I am new to iPhone development.
My app is working fine but after using it for some time and performing all the functionality sometimes a view does not open. The view contains the custom cell which contain a UIImageView and UILabel and UIImageView After using the app for long time the cell only shows the UILabel and click on cell it shows "Debugger Error Contain some invalid hexadecimal". When clicking on cell the next which is suppose to open it shows an exception
'NSInvalidArgumentException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] was unable to load a nib named "FriendShoppingListViewController"'
