If you could change it to mutable, other code that had a reference to that object could find its data changing out from underneath it, causing trouble. If you’re the one creating the NSData object in the first place, can you create it as an NSMutableData? Then you won’t have to make any copies. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
