问题
I made this cool pie chart and now I'd like to drop a shadow under it. Is there anyway I can do it with DrawRect ?
I'd like to do it right under the pie chart (drawn using DrawRect). Suggestions are welcome

Have a look at BNPiechart here - http://bynomial.com/blog/?p=104 . The code is open source.You can use it directly.If you do not want to use the library, you can refer the code for creating the shadow.
