ios - 无法使用 iBecon Signal 的服务 ID 通过 CBCentral Manager 进行扫描
<p><p>使用核心蓝牙处理 iBecon 信号,我可以使用 CBCentralManager 扫描选项 nil 进行搜索:-</p>
<pre><code>Shared.sharedInstance.centralManager?.scanForPeripherals(withServices: nil, options:)
</code></pre>
<p>但是当我提供我想要的服务 ID 时,即:-</p>
<pre><code>Shared.sharedInstance.centralManager?.scanForPeripherals(withServices: , options:)
</code></pre>
<p>它从不调用 didDiscoverPeripheral Delegate 方法,我也需要在后台模式下扫描外围设备,根据苹果文档,您需要在需要在后台模式下扫描时明确提供服务 ID。任何人都可以帮助我在这里做错了什么。</p></p>

<p><p>我是这样使用的,
连接按钮点击事件
并使用 <code>CBCentralManagerDelegate, CBPeripheralDelegate</code> 委托(delegate)</p>
<pre><code>func connectDevice(sender:UIButton){
if peripheral != nil {
manager.cancelPeripheralConnection(peripheral)
manager = CBCentralManager(delegate: self, queue: nil)
}
}
func centralManagerDidUpdateState(central: CBCentralManager) {
if central.state == CBCentralManagerState.PoweredOn {
central.scanForPeripheralsWithServices(nil, options: nil)
} else {
self.showAlert(Messages().alert , message: "Bluetooth is not on.")
}
}
func centralManager(central: CBCentralManager, didDiscoverPeripheral peripheral: CBPeripheral, advertisementData: , RSSI: NSNumber) {
let device = (advertisementData as NSDictionary).objectForKey(CBAdvertisementDataLocalNameKey) as? NSString
print(device)
if device?.containsString(BEAN_NAME) == true {
self.manager.stopScan()
self.peripheral = peripheral
self.peripheral.delegate = self
manager.connectPeripheral(peripheral, options: nil)
}
}
</code></pre></p>
