Question

So after a long time of debugging here is whats happening. (Using Facebooks Graph API)

When I click my post to facebook button when the facebook app is not installed, the login redirects to safari, logs on, and asks to allow permision for my app, then returns back to my app.. perfect.

If I have the official facebook app installed, the app redirects to the facebook app, and shows no dialog before returning back to my app, with an unknown error.

Basically why is the posting feature not working when authentication goes through the app and not the browser?

Any help would be greatly appreciated!

GO to Facebook.m file and comment the following lines in the – (void)authorizeWithFBAppAuth:(BOOL)tryFBAppAuth safariAuth:(BOOL)trySafariAuth method,

       - (void)authorizeWithFBAppAuth:(BOOL)tryFBAppAuth
                            safariAuth:(BOOL)trySafariAuth {
         //some line of code for initial setup

    //Comment these lines
          /*UIDevice *device = [UIDevice currentDevice];
            if ([device respondsToSelector:@selector(isMultitaskingSupported)] && [device isMultitaskingSupported]) {
                if (tryFBAppAuth) {
                    NSString *fbAppUrl = [FBRequest serializeURL:kFBAppAuthURL params:params];
                    didOpenOtherApp = [[UIApplication sharedApplication] openURL:[NSURL URLWithString:fbAppUrl]];
                }*/
   //code to open the facebook login page

}

Why you want do means,Initially it was set to open the Facebook in case of availability of credentials
