Tür 'BusinessData' üyesinin 'sortUsingComparator' üyesi yok

Question

Bir url'den veri alıyorum ve tablo görünümünde göstermeye çalışıyorum. Bundan önce ben doğrudan tüm dizi, arama, sıralama.Its iyi çalıştı.Ama şimdi, benim tablo görünümü için ayrı bir sınıf oluştururken, bu hata alıyorum benim sırala işlevimde

Type 'BusinessData' has no member 'sortUsingComparator' alıyorum. Bu düğme kodu içinde bu sıralama kodunu bildiriyorum. Ama şimdi bu hatayı alıyorum.

benim bussinessData.swift sınıf

import UIKit 

class BusinessData { 

    var BusinessName: String? 
    var Address: String? 
    var Rating: Float? 
    var ContactNumber: String? 

    init(json: NSDictionary) { 
     self.BusinessName = json["business_name"] as? String 
     self.Address = json["location"] as? String 
     self.Rating = json["__v"] as? Float 
     self.ContactNumber = json["phone_no"] as? String 


    } 


} 

Benim viewcontroller.swift kodu: ben bu alıyorum her yöntemde

@IBAction func sortByAZBtnPress(sender: AnyObject) 
    { 
     RightMenu.hidden = true 



     BusinessData.sortUsingComparator { (dict1, dict2) -> NSComparisonResult in 

      if let name1 = dict1["business_name"] as? String, name2 = dict2["business_name"] as? String 
      { 
       return name1.compare(name2) 
      } 

      return .OrderedAscending 
     } 
     self.tableView.reloadData() 
    } 

    @IBAction func sortByRatingBtnPress(sender: AnyObject) 
    { 

     RightMenu.hidden = true 

     BusinessData.sortUsingComparator { (dict1, dict2) -> NSComparisonResult in 

      if let name1 = dict1["rating"] as? String, name2 = dict2["rating"] as? String 
      { 
       return name2.compare(name1) 
      } 

      return .OrderedDescending 
     } 
     self.tableView.reloadData() 


    }

     BusinessData.sortUsingComparator { (dict1, dict2) -> NSComparisonResult in

Bunda bu düğme eylem yöntemi hatası alıyorum hata Type 'BusinessData' has no member 'sortUsingComparator' .. Bu satırda:

BusinessData.sortUsingComparator { (dict1, dict2) -> NSComparisonResult in

Answer 1

BusinessData bir modeli sınıftır

Teşekkür bana yardım edin. Yapmak istediğiniz şey, var arrDict = [BusinessData]() - BusinessData örneklerinin bir dizisini sıralamaktır.

Geçerli kodunuz BusinessData.sortUsingComparator { (dict1, dict2) -> NSComparisonResult in, model sınıfında bir sınıf yöntemini çağırmaya çalışıyor ve 2 sözlük geri gelmeyi bekliyor.

arrDict.sortUsingComparator { (b1, b2) -> NSComparisonResult in 

nerede b1 ve b2BusinessData örnekleri değil, sözlükleri şunlardır:

Ne istiyorsun gibi daha fazla bir şeydir.
