title: How would you define a simple "min" method in obj-c
body: <p>I want to define a min and max methods in a Utils class.</p>
  
  <pre><code>@interface Utils
  
  int min(int a, int b);
  int max(int a, int b);
  
  @end
  </code></pre>
  
  <p>But I don't want to have named parameters. It would be a too heavy notation. I wanted to use the C-style definition. But then <code>[Utils min(a, b)]</code> as a call doesn't work. What is my problem?</p>
  
  <p>Thanks in advance for any help</p>
