Ios OBD2Kit Swift示例可以'；t打字，继续得到零

因为没有使用OBD2Kit和Swift的示例代码，所以我将其分叉并用作pod

我翻译了一些OBJ-C示例代码，但似乎无法将FLWiFiScanTool降级为ELM327类型。为什么我总是得零分

import UIKit
import OBD2Kit

class ViewController: UIViewController, FLScanToolDelegate {

    @IBOutlet weak var hostIpAddress: UITextField!

    var scanTool: ELM327!

    @IBOutlet weak var statusLabel: UILabel!
    @IBOutlet weak var scanToolLabel: UILabel!
    @IBOutlet weak var rpmLabel: UILabel!
    @IBOutlet weak var speedLabel: UILabel!
    @IBOutlet weak var tempLabel: UILabel!
    var scanning = false

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        self.hostIpAddress.text = "192.168.0.10"
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func scanButton(sender: UIButton) {
        if !scanning {
            startScan()
        } else {
            stopScan()
        }
    }

    func startScan() {
        if let scanTool = ELM327(host: self.hostIpAddress.text!, andPort: 35000) {
            self.statusLabel.text = "Initializing..."
            scanTool.useLocation = true
            scanTool.delegate = self
            scanTool.startScanWithSensors({() -> [AnyObject] in
                dispatch_async(dispatch_get_main_queue(), {() -> Void in
                    self.statusLabel.text = "Scanning..."
                    self.scanToolLabel.text = scanTool.scanToolName
                })

//                let sensors: [AnyObject] = [    OBD2Sensor.SensorEngineRPM as! AnyObject,

                let sensors: [AnyObject] = [    0x0C,
                                                0x0D,
                                                0x13    ]
                return sensors
            })
            self.scanTool = scanTool
            print("So far succesfull")
            scanning = !scanning
        } else {
            self.statusLabel.text = "Not working"
        }
    }

    func stopScan() {
        statusLabel.text = "Stopped"
        let scanTool: ELM327 = self.scanTool
        scanTool.cancelScan()
        scanTool.sensorScanTargets = nil
        scanTool.delegate = nil
        scanning = !scanning
    }

    // MARK: - FLScanToolDelegate


    func scanTool(scanTool: FLScanTool, sensor: FLECUSensor) {
        var sensorLabel: UILabel? = nil
        switch sensor.pid {

        case OBD2Sensor.SensorEngineRPM:
            sensorLabel = self.rpmLabel

        case OBD2Sensor.SensorVehicleSpeed:
            sensorLabel = self.speedLabel

        default:
            sensorLabel = self.tempLabel
        }

        self.showSensorValue(sensor, onLabel: sensorLabel!)
    }

    func showSensorValue(sensor: FLECUSensor, onLabel label: UILabel) {
        let sensorValue: String = "\(sensor.valueStringForMeasurement1(false)) \(sensor.imperialUnitString)"
        dispatch_async(dispatch_get_main_queue(), {() -> Void in
            label.text = sensorValue
        })
    }

}

我现在已经可以扫描工具了，因为ELM327是FLWiFiScanTool，而不是相反。我可以得到工具名，这样它就可以连接了，但似乎无法得到传感器的输出。

我设法找到了答案。预期的传感器阵列应该是NSNUMBER中的一个，因此我将传感器单元铸造为NSNUMBER。 我还错过了scanTool函数中的didUpdateSensor部分

一定要使用公制，在我的情况下，这更可靠。（我的车也使用公制，也许这就是原因。）

scanToolWithHost

能否失败？什么是

FLWifiScanTool

返回？请从您的问题中删除所有“已解决”部分，并将您的解决方案作为答案发布。谢谢。你可以先问然后回答你自己的问题，只是在问题部分不要两个都做。我已经将你的问题回滚到上一个“未解决”版本，因为有一个误解。我的意思是，你应该使用“你的答案”框发布你的解决方案。一个问题应该是一个问题；答案在问答部分，而不是问题中。谢谢
