Xamarin Forms如何在Android和iOS的XAML文件中调用不同的渲染器

using Xamarin.Forms;

namespace YourApp
{
    public class CustomControl : View
    {
        // Add your custom properties and methods here
    }
}

using Xamarin.Forms;
using Xamarin.Forms.Platform.Android;

[assembly: ExportRenderer(typeof(CustomControl), typeof(CustomControlRenderer))]

namespace YourApp.Droid
{
    public class CustomControlRenderer : ViewRenderer<CustomControl, Android.Views.View>
    {
        protected override void OnElementChanged(ElementChangedEventArgs<CustomControl> e)
        {
            base.OnElementChanged(e);

            if (Control == null)
            {
                // Create and set up your Android-specific control here
            }
        }
    }
}

using Xamarin.Forms;
using Xamarin.Forms.Platform.iOS;

[assembly: ExportRenderer(typeof(CustomControl), typeof(CustomControlRenderer))]

namespace YourApp.iOS
{
    public class CustomControlRenderer : ViewRenderer<CustomControl, UIKit.UIView>
    {
        protected override void OnElementChanged(ElementChangedEventArgs<CustomControl> e)
        {
            base.OnElementChanged(e);

            if (Control == null)
            {
                // Create and set up your iOS-specific control here
            }
        }
    }
}
