Not knowing what properties objects have is no excuse, because all you have to do is open the header files and scroll to where the properties are declared and see what you can change, most property names are very self-explanatory, and the ones that aren’t enough, usually have comments saying what they do.

So please, devs out there, don’t leave the default values of your objects (unless, of course, that’s the value you need), setting them up properly it really easy to do, and it makes your app stand out.
