Assigning something to an instance variable doesn’t cause it to get retained unless you’re building for ARC. For manual retain-release, you have to retain it yourself or it will get released at some indeterminate time in the future. > If I call retain on it, do I have to call release on > it later? Yes (again, unless you’re using ARC). Do it in your -dealloc method. > I create another NSDate, on the stack, to hold "now" for use within that > function. Do I need to retain that too? Yes. It would be a good idea to read Apple’s Memory Management documentation before going any further, really. http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/MemoryMgmt/Articles/mmRules.html Charles _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
