iOS12 SiriKit新特性 shortcuts（一）（Objective-C版本）

iOS12 的SiriKit添加了新特性shortcuts，相當於玩電腦時使用者佈建快速鍵一個道理，比如我設定ctrl+f10為開啟記事本，設定成功後，我每次直接按ctrl+f10都可以快速開啟記事本。

shortcuts這次有兩種用法，第一種為設定快捷語（shortcut，下同）後，通過Siri直接回到應用，在回到應用時可以擷取設定快捷語時所攜帶資料，可依據該資料或不依據該資料自動進行下一步操作。

第二種用法為設定擴充頁面，不進入app以完成應用的簡單操作功能，如：發資訊/下單等。

今天先簡單介紹一下第二種用法，先看一下效果，如：

 建立個SIngle View APP，命名：GotoSiri，語言為：Objective-C

再在File->New->Target->Intents Extension ,記得勾選include UI Extension，後期需要顯示擴充頁面。命名：Ticket，建立完成後需點擊兩次Activate。

工程目錄中出現如下兩個檔案夾：

接下來需要建立intents.intentdefinition檔案，看名字像自訂意圖，其實很雞肋。

New File->SiriKit Intent Definition File

 

新添加一個名為Test的Intent，建立好後運行一次程式，再點擊Test，在標註區會看到剛才設定好的意圖檔案名稱TestIntent，點擊右側箭頭會進入TestIntent.h標頭檔中，後期用這個自訂的TestIntent意圖時需要引入的標頭檔。

 

在ViewController.m檔案中，引入“TestIntent.h”和<Intents/Intents.h>兩個標頭檔。

#import "ViewController.h"#import "TestIntent.h"#import <Intents/Intents.h>@interface ViewController ()<TestIntentHandling, INUIAddVoiceShortcutViewControllerDelegate>@property(nonatomic,strong) INUIAddVoiceShortcutViewController *customShortCutViewController;@property(nonatomic,strong) TestIntent *testIntent;@property(nonatomic,strong) TestIntentResponse *testIntentResponse;@property(nonatomic,strong) INInteraction *interaction;@property(nonatomic,strong) INShortcut *shortcut;@end@implementation ViewController- (void)viewDidLoad {    [super viewDidLoad];    // Do any additional setup after loading the view, typically from a nib.        self.title = @"SiriTest";    if (@available(iOS 10.0, *)) {                [INPreferences requestSiriAuthorization:^(INSiriAuthorizationStatus status) {            switch (status) {                case INSiriAuthorizationStatusNotDetermined:                    NSLog(@"使用者尚未對該應用程式作出選擇。");                    break;                case INSiriAuthorizationStatusRestricted:                    NSLog(@"此應用程式無權使用Siri服務");                    break;                case INSiriAuthorizationStatusDenied:                    NSLog(@"使用者已明確拒絕此應用程式的授權");                    break;                case INSiriAuthorizationStatusAuthorized:                    NSLog(@"使用者可以使用此應用程式的授權");                    break;                default:                    break;            }                    }];    }        UIButton *_addSiriBtn = [[UIButton alloc] initWithFrame:CGRectMake(30, 151, 200, 50)];    [_addSiriBtn setTitle:@"Add to Siri(Intent)" forState:UIControlStateNormal];    [_addSiriBtn setTitleColor:UIColor.blueColor forState:UIControlStateNormal];    [_addSiriBtn addTarget:self action:@selector(buildShortcutInCurrentViewController) forControlEvents:UIControlEventTouchUpInside];        [self.view addSubview:_addSiriBtn];}-(void)buildShortcutInCurrentViewController{    self.testIntent = [[TestIntent alloc] init];    self.testIntent.ticket = @"深圳灣體育館王力宏演唱會";    self.testIntent.number = [NSNumber numberWithInteger:2];    self.testIntent.suggestedInvocationPhrase = @"買票";        self.interaction = [[INInteraction alloc] initWithIntent:self.testIntent response:nil];    [self.interaction donateInteractionWithCompletion:^(NSError * _Nullable error) {        if(error)        {            NSLog(@"%@",error);        }        else        {            NSLog(@"donate success");        }    }];        INShortcut *shortCut = [[INShortcut alloc] initWithIntent:self.testIntent];    self.customShortCutViewController = [[INUIAddVoiceShortcutViewController alloc] initWithShortcut:shortCut];    self.customShortCutViewController.delegate = self;    [self presentViewController:self.customShortCutViewController animated:YES completion:nil];}-(void)addVoiceShortcutViewControllerDidCancel:(INUIAddVoiceShortcutViewController *)controller{    [controller dismissViewControllerAnimated:YES completion:nil];}-(void)addVoiceShortcutViewController:(INUIAddVoiceShortcutViewController *)controller didFinishWithVoiceShortcut:(INVoiceShortcut *)voiceShortcut error:(NSError *)error{    [controller dismissViewControllerAnimated:YES completion:nil];}- (void)handleTest:(nonnull TestIntent *)intent completion:(nonnull void (^)(TestIntentResponse * _Nonnull))completion {    NSString *ticket = intent.ticket;    self.testIntentResponse = [TestIntentResponse successIntentResponseWithTicket:ticket];    completion(self.testIntentResponse);}-(void)confirmTest:(nonnull TestIntent *)intent completion:(nonnull void (^)(TestIntentResponse * _Nonnull))completion{    NSString *ticket = intent.ticket;    self.testIntentResponse = [TestIntentResponse successIntentResponseWithTicket:ticket];    completion(self.testIntentResponse);}@end

