弄清楚在UIActivityViewController中点击了哪个图标 [英] Figuring out which icon was clicked on in UIActivityViewController

问题描述

使用社交框架，在展示显示所有常用社交媒体图标的模式UIActivityViewController时，有没有办法找出用户点击的确切图标？意思是，如果他们选择Twitter，Facebook，Mail，Message等？

Using the "Social" Framework, when presenting the modal UIActivityViewController that displays all the usual social-media icons, is there a way to find out exactly which icon the user clicked on? Meaning, if they chose Twitter, Facebook, Mail, Message, etc?

我原本希望在Docs中看到这个类的一些委托方法，但我什么都看不到。

I was expecting to possibly see some delegate methods for this class in the Docs but I don't see anything.

有人有任何想法吗？

推荐答案

UIActivityViewController 有 completionHandler 属性。实现此处理程序以通知。

The UIActivityViewController has the completionHandler property. Implement this handler to be notified.

UIActivityViewController *avc = ...;
avc.completionHandler = ^(NSString *activityType, BOOL completed) {
    if (completed) {
        NSLog(@"The selected activity was %@", activityType);
    }
};
