Action Sheet (ActionSheet)
An action sheet is a dialog box that displays actions a user can take.
NOTE
The APIs of this module are supported since API version 8. Updates will be marked with a superscript to indicate their earliest API version.
The functionality of this module depends on UI context. This means that the APIs of this module cannot be used where the UI context is unclear. For details, see UIContext.
Since API version 10, you can use the showActionSheet API in UIContext, which ensures that the action sheet is shown in the intended UI instance.
