我想重新加载不使用tableview.reloadData()方法的TableView,因为我使用了MVVM结构,所以我将模型类附加到情节提要,问题是我的tableview首先被重新加载,然后我得到了所有数据我该如何解决这个问题,如果有人有解决方案,请帮助我!!
这是情节提要模型附件
型号代码:-
class MovieModel: Decodable{
var artistName: String = ""
var trackName: String = ""
init(artistName: String, trackName: String){
self.artistName = artistName
self.trackName = trackName
}
}
class ResultModel: Decodable{
var results = [MovieModel]()
init(results: [MovieModel]) {
self.results = results
}
}
我的ViewModel文件代码:-
class MovieViewModel: NSObject {
var artistName: String = ""
var trackName: String = ""
var movieModel: MovieModel?
var movieData = [MovieViewModel]()
override init() {
}
init(movie: MovieModel) {
self.artistName = movie.artistName
self.trackName = movie.trackName
}
func getData(){
Service.shareInstance.getAllMovieData { (movie, error) in
if error == nil{
self.movieData = movie?.map({return MovieViewModel(movie: $0)}) ?? []
print(self.movieData)
}else{
print("\(String(describing: error))")
}
}
}
func numberOfRow(section:Int) -> Int{
return movieData.count
}
func cellForRow(indexPath: IndexPath) -> MovieViewModel{
return self.movieData[indexPath.row]
}
}
我的ViewController代码:-
class ViewController: UIViewController {
@IBOutlet var movieVM: MovieViewModel?
@IBOutlet var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
self.movieVM?.getData()
}
}
extension ViewController: UITableViewDelegate, UITableViewDataSource{
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return movieVM?.numberOfRow(section: section) ?? 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell")
let movie = movieVM?.cellForRow(indexPath: indexPath)
cell?.textLabel?.text = movie?.artistName
cell?.detailTextLabel?.text = movie?.trackName
return cell!
}
}
就我而言,我不会重新加载tableview,所有这些操作都是使用ModelClass完成的!谢谢!
