Change the button titles on SLComposeServiceViewController?

Question

Is there a way to change the button titles on the SLComposeServiceViewController? I tried to change the bar button items on the navigation item, but those aren\'t the right

Answer 1

I just found a way to do it:

class CustomServiceViewController: SLComposeServiceViewController {
    override func viewDidLoad() {
        let navigationBar = view.subviews.first?.subviews?.last? as? UINavigationBar
        let postButton = navigationBar?.subviews.last? as? UIButton
        let cancelButton = navigationBar?.subviews.last? as? UIButton
        postButton?.setTitle("Done", forState: .Normal)
    }
}

Be warned - it's a fragile solution, based on undocumented internals of SLComposeServiceViewController
