iOS | iPhone唤醒iWatch 以及 iWatch唤醒iPhone

最近有些忙，watchApp做完了暂时告一段落了，但知识还是要整理，还是要记下的。
做watchApp，总会有需要唤醒iPhoneApp，再进一步做些操作的时候，代码不多，几句话搞定，在此做简单整理。

一、iPhone唤醒iWatch

iPhone端配置configuration信息，healthStore调用startWatchApp方法，iWatch端调用handle方法可取出configuration信息，即实现了iPhone唤醒iWatch。

1、Objective-C

//iPhone App
- (void)wakeUpWatchApp {
    //配置一些configuration信息
    HKWorkoutConfiguration *configuration = [[HKWorkoutConfiguration alloc]init];
    configuration.locationType = HKWorkoutSessionLocationTypeOutdoor;
    configuration.activityType = HKWorkoutActivityTypeRunning;
    //检查是否安装对应的watchApp
    if ([WCSession defaultSession].isWatchAppInstalled && [WCSession defaultSession].isPaired) {
        //调用startWatchApp即可
        [self.healthStore startWatchAppWithWorkoutConfiguration:configuration completion:^(BOOL success, NSError * _Nullable error) {
            if (error) {
            } else {
                // 唤醒成功
            }
        }];
    }
}

//watch app
//handle方法 可接收到host app端所配置的 configuration
-  (void)handleWorkoutConfiguration:(HKWorkoutConfiguration *)workoutConfiguration {
     //do something
     //可直接取出configuration信息 workoutConfiguration.activityType
}

2、Swift

// iPhone App
func wakeUpWatchApp () {
    //配置一些configuration信息
    var workoutConfiguration = HKWorkoutConfiguration()
    workoutConfiguration.locationType = .outdoor        
    workoutConfiguration.activityType = .running
    //检查是否安装对应的watchApp
    if WCSession.default().isPaired && WCSession.default().isWatchAppInstalled {
        //调用startWatchApp即可
        healthStore.startWatchApp(with: workoutConfiguration) { (success, error) in
             // ...
    }   
}

//watch app
//handle方法 可接收到host app端所配置的 configuration
func handle(_ workoutConfiguration: HKWorkoutConfiguration) {
     //do something
     //可直接取出configuration信息 workoutConfiguration.activityType
}

二、iWatch唤醒iPhone

利用WCSession向iPhone app发送消息，则唤醒iPhone。
需要注意的一点是，watch唤醒iPhoneApp并不能将app拉起至前端，但在后台已经启动了，所以没有看到app起来不要以为他没唤醒哦~

小方法：可让iPhone app启动后 发出一些声音，这样你就可以知道已经唤醒app啦。

1、Objective-C

// iPhone app
// appDelegate.m  
// 当watch app 使用sendMessage发送消息时 iPhone app会调用此方法 做回应处理
- (void)session:(nonnull WCSession *)session didReceiveMessage:(nonnull NSDictionary *)message replyHandler:(nonnull void (^)(NSDictionary * __nonnull))replyHandler {
    // 接收到watch app 发送的message
    NSLog(@"Message: %@", message);
    // 返回发送 消息已到达 信息至 watch app
    replyHandler(@"Text was received.");
}

//watch app
- (void) wakeUpMyApp {
    //需检查app是否可达，才能使消息发送成功
    if ([WCSession defaultSession].isReachable) {
        //发送message : wakeUp
        [[WCSession defaultSession].sendMessage: "wakeUp" replyHandler: ^(NSDictionary * __nonnull replyMessage) {
             // do something
             NSLog(@"reply info : %@",replyMessage);
        } errorHandler:^(NSError * __nonnull error) {
            //do something
             NSLog(@"Error = %@",error);
        }];
    }
}

2、Swift

//watch app
func wakeUpMyAPP () {
     //需检查app是否可达，才能使消息发送成功
     if WCSession.default().isReachable {
         //发送message : wakeUp
         WCSession.default().sendMessage(["message": "wakeUp"], replyHandler: {(message: [String : Any]) -> Void in
             //do something
             print("reply info : \(message)")               
         }, errorHandler: {(Error) -> Void in
             //do something
             print("Error : \(Error)")
         })
     }
}

//iPhone app
func session(session: WCSession, didReceiveMessage message: [String : AnyObject], replyHandler: ([String : AnyObject]) -> Void) {
     // 接收到watch app 发送的message
     print("message : \(message)")    
     // 返回发送 消息已到达 信息至 watch app
     replyHandler("Text was received.")
}
