Instance Method Details

#dismiss(opts) ⇒ Object

remove the controller from the display heirarchy, taking into account how it is currently presented. avoid nesting animations and corrupting the UI by using whenOrIfViewState and executing on the main thread async to ensure it is not yanked out of the UI during existing animations

#present(opts) ⇒ Object

presentViewController should always be called on the next runloop to avoid quirks. this just wraps that behavior
