Hi, I've been trying to figure out how to draw a shadow for an UIView that was added inside a UIView with addSubview.

I searched online and read the docs, but the Apple docs simply draw new shapes as shown below. I want to use the Core Graphics to add a shadow to the UIView, but am unsure how to do this to a UIView directly.

CGContextRef myContext = UIGraphicsGetCurrentContext();

//CGContextRef myContext = myCGREF;

CGSize          myShadowOffset = CGSizeMake (10, 10);// 2

CGContextSetShadow (myContext, myShadowOffset, 0);   // 3

CGContextBeginTransparencyLayer (myContext, NULL);// 4

// Your drawing code here// 5

CGContextSetRGBFillColor (myContext, 0, 1, 0, 1);

CGContextFillRect (myContext, CGRectMake (a_view.frame.origin.x, a_view.frame.origin.y , wd, ht));

CGContextEndTransparencyLayer (myContext);// 6

I know I should put this in the SuperView drawRect method, but I don't know how to make it so it adds a shadow to the views I add in addSubView.

Thanks!
