ios – 如何检测我的苹果设备是否支持Bluetooth Low Energy

有没有API可以告诉我的应用程序运行的Apple设备(iPad / iPod / iPhone)是否支持蓝牙低功耗(BTLE).

解决方法

假设您有一个iOS5或iOS6设备,并且您有一个CBCentralManager对象,您可以使用以下内容检查其CBCentralManagerState：

switch ([_manager state])
{
    case CBCentralManagerStateUnsupported:
        state = @"This device does not support Bluetooth Low Energy.";
        break;
    case CBCentralManagerStateUnauthorized:
        state = @"This app is not authorized to use Bluetooth Low Energy.";
        break;
    case CBCentralManagerStatePoweredOff:
        state = @"Bluetooth on this device is currently powered off.";
        break;
    case CBCentralManagerStateResetting:
        state = @"The BLE Manager is resetting; a state update is pending.";
        break;
    case CBCentralManagerStatePoweredOn:
        state = @"Bluetooth LE is turned on and ready for communication.";
        break;
    case CBCentralManagerStateUnknown:
        state = @"The state of the BLE Manager is unknown.";
        break;
    default:
        state = @"The state of the BLE Manager is unknown.";

}

您将需要观看centralManagerDidUpdateState：中央委托更新,然后在您的应用程序中采取适当的操作.
