The only real difference between the two is the ownership semantics of the returned object. For ‘new’ it’s +1 and for ‘array’ it’s +0. However, in an ARC environment, ARC takes care of the ownership for you, so you can use them interchangeably. You might care about the difference if, say, you’re creating 10’s of thousands of arrays, because the +0 ownership may be implemented by autoreleasing the object, which adds work in draining the autorelease pool later. However, ARC can sometimes avoid even the autorelease, so worrying about this in advance is pointless. AFAICT, the main reason *not* to use ‘new’ is to avoid generating anxiety for those who come back to read the code later, and who might worry that the inconsistency means something. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
