1. Create a new iOS project and add CoreSpotlight and MobileCoreServices framework to your project.

   创建一个新的iOS项目，并将CoreSpotlight和MobileCoreServices框架添加到项目中。

2. Create the actual CSSearchableItem and associating the uniqueIdentifier, domainIdentifier and the attributeSet. Finally index the CSSearchableItem using [[CSSearchableIndex defaultSearchableIndex]...] as show below.

   创建实际的CSSearchableItem并关联惟一标识符、domainIdentifier和attributeSet。最后使用[CSSearchableIndex defaultSearchableIndex]索引CSSearchableItem。如下显示。

3. OK!Test the index!
   

   好的!测试该指数!

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");
}];

Note: kUTTypeImage requires that you import the MobileCoreServices framework.

注意:kUTTypeImage要求您导入MobileCoreServices框架。

To complete the spotlight search functionality, once you have implemented mayqiyue's answer, you'll be able to see the results in the search but on selection of the result simply your app would open not the related view with related content.

为了完成spotlight的搜索功能，一旦您实现了mayqiyue的答案，您将能够在搜索中看到结果，但是在选择结果时，您的应用程序将不会打开与相关内容相关的视图。

In order to do so, go to your AppDelegate.m and add the following method.

要这样做，请转到AppDelegate。m并添加以下方法。

 -(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;
        }

Make sure to import in AppDelegate.m :

确保导入AppDelegate。m:

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

UPDATE for Swift 2.1

2.1更新迅速

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

}

I am using similar implementation as mentioned by @mayqiyue but I am also checking the existence of the item variable for backwards compatibility with iOS 8.

我正在使用@mayqiyue提到的类似实现，但我也在检查item变量是否存在，以便与iOS 8向后兼容。

- (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", @"*", @"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");
            }
        }];
    }
}

To handle the tap on the search item from Spotlight you need to implement following method in your AppDelegate:

要处理Spotlight搜索项的点击，您需要在AppDelegate中实现以下方法:

- (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;
}

1. Write in your main controller Class

   写入主控制器类

   -(void)storeValueForSpotligtSearch {
   
       NSString *bundleIdentifier                      = [[NSBundle mainBundle] bundleIdentifier];
       // **Your Model Array that Contain Data Like attributes Make, Model, Variant and Year and Images**
   
       for (MyCatalogeModel *myCatalogeModelObj in yourDataContainer) {
           NSMutableArray *arrKeywords                 = [[NSMutableArray alloc] initWithObjects: myCatalogeModelObj.year, myCatalogeModelObj.make, myCatalogeModelObj.model, myCatalogeModelObj.variant, nil];
           NSString *strIdentifier                     = [NSString stringWithFormat:@"%@.%@",bundleIdentifier, myCatalogeModelObj.carId];
           self.userActivity                           = [[NSUserActivity alloc]initWithActivityType:strIdentifier];
           self.userActivity.title                     = myCatalogeModelObj.year;
           self.userActivity.title                     = myCatalogeModelObj.make;
           self.userActivity.title                     = myCatalogeModelObj.model;
           self.userActivity.title                     = myCatalogeModelObj.variant;
           self.userActivity.eligibleForSearch         = YES;
           self.userActivity.eligibleForPublicIndexing = YES;
           self.userActivity.eligibleForHandoff        = YES;
           CSSearchableItemAttributeSet * attributeSet = [[CSSearchableItemAttributeSet alloc] initWithItemContentType:(NSString *)kUTTypeJSON];
           attributeSet.title                          = myCatalogeModelObj.make;
           attributeSet.thumbnailData                  = [NSData dataWithContentsOfURL:[NSURL URLWithString:[myCatalogeModelObj.imageArray objectAtIndex:0]]];
           attributeSet.contentDescription             = [NSString stringWithFormat:@"%@ %@ %@ %@", myCatalogeModelObj.year, myCatalogeModelObj.make, myCatalogeModelObj.model, myCatalogeModelObj.variant];
           attributeSet.keywords                       = arrKeywords;
           CSSearchableItem *item                      = [[CSSearchableItem alloc] initWithUniqueIdentifier:strIdentifier domainIdentifier:@"spotlight.CARS24ChannelPartnerapp" attributeSet:attributeSet];
           [[CSSearchableIndex defaultSearchableIndex] indexSearchableItems:@[item] completionHandler: ^(NSError * __nullable error) {
           }];
           self.userActivity.contentAttributeSet       = attributeSet;
           [self.userActivity becomeCurrent];
           [self updateUserActivityState:self.userActivity];
       }
   }
   

2. Write in App Delegate

   写在应用程序委托

   -(BOOL)application:(nonnull UIApplication *) application continueUserActivity:(nonnull NSUserActivity *)userActivity restorationHandler:(nonnull void (^)(NSArray * __nullable))restorationHandler {
   
       @try {
   
           NSString *strIdentifier;
           NSNumber *numScreenId;
           NSNumberFormatter *numFormatter = [[NSNumberFormatter alloc] init];
           NSLog(@"Activity = %@",userActivity.userInfo);
           if (userActivity.userInfo[@"vc"]) {
               numScreenId = userActivity.userInfo[@"vc"];
           }
           else{
               strIdentifier = [userActivity.userInfo objectForKey:@"kCSSearchableItemActivityIdentifier"];
               NSLog(@"strIdentifier : %@",strIdentifier);
               NSArray *arr = [strIdentifier componentsSeparatedByString:@"."];
               NSString *strScreenId = [arr objectAtIndex:3];
               NSLog(@"ID -= %@",strScreenId);
   
               **// On Click in Spotlight search item move your particular view.**
   
               [self moveToParticular:[strScreenId intValue]];
               numScreenId = [numFormatter numberFromString:strScreenId];
           }
       }
       @catch (NSException *exception) {}
   
       return YES;
   }
