我是iOS开发的新手。我现在正在学习斯威夫特。我目前有一个问题,我添加导航视图控制器后,我的tableView不再显示任何内容。我不明白为什么。请帮帮我专家!!
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
let mainVC = ViewController()
let navigationVC = UINavigationController(rootViewController: mainVC)
window?.rootViewController = navigationVC;
window?.makeKeyAndVisible()
return true
}
ViewController中的代码:
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet var myTable: UITableView!
var items: [String] = ["Date Picker","List of Data","Slider","Show Image", "Web Display"];
override func viewDidLoad() {
super.viewDidLoad()
NSLog("Hello World at console");
var nib = UINib(nibName: "ListCell", bundle: nil)
myTable?.registerNib(nib, forCellReuseIdentifier: "ListCell")
// Do any additional setup after loading the view, typically from a nib.
}

如果您正在使用storyboard,请使用其实例化方法,并在storyboard中设置控制器的storyboardID
YourController *vc = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"ControllerStoryboardId"];
如果是xib文件
YourController *vc = [[YourController alloc] initWithNibName:@"YourController" bundle:[NSBundle mainBundle]];
