DisplayAlert不在Xamarin上显示仅表示ios

Question

出于某种原因，当我仅在ios上从一个页面导航到另一个页面时，不显示displayalert。它适用于Android。这是简单的代码

//Navigating to other page
Navigation.PushAsync(new page1());

//Page1 Code

public page1()
{
   InitializeComponent();
   DisplayAlert("Test", "Test Successful", "Ok");

}

Answer 1

尝试下面它会适合你

Device.BeginInvokeOnMainThread (() => 
 {

  DisplayAlert("Test", "Test Successful", "Ok");

 });

Answer 2

另一种变体 - 从当前MainPage调用DisplayAlert。

await Application.Current.MainPage.DisplayAlert("Test", "Test Successful", "Ок");