千萬別忘記修改三個Info.plist檔案

GotoSiri中的info.plist，

 

 

Ticket中的info.plist，

 

 

 TicketUI中的info.plist，

在IntentHandler.m檔案中：

#import "IntentHandler.h"#import "TestIntent.h"@interface IntentHandler ()<TestIntentHandling>@end@implementation IntentHandler- (id)handlerForIntent:(INIntent *)intent {    // This is the default implementation.  If you want different objects to handle different intents,    // you can override this and return the handler you want for that particular intent.    return self;}- (void)handleTest:(TestIntent *)intent completion:(void (^)(TestIntentResponse * _Nonnull))completion {    if(intent.number == 0)    {        completion([TestIntentResponse failureIntentResponseWithTicket:intent.ticket]);    }    completion([TestIntentResponse successIntentResponseWithTicket:intent.ticket]);}-(void)confirmTest:(TestIntent *)intent completion:(void (^)(TestIntentResponse * _Nonnull))completion{    completion([[TestIntentResponse alloc] initWithCode:TestIntentResponseCodeReady userActivity:nil]);}@end

在TicketUI的MainInterface.storyboard中畫個簡單介面

 

IntentViewController.m中：

#import "IntentViewController.h"#import <Intents/Intents.h>#import "TestIntent.h"// As an example, this extension‘s Info.plist has been configured to handle interactions for INSendMessageIntent.// You will want to replace this or add other intents as appropriate.// The intents whose interactions you wish to handle must be declared in the extension‘s Info.plist.// You can test this example integration by saying things to Siri like:// "Send a message using <myApp>"@interface IntentViewController ()@property (weak, nonatomic) IBOutlet UILabel *testlabel;@end@implementation IntentViewController- (void)viewDidLoad {    [super viewDidLoad];    // Do any additional setup after loading the view.}#pragma mark - INUIHostedViewControlling// Prepare your view controller for the interaction to handle.- (void)configureViewForParameters:(NSSet <INParameter *> *)parameters ofInteraction:(INInteraction *)interaction interactiveBehavior:(INUIInteractiveBehavior)interactiveBehavior context:(INUIHostedViewContext)context completion:(void (^)(BOOL success, NSSet <INParameter *> *configuredParameters, CGSize desiredSize))completion {    // Do configuration here, including preparing views and calculating a desired size for presentation.        TestIntent *intent = (TestIntent *)interaction.intent;    self.testlabel.text = [NSString stringWithFormat:@"購買%@張%@門票",intent.number,intent.ticket];        if (completion) {        completion(YES, parameters, [self desiredSize]);    }        if(interaction.intentHandlingStatus == INIntentHandlingStatusSuccess)    {        self.testlabel.text = @"###123###";    }}- (CGSize)desiredSize {    CGSize customSize = [self extensionContext].hostedViewMaximumAllowedSize;    customSize.height = 200.0;    return customSize;}@end
