创建Intent Definition File
方法:File → New → File
新建Intent
创建完后如下界面:
可以看到Intent是一个Category,我们可以设置类型(标示Intent的作用),添加参数(根据Siri解析命令传入),添加标题,描述(这些会显示在Siri唤醒我们app的时候)。
编译的时候系统会自动生成一个子类XXXIntent : INIntent,我们需要找到这个类,使用这个类来进行我们的其他操作。
点击如下图位置:
开发过程
权限获取
获取当前权限
INSiriAuthorizationStatus siriStatus = [INPreferences siriAuthorizationStatus]; 复制代码
请求获取权限
[INPreferences requestSiriAuthorization:^(INSiriAuthorizationStatus status) { switch (status) { case INSiriAuthorizationStatusAuthorized: // 成功获取权限 NSLog(@"权限获取成功"); break; case INSiriAuthorizationStatusDenied: // 成功获取权限 NSLog(@"权限获取用户拒绝"); break; default: break; } }]; 复制代码
注意添加info.plist(或者多语言)设置提示语,否则权限请求不会弹出。
添加Siri快捷指令页面
调用系统API,调用如下页面。
代码如下:
GotoPageIntent *intent = [[GotoPageIntent alloc] init]; // GotoPageIntent为我们自定义的Intent,找不到看上面 intent.suggestedInvocationPhrase = @"打开app"; // 这是建议的提示语,会展示在页面上 INShortcut *shortcurt = [[INShortcut alloc] initWithIntent:intent]; INUIAddVoiceShortcutViewController *addvc = [[INUIAddVoiceShortcutViewController alloc] initWithShortcut:shortcurt]; addvc.delegate = self; [self presentViewController:addvc animated:YES completion:nil]; 复制代码
处理回调:
/*! @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; { if (!error) { [controller dismissViewControllerAnimated:YES completion:nil]; } } /*! @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; { [controller dismissViewControllerAnimated:YES completion:nil]; } 复制代码
处理Siri Shortcuts触发的回调
- 自定义xxxIntentHandler,继承自NSObject。遵循xxxIntentHandling(这个是我们Xcode自己生成的,找的方法见上面创建Intent Definition File中),在里面实现我们需要的逻辑。
- (void)handleGotoPage:(GotoPageIntent *)intent completion:(void (^)(GotoPageIntentResponse *response))completion NS_SWIFT_NAME(handle(intent:completion:)) { // GotoPageIntentResponseCodeContinueInApp 打开app // GotoPageIntentResponseCodeSuccess 回调成功 GotoPageIntentResponse *response = [[GotoPageIntentResponse alloc] initWithCode:GotoPageIntentResponseCodeSuccess userActivity:nil]; completion(response); } 复制代码
- 打开我们的Extension,IntentHander方法。处理我们自己定义的Intent。
- (id)handlerForIntent:(INIntent *)intent { if ([intent isKindOfClass:[GotoPageIntent class]]) { return [[GotoAppIntentHandler alloc] init]; } return self; } 复制代码
