我有一个应用程序，您可以在其中找到我们大学的员工并通过电子邮件与他们联系。当你找到某人并查看详细信息时，NSUserActivity会创建一个：

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"9.0")) {
        //Create NSUserActivity for the person
        NSUserActivity * activity = [[NSUserActivity alloc] initWithActivityType:CAUserActivityTypePerson];
        activity.title = [_displayedPerson completeName];
        activity.requiredUserInfoKeys = [NSSet setWithArray:@[@"id", @"fullName"]];
        activity.userInfo = [NSDictionary dictionaryWithObjects:@[_displayedPerson.personID, [_displayedPerson completeName]] forKeys:@[@"id", @"fullName"]];


        activity.keywords = [NSSet setWithObjects:[_displayedPerson completeName], [_displayedPerson institutionString], nil];

        CSSearchableItemAttributeSet * contentAttributeSet = [[CSSearchableItemAttributeSet alloc] init];
        contentAttributeSet.contentDescription = [_displayedPerson institutionString];

        activity.contentAttributeSet = contentAttributeSet;

        //make the activity active and searchable
        self.userActivity = activity;
        self.userActivity.eligibleForHandoff = NO;
        self.userActivity.eligibleForSearch = YES;
        self.userActivity.eligibleForPublicIndexing = NO;
        self.userActivity.needsSave = YES;
        [self.userActivity becomeCurrent];
        NSLog(@"UserActivity created\nInfo: %@", self.userActivity.userInfo);
    } else
        NSLog(@"Did not create NSUserActivity! iOS 9 required!");

创建 UserActivity 时，NSLog(@"UserActivity created\nInfo: %@", self.userActivity.userInfo);返回正确的userInfo.

当我在聚光灯下找到条目（正确显示所有相关数据）并单击它时，该应用程序将被打开并被- (BOOL)application:continueUserActivity:restorationHandler:调用并userActivity包含正确的标题和类型。但是userInfo和requiredUserInfoKeys都是空的。

- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray * _Nullable))restorationHandler {

    NSLog(@"Activity: %@\nInfo: %@", userActivity.activityType, userActivity.requiredUserInfoKeys);

    return YES;
}

我不明白，我在哪里犯了错误。我已经读过这个，但它没有帮助。

PS：_displayedPerson.personID是一个NSNumber并[_displayedPerson completeName]返回一个NSString

我在 Apple Developer Forums 中找到了答案。updateUserActivityState:需要被覆盖。

- (void)updateUserActivityState:(NSUserActivity *)userActivity {
    [userActivity addUserInfoEntriesFromDictionary:@{@"id" : _displayedPerson.personID, @"fullName" : [_displayedPerson completeName]}];
}

我不知道为什么我必须这样做，但它确实有效。希望，这也会对其他人有所帮助。
