Hi,
It looks like VSSpeechSynthesizer doesn't have a getter method for the
delegate, only a setter.
Try the following:
class MyDelegate : VSSpeechSynthesizerDelegate
{
override void DidFinishSpeaking(NSObject synth, bool success, IntPtr
error)
{
}
}
and then:
var del = new MyDelegate ();
var speech = new VSSpeechSynthesizer();
speech.WeakDelegate = del;
The support for using C# events cannot be used because it expects the
getter to work.
I hope this helps,
Rolf
