NSUserActivity没有在osx上建立索引

Question

我试图在OSX10.11上添加我自己的活动到Spotlight搜索结果中。但是经过多次尝试，我无法进入Spotlight搜索结果--不是关键字搜索，也不是标题搜索。

{
    self.userActivity = [[NSUserActivity alloc] initWithActivityType:@"Reverse DNS keyword"];

    self.userActivity.title = @"Some title";
    self.userActivity.keywords = [NSSet setWithArray: @[@"Some keywords"]];
    self.userActivity.eligibleForSearch = YES;
    self.userActivity.eligibleForHandoff = YES;
    self.userActivity.eligibleForPublicIndexing = YES;
    self.userActivity.userInfo = @{@"name" : @"Some name"};
    self.userActivity.delegate = self;
    self.userActivity.requiredUserInfoKeys =[NSSet setWithArray: @[@"name"]];
    self.userActivity.needsSave = YES;

    [self.userActivity becomeCurrent];

    NSApp.userActivity = self.userActivity;
}

- (void)userActivityWillSave:(NSUserActivity *)userActivity
{
     userActivity.userInfo = @{@"name" : @"Some name"};
}

此外，我还从Info.plist :参数中用NSUserActivityTypes数组和项更新了initWithActivityType

我还注意到，在控制台中有时会出现消息：

16/09/2016 13:14:49.731 Caching encoded userInfo to use until we are marked dirty again (UAUserActivity.m #1567)
16/09/2016 13:14:49.731 Returning cached encoded userInfo (UAUserActivity.m #1508)

Answer 1

经过多次搜索，我终于在TN2416上找到了我的问题的答案

**Are these new Search APIs available on OS X?**

CoreSpotlight and the search functionality of NSUserActivity are not supported on OS X.  However, web search results may be shown on OS X.
