title: what is the equivalent of object in C# for objective C?
body: <p>In c# I can declare <code>object o;</code> then I can assign <code>o=(float)5.0;</code> or <code>o="a string."</code> Is there an equivalent for Objective-C? I tried to use <code>id</code> but it does not take primitive type like float or integer. Thanks for helping.  </p>
