what is best approach of accessing data around all classes and handling it in iphone programming?
<p>I developed an application for iphone, and made all my setters and getter, and handled sqlite3 database (select, insert, delete, update) in AppDelegate.m</p>

<p>I made AppDelegate Object and used all around my application, I felt that my application started to give strange errors, and heaviness, crash.</p>

<p>then I made another class as DataManagement, then I used it and rotate objects, now there is no error, nothing like crash,,,,</p>

<p>I want to know from you seniours that what is best way to handle getters and setters and database in iphone programming?</p>

<p>any other good way, so that application became now too much heavy at all,,,,</p>
