Ios/swift/TableView/API画像連動

事前準備

以下を事前に見ておく

ios/swift/TableView/画像付き [ｼｮｰﾄｶｯﾄ]

ios/swift/外部ライブラリ/Alamofire [ｼｮｰﾄｶｯﾄ]

サンプル

画像とテキストのデータ配列を読み込めるAPIを叩いて、その情報をそのままTableViewで表示する

-ViewController.swift

import UIKit
import Alamofire
class ViewController: UIViewController ,UITableViewDataSource, UITableViewDelegate {
   @IBOutlet weak var imgTableView: UITableView!
   private var _imgs: Array<ImgInit> = []
   override func viewDidLoad() {
       super.viewDidLoad()
       imgTableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "Cell")
       imgTableView.delegate = self
       imgTableView.dataSource = self
   }
   func execapi() {
       Alamofire.request(.GET, "http://localhost/api/testimgs", parameters: ["param1": "value1"]).responseJSON { response in
           if response.result.isSuccess {
               let jsonDic = response.result.value as! NSDictionary
               let imgs = jsonDic["imgs"] as! NSArray
               let cnt = jsonDic["cnt"] as! Int
               print(cnt)
               for img in imgs {
                   let name:String = img["name"] as! String
                   let thumbnail:String = img["thumbnail"] as! String
                   let _img = ImgInit(name: name, thumbnail: thumbnail) as ImgInit
                   self._imgs.append(_img)
               }
               self.imgTableView.reloadData() // 更新
           }
       }
   }
   override func didReceiveMemoryWarning() {
       super.didReceiveMemoryWarning()
   }
   func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
       return self._imgs.count
   }
   func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
       print(self._imgs[indexPath.row].thumbnail)
       let cell =
           tableView.dequeueReusableCellWithIdentifier("CustomCell") as! CustomTableViewCell
       cell.setCell(self._imgs[indexPath.row].thumbnail, text: self._imgs[indexPath.row].name)
       return cell
   }
}

-CustomTableViewCell.swift

import UIKit
import SDWebImage
class CustomTableViewCell: UITableViewCell {
   @IBOutlet weak var customLabelView: UILabel!
   @IBOutlet weak var customImageView: UIImageView!
   func setCell(imgpath: String, text: String) {
       customLabelView.numberOfLines = 0; // 複数行
       if imgpath.containsString("http://") || imgpath.containsString("https://") {
           let imageURL = NSURL(string: imgpath)
           customImageView.sd_setImageWithURL(imageURL)
       } else {
           customImageView.image = UIImage(named:imgpath)
       }
       customLabelView.text = text
   }
}

-ImgInit.swift

class ImgInit {
   var name:String = ""
   var thumbnail:String = ""
   init(name: String, thumbnail: String) {
       self.name = name
       self.thumbnail = thumbnail
   }
}
