En el ejemplo de código siguiente se muestra el comportamiento del IsSubsetOf método . Este ejemplo forma parte de un ejemplo más grande proporcionado para la UIPermission clase .

// IsSubsetOf determines whether the current permission is a subset of the specified permission.

Comentarios

El permiso actual es un subconjunto del permiso especificado si todas las demandas que se realizan correctamente para el permiso actual también se realizan correctamente para el permiso especificado. Es decir, el permiso especificado contiene al menos los permisos contenidos en el subconjunto. Para IsSubsetOf que devuelva true, los UIPermissionWindow valores y UIPermissionClipboard del permiso actual deben ser iguales o menos permisivos que los valores del permiso especificado.
