简单些了一下，有不足往谅解。

什么是shortcut?

简单说就是往Sir里添加一条语音指令，通过Siri呼出指令后，打开对应的app，并跳转到指定页面。

如何集成

• 头文件依赖

#import <CoreSpotlight/CoreSpotlight.h>
#import <IntentsUI/IntentsUI.h>
#import <Intents/Intents.h> //其中包含了#import <CoreSpotlight/CoreSpotlight.h>

• 由于shortcut是iOS12才出现的，所有的操作都应该符号系统要求

    if (@available(iOS 12.0, *)) {
        NSString *invocationPhrase = @"哈哈哈";
        [self isInvocationPhraseExist:invocationPhrase block:^(BOOL exist, INVoiceShortcut *voiceShortcut) {
            [self donateShortCutsWithInvocationPhrase:invocationPhrase exist:exist voiceShortcut:voiceShortcut];
        }];
    }

• 添加新的shortcut之前要先判断指令是否已经添加过

  查询操作是在子线程中执行的，拿到查询结果之后要返回主线程

/**
 判断捷径是否已经存在
 */
- (void)isInvocationPhraseExist:(NSString *)invocationPhrase block:(void (^)(BOOL exist, INVoiceShortcut *voiceShortcut))block API_AVAILABLE(ios(12.0)){
    NSLog(@"currentThread：%@", [NSThread currentThread]);//主线程
    //获取该app已经添加过的捷径，避免重复添加
    [[INVoiceShortcutCenter sharedCenter] getAllVoiceShortcutsWithCompletion:^(NSArray<INVoiceShortcut *> * _Nullable voiceShortcuts, NSError * _Nullable error) {
        if (!error) {
            dispatch_async(dispatch_get_main_queue(), ^{
                BOOL exist = NO;
                INVoiceShortcut *voiceShortcut = nil;
                for (INVoiceShortcut *shortcut in voiceShortcuts) {
                    if ([shortcut.invocationPhrase isEqualToString:invocationPhrase]) {
                        exist = YES;
                        voiceShortcut = shortcut;
                        break;
                    } else {
                        exist = NO;
                    }
                }
                block(exist, voiceShortcut);
            });
        }
    }];
}

• 创建或者修改shortcut

指令不存在则添加，存在则修改

/**
 创建或者修改语音捷径

 @param invocationPhrase 提示的语音输入语句
 @param exist 是否已经存在
 @param voiceShortcut 已经存在的语音语句
 */
- (void)donateShortCutsWithInvocationPhrase:(NSString *)invocationPhrase exist:(BOOL)exist voiceShortcut:(INVoiceShortcut *)voiceShortcut  API_AVAILABLE(ios(12.0)){
    NSUserActivity *activity = [[NSUserActivity alloc] initWithActivityType:@"com.cc.siri"];
    activity.eligibleForSearch = YES;
    activity.title = @"我是title";
    activity.eligibleForPrediction = YES;
    activity.suggestedInvocationPhrase = invocationPhrase;

    CSSearchableItemAttributeSet *set = [[CSSearchableItemAttributeSet alloc] init];
    set.thumbnailData = UIImagePNGRepresentation([UIImage imageNamed:@"icon"]);
    set.contentDescription = @"我是描述";

    activity.contentAttributeSet = set;

    INShortcut *shortCut = [[INShortcut alloc] initWithUserActivity:activity];
    if (!exist) { //添加
        INUIAddVoiceShortcutViewController *shortCutVc = [[INUIAddVoiceShortcutViewController alloc] initWithShortcut:shortCut];
        shortCutVc.delegate = self;
        [self presentViewController:shortCutVc animated:YES completion:nil];
    } else { //修改 此处需要用已经存在的voiceShortcut来初始化控制器
        INUIEditVoiceShortcutViewController *shortCutVc = [[INUIEditVoiceShortcutViewController alloc] initWithVoiceShortcut:voiceShortcut];
        shortCutVc.delegate = self;
        [self presentViewController:shortCutVc animated:YES completion:nil];
    }
}

• 事件处理

在appdelefate中监听，根据userActivity.activityType对不同的指令做相应的处理

- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray<id<UIUserActivityRestoring>> * _Nullable))restorationHandler
{
    if ([userActivity.activityType isEqualToString:@"com.cc.siri"]) {
        //代码块
    }
    return YES;
}

• 代理

添加和修改有不同的代理，都要分别实现

1. 添加 INUIAddVoiceShortcutViewControllerDelegate

两个方法：

/*!
 @abstract Called after the user finishes the setup flow for the voice shortcut, with either the successfully-added voice shortcut, or an error.
 @discussion Your implementation of this method should dismiss the view controller.
 */
- (void)addVoiceShortcutViewController:(INUIAddVoiceShortcutViewController *)controller didFinishWithVoiceShortcut:(nullable INVoiceShortcut *)voiceShortcut error:(nullable NSError *)error;

/*!
 @abstract Called if the user cancels the setup flow; the voice shortcut was not added.
 @discussion Your implementation of this method should dismiss the view controller.
 */
- (void)addVoiceShortcutViewControllerDidCancel:(INUIAddVoiceShortcutViewController *)controller;

2. 修改 INUIEditVoiceShortcutViewControllerDelegate

三个方法：

/*!
@abstract Called if the user updates the voice shortcut, with either the successfully-updated voice shortcut, or an error.
@discussion Your implementation of this method should dismiss the view controller.
*/
- (void)editVoiceShortcutViewController:(INUIEditVoiceShortcutViewController *)controller didUpdateVoiceShortcut:(nullable INVoiceShortcut *)voiceShortcut error:(nullable NSError *)error;

/*!
@abstract Called if the user deletes the voice shortcut.
@discussion Your implementation of this method should dismiss the view controller.
*/
- (void)editVoiceShortcutViewController:(INUIEditVoiceShortcutViewController *)controller didDeleteVoiceShortcutWithIdentifier:(NSUUID *)deletedVoiceShortcutIdentifier;

/*!
@abstract Called if the user cancelled; no changes were made to the voice shortcut.
@discussion Your implementation of this method should dismiss the view controller.
*/
- (void)editVoiceShortcutViewControllerDidCancel:(INUIEditVoiceShortcutViewController *)controller;

注意

• suggestedInvocationPhrase在分类里

NSUserActivity的.h中并没有属性suggestedInvocationPhrase，该属性其实是在分类NSUserActivity+IntentsAdditions里面，需要导入头文件

#import <Intents/NSUserActivity+IntentsAdditions.h>

Intents/Intents.h中包含了#import <CoreSpotlight/CoreSpotlight.h>

• 查询是否添加过指令时，下面代码新开了一个线程，拿到结果后需要返回主线程

[[INVoiceShortcutCenter sharedCenter] getAllVoiceShortcutsWithCompletion:^(NSArray<INVoiceShortcut *> * _Nullable voiceShortcuts, NSError * _Nullable error) {
  
}
