最近公司接了個(gè)項(xiàng)目，是一款運(yùn)動(dòng)類(lèi)型的APP，可以檢測(cè)運(yùn)動(dòng)量（例如：步數(shù)，上下樓等）、睡眠信息、速度等信息，因?yàn)橐郧按致缘牧私膺^(guò)傳感器方面的相關(guān)信息，知道主要是蘋(píng)果設(shè)備內(nèi)置的傳感器在起作用，傳感器的種類(lèi)也很多，有興趣的可以去查看蘋(píng)果官方文檔或者查閱大神們的博客都可以找到！但是一直也沒(méi)有自己寫(xiě)一下，做個(gè)測(cè)試：

話(huà)不多說(shuō)，代碼如下：

1、準(zhǔn)備

//  計(jì)步器  var myTextView = UITextView()  var pedometer = CMPedometer()  var myBtn = UIButton()

2、在plist文件中添加相關(guān)權(quán)限描述：

Privacy - Motion Usage Description ：String 計(jì)步器需要獲取您的運(yùn)動(dòng)信息

3、具體代碼如下：

  myBtn.frame = CGRect(x:10,y:360,width:kScreenWidth-20,height:50)  myBtn.setTitle("按鈕", for: .normal)  myBtn.setTitle("倒計(jì)時(shí)中", for: .disabled)  myBtn.backgroundColor = UIColor.orange  myBtn.setTitleColor(UIColor.white, for: .normal)  myBtn.setTitleColor(UIColor.blue, for: .disabled)  myBtn.addTarget(self, action: #selector(btnClick), for: .touchUpInside)  self.view.addSubview(myBtn）func btnClick(){  self.startPedometerUpdates()      }//  ---------------------------------計(jì)步器--------------------------------------------func creatPedometer(){  myTextView.frame = CGRect(x:20,y:100,width:kScreenWidth-20,height:200)  self.view.addSubview(myTextView)  //    創(chuàng)建觸發(fā)按鈕  myBtn.frame = CGRect(x:10,y:360,width:kScreenWidth-20,height:50)  myBtn.setTitle("按鈕", for: .normal)//    myBtn.setTitle("倒計(jì)時(shí)中", for: .disabled)  myBtn.backgroundColor = UIColor.orange//    myBtn.setTitleColor(UIColor.white, for: .normal)//    myBtn.setTitleColor(UIColor.blue, for: .disabled)  myBtn.addTarget(self, action: #selector(btnClick), for: .touchUpInside)  self.view.addSubview(myBtn)}//  開(kāi)始獲取步數(shù)統(tǒng)計(jì)數(shù)據(jù)func startPedometerUpdates(){  //   判斷設(shè)備支持情況  guard CMPedometer.isStepCountingAvailable() else {    self.myTextView.text = "/n當(dāng)前設(shè)備不支持獲取步數(shù)/n"    return  }  //    獲取今天凌晨時(shí)間  let cal = Calendar.current  var comps = cal.dateComponents([.year,.month,.day], from: Date())  comps.hour = 0  comps.minute = 0  comps.second = 0  let midnightOfToday = cal.date(from: comps)  //初始化并開(kāi)始實(shí)時(shí)獲取數(shù)據(jù)    self.pedometer.startUpdates (from: midnightOfToday!, withHandler: { pedometerData, error in      //錯(cuò)誤處理      guard error == nil else {        print(error!)        return      }          //獲取各個(gè)數(shù)據(jù)      var text = "---今日運(yùn)動(dòng)數(shù)據(jù)---/n"      if let numberOfSteps = pedometerData?.numberOfSteps {        text += "步數(shù): /(numberOfSteps)/n"      }      if let distance = pedometerData?.distance {        text += "距離: /(distance)/n"      }      if let floorsAscended = pedometerData?.floorsAscended {        text += "上樓: /(floorsAscended)/n"      }      if let floorsDescended = pedometerData?.floorsDescended {        text += "下樓: /(floorsDescended)/n"      }      if #available(iOS 9.0, *) {        if let currentPace = pedometerData?.currentPace {          text += "速度: /(currentPace)m/s/n"        }      } else {        // Fallback on earlier versions      }      if #available(iOS 9.0, *) {        if let currentCadence = pedometerData?.currentCadence {          text += "速度: /(currentCadence)步/秒/n"        }      } else {        // Fallback on earlier versions      }      //        在線(xiàn)程中更新文本框數(shù)據(jù)      DispatchQueue.main.async {                self.myTextView.text = text      }        })

然后，測(cè)試了下，親自去爬了3層樓梯，如下圖：
