Summary:

Q&A1637 states:

"Important: Beginning with iOS 4.0, drawing to a graphics context in UIKit is thread-safe. This includes accessing and manipulating the current graphics stack, drawing images and strings, and usage of color and font objects from secondary threads."

But this is out of date as o f iOS 6.

Notes:

The iOS 6 SDK documentation for UIStringDrawing had this line added from the iOS 5 docs:

"The methods described in this class extension must be used from your app’s main thread."

After hard-learned experience, I've found this to be true. The Q&A really needs to be updated to reflect the current reality.
