Is drawRect: called on multiple threads when using a CATiledlayer?

I know that drawLayer: and drawlayer:inContext: are called on multiple threads when using a CATiledlayer, but what about drawRect:?

Apple's PhotoScroller example code uses drawRect: to get its images from disk, and it has no special code for handling threads.

I am trying to determine whether my model for a CATiledLayer must be thread-safe.

  • Have you seen this technical Q&A from Apple?

    It doesn't answer your question directly, but it could help you decide how to implement your model.
