Showing the Delete button in UITableView

开发者_C百科I have a UITableView.

When I move my mouse from right to left on cell it is not displaying the delete button.

Please tell me how to do this?

tableView:commitEditingStyle:forRowAtIndexPath:
tableView:canEditRowAtIndexPath:
tableView:editingStyleForRowAtIndexPath: 

I've found a topic of somebody that had the same problem as you.. See this thread
