XBPrint

实现了蓝牙扫描，蓝牙连接，蓝牙断开等一些功能.
实现了基于esc-pos协议指令的蓝牙打印机的大部分命令.
实现了二维码的打印.

Requirements

iOS8+
Xcode7.2

Example Code

1.BluetoothManagerCode: 

 var bluetoothManager = XBBluetoothManager() //初始化
 bluetoothManager.delegate = self  //设置代理 
 bluetoothManager.startScan() //搜索附近的蓝牙设备  
 bluetoothManager.connectPeripheral(peripheral) //连接蓝牙设备 
 
 
2. ESC-POS Instruction: 

 //初始化打印机
 var printerInitialize: NSData! {
  get { 
      let cmmData = NSMutableData.init() 
      cmmData.appendByte(27) 
      cmmData.appendByte(64) 
      return cmmData   } 
 } 


 3. 发送打印指令: 
 let cfEnc = CFStringEncodings.GB_18030_2000 
 let enc = CFStringConvertEncodingToNSStringEncoding(CFStringEncoding(cfEnc.rawValue)) 
            
  //打印商家名称 
  let cmmStoreNameData = NSMutableData.init() 
  cmmStoreNameData.appendData(printerInitialize) 
  cmmStoreNameData.appendData(printerModel(0)) 
  cmmStoreNameData.appendData(printerCharacterSize(1)) 
  cmmStoreNameData.appendData(printerAlignment(1)) 
  let storeNameData = printTemplate.storeName.dataUsingEncoding(enc) 
  cmmStoreNameData.appendData(storeNameData!) 
  cmmStoreNameData.appendData(printerPaperFeed(2)) 
  bluetoothManager.writeValue(peripheral, data: cmmStoreNameData)
