Answer 1

A first simple approach would be to use UIBezierPath to draw a line in drawRect: of your view. You would have to convert the values you receive into the coordinate system of your view and then create an instance of UIBezierPath where you add all relevant point with addLineToPoint:. In the end you call [bezierPath stroke] to actually draw the line. You could create a Datasource-Protocol for your ViewController and a reload method on your view which triggers the views to redraw whenever new data is received.
