title: How do I create a BOOL instance variable in objective c?
body: <p>I need to create an instance variable of type <code>BOOL</code> with a default value of <code>False</code> in one of my Objective-C classes.  How do I do this? I've seen people define it in their .h file but I don't really need this variable to be public.  Thus shouldn't I put it in my .m file?  Additionally, should I make it a property? Or should I ever not make something a property?  Thanks.</p>
