If you want to draw to a layer on a separate thread, you need to run the runloop on that thread, as Core Animation is pretty highly dependent on the run loop operating. If you call -setNeedsDisplay on a thread where you never run the runloop, then it is likely that the layer's -display method will not be called until the thread terminates, which is likely your issue. -- David Duncan Apple DTS Animation and Printing _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
