title: Sending a Selector to another Class. And Creating an Instance of A Class
body: <p>How would I send a Selector to another class?
  I know to send it to a selector in the same file you do </p>
  
  <pre><code>[self performSelector:@selector(doSomething)];
  </code></pre>
  
  <p>and for sending it to another class I've tried </p>
  
  <pre><code>[otherClass performSelector:@selector(doSomethingElse)];
  </code></pre>
  
  <p>But I just get an error in the Debugger saying</p>
  
  <pre><code>+[otherClass doSomethingElse]: unrecognized selector sent to class 0xe5c4
  </code></pre>
  
  <p>Why is this??</p>

  <p><em>' Chances are it's not a class method but rather an instance method … '</em></p>
  
  <p>How do I create an Instance of My Class then?</p>
