you need have nsmutablearray selected indexpaths. didselectrowatindexpath: then.

-(void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath *)indexpath{     if([self.selectedindexarray containsobject:indexpath]){         [self.selectedindexarray removeobject:indexpath];     }     else{         [self.selectedindexarray addobject:indexpath];     }     [tableview reloaddata]; } 

and cellforrowatindexpath: change selection this:

if([self.selectedindexarray containsobject:indexpath]){     newradiobutton.selected = yes; } else{     newradiobutton.selected = no; }
