符合CBCentralManagerDelegate协议

Question

我正在尝试实施BLEHandler。

这是我的代码：

import CoreBluetooth

class BLEHandler : NSObject, CBCentralManagerDelegate {

    override init() {
        super.init()

    }

    func cenrealManagerDidUpdateState(central: CBCentralManager!)
    {
        switch (central.state)
        {
        case . unsupported:
            print("BLE is unsupported")
        case.unauthorized:
            print("BLE is unauthorised")
        case.unknown:
            print("BLE is unknown")
        case.resetting:
            print("BLE is resetting")
        case.poweredOff:
            print("BLE is powered off")
        case.poweredOn:
            print("BLE is powered on")
        default:
            print("BLE default")
        }
    }
}

我收到错误： “类型'BLEHandler'不符合协议'CBCentralManagerDelegate'”

我有'centralManagerDidUpdateState'方法，所以我不知道我错过了什么等。

方法名称拼写错误。不是cenrealManagerDidUpdateState，应该是centralManagerDidUpdateState

试试......

func centralManagerDidUpdateState(_ central: CBCentralManager)
{

}
