title: UITableView edit mode not working
body: <p>I'm trying to activate the edit mode for a UITableView. When I click the "Edit" button, it changes to "Done" but the round red minus signs dont show up in the table. I'm posting below some of the methods of the class. The app delegate created a Tab Bar and the views inside the tabs have navigation controllers. all is done in code, little is done with nib files. What's wrong?</p>
