Monotouch iOS 6 falla al usar MFMailComposeViewController (1)

Me sale un error extraño cuando uso MFMailComposeViewController en Monotouch iOS 6, pero funcionó bien en iOS 5.1:

*** Assertion failure in NSDictionary *_UIRecordArgumentOfInvocationAtIndex(NSInvocation *, NSUInteger, BOOL)(), /SourceCache/UIKit/UIKit-2372/UIAppearance.m:1118

Aquí está el código:

MFMailComposeViewController _mail; public void SendFeedbackMail (string email_subject, string email_message_body, string[] email_recipients) { if (MFMailComposeViewController.CanSendMail) { _mail = new MFMailComposeViewController (); _mail.SetSubject (email_subject); _mail.SetToRecipients (email_recipients); _mail.SetMessageBody (email_message_body + "/n", false); _mail.Finished += HandleMailFinished; root_controller.PresentViewController(_mail, true, null); } else { //handle not being able to send mail UIAlertView alert = new UIAlertView ("Mail Alert", "Error: Check your eMail configuration", null, "OK", null); alert.Show (); } }

Cualquier ayuda es apreciada. Gracias.

ACTUALIZAR:

Desafortunadamente, parece que hay más de un error aquí.

En mi caso, el bloqueo del Mail Composer no fue causado por una Apariencia o una cadena atribuida. Probé todas las conexiones posibles, pero mi código falla.

Así que empecé a comentar todo mi código línea por línea, y lo crucé:

Es el código de compra In App.

Estoy usando el código de la muestra En la compra de la aplicación en el sitio web de xamarin.

Si comento solo esta línea usando la clase SKProductRequest:

productsRequest.Start ();

¡MFMailComposer se abre y funciona perfectamente bien!

Así que probé MFMailComposer en el proyecto de muestra original de Xamarin:

http://docs.xamarin.com/ios/tutorials/In-App_Purchasing http://docs.xamarin.com/@api/deki/files/3300/=InAppPurchaseSample.zip

Acabo de agregar este código a la clase NonConsumableViewController:

/// <summary> /// TEST MAIL COMPOSER BUG - START /// </summary> MFMailComposeViewController _mail; void HandleFinished (object sender, MFComposeResultEventArgs e) { } public void TestMailComposer () { var button = UIButton.FromType(UIButtonType.RoundedRect); button.Frame = new RectangleF(20f, 0f, 280f, 40f); button.TouchUpInside += (object sender, EventArgs e) => { if (MFMailComposeViewController.CanSendMail) { _mail = new MFMailComposeViewController (); _mail.SetSubject ("The Subject"); _mail.SetToRecipients (new [] {"[email protected]"}); _mail.SetMessageBody ("Some text to e-mail stuff too" + "/n", false); _mail.Finished += HandleFinished; this.PresentViewController(_mail, true, null); } else { //handle not being able to send mail UIAlertView alert = new UIAlertView ("Mail Alert", "Error: Check your eMail configuration", null, "OK", null); alert.Show (); } }; button.SetTitle("Button", UIControlState.Normal); View.AddSubview(button); } /// /// TEST MAIL COMPOSER BUG - END ///

Y cuando presiono el botón se cuelga.

ACTUALIZAR:

Probé la revisión 6.0.2 (disculpe la espera, pero tuve que revertir mi código al estado original). El error de apariencia ya no está.

El problema con la clase SKProductRequest parece diferente y menos urgente. No cuelga, solo demora la apertura del compositor de MF Mail por un tiempo. Pero esto parece un error no relacionado.

Esta es la referencia de error: https://bugzilla.xamarin.com/show_bug.cgi?id=7443

Esto podría ayudar (del error Xamarin)

cancelAttributes = new UITextAttributes(); //cancelAttributes.TextShadowOffset = new UIOffset(0, -1); cancelAttributes.TextShadowColor = UIColor.White.ColorWithAlpha(0.5f); cancelAttributes.TextColor = Resources.CancelButtonDisabled; UIBarButtonItem.AppearanceWhenContainedIn(typeof(UISearchBar)).SetTitleTextAttributes(cancelAttributes, UIControlState.Disabled);

Me sale el problema si tengo el bit comentado en mi código, pero no si está comentado. ¿Estás usando el material de UIAppearance?
