У меня есть простое тестовое приложение с NavigationController, которое расширяет UINavigationController
[MonoTouch.Foundation.Register("NavigationController")]
public class NavigationController : UINavigationController
{
public NavigationController (IntPtr handle) : base (handle)
{
}
[Export ("initWithCoder:")]
public NavigationController (NSCoder coder) : base (coder)
{
}
public NavigationController (UIViewController rootViewController) : base(rootViewController)
{
}
public override void ViewDidLoad ()
{
base.ViewDidLoad ();
View.BackgroundColor = UIColor.Green;
}
}
У меня также есть CustomersTableViewController, который расширяет UITableViewController (здесь Source не влияет). В методе ViewDidLoad я создаю UISearchBar и добавляю его в TableHeaderView.
public class CustomersTableViewController : UITableViewController
{
UISearchBar _searchBar;
public CustomersTableViewController(UITableViewStyle style) : base(style)
{
}
public override void ViewDidLoad ()
{
base.ViewDidLoad ();
_searchBar = CreateSearchBar ();
_searchBar.SearchButtonClicked += OnSearchBarSearchButtonClicked;
TableView.TableHeaderView = _searchBar;
}
void OnSearchBarSearchButtonClicked (object sender, EventArgs e)
{
}
static UISearchBar CreateSearchBar ()
{
UISearchBar search = new UISearchBar ();
search.Placeholder = "Search Customers";
search.SizeToFit ();
search.AutocorrectionType = UITextAutocorrectionType.No;
search.AutocapitalizationType = UITextAutocapitalizationType.None;
return search;
}
}
В Main.cs я запускаю следующий фрагмент кода. Если я создаю navigationController по коду или через xib, то это тоже самое.
// The name AppDelegate is referenced in the MainWindow.xib file.
public partial class AppDelegate : UIApplicationDelegate
{
// This method is invoked when the application has loaded its UI and its ready to run
public override bool FinishedLaunching (UIApplication app, NSDictionary options)
{
// If you have defined a view, add it here:
//window.AddSubview (navigationController.View);
NavigationController navigationController = new NavigationController(new CustomersTableViewController(UITableViewStyle.Plain));
window.AddSubview (navigationController.View);
window.MakeKeyAndVisible ();
return true;
}
}
Графический интерфейс отображается правильно, но когда я нажимаю на панели поиска, приложение вылетает со следующей ошибкой.

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

Есть предложения? Это ошибка MT? Я что-то пропустил? Заранее спасибо.
EDIT:
Я бегу MT 4.2.2 с Mono 2.10.4. Авария сохраняется и с Mono 2.10.5.
