Honestly I would recommend a thread-confinement strategy. If you have some other thread that wants to add an object to the array, it should message the thread that owns that array (I'm guessing the main thread here) and tell it to add the object. TN2109 discusses this strategy along with sample code: <http://developer.apple.com/library/ios/#technotes/tn2109/_index.html> -- David Duncan _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
