Hi guys,
I am seeing a problem where calling InvokeOnMainThread is hanging in
certain parts of the code. I thought maybe the problem might be because the
code is already running on the main thread, but based on the following code,
it wasn't. The code is hanging on the InvokeOnMainThread and execution never
hits the this.progressHUD.Hide(true) line. Any ideas why this might be the
case?
thanks,
Dennis
public void HideProgressIndicator()
{
if (this.progressHUD != null)
{
if (!IsMainThread())
this.InvokeOnMainThread(()=>{
this.progressHUD.Hide(true);
});
else
this.progressHUD.Hide(true);
}
}
protected static bool IsMainThread() {
return Messaging.bool_objc_msgSend(GetClassHandle("NSThread"),
new Selector("isMainThread").Handle);
}
protected static IntPtr GetClassHandle (string clsName)
{
return (new Class(clsName)).Handle;
}
