ios - 如何在 iOS 中的 uitableViewCell 上显示当前位置

Question

我想在 TableViewCell 上显示当前位置地址。我得到了纬度和经度，但我不明白如何在单元格上显示地址字符串。

我在ViewDidLoad()中编写了以下代码它在标签中显示地址。

let manager: CLLocationManager = locationManager
  CLGeocoder().reverseGeocodeLocation(manager.location!, completionHandler: {(placemarks, error)->Void in

let placemark = placemarks?[0]

let lines = placemark?.addressDictionary?["FormattedAddressLines"]

let addressString = (lines as! NSArray).componentsJoined(by: "\n")

self.lblAddress.text = addressString

print(addressString)

})


but i want to show the address on tableview Cell.

 //return cell for perticular row withing section

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
    if indexPath.section <= 1
    {

        let cell = tableView.dequeueReusableCell(withIdentifier: "CellRID", for: indexPath)

        cell.textLabel?.text = "\(self.batteryLevel() * 100) %"

        return cell
     }

     else

     {

          //create reusable cell object by dequeueReusableCellWithIdentifier

          //identifier must register with cell

         let cell = tableView.dequeueReusableCell(withIdentifier: "LocationTableViewCellRID", for: indexPath) as! LocationTableViewCell

         let personName = txtFieldName.text

         let a = LocationVC()

         cell.lblName?.text = "\(personName) \(self.batteryLevel() * 100) %"

         cell.lblAddress?.text = 

         return cell
     }
}

我想在 lblAddress 上显示地址。我是 iOS 新手。预先感谢您的帮助。

Answer 1

您应该在 viewDidLoad 方法上方声明 addressString 的属性。不在 viewDidLoad 方法内。

将其添加到 viewDidLoad 方法上方

let addressString = String()

然后在viewDidLoad方法中更改这一行

let addressString = (lines as! NSArray).componentsJoined(by: "\n")

至

self.addressString = (lines as! NSArray).componentsJoined(by: "\n")
