__weak pointer collection firing prematurely???

I am looking at something very strange. I have a document object, that has an object that it owns; which has a __weak pointer back to the document object. Another object also has an indirect pointer to the document object. So, something like this: @interface MyDoc : NSDocument { MySubOb

Core Graphics optimisation

Hi everyone, on iOS, I was using the following "immediate CG code" to display hundreds procedural sprites : CGContextSetShadow(Ctx, CGSizeMake(3, 4), 3.0f); CGMutablePathRefShapePath = CGPathCreateMutable(); CGPathAddArc(ShapePath, &CGAffineTransformIdentity, radius+3, radius+3, radius,

Re: Core Graphics optimisation

You have no time to watch WWDC 2012 presentations and like to avoid OpenGL ES as an alternative, how on earth are you going to write a fast app with thousands of drawings on a device with (in worst case) 256 MB of internal memory? I am not sure OpenGL ES will help, and one session from WWDC will
