Core Spotlight, continueUserActivity in objective-c?

iOS 9.2, xCode 7.2, Objective-C

I used this tutorial (Core Spotlight version) but translated it into Objective-C: http://code.tutsplus.com/tutorials/ios-9-introducing-search-apis--cms-24375

Everything works except one thing - I can't get callback when user taps the search result. It seems I need to write the following method in my app delegate:

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

But it is not called at all. How to solve this issue?

Solution

  • You have to first check your activity has type search action :

    - (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void(^)(NSArray * __nullable restorableObjects))restorationHandler 
{
    if ([[userActivity activityType] isEqualToString:CSSearchableItemActionType]) 
    {
        NSString *uniqueIdentifier = [userActivity.userInfo objectForKey:CSSearchableItemActivityIdentifier];
        NSLog(@"%@",uniqueIdentifier);
        // Launch Detail controller
    }
return YES;
}

    Hope it helps you!!
