copied!<p>You are leaking the <code>sqlite3</code> object, because you don't call <code>sqlite3_close</code> on it when <code>sqlite3_open</code> succeeds.</p> <p>Your method is named <code>getDataToDisplayTierOne:</code>. By <a href="http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/MemoryMgmt/Articles/mmRules.html" rel="nofollow">Cocoa convention</a>, that method should return an object that the caller does <em>not</em> own. So you should be sending <code>autorelease</code> to <code>aTierOneData</code> before returning it. If you want the caller to own the returned object, you should name the method something like <code>newDataToDisplayTierOne:</code> or <code>mutableCopyDataToDisplayTierOne:</code>.</p> <p>We can't help you understand why your app crashes unless you show us the code that calls <code>getDataToDisplayTierOne:</code> and uses the returned dictionary.</p> <h3>Update</h3> <p>In <code>fetchDataForTierOne</code>, you are allocating/initing an empty <code>NSMutableDictionary</code>, storing a pointer to it in <code>myTierOneDict</code>, and then immediately leaking it by setting <code>myTierOneDict</code> to the return value of <code>getDataToDisplayTierOne:</code>. Why did you think you needed to store a pointer to an an empty dictionary in <code>myTierOneDict</code>?</p> <p>The code you posted doesn't send <code>release</code> or <code>autorelease</code> to the dictionary created in <code>getDataToDisplayTierOne:</code>, so you might be leaking that dictionary also.</p> <p>The code you posted doesn't send <code>release</code> or <code>autorelease</code> to the array that <code>myTierOneData</code> points to, so you might be leaking that also.</p>
