title: How do I disable a UISwitch?
body: <p>Is this possible to disable a UISwitch?  I do not mean putting it in an OFF state, I mean disabling user interaction, and having it appear gray.</p>
  
  <p>In my app I have two conditions  </p>
  
  <pre><code>if (condition == true) {  
    // UISwitch should be enabled  
  } else {  
    // UISwitch should be visible, but disabled  
    // e.g uiswitch.enable=NO;  
  } 
  </code></pre>
  
  <p>Any suggestions?</p>
