To do this you are going the right way about it.

You need to create a custom view that positions these eight handles depending on the size of the view. When the view changes size you then need to reassess where those handles are so maybe have a function thats called when the view is resized and in here you change the location of each handle just by changing its x and y origin depending on the view size.
