ios - UIActivityViewController 的最佳实践

Question

关于最佳实践，当使用完 UIActivityViewController 时，是否应该将它从使用委托(delegate)模式呈现它的 viewController 中关闭？

当模态呈现其他 ViewController 时，我总是使用委托(delegate)模式来确保父(或呈现)viewController 也进行解散 - 我相信这是最佳实践，所以我想知道这是否适用于此？

来自docs :

Your app is responsible for configuring, presenting, and dismissing this view controller. Configuration for the view controller involves specifying the data objects on which the view controller should act. (You can also specify the list of custom services your app supports.) When presenting the view controller, you must do so using the appropriate means for the current device. On iPad, you must present the view controller in a popover. On iPhone and iPod touch, you must present it modally.

所以，回答您的问题，是。您应该像对待该 View Controller 一样对待它。
