使用AirDrop时，UIActivityViewController完成处理程序已完成 [英] UIActivityViewController completion handler is !completed when using AirDrop

问题描述

我正在使用 UIActivityViewController 来分享一些文本和网址，这些文字和网址在发送一些文字和网址时效果很好。

I am using UIActivityViewController to share some text and url which works great when sending some text and a url.

我目前需要使用完成处理程序来执行其他操作，具体取决于用户是否取消了 UIActivityViewController 或实际发送了什么。

I currently need to use the completion handler to perform additional actions depending whether the user cancelled the UIActivityViewController or actually sent something.

在iOS 8中不推荐使用iOS 7的完成处理程序（ activityViewController.completionHandler ，现在 activityViewController setCompletionWithItemsHandler ）返回 BOOL已完成值，当使用 email true $ c> sms Facebook Twitter 然而当发送时 Airdrop 用户必须按取消才能在发送后关闭 UIActivityViewController 因此我总是从完成处理程序中收到 false 。

The completion handler (activityViewController.completionHandler for iOS 7 is deprecated in iOS 8 which is now activityViewController setCompletionWithItemsHandler) returns a BOOL completed value which correctly returns true when sending with email sms Facebook Twitter however when sending via Airdrop the user must press Cancel to dismiss the UIActivityViewController once sent and thus I always receive a false from the completion handler.

有谁知道是否有知道用户在 UIActivityViewController 被解雇时使用 Airdrop 发送的方式？

Does anyone know if there's a way of knowing that the user has sent using Airdrop when the UIActivityViewController is dismissed?

谢谢

推荐答案

我发现了一些你感兴趣的东西，但不幸的是我无法测试它因为AirDrop不想在我的iDevices之间运行。很抱歉。

I've found something of interest for you but unfortunately I couldn't test it as AirDrop didn't want to function between my iDevices. Sorry about that.

无论如何，您可以尝试 setCompletionWithItemsHandler 检查 activityType ：

Anyway, you could try setCompletionWithItemsHandler checking for activityType:

[activityViewController setCompletionWithItemsHandler:^(NSString *activityType, BOOL completed, NSArray *returnedItems, NSError *activityError) {
    NSLog(@"completed: %@, \n%d, \n%@, \n%@,", activityType, completed, returnedItems, activityError);

}];

如果 activityType 的类型为 com.apple.airdrop.etc （只是一个猜测）然后用户点击了图标。希望它可以提供帮助。

If activityType is of type com.apple.airdrop.etc (just a guess) then the user has tapped on the icon. Hope it can help.
