ios - Switch doesn't work in SMSegmentViev -

i use frames smsegmentview, can not implement switch in numberofrowsinsection , cellforrowatindexpath ... when start in simulator pressing segment table not changed pressing index segment. can not understand error

we must add didselectsegmentatindex "standingtableview.reloaddata ()"
