drawrect to fit uiview no matter the size

I have a uiview class that calls a custom drawing class method with a drawrect in it. The drawrect drawing coordinates are drawn for a 433x439 uiview. When this app opens on an iPad Pro autolayout changes the size of the uiview (correctly). But the drawrect still draws to the old 'size'(433x439) and does not scale to fill the new uiview bounds.

Any idea how I can get this to work? I do not want to draw it again to the new coordinates. Seems like content mode or something should redraw? Note: I tap on these shapes to do something else. The scaling(?) that someone hopefully helps me with should not affect that, correct?

You are hardcoding your points. Of course it is going to draw in the same place and same size.

Instead, define your points as proportions of the entire view, and calculate the exact x and y values based on the rect that is passed into drawRect.

Now all you have to do is superimpose your view in the correct spot and size and the drawing should scale automatically. You can even have the user zoom and the area should just redraw itself correctly.
