title: Remove Next / Previous buttons (inputAccessoryView) for Custom Keyboard in iOS8 WebView
body: <p>Please bear with me, I searched a lot over the internet and I couldn't find a solution since it's a new API.</p>
  
  <p>I am trying to create a custom keyboard for iOS 8. It works perfectly fine except in WebView!
  It has previous-next button, which are in <code>inputAccessoryView</code>. I know it's read-only property for webview but since iOS 8 allows the users to have custom keyboard I assume this view should be editable somewhere. Has anybody run into the same issue? Any help would be appreciated.</p>
