title: How to increment a variable and overwrite the old one?
body: <p>I'm new to Objective C, and I'm quite confused that the method:</p>
  
  <pre><code>-(void)increment 
  {
    count = count+1;
  }
  </code></pre>
  
  <p>doesn't increment the variable count on any method call, but just sets the variable on "1", no matter how often i call the method. This is different in Objective-C isnt it? In other languages it´s pretty basic.</p>
  
  <p>Help would be great, thanks anyway guys.</p>
