Question

我已将我的代码从swift 2.3更新为swift 3＆amp;得到了很多错误，所有错误都被删除了

我在didSelectRowAt indexPath上遇到错误：UITableView的索引路径

任务：我点击API获取数据并在tableview中填充数据，但是我想在didselectrowatindexpath上保存数据这一切都在swift2.3中为我工作

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

    print("selected ")
    //print(self.searchflightsandfares[indexPath.row] as SearchFlightsAndFares)

    let data: NSData
   // data = NSKeyedArchiver.archivedData(withRootObject: self.searchflightsandfares[indexPath.row].airlineCodeOneWay)

    data = NSKeyedArchiver.archivedData(withRootObject: self.searchflightsandfares[indexPath.row]) as SearchFlightsAndFares


    //Set Data
    UserDefaults.standard.set(data, forKey: "selectedFlightDetailData")

    SelectedFlightDetailsVC()
}

错误是

模型类是：

    import UIKit
import Foundation

class SearchFlightsAndFares:NSObject{

    //segment data
    var segmentaDataForDetailScreen:[NSDictionary]
    var fareDataFromFlight:Dictionary<String, AnyObject>

    //Flight Details -One Way
    var airlineCodeOneWay:      String? //for list view
    var airlineNameOneWay:      String? //for list view
    var airlineCodeOneWaySegment:String? //for Detail view
    var airlineNameOneWaySegment:String? //for Detail view

init(fareDataFromFlight:            Dictionary<String, AnyObject>,
         segmentaDataForDetailScreen:   [NSDictionary],
         airlineCodeOneWay:             String, //for list view
         airlineNameOneWay:             String, //for list view
         airlineCodeOneWaySegment:      String, //Flight Number one way

aaaah最后我得到了它在swift 3.0中这个函数func encodeWithCoder(aCoder: NSCoder) {}改为func encode(with aCoder: NSCoder)得到了Solution for this感谢您的时间和帮助@vadian

Answer 2

如果您的searchflightsandfares数组类型是

let searchflightsandfares = [SearchFlightsAndFares]()

然后你需要写这个

data = NSKeyedArchiver.archivedData(withRootObject: searchflightsandfares[indexPath.row]) as NSData

希望它能帮到你

从swift 2.3迁移到swift 3时出现问题
