title: How to store second (time) as a constant on ios?
body: <p>Is this the bad way to store a second value on header file?</p>
  
  <pre><code>static const int waitForDurationToRemove = 2.9;
  </code></pre>
  
  <p>I use this value on another class.</p>
  
  <pre><code>    SKAction *wait = [SKAction waitForDuration: waitForDurationToRemove];
  </code></pre>
  
  <p>This is not working properly. Is this problem with int?Thank you.</p>
