ios - How to utilize a UISegmentedControl With a UITableViewController? -

i have uitableviewcontroller has 5 different sections, & each section contains individual cell. in section 1 have uisegmentedcontrolthat offers 2 options default segment 1 picked rest of sections (the other 4) correspond segment 1. however, problem having is: having ability switch uitableview has other sections & cells correspond segment 2, when of course segment 2 selected in uisegmentedcontrol

i using storyboards project.

i know question of how achieve has been asked thousand times, , know how if working regular view controllers, new working uitableviewcontroller , giving me hard time.

things have tried:

no.1: tried deleting uitableviewcontroller , replacing normal viewcontroller , sub uitableview main view. problem given error xcode because static cells require uitableviewcontroller work, (unfortunately working static cells).

no.2: have tried hide cells conditional uisegmentedcontrol display appropriate cells appropriate selection, did not work because not able add other sections & cells on top (as have done regular uiviewcontroller.

this code used try method # 2 :

- (ibaction)segmentedcontrol:(id)sender {      uisegmentedcontrol *segmentedcontrol = (uisegmentedcontrol *) sender;     nsinteger selectedsegment = segmentedcontrol.selectedsegmentindex;      if (selectedsegment == 0)     {         upick= 0;         self.lengthcell.hidden=no;         self.widthcell.hidden=no;         self.depthcell.hidden=no;         self.flowcell.hidden=yes;      }     else if (selectedsegment == 1)     {         upick =1;         self.lengthcell.hidden=yes;         self.widthcell.hidden=yes;         self.depthcell.hidden=yes;         self.flowcell.hidden=no;     }  } 

no.3: countless hours of research on net can't seem find exact results looking for, show how uiviewcontroller , steps different particular case.

i appreciate advice & overall direction take here because stuck. guys!

1. have cells need available in table view controller.

2. in table view's datasource methods (i.e. numberofsections, numberofrowsinsection, cellforrowatindexpath) can set correct numbers , data 2 states.

3. when segmented control changes, can 2 things. either reloaddata, suggested before, not animations. or use insertrowsatindexpaths:withrowanimation: , deleterowsatindexpaths:withrowanimation: animation effect.

e.g. showing sections 1-2 in case 1 , sections 3-6 in case 2 (section 0 being top section); each section has 2 rows
