Thank you very much,
actually I solved the problem moving only the controllers in AppDelegate
and MyController (that is, _navCtrl and menuCtrl): since references of
views, toolbar, etc. are retained by the controllers the GC should not
remove them when the scopes terminate.
Thank you again!

ignore the bit about __mt_window :) I thought you were using a XIB and
a partial class, which does this for you. (ie, how the default
template does it)

Try moving all the declarations out of FinishedLaunching, eg:
private MonoTouch.UIKit.UIWindow __mt_window;
private UITextField _txtField;
THEY should be here!
MyController ctrl1;
UIView mainView;
UIToolbar toolbar;
public override bool FinishedLaunching (UIApplication app,
NSDictionary
options)
{
__mt_window = new UIWindow(UIScreen.MainScreen.Bounds);
__mt_window.BackgroundColor = UIColor.White;
why are you using __mt_window? use the window property, which talks to
MyController ctrl1 = new MyController();
UIView mainView = new UIView(UIScreen.MainScreen.Bounds);
NOT HERE!
UIToolbar toolbar = new UIToolbar(new RectangleF(0, 0,
320, 30));
toolbar.Items = new[]
{
new
UIBarButtonItem(UIBarButtonSystemItem.FlexibleSpace),
new UIBarButtonItem(UIBarButtonSystemItem.Done,
HandleDoneButton)
};
OR HERE - move UIToolbar out into a class-level variable
Native stacktrace:
0 MTFailure 0x000d5c18
mono_handle_native_sigsegv + 408
SIGSEGV is a Signal for a Segment Violation.
AKA a Null Pointer Exception.
All those things above will be getting GC'ed before you get to use
them. The GC in the newer version of MT is (I beleive) a LOT more
agressive, so things going out of scope get cleaned up quickly.
Putting them in as class var's stops that.
