iPhone SDK: How to trigger drawRect on UIView subclass after orientation change?

I am subclassing a UIView and overwrite the drawRect method. I'm noticing that the view's drawrect is only being called when the view first loads. After that it is never called again. How to I make sure it gets called after an orientation change? I've tried calling setNeedsDisplay on the view before and after the rotation and that doesn't do it.

to answer this and the other 94,000 similiar questions about view rotation/drawrect funkiness,

-(id)initWithFrame:(CGRect)frame
{
    if(self=[super initWithFrame:frame]) {
        self.autoresizesSubviews=YES;
        self.autoresizingMask=UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
    }
    return self;
}

[myView setContentMode:UIViewContentModeRedraw];

You can set this in IB as well (i.e., set mode to "redraw")

This was a bug related to something completely different. setNeedsDisplay does indeed cause drawRect to be called.
