C#IOS将事件处理程序设置为表行

本文关键字：设置 程序 事件处理 C#IOS | 更新日期: 2023-09-27 18:25:04

我使用的是UITableViewController。

我希望在触摸表中的特定行后重定向到另一个页面，而不是显示警报视图。

我有这个代码，但它不工作

public override void RowSelected (UITableView tableView, NSIndexPath indexPath)
{
    new UIAlertView("Row Selected", tableItems[indexPath.Row], null, "OK", null).Show();
    tableView.DeselectRow (indexPath, true); // normal iOS behaviour is to remove the blue highlight
    //call the next screen
    if(this.accountRegistration== null) {
        this.accountRegistration = new AccountRegistration();
    } 
    this.NavigationController.PushViewController(this.accountRegistration,    true); 
}

C#IOS将事件处理程序设置为表行

我正在更改我的答案，因为我没有意识到你在使用UITableViewController。

在AppDelegate.cs文件中，您需要将rootNavigationController设置为新的UINavigationController:

    [Register ("AppDelegate")]
    public partial class AppDelegate : UIApplicationDelegate
    {
        // class-level declarations
        UIWindow window;
        UINavigationController rootNavigationController;
        public override bool FinishedLaunching (UIApplication app, NSDictionary options)
        {
            this.window = new UIWindow (UIScreen.MainScreen.Bounds); 
            //---- instantiate a new navigation controller 
            this.rootNavigationController = new UINavigationController(); 
            this.rootNavigationController.PushViewController(new MyUITableViewController(), false);
            //---- set the root view controller on the window. the nav 
            // controller will handle the rest
            this.window.RootViewController = this.rootNavigationController;
            this.window.MakeKeyAndVisible (); 
            return true;
        }
        ....

从那时起，您的UITableViewController应该始终具有对此的引用。NavigationController。

此代码适用于

[注册（"AppDelegate"）]公共分部类AppDelegate:UIApplicationDelegate{//类级声明UIWindow窗口；UINavigationController根NavigationController；

    public override bool FinishedLaunching (UIApplication app, NSDictionary options)
    {
        this.window = new UIWindow (UIScreen.MainScreen.Bounds); 
        //---- instantiate a new navigation controller 
        this.rootNavigationController = new UINavigationController(); 
        this.rootNavigationController.PushViewController(new MyUITableViewController(), false);
        //---- set the root view controller on the window. the nav 
        // controller will handle the rest
        this.window.RootViewController = this.rootNavigationController;
        this.window.MakeKeyAndVisible (); 
        return true;
    }
