title: "getter" keyword in @property declaration in Objective-C?
body: <p>I noticed some code example in Apple's documentation shows the following style when declaring the property:</p>
  
  <pre><code>@property (nonatomic, getter=isActivated) BOOL activated;
  </code></pre>
  
  <p>I understand it allows you to specify a certain name for your getter method. I'd like to know what is the reason and advantage to use this style. </p>
  
  <p>Will I be able to use the dot notation to get the value (e.g. BOOL aBool = someObject.isActivated)? Or should I use<br>
  <code>[someObject            isActivated];</code> 
  to access the property? Thanks!</p>
