[MonoTouch] NetworkActivityIndicatorVisible with MonoTouch.Dialog

[Dean Cleaver]

2 ideas.... I've seen problems when executing code on the UI thread right after a call to a UI element (also check that you are calling this on the main/UI thread).

#1
UIApplication.SharedApplication.NetworkActivityIndicatorVisible = true;
StyledStringElement btnLogin = new StyledStringElement("Login", delegate { DoLogin(); });

public void DoLogin()
{
  try {
    ... do work
  }
  finally {
    UIApplication.SharedApplication.NetworkActivityIndicatorVisible = false;
  }
}

#2

StyledStringElement btnLogin = new StyledStringElement("Login", delegate { DoLogin(); });

public void DoLogin()
{
  UIApplication.SharedApplication.NetworkActivityIndicatorVisible = true;
  NSRunLoop.Current.RunUntil(DateTime.Now.AddMilliseconds(1));
  try {
    ... do work
  }
  finally {
    UIApplication.SharedApplication.NetworkActivityIndicatorVisible = false;
  }
}

Subject: [MonoTouch] NetworkActivityIndicatorVisible with MonoTouch.Dialog

Has anyone got the NetworkActivityIndicatorVisible to work on the device while using MonoTouch.Dialog?

I create a button like this:

StyledStringElement btnLogin = new StyledStringElement("Login", delegate { DoLogin(); });

When I click the button it does take me to this method:
public void DoLogin()
{
  UIApplication.SharedApplication.NetworkActivityIndicatorVisible = true;
  try {
    ... do work
  }
  finally {
    UIApplication.SharedApplication.NetworkActivityIndicatorVisible = false;
  }
}

The spinning indicator doesn't show up. I've tried while debugging and tethered via USB, and also by just running the app with a wifi connection.

I'm using MT 5.2.

Anyone seeing the same thing? Anything look obviously wrong?

Thanks
