为Xamarin重定向UIViewController

本文关键字：UIViewController 重定向 Xamarin | 更新日期: 2023-09-27 18:14:15

我正在创建一个方法来显示一个对话框，这是我目前所做的:

public void ShowDialog(String title = "",String msg = "")
{
    this.alert.Title = title;
    this.alert.AddButton("Ok");
    this.alert.Message = msg;
    this.alert.Show();
}

这个位于一个公共类，所以它可以与其他类一起使用，

我想添加一个参数，以便在按下"确定"按钮后，它将重定向到某个UIViewController，我尝试这样做:

public void ShowDialog(String title = "",String msg = "", UIViewController view = null)
{
    this.alert.Title = title;
    this.alert.AddButton("Ok");
    this.alert.Message = msg;
    this.alert.Clicked += (object sender1, UIButtonEventArgs e) => {
                            if(e.ButtonIndex.ToString () == "0" && view != null){
                                NavigationController.PushViewController(view, true);
                            }
                        };
    this.alert.Show();
}

但显然这是不工作，我错过了什么?或者这是可能的吗?

Thanks in advance.

如何命名

Common common = new Common();
common.ShowDialog("Error","Invalid Process!!", new HomeScreen());

为Xamarin重定向UIViewController

最后我这样做了:

public void ShowDialog(String title = "",String msg = "", UIViewController instance = null, UIViewController redirectTo = null)
{
    this.alert.Title = title;
    this.alert.AddButton("Ok");
    this.alert.Message = msg;
    this.alert.Clicked += (object sender1, UIButtonEventArgs e) => {
        if(e.ButtonIndex.ToString () == "0" && instance != null && redirectTo != null){
            instance.NavigationController.PushViewController(redirectTo, true);
        }
    };
    this.alert.Show();
}

然后这样调用:

Common common = new Common();
common.ShowDialog("Error","Invalid Process!", this, new HomeScreen());
