This is a followup to a previous post, in which I got a hint of an answer, but not the whole answer.
I created a subview in my main view, drew some circles in it, using the add the CGPathAddArc() function, which I assume creates a vector graphic result.
But when I animated the subview with CGAffineTransformMakeScale(10, 10), my circles became rather badly pixelated.
In a response to my previous thread, someone stated the the transforms operate on a cached bitmap of my subview, but that there was a means of forcing a redraw of the view with each frame. I have looked around for what that secret handshake is, but I haven't found it.
If you know how to accomplish the frame-by-frame redraw, please let me know.
Thanks in advance for any help with this.
