title: What's the convention on placing curly braces in Objective-C?
body: <p>I have seen different conventions for Objective-C (<a href="http://en.wikipedia.org/wiki/Cocoa_%28API%29">Cocoa</a>/<a href="http://en.wikipedia.org/wiki/Cocoa_Touch">Cocoa Touch</a>) of placing the curly braces.</p>
  
  <p>The two that I have seen are:</p>
  
  <pre><code>- (void)dealloc {
      [super dealloc];
  }
  </code></pre>
  
  <p>vs.</p>
  
  <pre><code>- (void) dealloc
  {
      [super dealloc];
  }
  </code></pre>
  
  <p>This confuses me because I would expect that for such a rather small community there should be only one convention.</p>
  
  <p>Which one of the two is more common?</p>
