well [ aThing release ] won’t work in ARC, I assume you really mean aThing = nil, or just letting aThing fall out of the bottom of the local scope either mark [ Thing data ] with NS_RETURNS_INNER_POINTER which is equivalent to __attribute__((objc_returns_inner_pointer)) or mark aThing with __attribute__((objc_precise_lifetime)) _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
