问题，同时迅速从2.3迁移到SWIFT 3

Question

我已经更新了我的代码从SWIFT 2.3至3迅速得到&许多错误移除所有的人，但来到这里卡住

我得到错误的didSelectRowAt indexPath：中IndexPath UITableView的

任务：我打了数据API和实现代码如下其工作正常填充数据，但我想保存这一切是在swift2.3为我工作在didSelectRowAtIndexPath方法数据

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() 
} 

误差

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

{ 


     self.fareDataFromFlight    = fareDataFromFlight 
     self.segmentaDataForDetailScreen = segmentaDataForDetailScreen 
     //One Way 
     self.airlineCodeOneWay    = airlineCodeOneWay 
     self.airlineNameOneWay    = airlineNameOneWay 
     self.airlineCodeOneWaySegment  = airlineCodeOneWaySegment 
} 

init(espDictionary: [String : AnyObject]) 
    { 

    logic for assignment from API to InIt Variables //….more code … 
} 

required init(coder aDecoder: NSCoder) { 
     self.fareDataFromFlight     = (aDecoder.decodeObject(forKey: "fareDataFromFlight") as? Dictionary<String, AnyObject>)! 
     self.segmentaDataForDetailScreen   = (aDecoder.decodeObject(forKey: "segmentaDataForDetailScreen") as? [NSDictionary])! 
     //One Way 
     self.airlineCodeOneWay   = aDecoder.decodeObject(forKey: "airlineCodeOneWay") as? String 
     self.airlineNameOneWay   = aDecoder.decodeObject(forKey: "airlineNameOneWay") as? String 
     self.airlineCodeOneWaySegment = aDecoder.decodeObject(forKey: "airlineCodeOneWaySegment") as? String 
     self.airlineNameOneWaySegment = aDecoder.decodeObject(forKey: "airlineNameOneWaySegment") as? String

} 


func encodeWithCoder(aCoder: NSCoder) { 


     aCoder.encode(self.fareDataFromFlight,     forKey: "fareDataFromFlight") 
     aCoder.encode(self.segmentaDataForDetailScreen,   forKey: "segmentaDataForDetailScreen") 

     //One way 
     aCoder.encode(self.airlineCodeOneWay,   forKey: "airlineCodeOneWay") 
     aCoder.encode(self.airlineNameOneWay,   forKey: "airlineNameOneWay")

Answer 1

AAAAH最后我得到了它在SWIFT 3.0这个功能func encodeWithCoder(aCoder: NSCoder) {}改为​​在Solution for this感谢您的时间得到了refrence和帮助阵列self.searchflightsandfares的@vadian

Answer 2

如果您searchflightsandfares数组类型是

let searchflightsandfares = [SearchFlightsAndFares]() 

，那么你需要写这个

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

希望它会帮助你

Answer 3

不需要额外的声明行。这不是Objective-C。评论一下。

// let data: Data 

数组中的项目应该是铸造而不是归档对象。所以把右括号放到最后。

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

如果您的数据源阵列申报的具体雨燕（[SearchFlightsAndFares]）你不需要投什么。
