问题描述
我对Xcode中的蓝牙有问题。对于如何检查蓝牙是否开启,我找不到很好的解决方案。我只想要那个。我在网上搜索了一些解决方案,但对我没有任何帮助。关于如何检查蓝牙的任何想法?我导入了CoreBluetooth类,并编写了以下代码行:
I have a problem with the Bluetooth in Xcode. I can’t find a great solution on how to check if Bluetooth is on or not. I want just that. I searched around the web some solution, but nothing works for me. Any idea on how to check Bluetooth? I imported the CoreBluetooth class and I made this line of code:
if CBPeripheralManager.authorizationStatus() == .denied { code }
if CBPeripheralManager.authorizationStatus() == .authorized { code }
推荐答案
实现 CBCentralManagerDelegate
委托。
var manager:CBCentralManager!
viewDidLoad() { // Or init()
manager = CBCentralManager()
manager.delegate = self
}
委托方法:
func centralManagerDidUpdateState(_ central: CBCentralManager) {
switch central.state {
case .poweredOn:
break
case .poweredOff:
print("Bluetooth is Off.")
break
case .resetting:
break
case .unauthorized:
break
case .unsupported:
break
case .unknown:
break
default:
break
}
}
