                  问题描述

                  我正在尝试使用 UIActivityViewControllerCompletionHandler ,但我不太明白如何..

                  I am trying to use the UIActivityViewControllerCompletionHandler , but i dont quite get how..

                  我想检测用户何时完成或关闭此视图控制器(UIActivityViewController).

                  I want to detect when the user finishes or dismisses this view controller (UIActivityViewController).

                  有人知道怎么做吗?

                  推荐答案

                  typedef void (^UIActivityViewControllerCompletionHandler)
                      (NSString *activityType, BOOL completed);
                  

                  完成处理程序的第二个参数告诉您用户是否关闭了控制器.如果他们解除了控制器,completed 将设置为 NO.

                  The second parameter of the completion handler tells you whether the user dismissed the controller. If they dismissed the controller, completed will be set to NO.
