我正在尝试开发一个应用程序,其中的数据是从JSON获取的。现在我参与了搜索,问题是搜索不起作用(显示所有数据)。请帮我。这是代码。
JSON数据的链接为:http://jsonplaceholder.typicode.com/photos
import UIKit
import Alamofire
import AlamofireImage
import SwiftyJSON
class ViewController: UIViewController ,UITableViewDelegate,UITableViewDataSource,UISearchBarDelegate {
@IBOutlet weak var searchbarValue: UISearchBar!
weak open var delegate: UISearchBarDelegate?
@IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.searchbarValue?.delegate = self
self.searchBarSearchButtonClicked(self.searchbarValue)
}
var albumArray = [AnyObject]()
var searchURL = String()
typealias JSONStandard = [String : AnyObject]
var url = ("https://jsonplaceholder.typicode.com/photos")
func callAlamo(url : String){
Alamofire.request(url).responseJSON(completionHandler: {
response in
self.parseData(JSONData: response.data!)
})
}
func parseData(JSONData : Data) {
do {
Alamofire.request("https://jsonplaceholder.typicode.com/photos").responseJSON { (responseData) -> Void in
if((responseData.result.value) != nil) {
let swiftyJsonVar = JSON(responseData.result.value!)
//
if let resData = swiftyJsonVar[].arrayObject {
self.albumArray = resData as [AnyObject]; ()
}
if self.albumArray.count > 0 {
self.tableView.reloadData()
}
}
}
}
catch{
print(error)
}
}
func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
let keywords = searchbarValue.text
let finalKeywords = keywords?.replacingOccurrences(of: " ", with: "+")
searchURL = "https://jsonplaceholder.typicode.com/photos?q=\(finalKeywords!)"
//print(searchURL)
callAlamo(url: searchURL)
self.view.endEditing(true)
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return albumArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as? CostumTableViewCell
let title = albumArray[indexPath.row]
cell?.titleLabel?.text = title["title"] as? String
let imageUrl = title["thumbnailUrl"] as? String
//print(imageUrl)
let urlRequest = URLRequest(url: URL(string: imageUrl!)!)
Alamofire.request(urlRequest).responseImage { response in
if let image = response.result.value {
// print("image downloaded: \(title["url"])")
cell?.url?.image = image
}
}
return cell!
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
performSegue(withIdentifier: "showDetails", sender: self)
}
// override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
// let indexPath = self.tableView.indexPathForSelectedRow?.row
//
// let vc = segue.destination as! DetailsViewController
//
// }
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
let indexPath = self.tableView.indexPathForSelectedRow
let cell : CostumTableViewCell = self.tableView.cellForRow(at: indexPath!) as! CostumTableViewCell
let vc = segue.destination as! DetailsViewController
vc.image2 = cell.url.image!
vc.title2 = cell.titleLabel.text!
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
