title: Memory leak in NSString stringWithUTF8String
body: <p>I am making a call to a database. After my call, I've found leaks in NSString. Anybody have a solution to remove it?</p>
  
  <pre><code> NSString *pic = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectStatement, 5)];
  </code></pre>
  
  <p>In above code, I found 90% leaks. I just read data from database.</p>
