Issue about cocoa Multi-document template

Hi everyone.
I want to start an application with the cocoa multi-document template. 
The default behavior of the application is when you launch it, a blank 
window is automatically open.

This behavior is not that I want. I thought the application should not 
open any window until users explicit open file command arrived.

So, is there any way to disable the application to open the window 
when launched? Thank you for any help.
