- (bool)tableview:(uitableview *)tableview caneditrowatindexpath:(nsindexpath *)indexpath {      return yes; }

however, if have delete button revealed, , @ same time use navigation of uinavigationcontroller, i.e. when popviewcontrolleranimated:, app crashes following message:

[viewcontroller tableview:caneditrowatindexpath:]: message sent deallocated instance 0xaae64d0
