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.
