If you are going to assign another value to 'theString' before you use it, then doing this is pointless. > NSString *theString = nil; > NSString *theString; > > I thought lines 2 and 3 were the same thing. I was wrong. What is the > difference and when do you use the style shown in line 3? In C unless you explicitly initialize a local variable its value is undefined, and Objective-C inherits this behavior. I believe however that under ARC these lines are equivalent (at least thats my reading of section 4.2 on initialization at <http://clang.llvm.org/docs/AutomaticReferenceCounting.html>) but given your comments I suspect you are not using ARC. -- David Duncan _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
