我听说iOS7在CBCentralManager中引入了此功能，但找不到方法.有可能吗还有另外一种使用GKPeerPickerController的widthout方法吗?

推荐答案

否，如果用户关闭了蓝牙，则您只能显示警报或消息，要求他们将其打开.

No, if the user has turned off Bluetooth all you can do is display an alert or message asking them to turn it on.

- (void)centralManagerDidUpdateState:(CBCentralManager *)central {

    if (central.state == CBCentralManagerStatePoweredOff) {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle: @"Error" message: @"Please turn on Bluetooth in Settings" delegate: nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
       [alert show]; 
    }
 }
