The code below in my drawRect method draws a rectangle on my view controller. I'd like to set a corner radius to this. What am I missing?
CGRect rectangle = CGRectMake(20, 22, 280, 460);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetRGBFillColor(context, 255, 255, 255, 1.0);
CGContextSetRGBStrokeColor(context, 1.0, 0.0, 0.0, 1.0);
CGContextFillRect(context, rectangle);
