/**
* @name ActionSheet
* @description
* An Action Sheet is a dialog that lets the user choose from a set of
* options. It appears on top of the app's content, and must be manually
* dismissed by the user before they can resume interaction with the app.
* Dangerous (destructive) options are made obvious in `ios` mode. There are easy
* ways to cancel out of the action sheet, such as tapping the backdrop or
* hitting the escape key on desktop.
*
* An action sheet is created from an array of `buttons`, with each button
* including properties for its `text`, and optionally a `handler` and `role`.
* If a handler returns `false` then the action sheet will not be dismissed. An
* action sheet can also optionally have a `title` and a `subTitle`.
*
* A button's `role` property can either be `destructive` or `cancel`. Buttons
* without a role property will have the default look for the platform. Buttons
* with the `cancel` role will always load as the bottom button, no matter where
* they are in the array. All other buttons will be displayed in the order they
* have been added to the `buttons` array. Note: We recommend that `destructive`
* buttons are always the first button in the array, making them the top button.
* Additionally, if the action sheet is dismissed by tapping the backdrop, then
* it will fire the handler from the button with the cancel role.
*
* You can pass all of the action sheet's options in the first argument of
* the create method: `ActionSheet.create(opts)`. Otherwise the action sheet's
* instance has methods to add options, like `setTitle()` or `addButton()`.
*
* @usage
* ```ts
* constructor(nav: NavController) {
* this.nav = nav;
* }
*
* presentActionSheet() {
* let actionSheet = ActionSheet.create({
* title: 'Modify your album',
* buttons: [
* {
* text: 'Destructive',
* role: 'destructive',
* handler: () => {
* console.log('Destructive clicked');
* }
* },
* {
* text: 'Archive',
* handler: () => {
* console.log('Archive clicked');
* }
* },
* {
* text: 'Cancel',
* role: 'cancel',
* handler: () => {
* console.log('Cancel clicked');
* }
* }
* ]
* });
*
* this.nav.present(actionSheet);
* }
* ```
