Answer 1

add target at the time of segmentedControl creation like below

 [segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];

in that selector

-(IBAction) segmentAction:(id)sender{
    UISegmentedControl *segmentedControl = (UISegmentedControl *)sender;
        NSLog(@"Segment clicked: %d", segmentedControl.selectedSegmentIndex);
    switch (segmentedControl.selectedSegmentIndex) {
            case 0:
              self.segmentLabel.text =@"Segment 1 selected.";
              break;
            case 1:
              self.segmentLabel.text =@"Segment 2 selected.";
              break;

            default:
               break;
           }
