"If a secondary thread of an application wants to cause portions of the view to be redrawn on the main thread, it must not do so using methods like display, setNeedsDisplay:, setNeedsDisplayInRect:, or setViewsNeedDisplay:. Instead, it should send a message to the main thread or call those methods using the performSelectorOnMainThread:withObject:waitUntilDone: method instead."
I've been reading that doc. I have no idea why I didn't know this before. Probably because I've had to do very little thread programming in my career. Lucky me!
