You have two choices, both involves using dismissModalViewController.
您有两种选择，都涉及使用dismissModalViewController。
The preferred way is to use delegation and tell the view controller who was responsible for presenting the view to dismiss it. The other way is to have the view who was presented to dismiss itself (which actually asks the parent to dismiss it.)
首选的方法是使用委托并告诉负责呈现视图的视图控制器关闭它。另一种方法是让被呈现的视图自行驳回（实际上要求父母驳回它。）
