這里我們引入了一個名為SCNavTabBar的第三方

接下來就十分的簡單了

//頭文件

#import "SCNavTabBarController.h"

下面就是viewdidload的實現代碼

UIViewController *oneViewController = [[UIViewController alloc] init];

oneViewController.title = @"新聞";

//? ? UIView *v = [[UIView alloc]initWithFrame:CGRectMake(10, 10, 100, 100)];

//

//

//? ? [oneViewController.view addSubview:v];

oneViewController.view.backgroundColor = [UIColor brownColor];

UIViewController *twoViewController = [[UIViewController alloc] init];

twoViewController.title = @"體育";

twoViewController.view.backgroundColor = [UIColor purpleColor];

UIViewController *threeViewController = [[UIViewController alloc] init];

threeViewController.title = @"娛樂八卦";

threeViewController.view.backgroundColor = [UIColor orangeColor];

UIViewController *fourViewController = [[UIViewController alloc] init];

fourViewController.title = @"天府之國";

fourViewController.view.backgroundColor = [UIColor magentaColor];

UIViewController *fiveViewController = [[UIViewController alloc] init];

fiveViewController.title = @"四川省";

fiveViewController.view.backgroundColor = [UIColor yellowColor];

UIViewController *sixViewController = [[UIViewController alloc] init];

sixViewController.title = @"政治";

sixViewController.view.backgroundColor = [UIColor cyanColor];

UIViewController *sevenViewController = [[UIViewController alloc] init];

sevenViewController.title = @"國際新聞";

sevenViewController.view.backgroundColor = [UIColor blueColor];

UIViewController *eightViewController = [[UIViewController alloc] init];

eightViewController.title = @"自媒體";

eightViewController.view.backgroundColor = [UIColor greenColor];

UIViewController *ninghtViewController = [[UIViewController alloc] init];

ninghtViewController.title = @"科技";

ninghtViewController.view.backgroundColor = [UIColor redColor];

SCNavTabBarController *navTabBarController = [[SCNavTabBarController alloc] init];

navTabBarController.subViewControllers = @[oneViewController, twoViewController, threeViewController, fourViewController, fiveViewController, sixViewController, sevenViewController, eightViewController, ninghtViewController];

navTabBarController.showArrowButton = YES;

[navTabBarController addParentController:self];

[self.navigationController setNavigationBarHidden:NO animated:YES];

這樣就完成了
