• (void)setupViewControllers {

UIViewController *firstViewController = [[SupermarketViewController alloc] init];

UIViewController *firstNavigationController = [[UINavigationController alloc]

initWithRootViewController:firstViewController];

//实例化三个ViewController

OrderViewController *firstVC = [[OrderViewController alloc] init];

//显示三个按钮

[vc setTitles:@[@"全部", @"待收货", @"待评价"]];

//设置segmentBg的颜色

vc.segmentBgColor = [UIColor orangeColor];

vc.indicatorViewColor = [UIColor whiteColor];

[vc setViewControllers:@[firstVC, secondVC, thirdVC]];

UIViewController *secondViewController = vc;

UIViewController *secondNavigationController = [[UINavigationController alloc]

initWithRootViewController:secondViewController];

}

之后引入一个第三方JRSegmentViewController
