创建一个新的 iOS 项目并将CoreSpotlight和MobileCoreServices框架添加到您的项目中。
创建实际的 CSSearchableItem 并关联 uniqueIdentifier、domainIdentifier 和 attributeSet。最后使用 [[CSSearchableIndex defaultSearchableIndex]...] 对 CSSearchableItem 进行索引，如下所示。
OK！测试索引！

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需要您导入 MobileCoreServices 框架。

要完成聚光灯搜索功能，一旦您实现了 mayqiyue 的答案，您将能够在搜索中看到结果，但在选择结果时，您的应用程序将不会打开包含相关内容的相关视图。
为此，请转到您的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;
}
确保导入 AppDelegate.m：
#import <MobileCoreServices/MobileCoreServices.h>
#import <CoreSpotlight/CoreSpotlight.h>
更新 Swift 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
}
确保导入 AppDelegate.swift：
import CoreSpotlight
import MobileCoreServices

我正在使用@mayqiyue 提到的类似实现，但我也在检查item变量的存在是否与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", @"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");
}
}];
}
}
要处理 Spotlight 中对搜索项的点击，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;
}

写在你的主控制器类
-(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]; } }在 App Delegate 中写入
-(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; }

let attributeSet = CSSearchableItemAttributeSet(itemContentType: kUTTypeImage as String)
attributeSet.title = "Searchable Item"
attributeSet.contentDescription = "Code for creating searchable item"
attributeSet.keywords = ["Item","Searchable","Imagine"]
attributeSet.thumbnailURL = NSURL(string: "https://blog.imagine.com/")
let searchableItem = CSSearchableItem(uniqueIdentifier: "com.imagine.objectA", domainIdentifier: "spotlight.search", attributeSet: attributeSet)
CSSearchableIndex.defaultSearchableIndex().indexSearchableItems([searchableItem]) {_ in}
