ユーザーが検索すると、最初の表のビュー（searchHome）に結果が表示されます。
1つのセルを選択すると、次のtableView（bookDetail）にその詳細情報が表示されます。
bookDetailでは、instagramのように1つのセルしか存在しません（私のページでは多くの画像を見ることができますが、1つを選択します。どのようにinstagramのようにtableviewからtableviewにデータを渡すのですか？ swift
ただし、searchHomeのデータはdetailBookに渡されません。
この問題では3つのクラスがあります。
1つのデータを渡すためのクラス（BookAPIResult）
別あり、他方はdetailIndoためのUITableViewControllerのクラス（bookDetail）
class BookAPIresult {
// thumbnail url
var thumbnail : String?
// book title
var title : String?
// book author
var author : String?
// book pub.
var pubnm : String?
// book description
var description : String?
// sellerID
var seller : String?
// list Price
var listPrice : String?
// selling Price
var sellPrice : String?
// UIImage for Thumbnail
var thumbnailImage : UIImage?
}
とSearchHomeクラス下にある検索のためのUITableViewControllerのクラス（SearchHome）
あります。
class SearchHome: UITableViewController, UISearchBarDelegate, UISearchControllerDelegate{
// MARK: - Properties
let searchController = UISearchController(searchResultsController: nil)
// var barButton = UIBarButtonItem(title: "Search", style: .Plain, target: nil, action: nil)
let apiKey : String = "cbccaa3f2e893c245785c3b94d980b0c"
var searchString : String = ""
var list = Array<BookAPIresult>()
// MARK: - View Setup
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.delegate = self
self.tableView.dataSource = self

最後はdetailBookです。

override func viewDidLoad() {

self.navigationController?.hidesBarsOnTap = false

let backBtn = UIBarButtonItem(title: "뒤로가기", style: .Plain, target: self, action: "back:")
self.navigationItem.leftBarButtonItem = backBtn
//swipe to back
let backSwipe = UISwipeGestureRecognizer(target: self, action: "back:")
backSwipe.direction = UISwipeGestureRecognizerDirection.Right
self.view.addGestureRecognizer(backSwipe)
//dynamic cell height
tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 620
}
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 0
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
//define cell
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! detailBookCell
let row = self.bookDetail[indexPath.row]
cell.author.text = row.author
cell.pubnm.text = row.pubnm
cell.listPrice.text = row.listPrice
cell.sellPrice.text = row.sellPrice
cell.detailInfo.text = row.description
cell.detailInfo.sizeToFit()
let url = NSURL(string: row.thumbnail!)
let imageData = NSData(contentsOfURL: url!)
cell.bookImage.image = UIImage(data:imageData!)
return cell
}
//back button
func back(recognizer: UISwipeGestureRecognizer){
self.navigationController?.popViewControllerAnimated(true)
bookDetail.removeAll()
}
}
SearchHomeのpostInfo.bookDetail.append（bookInfo）の後、0値はdetailBookクラスのbookDetail（配列）にあります。 – kimpro
