【菜鸟初学Swift】IOS平台常用传感器的使用方式

一、加速度、陀螺仪、电源、距离传感器的使用方法：

import UIKitimport CoreMotion   //传感器的使用，引入库 CoreMotionimport CoreLocation  //磁场传感器的使用，引入库 CoreLocationclass ViewController: UIViewController,CLLocationManagerDelegate {    var cmm:CMMotionManager! //创建类：CMMotionManager    var lm:CLLocationManager!    override func viewDidLoad() {        super.viewDidLoad()        // Do any additional setup after loading the view, typically from a nib.        cmm = CMMotionManager()     //创建实例        lm = CLLocationManager()        lm.delegate = self    }    func StartAccerometer(){        //（一）、以下是获取加速度数据的使用方法        cmm.accelerometerUpdateInterval = 1    //获取频率，每1S获取一次        if cmm.accelerometerAvailable && !cmm.accelerometerActive{  //判断传感器是否为可用？且没活动            cmm.startAccelerometerUpdatesToQueue(NSOperationQueue(), withHandler: {(data:CMAccelerometerData?,err:NSError?) in                //传入加速度传感器数据                print("加速度数据：\(data)")    //打印加速度数据            })        }else{              print("加速度传感器不可用")             }    }    func StartGyrometer(){         //（二）、以下是获取陀螺仪数据的使用方法        cmm.gyroUpdateInterval = 1  //获取陀螺仪数据频率        if cmm.gyroAvailable && !cmm.gyroActive{   //判断传感器是否为可用？且没活动            cmm.startGyroUpdatesToQueue(NSOperationQueue(), withHandler: {                (data:CMGyroData?,err:NSError?) in                print("陀螺仪数据：\(data)")            })        }else{            print("陀螺仪传感器不可用")   }    }    func Startproximitymeter(){      //（三）、监听距离传感器状态的使用方法        UIDevice.currentDevice().proximityMonitoringEnabled = true  //启用距离传感器    NSNotificationCenter.defaultCenter().addObserver(self, selector:Selector("ProximityChanged"), name: UIDeviceProximityStateDidChangeNotification, object: nil)    }    func ProximityChanged(){        //  UIDevice.currentDevice().proximityState        //获取距离传感器状态，是否有障碍物，对应的结果：true 和 fault        print("\(UIDevice.currentDevice().proximityState)")    }    func StartListenBatteryLevel(){    //（四）、监听电量状态的方法    UIDevice.currentDevice().batteryMonitoringEnabled = true        NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector("BatteryLevel"), name: UIDeviceBatteryLevelDidChangeNotification, object: nil)    }    func BatteryLevel(){    UIDevice.currentDevice().batteryState        print("\(UIDevice.currentDevice().batteryLevel)")    }    func locationManager(manager: CLLocationManager, didUpdateHeading newHeading: CLHeading) {        print(newHeading)    }    func StopBatteryLevel(){    NSNotificationCenter.defaultCenter().removeObserver(self, name: UIDeviceBatteryLevelDidChangeNotification, object: nil) //移除    }    func StopProximity(){    NSNotificationCenter.defaultCenter().removeObserver(self, name: UIDeviceProximityStateDidChangeNotification, object: nil) //移除    }    func StopAcceler(){        if cmm.accelerometerActive{                        //如果加速器传感器还在活动            cmm.stopAccelerometerUpdates()                     //停止侦听加速器传感器        }    }    func StopGyro(){        if cmm.gyroActive {            cmm.stopGyroUpdates()        }    }    override func viewWillAppear(animated: Bool) {     //view呈现出来的时候启动        StartAccerometer()        StartGyrometer()        Startproximitymeter()        StartListenBatteryLevel()        lm.startUpdatingHeading()    }    override func viewWillDisappear(animated: Bool) {      //程序界面消失        StopAcceler()        StopGyro()        StopProximity()        StopBatteryLevel()    }    override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()        // Dispose of any resources that can be recreated.    }}

二、磁场传感器的使用

import UIKitimport CoreLocation   //磁场传感器的使用引入库：CoreLocationclass ViewController: UIViewController,CLLocationManagerDelegate {    var lm:CLLocationManager!    override func viewDidLoad() {        super.viewDidLoad()        // Do any additional setup after loading the view, typically from a nib.        lm = CLLocationManager()        lm.delegate = self        }    func locationManager(manager: CLLocationManager, didUpdateHeading newHeading: CLHeading) {        print(newHeading)    }    override func viewWillAppear(animated: Bool) {        lm.startUpdatingHeading()    }

不懂英文，学起来还是比较吃力的。又是英文基础良好的，学起来必定既轻松又好玩。
