有没有一个API，通过它我可以告诉大家，如果苹果的设备（新iPad / iPod / iPhone的），我的应用程序运行在支持蓝牙低功耗（BTLE）。

Is there an API via which I can tell if the Apple device (iPad/iPod/iPhone) that my App is running on supports Bluetooth Low Energy (BTLE).

推荐答案

假设你有一个的iOS5或iOS6的设备和你有一个CBCentralManager对象，你可以用下面的检查其CBCentralManagerState：

Assuming you have an iOS5 or iOS6 device and that you have a CBCentralManager object, you can check its CBCentralManagerState with the following:

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.";

}

您会想观看 centralManagerDidUpdateState：中央委托更新为好，然后采取适当的行动，您的应用程序

You'll want to watch for centralManagerDidUpdateState:central delegate updates as well, then take the appropriate action in your app.
