ios - 使用未解析的标识符 '_ComboItemId'

Question

你好 friend ，我在创建模型类时遇到奇怪的错误虽然我已经创建了该类，但它显示错误
任何建议!!
谢谢您

这是代码

import Foundation
class ComboModel {
private var _ComboItemId: String!
private var _ComboMainCategory: String!
private var _ComboCategoryId: String!
}

var ComboItemId : String {
return _ComboItemId // Error Use of unresolved identifier '_ComboItemId'
}

init(ComboItemId : String) {
 self._ComboItemId = ComboItemId // Error Initializers may only be declared within a type
}

Answer 1

这是一个简单的用户错误。你有一个带有私有(private)变量的类

class ComboModel {
    private var _ComboItemId: String!
    private var _ComboMainCategory: String!
    private var _ComboCategoryId: String!
} // your class ends here!!!

现在您正在尝试访问 ComboModel 类私有(private)变量 _ComboItemId。

var ComboItemId : String {
    return _ComboItemId // Error Use of unresolved identifier '_ComboItemId'
}

所以，这可能就是您正在寻找的:

class ComboModel {
    private var _ComboItemId: String!
    private var _ComboMainCategory: String!
    private var _ComboCategoryId: String!

    var ComboItemId : String {
        return _ComboItemId
    }

    init(ComboItemId : String) {
        self._ComboItemId = ComboItemId
    }

}
