Except it's quite wrong from a memory management point of view. As well as the excellent advice you've already received, you really must take my advice about not just reading but KNOWING the memory management rules: http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/MemoryMgmt/MemoryMgmt.html C++, with which you're familiar, has no built-in memory management except allocation and free. You have to track those allocations yourself if you are to prevent leaks and so on. In Cocoa, this tracking is about 80% handled for you provided you follow the rules. The rules are there to ensure that the tracking works. (Or you can enable garbage collection and then the tracking is 100% handled for you). > although I have to admit I am unsure really what the "retain" will > actually do here with respect to memory. Which means you haven't read the rules, let alone committed them to heart. I urge you to do so before progressing further. --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
