title: Declare static member variables like Java's in Objective-C
body: <p>How can I make an Objective-C class with class-level variables like this Java class?</p>
  
  <pre><code>public class test
  {
  
      public static final String tableName = "asdfas";    
      public static final String id_Column = "_id";
      public static final String Z_ENT_Column = "Z_ENT";
  
  }
  </code></pre>
  
  <p>I want to access them without making an instance, like: </p>
  
  <pre><code>String abc = test.tableName;
  </code></pre>
