是否有corepotlight搜索功能的示例代碼 - iOS 9 API？

CSSearchableItemAttributeSet *attributeSet; 
attributeSet = [[CSSearchableItemAttributeSet alloc] 
           initWithItemContentType:(NSString *)kUTTypeImage]; 

attributeSet.title = @"My First Spotlight Search"; 
attributeSet.contentDescription = @"This is my first spotlight Search"; 

attributeSet.keywords = @[@"Hello", @"Welcome",@"Spotlight"]; 

UIImage *image = [UIImage imageNamed:@"searchIcon.png"]; 
NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(image)]; 
attributeSet.thumbnailData = imageData; 

CSSearchableItem *item = [[CSSearchableItem alloc] 
             initWithUniqueIdentifier:@"com.deeplink" 
               domainIdentifier:@"spotlight.sample" 
                attributeSet:attributeSet]; 

[[CSSearchableIndex defaultSearchableIndex] indexSearchableItems:@[item] 
           completionHandler: ^(NSError * __nullable error) { 
    if (!error) 
     NSLog(@"Search item indexed"); 
}];

注意：kUTTypeImage要求您導入MobileCoreServices框架。

感謝您的代碼段。 –

看起來不對。 ''com.deeplink''實際上應該是一個唯一的標識符，它唯一標識了你正在建立索引的對象（比如數據庫中的主ID，GUUID或其他）。 CSSearchableItemAttributeSet上的'kUTTypeImage'是您需要設置深層鏈接的地方。蘋果在主題演講中展示的例子實際上是錯誤的，並不一致，但正確的例子可以在視頻的前面看到。 – strangetimes

創建一個新的iOS項目，並添加CoreSpotlight和MobileCoreServices框架到您的項目。
創建實際的CSSearchableItem並關聯uniqueIdentifier，domainIdentifier和attributeSet。最後使用[[CSSearchableIndex defaultSearchableIndex] ...]對CSSearchableItem進行索引，如下所示。
行！測試索引！

很好的答案。但是，您應該包括開發人員在用戶選擇並編制索引後如何實施行動方案。 – soulshined

HAHA，因爲大多數提問者只是不知道如何從CoreSpotlight搜索API開始。這裏只是一個簡單的指南。 – mayqiyue

我並不是一個開玩笑的人。這是一個很好的答案，但沒有完成對這個問題的真實答案的要素。爲將來的問題提供者包括將是一件好事。 – soulshined

我使用類似的實現如由@mayqiyue提及，但我也檢查item變量的向後兼容性的存在與iOS 8.

- (void)setupCoreSpotlightSearch 
{ 
    CSSearchableItemAttributeSet *attibuteSet = [[CSSearchableItemAttributeSet alloc] initWithItemContentType:(__bridge NSString *)kUTTypeImage]; 
    attibuteSet.title = NSLocalizedString(@"Be happy!", @"Be happy!"); 
    attibuteSet.contentDescription = @"Just like that"; 
    attibuteSet.keywords = @[@"example", @"stackoverflow", @"beer"]; 

    UIImage *image = [UIImage imageNamed:@"Image"]; 
    NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(image)]; 
    attibuteSet.thumbnailData = imageData; 

    CSSearchableItem *item = [[CSSearchableItem alloc] initWithUniqueIdentifier:@"1" 
                  domainIdentifier:@"album-1" 
                   attributeSet:attibuteSet]; 
    if (item) { 
     [[CSSearchableIndex defaultSearchableIndex] indexSearchableItems:@[item] completionHandler:^(NSError * _Nullable error) { 
      if (!error) { 
       NSLog(@"Search item indexed"); 
      } 
     }]; 
    } 
}

要在處理抽頭從Spotlight搜索項目，您需要在AppDelegate中執行以下方法：

- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray * _Nullable))restorationHandler 
{ 
    if ([userActivity.activityType isEqualToString:CSSearchableItemActionType]) { 
     NSString *uniqueIdentifier = userActivity.userInfo[CSSearchableItemActivityIdentifier]; 

     // Handle 'uniqueIdentifier' 
     NSLog(@"uniqueIdentifier: %@", uniqueIdentifier); 
    } 

    return YES; 
}

要完成聚光燈搜索功能，一旦您實施了mayqiyue's答案，您將能夠在搜索中看到結果，但在結果的選擇上，只是您的應用不會打開與相關內容相關的視圖。

爲了達到目的，請轉到您的AppDelegate.m並添加以下方法。

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

     { 

      //check if your activity has type search action(i.e. coming from spotlight search) 
      if ([userActivity.activityType isEqualToString:CSSearchableItemActionType ] == YES) { 

       //the identifier you'll use to open specific views and the content in those views. 
       NSString * identifierPath = [NSString stringWithFormat:@"%@",[userActivity.userInfo objectForKey:CSSearchableItemActivityIdentifier]]; 

       if (identifierPath != nil) { 

        // go to YOUR VIEWCONTROLLER 
        // use notifications or whatever you want to do so 

        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil]; 
        MyViewController *myViewController = [storyboard instantiateViewControllerWithIdentifier:@"MyViewController"]; 

        // this notification must be registered in MyViewController 
        [[NSNotificationCenter defaultCenter] postNotificationName:@"OpenMyViewController" object: myViewController userInfo:nil]; 


        return YES; 
       } 

      } 


      return NO; 
     }

確保進口在AppDelegate.m：

#import <MobileCoreServices/MobileCoreServices.h> 
#import <CoreSpotlight/CoreSpotlight.h>

更新雨燕2.1

func application(application: UIApplication, continueUserActivity userActivity: NSUserActivity, restorationHandler: ([AnyObject]?) -> Void) -> Bool { 

    if #available(iOS 9.0, *) { 
     if userActivity.activityType == CSSearchableItemActionType { 

      //the identifier you'll use to open specific views and the content in those views. 
      let dict = userActivity.userInfo! as NSDictionary 
      let identifierPath = dict.objectForKey(CSSearchableItemActivityIdentifier) as! String 
      if identifierPath.characters.count > 0 { 

       let storyboard : UIStoryboard = UIStoryboard(name: "Main", bundle: nil) 
       let mvc: MyViewController = storyboard.instantiateViewControllerWithIdentifier("MyViewController") as! MyViewController 

       NSNotificationCenter.defaultCenter().postNotificationName("OpenMyViewController", object: mvc, userInfo: nil) 
      } 

      return true 
     } 

    } else { 
     // Fallback on earlier versions 
      return false 

    } 

    return false 

}

確保進口在AppDelegate中。SWIFT：

import MobileCoreServices

let attributeSet = CSSearchableItemAttributeSet(itemContentType: kUTTypeImage as String) 
attributeSet.title = "Searchable Item" 
attributeSet.contentDescription = "Code for creating searchable item"
