如何从“More”选项卡项的编辑中检测选项卡项的更改?

I have 6 tab bar items, 4 titles shown directly and other 2 are in 'More'. I have added 'cell background image' on More tableview. Now the problem is, When i click "Edit" button in More tabbar item and change the tab bar items the tableview 'background image' not displaying after the changes. How can i detect the edit button pressed and the tabbar item changes? Please help me to find the solution. Thanks in advance.I have 6 tab bar items, 4 titles shown directly
