问题描述

Id like to be able to track if the user shared by facebook, twitter, etc, but it seems there's no way to know which method was selected. Is there?

推荐答案

你可以在 setCompletionHandler 中使用 Activity Types

You can use Activity Types in setCompletionHandler

UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:nil];

[activityVC setCompletionHandler:^(NSString *activityType, BOOL completed) {
    if([activityType isEqualToString: UIActivityTypeMail]){
        NSLog(@"Mail");
    }
    if([activityType isEqualToString: UIActivityTypePostToFacebook]){
        NSLog(@"Facebook");
    }

}];
[self presentViewController:activityVC animated:TRUE completion:nil];

系统内置支持的内置活动类型.

Built-in activity types for which the system has built-in support for.

NSString *const UIActivityTypePostToFacebook;

NSString *const UIActivityTypePostToTwitter;

NSString *const UIActivityTypePostToWeibo;

NSString *const UIActivityTypeMessage;

NSString *const UIActivityTypeMail;

NSString *const UIActivityTypePrint;

NSString *const UIActivityTypeCopyToPasteboard;

NSString *const UIActivityTypeAssignToContact;

NSString *const UIActivityTypeSaveToCameraRoll;

为 iOS 8 编辑

请注意，这会在 iOS 8 中生成编译器警告，您需要使用 setCompletionWithItemsHandler 方法而不是 setCompletionHandler 方法.

Please note that this will generate a compiler warning in iOS 8, you need to use the setCompletionWithItemsHandler method instead of the setCompletionHandler method.

替换:

[activityVC setCompletionHandler:^(NSString *activityType, BOOL completed) {

与:

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