Startanzeige bei Suche in der Suchleiste

Question

Ich muss eine Suchleiste erstellen, um das Produkt zu suchen. Dafür benutze ich SearchController und ich habe eine API für die Suche nach Produkten nach Namen. Ich will das: animierende Anzeige bei der Suche aus API verarbeitet. Wie kann ich das lösen? Dies ist mein Code von api für die Suche:

func getTovar(){ 

    Alamofire.request(.GET, "myApiurl") 
     .responseJSON { response in 
      guard response.result.error == nil else { 
       // got an error in getting the data, need to handle it 
       print("error calling GET on /todos/1") 
       print(response.result.error!) 
       self.indicator.stopAnimating() 
       UIApplication.sharedApplication().networkActivityIndicatorVisible = false 

       return 
      } 

      if let value = response.result.value { 
       // handle the results as JSON, without a bunch of nested if loops 
       let product = JSON(value) 
       for (_,subJson):(String, JSON) in product { 

        let img:NSData 
        if let src=subJson["sphoto"].string{ 

         if src.containsString("jpg"){ 
          let range = src.startIndex.advancedBy(2)..<src.endIndex 
          let substring = src[range] 
          var urlString = "http://admin.unimax.kz/\(substring)" 
          urlString = urlString.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())! 
          if let dataFromURL=NSData(contentsOfURL: NSURL(string: urlString)!){ 
           img=dataFromURL 
          } 
          else{ 
           img=NSData(contentsOfURL: NSURL(string: "http://zhaksy-adam.kz/Images/domalak.png")!)! 
          } 
         } 
         else{ 
          img=NSData(contentsOfURL: NSURL(string: "http://zhaksy-adam.kz/Images/domalak.png")!)! 
         } 
        } 
        else{ 
         img=NSData(contentsOfURL: NSURL(string: "http://zhaksy-adam.kz/Images/domalak.png")!)! 
        } 

        //Do something you want 
        let id=subJson["id"].int! 
        let name=subJson["name"].string! 
        let price=subJson["price"].int! 
        let description=subJson["description"].rawString() 
        self.data.append(Product(id:id,title: name, img: UIImage(data: img), price: price,desc:description!)) 
       } 
      } 
    } 
} 

Diese meine Suchergebnisse Aktualisierung ist:

func updateSearchResultsForSearchController(searchController: UISearchController) 
{ 
    searchController.searchBar.addSubview(indicator) 
    indicator.stopAnimating() 

    getTovar() 

    for item in data { 
     if item.productTitle.containsString(searchController.searchBar.text!){ 
      filteredTableData.append(item) 
     } 

    } 

    indicator.stopAnimating() 
    self.tableView.reloadData() 
}

Sie müssen Sie den Code ändern, wie dies Ihr getTover wie diese

ändern

func getTovar(){ 

    Alamofire.request(.GET, "myApiurl") 
     .responseJSON { response in 
      guard response.result.error == nil else { 
       // got an error in getting the data, need to handle it 
       print("error calling GET on /todos/1") 
       print(response.result.error!) 
       self.indicator.stopAnimating() 
       UIApplication.sharedApplication().networkActivityIndicatorVisible = false 
       indicator.stopAnimationg() 
       return 
      } 

      if let value = response.result.value { 
       // handle the results as JSON, without a bunch of nested if loops 
       let product = JSON(value) 
       for (_,subJson):(String, JSON) in product { 

        let img:NSData 
        if let src=subJson["sphoto"].string{ 

         if src.containsString("jpg"){ 
          let range = src.startIndex.advancedBy(2)..<src.endIndex 
          let substring = src[range] 
          var urlString = "http://admin.unimax.kz/\(substring)" 
          urlString = urlString.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())! 
          if let dataFromURL=NSData(contentsOfURL: NSURL(string: urlString)!){ 
           img=dataFromURL 
          } 
          else{ 
           img=NSData(contentsOfURL: NSURL(string: "http://zhaksy-adam.kz/Images/domalak.png")!)! 
          } 
         } 
         else{ 
          img=NSData(contentsOfURL: NSURL(string: "http://zhaksy-adam.kz/Images/domalak.png")!)! 
         } 
        } 
        else{ 
         img=NSData(contentsOfURL: NSURL(string: "http://zhaksy-adam.kz/Images/domalak.png")!)! 
        } 

        //Do something you want 
        let id=subJson["id"].int! 
        let name=subJson["name"].string! 
        let price=subJson["price"].int! 
        let description=subJson["description"].rawString() 
        self.data.append(Product(id:id,title: name, img: UIImage(data: img), price: price,desc:description!)) 
       } 
       indicator.stopAnimationg() 
       for item in data { 
        if item.productTitle.containsString(searchController.searchBar.text!){ 
         filteredTableData.append(item) 
        } 
       } 
       self.tableView.reloadData() 
      } 
    } 
} 

Und ändern Sie Ihre updateSearchResultsForSearchController wie diese

func updateSearchResultsForSearchController(searchController: UISearchController){ 
    searchController.searchBar.addSubview(indicator) 
    indicator.startAnimating() 
     getTovar() 
} 

Hoffe, das wird helfen.
