Question

是否有针对corespotlight搜索功能的示例代码 - iOS 9 API？真的很感激，如果可以查看示例代码来实现/测试。

Answer 1

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] ...]索引CSSearchableItem，如下所示。
好！测试索引！

Answer 2

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要求您导入MobileCoreServices框架。

要完成聚光灯搜索功能，一旦您实施了 mayqiyue's 答案，您就可以在搜索中看到结果，但只需选择结果应用程序将打开相关内容的相关视图。

要执行此操作，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;
        }

确保导入AppDelegate.m ：

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

Swift 2.1的更新

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");
            }
        }];
    }
}

要处理从Spotlight搜索项目的点击，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;
}

Answer 5

在您的主控制器类中写入

-(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;
}

Answer 6

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}
