我是SWIFT编程的新手(多3天)。
我迅速创建了一个示例tableview单元演示。
我在xib中使用了“Testviewcontroller”。
代码是
import UIKit
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
@IBOutlet weak var myTableview:UITableView!
let fruits = ["Apple","Banana","Grapes","Chiku","Watermalon","Bear"]
let blogSegueIdentifier = "TestViewController"
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
public func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return self.fruits.count
}
public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.subtitle, reuseIdentifier: "MyTestCell")
cell.textLabel?.text = self.fruits[indexPath.row]
return cell
}
public func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
{
let testVC = TestViewController(nibName : "TestViewController" , bundle:nil)
navigationController?.pushViewController(testVC, animated: true)
print("You have selected \(indexPath.row) row")
}
}
代理
import UIKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
return true
}
func applicationWillResignActive(_ application: UIApplication) {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
}
func applicationDidEnterBackground(_ application: UIApplication) {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
func applicationWillEnterForeground(_ application: UIApplication) {
// Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}
func applicationDidBecomeActive(_ application: UIApplication) {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
func applicationWillTerminate(_ application: UIApplication) {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
}
我的问题是
我已经使用了“didSelectRowAt indexPath”委托方法。
我无法推送新的视图控制器
请帮助我,我无法解决这个问题。
最佳答案
在对每个UIViewController
使用XIB时,需要在AppDelegate.swift
文件中添加以下代码,然后才能在navigationController
中访问ViewController.swift
。
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
let viewController = ViewController(nibName:"ViewController", bundle:nil)
let navController = UINavigationController(rootViewController: viewController)
self.window!.rootViewController = navController
self.window!.makeKeyAndVisible()
return true
}
