Swift 高德地图 公交站点查询

2022-03-31

1、先初始化 AMapSearchAPI ，继承 AMapSearchDelegate 这个代理

    @IBOutlet weak var tableView: UITableView!
@IBOutlet weak var segment: UISegmentedControl!

var _startPoi = BMKPoiInfo()
var _endPoi = BMKPoiInfo()
///起点坐标
var route:AMapRoute?
var type:TransferType?
//高德地图
var searchGD : AMapSearchAPI!
var list = [AMapTransit]()

override func viewDidLoad() {
    super.viewDidLoad()
    
    self.title = "查询结果"
    // Do any additional setup after loading the view.
    tableView.register(UINib(nibName: "TransferListTableViewCell", bundle: nil), forCellReuseIdentifier: "TransferListCell")
    
    
    segment.addTarget(self, action: #selector(segmentedControlChange(_ :)), for: .valueChanged)
    
    searchGD = AMapSearchAPI.init()
    searchGD.delegate = self
    
    reloadData()
}

@objc func segmentedControlChange(_ segmented: UISegmentedControl) {
    if segmented.selectedSegmentIndex == 0 {
        print("第0个啊哈哈")
        searchRight(0)
    }
    else if segmented.selectedSegmentIndex == 1 {
        print("第1个啊哈哈")
        searchRight(2)
    }
    else {
        print("其他啊哈哈")
        searchRight(3)
    }
}


func reloadData()  {
    list.removeAll()
    list.append(contentsOf: route?.transits ?? [])
    self.tableView.reloadData()
}

2、 发起搜索 代理是路线查询的 数据

   extension TransferListViewController:AMapSearchDelegate{
        //MARK: - 高德地图 搜索线路规划
      func searchRight(_ tag:NSInteger) {
    
      //        驾车导航策略，默认策略为0。
    //           ///公交换乘策略([default = 0])\n 0-最快捷模式；\n 1-最经济模式；\n 2-最少换乘模式；\n 3-最少步行模式；\n 4-最舒适模式；\n 5-不乘地铁模式
    let request = AMapTransitRouteSearchRequest()
    request.origin = AMapGeoPoint.location(withLatitude: CGFloat(_startPoi.pt.latitude), longitude: CGFloat(_startPoi.pt.longitude))
    request.destination = AMapGeoPoint.location(withLatitude: CGFloat(_endPoi.pt.latitude), longitude: CGFloat(_endPoi.pt.longitude))
    request.strategy = tag
    request.requireExtension = true
    request.city = "龙口市"
    searchGD.aMapTransitRouteSearch(request)

}

func onRouteSearchDone(_ request: AMapRouteSearchBaseRequest!, response: AMapRouteSearchResponse!) {
    if response.count > 0 {
        //解析response获取路径信息
        self.route = response.route
        self.reloadData()
    }else{
        showToast("抱歉，未找到结果")
    }
}
}

extension TransferListViewController:UITableViewDelegate,UITableViewDataSource{
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return list.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let tran = list[indexPath.row]
    let time = Date.timeStampToString(timeStamp: tran.duration).replacingOccurrences(of: ":", with: "小时")
    let cell = tableView.dequeueReusableCell(withIdentifier: "TransferListCell") as! TransferListTableViewCell
    cell.titleLabel.text = tran.segments.first?.buslines.first!.name
    //tran.distance/1000
    cell.subLabel.text = "\(time)分钟 | \(String(format: "%.1f", CGFloat(tran.distance)/CGFloat(1000)) )公里 | \(String(format: "%.1f", CGFloat(tran.walkingDistance)/CGFloat(1000)))公里"
    return cell
}

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    return 0.1
}

func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
    return 0.1
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let tran = list[indexPath.row]
    let channel = TransferStepDetailsViewController(nibName: "TransferStepDetailsViewController", bundle: nil)
    channel.tran = tran
    channel._startPoi = _startPoi
    channel._endPoi = _endPoi
    self.navigationController?.pushViewController(channel, animated: true)
}

}
