用法：

设置全局属性@property (nonatomic, strong)UISegmentedControl *control;

在viewDidLoad中设置control默认选择0：

_control.selectedSegmentIndex = 0;

具体代码：

//设置滚动scrollView

- (void)setScrollView {

self.scrollView = [[UIScrollView alloc]initWithFrame:CGRectMake(0, 64, KScreenWidth, KScreenHeight-108)];

_scrollView.delegate = self;

_scrollView.backgroundColor = [UIColor orangeColor];

_scrollView.bounces = NO;

_scrollView.contentSize = CGSizeMake(KScreenWidth*3, 0);

self.tableView1 = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, KScreenWidth, KScreenHeight-108)];

_tableView1.delegate = self;

_tableView1.dataSource = self;

[_tableView1 registerNib:[UINib nibWithNibName:@"Eight1TableViewCell" bundle:nil] forCellReuseIdentifier:@"Eight1TableViewCell"];

self.tableView2 = [[UITableView alloc]initWithFrame:CGRectMake(KScreenWidth, 0, KScreenWidth, KScreenHeight-108)];

_tableView2.delegate = self;

_tableView2.dataSource = self;

[_tableView2 registerNib:[UINib nibWithNibName:@"Eight3ViewCell" bundle:nil] forCellReuseIdentifier:@"Eight3ViewCell"];

self.tableView3 = [[UITableView alloc]initWithFrame:CGRectMake(KScreenWidth*2, 0, KScreenWidth, KScreenHeight-108)];

_tableView3.delegate = self;

_tableView3.dataSource = self;

[_tableView3 registerNib:[UINib nibWithNibName:@"Eight3ViewCell" bundle:nil] forCellReuseIdentifier:@"Eight3ViewCell"];

[self.scrollView addSubview:self.tableView1];

[self.scrollView addSubview:self.tableView2];

[self.scrollView addSubview:self.tableView3];

[self.view addSubview:self.scrollView];

}

//设置Control的位置内容UI

- (void)setSegmentView {

self.control = [[UISegmentedControl alloc]initWithItems:[NSArray arrayWithObjects:@"贡献查询",@"奖金明细",@"交易明细", nil]];

UIImage *dividerImage = [UIImage imageNamed:@"chengxian"];

UIImage *segmentSelected = [UIImage imageNamed:@"segcontrol_sel.png"];

UIImage *segmentUnSelected = [UIImage imageNamed:@"segcontrol_Unsel.png"];

[self.control setDividerImage:dividerImage forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

[self.control setBackgroundImage:segmentSelected forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];

[self.control setBackgroundImage:segmentUnSelected forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

//修改字体的默认颜色与选中颜色

NSDictionary *dic = [NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],UITextAttributeTextColor,  [UIFont boldSystemFontOfSize:12.0f],UITextAttributeFont ,[UIColor whiteColor],UITextAttributeTextColor ,nil];

NSDictionary *dics = [NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],UITextAttributeTextColor,  [UIFont boldSystemFontOfSize:12.0f],UITextAttributeFont ,[UIColor whiteColor],UITextAttributeTextColor ,nil];

[self.control setTitleTextAttributes:dic forState:UIControlStateNormal];

[self.control setTitleTextAttributes:dics forState:UIControlStateSelected];

[_control addTarget:self action:@selector(layoutManager:) forControlEvents:(UIControlEventValueChanged)];

_control.frame = CGRectMake(0, 0, 305, 35);

//    [_control setTintColor:[UIColor whiteColor]];

[self.navigationItem setTitleView:_control];

}

选中方法：

-(void)layoutManager:(UISegmentedControl *)sender { 

      switch (sender.selectedSegmentIndex){

case 0:            [_scrollView setContentOffset:CGPointZero];             

          break;      

case 1:            [_scrollView setContentOffset:CGPointMake(KScreenWidth, 0)];            break;       

case 2:            [_scrollView setContentOffset:CGPointMake(KScreenWidth*2, 0)];        default:       

    break;   

}}

滚动代理方法：

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView {    self.control.selectedSegmentIndex = _scrollView.contentOffset.x /KScreenWidth;    if (scrollView == _scrollView) {        

    if (scrollView.contentOffset.x >KScreenWidth/2 &&scrollView.contentOffset.xKScreenWidth*3 /2){

[self.scrollView setContentOffset:CGPointMake(KScreenWidth*2, 0) animated:YES];

}else {

[self.scrollView setContentOffset:CGPointZero animated:YES];

}

}

}
