c# - 如何在 MainPage 中调用异步方法

Question

public partial class MainPage : ContentPage
{    
    public  MainPage()
    {
        InitializeComponent();
    }
}

我想在这里打电话:

var status = await Permissions.CheckStatusAsync<Permissions.LocationWhenInUse>();

怎么做？

Answer 1

在 OnAppearing 中调用它

public override async void OnAppearing()
{
    var status = await Permissions.CheckStatusAsync<Permissions.LocationWhenInUse>();
}
