大佬教程收集整理的这篇文章主要介绍了外围没有连接 – 斯威夫特,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
didFailToConnectPeripheral或didConnectPeripheral都没有返回任何值.
我如何让它工作?
import UIKit import CoreBluetooth class ViewController: UIViewController,CBCentralManagerDelegate,CBPeripheralDelegate { var manager: CBCentralManager! override func viewDidLoad() { super.viewDidLoad() manager = CBCentralManager (delegate: self,queue: nil) } func centralManager(central: CBCentralManager,didDiscoverPeripheral peripheral: CBPeripheral,advertisementData: [String : AnyObject],RSSI: NSnumber) { print("Peripheral: \(peripheral)") manager.connectPeripheral(peripheral,options:nil) manager.stopScan() } func centralManager(central: CBCentralManager,didConnectPeripheral peripheral: CBPeripheral) { print("connected!") } func centralManager(central: CBCentralManager,didDisconnectPeripheral peripheral: CBPeripheral,error: NSError?) { print("disconnected!") } func centralManager(central: CBCentralManager,didFailToConnectPeripheral peripheral: CBPeripheral,error: NSError?) { print("Failed") } func centralManagerDidupdateState(central: CBCentralManager) { print("checking") switch(central.statE) { case.Unsupported: print("BLE is not supported") case.Unauthorized: print("BLE is unauthorized") case.UnkNown: print("BLE is UnkNown") case.ResetTing: print("BLE is ResetTing") case.PoweredOff: print("BLE service is powered off") case.PoweredOn: print("BLE service is powered on") print("Start ScAnning") manager.scanForPeripheralsWithservices(nil,options: nil) default: print("default state") } } }
import UIKit import CoreBluetooth class ViewController: UIViewController,CBPeripheralDelegate { var manager: CBCentralManager! var connecTingPeripheral: CBPeripheral? override func viewDidLoad() { super.viewDidLoad() manager = CBCentralManager (delegate: self,RSSI: NSnumber) { print("Peripheral: \(peripheral)") self.connecTingPeripheral=peripheral manager.connectPeripheral(peripheral,options:nil) manager.stopScan() } ... }
