The docs at: http://developer.apple.com/documentation/Cocoa/Conceptual/Multithreading/Thr eadSafetySummary/ThreadSafetySummary.html
State: The NSView class is generally thread-safe, with a few exceptions. You should create, destroy, resize, move, and perform other operations on NSView objects only from the main thread of an application. Drawing from secondary threads is thread-safe as long as you bracket drawing calls with calls to lockFocusIfCanDraw and unlockFocus. 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: method instead. So is this legal in a secondary thread? NSImage* theImage = [[NSImage alloc] initWithContentsOfFile:someImagePath]; [imageView setImage:theImage]; [theImage release]; Note that imageView in an NSImageView in a window and both the window and the NSImageView were created on the main thread. The secondary thread is only creating an NSImage and attaching it to the NSImageView. Safe?
