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?
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
.
完成处理程序的文档.
