air 26 StageWebView IOS 7 black screen

Question

Application crashes when using StageWebView on IOS 7 or lower.

I use this code:

if (StageWebView.isSupported)

{

var webView:StageWebView = new StageWebView(/* true of false does not matter in this case*/);

webView.stage = getStage();

webView.viewPort = getViewPort();

webView.loadUrl(url);

}

As a result I see black screen.

In debug mode I see exception on the line right after web view's initialization:

[Fault] exception, information=ArgumentError: Error #2004: One of the parameters is invalid.

IOS 7 does not support WKWebKit, so isn't it better to switch to UIWebKit in runtime for old versions?

Like suggests natively:

As a temporarily workaround, I wrap this code in try/catch to detect if it's truly supported:

if (StageWebView.isSupported)

{

var result:Boolean;

try

{

var webView:StageWebView = new StageWebView();

webView.stage = getStage(); // ios7 throws Exception

result = true;

}

catch(e:Error)

{

result = false;

}

finally

{

webView.dispose();

webView = null;

return result;

}

else

{

return false;

}

But I really hope that stage web view will work using both WK or UI kits
