];

// Load a previous session from disk if available.  Note this will call session:didLogin if a valid session exists.
[_session resume];
NSLog(@"resume");
}

this is the place i set delegate

Search your project and find all files that your are putting into the delegates. From all these file’s dealloc methods, remove them from the _delegates.

Most likely it’s crashing because your delegate object (which could be a viewController that was popped earlier) is released and the _delegates array contains a hanging pointer to it.
