如何使用MVVM将XAML标签与TapGestureRecognizer绑定？

<Label Text="点击我" >
    <Label.GestureRecognizers>
        <TapGestureRecognizer Command="{Binding TapCommand}" />
    </Label.GestureRecognizers>
</Label>

public class MyViewModel : INotifyPropertyChanged
{
    public ICommand TapCommand { get; private set; }

    public MyViewModel()
    {
        TapCommand = new Command(OnTap);
    }

    private void OnTap()
    {
        // 处理点击事件的逻辑
    }

    // 其他属性和方法...
}

public partial class MyPage : ContentPage
{
    public MyPage()
    {
        InitializeComponent();
        BindingContext = new MyViewModel();
    }
}
