2つのuisegmentedcontrolsが表示されています。1つは下部にあり、もう1つはナビゲーションバーにあります。一番下のものは正常に機能しており、ナビゲーションバーにあるものが表示されますが、タッチイベントは検出されません。下のセグメント（作業中）のコードは次のとおりです。

    footerSegment = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"1", @"2", nil]];
[footerSegment setFrame:CGRectMake(5, 6, 310, 30)];
[footerSegment setSegmentedControlStyle:UISegmentedControlStyleBar];
footerSegment.selectedSegmentIndex = 0;
//segmentFiltering.tintColor = [UIColor colorWithWhite:80.0/255.0 alpha:1.0];
[footerSegment addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
[footerSegment setTag:0];
[footerSegment setBackgroundColor:[UIColor clearColor]];
UIImage *segSelected = [[UIImage imageNamed:@"segment_sel.png"] stretchableImageWithLeftCapWidth:5.0 topCapHeight:0];
UIImage* menuRightImage = [[UIImage imageNamed:@"button.png"] stretchableImageWithLeftCapWidth:5.0 topCapHeight:0.0];
[footerSegment setBackgroundImage:menuRightImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[footerSegment setBackgroundImage:segSelected 
                            forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];

UIImage *segmentDividerImg = [[UIImage imageNamed:@"div.png"] stretchableImageWithLeftCapWidth:0 topCapHeight:0];
// Image between two unselected segments.
[footerSegment setDividerImage:segmentDividerImg forLeftSegmentState:UIControlStateNormal
                rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
// Image between segment selected on the left and unselected on the right.
[footerSegment setDividerImage:segmentDividerImg forLeftSegmentState:UIControlStateSelected
                rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
// Image between segment selected on the right and unselected on the right.
[footerSegment setDividerImage:segmentDividerImg forLeftSegmentState:UIControlStateNormal
                rightSegmentState:UIControlStateSelected barMetrics:UIBarMetricsDefault];

[footerToolBar addSubview:footerSegment];

ナビゲーションバーのコードは以下のとおりです（表示されますが機能しません）：

    headSegment = [[UISegmentedControl alloc]
               initWithItems:[NSArray arrayWithObjects:@"A", @"B", nil]];
[headSegment setFrame:CGRectMake(50, 7, 200, 29)];
[headSegment setSegmentedControlStyle:UISegmentedControlStyleBar];
headSegment.selectedSegmentIndex = 0;
[headSegment addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];

[headSegment setBackgroundColor:[UIColor clearColor]];
[headSegment setBackgroundImage:menuRightImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[headSegment setBackgroundImage:segSelected forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];

[headSegment setDividerImage:segmentDividerImg forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[headSegment setDividerImage:segmentDividerImg forLeftSegmentState:UIControlStateSelected rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[headSegment setDividerImage:segmentDividerImg forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateSelected barMetrics:UIBarMetricsDefault];
[headSegment setTag:1];
[self.navigationController.navigationBar addSubview:headSegment];

アクションのコード：

    -(void)segmentAction:(UISegmentedControl*)sender
{
    if(sender.tag == 0){
    NSLog(@"Selected index: %d", sender.selectedSegmentIndex);
    }
    else{
        if (sender.selectedSegmentIndex = 1) {
            NSLog(@"Selected HEAD index: %d", sender.selectedSegmentIndex);
        }

}

[self.navigationController.navigationBar addSubview:headSegment];

That is not how you add things to a navigation bar. You must work by way of your navigation controller's navigationItem. You can make the segmented control its titleView or you can wrap it in a bar button item and make that one of the right or left buttons.
