Receive error when trying to post on Twitter using ShareKit

I'm trying to use sharekit to post on Twitter and Facebook.

I have two buttons which call the following two methods:

- (IBAction) shareOnFacebook:(id)sender
{
    // Create the item to share 
    NSString *someText = @"Share on Facebook.";
    SHKItem *item = [SHKItem text:someText];

    // Share the item
    [[SHK currentHelper] setRootViewController:self.navigationController];
    [SHKFacebook shareItem:item];
}

- (IBAction) shareOnTwitter:(id)sender
{
    // Create the item to share 
    NSString *someText = @"Share on Twitter.";
    SHKItem *item = [SHKItem text:someText];

    //tried both methods to set navigationcontroller!
    [[SHK currentHelper] setRootViewController:self.navigationController];
    [SHK setRootViewController:self.navigationController];  

    [SHKTwitter shareItem:item];
}

Facebook is working only, when I try to use Twitter I get the following error:

2011-05-31 10:20:25.928 App[870:707] *** Assertion failure in -[SHK showViewController:], /Users/blaat/Dropbox/App/Classes/ShareKit/Core/SHK.m:112
2011-05-31 10:20:25.975 App[870:707] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'ShareKit: Could not find a root view controller.  You can assign one manually by calling [[SHK currentHelper] setRootViewController:YOURROOTVIEWCONTROLLER].'

Which is strange because I use the same method for Facebook to set the NavigationViewController where everything is working... I checked all the variables over and over again in the SHKConfig.h

  • Authentication OAuth
  • Application Type "Browser"
  • Callback url filled in the same in config and in dev.twitter.com
  • Consumerkey OK
  • Consumersecret OK

Anyone an idea?

Edit. I enabled debugging for Sharekit and this was the result. I still don't see where the problem is.

Edit: I got the answer

[SHK setRootViewController:self.navigationController];

needs to be:

[SHK setRootViewController:self];

Problem was that it needed a UIViewController, while I was passing a UINavigationViewController.

We use ShareKit as well. We haven't run across this one yet, but according to the docs online, ShareKit will try to use the navigation controller stack to find your root view controller, then pop a modal view controller from there. It throws this error when it can't find one.

You can correct it by manually setting the root view controller by using the following call:

[SHK setRootViewController:myViewController];
