Question

我有一个应用程序，您可以在我们的大学找到员工通过电子邮件与他们联系。当您找到某人并查看详细信息时，会创建NSUserActivity：

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!");

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

当我在聚光灯下找到该条目（正确显示所有相关数据）并单击它时，将打开该应用并调用- (BOOL)application:continueUserActivity:restorationHandler:并且userActivity包含正确的标题和类型。但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;
}

我不知道，我犯了错误。我已经阅读了this，但它没有帮助。

PS：_displayedPerson.personID是NSNumber而[_displayedPerson completeName]返回NSString

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

updateUserActivityState:

我不知道，为什么我必须这样做，但它确实有效。希望，这也将有助于其他人。

无法恢复NSUserActivity的userInfo
