Question

Xamarin.iOS. Appodeal. Foundation.MonoTouchException: Objective-C exception thrown. Name: NSInvalidArgumentException Reason: -[APDImage imageUrl]: unrecognized selector sent to instance 0x280002420

class NativeAdDelegate : APDNativeAdLoaderDelegate
{
    NativeAdView _nativeAdView;

    public NativeAdDelegate(NativeAdView nativeAdView) =>
        _nativeAdView = nativeAdView;

    public override void NativeAdLoader(APDNativeAdLoader loader, NSError error) =>
        Console.WriteLine("APDNativeAd DidFailToLoadWithError");

    public override void NativeAdLoader(APDNativeAdLoader loader, NSArray nativeAds) =>
        _nativeAdView.DidLoad(nativeAds.GetItem<APDNativeAd>(0));
}

In

nativeAds.GetItem(0)

I have title and descriptionText, but I haven't images. I get exception in nativeAds.GetItem(0).IconImage.ImageUrl.

The images is required.Otherwise the property ImageUrl will return a null value ,which will cause the issue.

public override void DidLoadNativeAds(APDNativeAdLoader loader, APDNativeAd[] nativeAds)
  {
      _nativeAdView.DidLoad(nativeAds[0]);
  }

I get information [here](https://www.appodeal.com/sdk/documentation?framework=22&full=1&platform=4) . `public override void NativeAdLoader(APDNativeAdLoader loader, APDNativeAd nativeAd) { _controller.MyDelegateServiceDidLoad(nativeAd); }` – Viktor Bylbas Dec 10 '18 at 10:10

APDImage * mainImage - Bitmap of an image. An ad object contains both icon and image. It’s mandatory to use at least one of these elements.

Deprecated method.

For more details you can refer here.

public override void NativeAdLoader(APDNativeAdLoader loader, NSArray nativeAds)
{
    _nativeAdView.DidLoad(nativeAds.GetItem<APDNativeAd>(0));
}

public void DidLoad(APDNativeAd nativeAd)
{
     this.nativeAd = nativeAd;
     UIView view = new UIView();
     view.Frame = new System.Drawing.Rectangle(10, 30, 200, 200);
     view.BackgroundColor = UIColor.FromRGB(96, 36, 36);
     View.AddSubview(view);
     this.nativeAd.AttachToView(view, UIApplication.SharedApplication.Windows[0].RootViewController);
     this.myMediaView.SetNativeAd(this.nativeAd, this);
     View.AddSubview(this.myMediaView); 
}
