#IBOutlet weak var tableView: UITableView!
var wisataArr = [String]()
var titleArr = [String]()
var imgUrlArr = [String]()
override func viewDidLoad() {
super.viewDidLoad()
self.downloadJsonWithURL()
}
func downloadJsonWithURL () {
let url = NSURL(string: urlString)
URLSession.shared.dataTask(with: (url as? URL)!, completionHandler: { (data, response, error) -> Void in
if let jsonObj = try? JSONSerialization.jsonObject(with: data!, options: .allowFragments) as? NSDictionary {
print(jsonObj!.value(forKey: "data"))
if let dataArray = jsonObj!.value(forKey: "data") as? NSArray {
for data in dataArray{
if let dataDict = data as? NSDictionary{
if let title = dataDict.value(forKey: "title"){
self.titleArr.append(title as! String)
}
if let title = dataDict.value(forKey: "category"){
self.wisataArr.append(title as! String)
}
if let title = dataDict.value(forKey: "image_satu"){
self.imgUrlArr.append(title as! String)
}
}
}
}
OperationQueue.main.addOperation({
self.tableView.reloadData()
})
}
}).resume()
}
func downloadJsonWitTask () {
let url = NSURL(string: urlString)
var downloadTask = URLRequest(url: (url as? URL)!, cachePolicy: URLRequest.CachePolicy.reloadIgnoringCacheData, timeoutInterval: 20)
downloadTask.httpMethod = "GET"
URLSession.shared.dataTask(with: downloadTask, completionHandler: { (data, response, error) -> Void in
let jsonObj = try? JSONSerialization.jsonObject(with: data!, options: .allowFragments)
print(jsonObj)
}).resume()
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return titleArr.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell") as! TableViewCell
cell.lblTitle.text! = titleArr[indexPath.row]
cell.lblWisata.text! = wisataArr[indexPath.row]
let imgUrl = NSURL(string: imgUrlArr[indexPath.row])
if imgUrl != nil {
let data = NSData(contentsOf: imgUrl as! URL)
cell.imgView.image = UIImage(data: data as! Data)
}
return cell
}
