如果你使用storyboard作为视图控制器，那么你必须在你的tabbarcontroller类中这样写。
class CustomTabbarController : UITabBarController {
override func viewDidLoad() {
super.viewDidLoad()
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let firstViewController = FirstViewController()
let navigationController = UINavigationController(rootViewController: firstViewController)
navigationController.title = "First"
navigationController.tabBarItem.image = UIImage.init(named: "map-icon-1")
viewControllers = [navigationController]
if let secondViewController = storyboard.instantiateViewController(withIdentifier: "SecondViewController") as? SecondViewController {
let navgitaionController1 = UINavigationController(rootViewController: secondViewController)
navgitaionController1.title = "Second"
navgitaionController1.tabBarItem.image = UIImage.init(named: "second-icon-1")
var array = self.viewControllers
array?.append(navgitaionController1)
self.viewControllers = array
}
}

private lazy var tabbarViewController: UITabBarController = {
let tabbarViewController = UITabBarController()
tabbarViewController.setViewControllers([startVC,
offerVC,
benefitsVC,
shopVC,
recipesVC], animated: true)
return tabbarViewController
}()
window?.rootViewController = tabbarViewController页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
