title: Using alloc, init in ARC enabled projects
body: <p>Actually I am working on a project with <code>ARC</code> enabled. I know using <code>alloc</code> and <code>init</code> is taking <code>ownership</code> of the object. I know, If I create a string like this</p>
  
  <pre><code>NSString *myString = [[NSString alloc]initWithFormat:@"Something"];
  </code></pre>
  
  <p>then I need to <code>release</code> the <code>myString</code> on myself. <strong>What If I am using ARC enabled? I cannot release on myself. So will it create a leak? Or should I don't create object like this?</strong></p>
  
  <p>I can create a string like below code too. </p>
  
  <pre><code>NSString *myString = [NSString stringWithFormat:@"Something"];
  </code></pre>
  
  <p><strong>But which type I need to use exactly for ARC enabled project ? What will happen if I use first type?</strong></p>
