ipad - Accidente de UIActionSheet en iOS8beta

xcode5

Question

Tengo un código que simplemente muestra UIActionSheet al hacer clic en el botón. pero se bloqueará cuando lo construya usando XCode5.1 + iOS8beta en iPad.

a continuación se muestra un código que utilicé para mostrar UIActionSheet.

UIActionSheet *tmpActionSheet = [[UIActionSheet alloc] initWithTitle:nil
                                                                delegate:self
                                                       cancelButtonTitle:@"Cancel"
                                                  destructiveButtonTitle:nil
                                                       otherButtonTitles:
                                     @"Ok",
                                     nil];
    [tmpActionSheet showInView:self.view];

Nota:
- Funciona perfectamente con XCode6beta + iOS8beta (iPhone / iPad ambos)
- Funciona perfectamente con XCode5.1 + iOS8beta (solo iPhone)

Answer 1

Estoy teniendo el mismo problema, y ​​esto todavía está "roto" en la versión beta 5. En mi caso, solo estoy obteniendo una pantalla atenuada sin hoja de acción en lugar de una falla.

Excepto que mostrar una hoja de acción directamente en una vista en iPad no es un buen diseño de todos modos. Debes usar popover que contenga una hoja de acción y apuntar al botón o elemento de UI que generó la opción como sugirió Sabareesh. Las alertas son para mensajes que están desconectados de cualquier elemento de la interfaz de usuario, las hojas de acción siempre están asociadas con un elemento de interfaz de usuario en pantalla hasta donde yo sé.

Answer 2

También tuve el mismo problema. utilicé la función ShowFromBarButtonItem en lugar de la función ShowInView.

[organizeActionSheet showFromBarButtonItem:btnAction animated:NO];

si no se aplica la excepción de tiempo de ejecución ShowFromRect o showFromBarButtonItem . Creo que es un error de IOS8 Beta, cuando uso la excepción ShowInView Runtime se acerca.

Este error no está sucediendo en IOS Beta 4 ..

Obtengo algunos mensajes de advertencia en la ventana de depuración cuando se construye usando Xcode 5.1, pero la hoja de acción aparece. En iOS 8 beta 4, aparece como una pequeña ventana emergente fuera de la vista (en el lateral), mientras que en iOS 7, solía aparecer como botones que se deslizaban desde la parte inferior de la vista.

Answer 3

He visto el mismo problema por un tiempo con showInView que no funciona desde IOS 8 Beta 2 hasta Beta 5. Acabo de enviar el informe de errores: 17971746.

Answer 4

También sufro un colapso en iOS8 final en iPad.

Esta es mi solución simple:
reemplazar
[actionSheet showFromBarButtonItem:myButton animated:YES];
por
[actionSheet showFromRect:myButton.navBarView.frame inView:self.view animated:YES];
