body: <p>How to call a function in Objective C? For example:</p>
  
  <p>I define the function in header (.h file):</p>
  
  <pre><code>-(void)abc
  </code></pre>
  
  <p>and implement this function in implementation file (.m file):</p>
  
  <pre><code>-(void)abc
  {
  //.....
  ///....
  }
  </code></pre>
  
  <p>Now how would I call this function from where I need it?</p>
