确定使用了哪个共享扩展程序 [英] Determine which share extension was used

问题描述

由于在iOS 8中已经弃用了 completionHandler on UIActivityViewController ，是否有任何方法来确定哪个共享扩展/活动是由用户使用的？

Since the completionHandler on UIActivityViewController was deprecated in iOS 8, is there any way to determine which share extension/activity was used by the user?

推荐答案

您只需要使用新的处理程序 UIActivityViewControllerCompletionWithItemsHandler ：

You just need to use the new handler UIActivityViewControllerCompletionWithItemsHandler:

typedef void (^UIActivityViewControllerCompletionWithItemsHandler)(NSString *activityType, BOOL completed, NSArray *returnedItems, NSError *activityError);

这样调用：

[yourActivityVC setCompletionWithItemsHandler:^(NSString *activityType, BOOL completed, NSArray *returnedItems, NSError *activityError){

}];

此外，如果您想知道选择了什么项目，您只需要确保您的活动项目符合 UIActivityItemSource 协议;

Additionally, if you're wondering about knowing what item was selected, you just need to ensure your activity items conform to the UIActivityItemSource protocol;
