Clipping multiple paths out of UIImage

In my drawRect method I draw a UIImage, eg 

[[UIImage imageNamed:@"shape.png"] drawInRect:CGRectMake(50,50,50,50)];

I want to be able to clip multiple shapes out of the shape so the background of the view is shown. I can't seem to get the quartz clipping methods to behave as I want.

Can anyone help push me in the right direction?

Thanks!

  • I think what you are wanting is to create a mask and apply that to a UIImage. Take a look here: Rounded corners question.
