redraw using drawRect

Question

I have a subclass of UIView in which it has a drawRect in it. It basically draws a line and an image. I have drawn this in viewDidLoad, but need to change the layout when the view changes to landscape. How can I redraw this?

Answer 1

Set the view's contentMode to UIViewContentModeRedraw. The view will call [self setNeedsDisplay] whenever its bounds change. You will only have to resize the view as needed.
