蓝牙设置

Question

尝试动态设置蓝牙对话。管理以追查我无法弄清楚的问题。在peripheralManagerDidUpdateState内;设置服务。现在这个代码有效！

func peripheralManagerDidUpdateState(peripheral: CBPeripheralManager) {
    if (peripheral.state != .PoweredOn) {
        return;
    }

    if (peripheral.state == .PoweredOn) {
        transferCharacteristic = CBMutableCharacteristic(type: cbtransfer, properties: .Notify, value: nil, permissions: .Readable)
        transferEvak = CBMutableCharacteristic(type: cbevak, properties: .Notify, value: nil, permissions: .Readable)
        transferPlay = CBMutableCharacteristic(type: characteristicsArray[3], properties: .Notify, value: nil, permissions: .Readable)
        transferService = CBMutableService(type: cbservice, primary: true)
        transferService.characteristics = [transferCharacteristic, transferEvak,transferPlay]
 peripheralManager!.addService(transferService)
        peripheralManager!.startAdvertising([CBAdvertisementDataServiceUUIDsKey :[cbservice]])

注意characteristicArray是使用我动态创建的UUID定义和填充的。

var characteristicsArray = [CBUUID]() 

确定;但我真的不想在transferService.characteristics中逐个添加特性;我想做这样的事情。

transferService.characteristics = CBMutableServicesCharacteristicsArray

但这不起作用，似乎我必须将transferService.characteristics定义为值的静态数组？我错过了什么？为什么呢？
