在 2 个部分中分离 Realm Bool 数据 Tableview

Question

美好的一天！我有一个小问题。我想通过 Bool 值（true 和 false）从 Realm DB 中分离数据。如果 Bool 数据 currencyStatusCode == true 则在第一个 tableview 部分 "Active accounts" 显示货币名称、currencyCode 和余额，如果 Bool 数据 currencyStatusCode == false 则在第二部分 "Inactive accounts"。以及我添加数据库外观的图像。非常感谢您的帮助。

var sections = ["Active accounts", "Inactive accounts"]

@IBOutlet weak var accountManagerTableView: UITableView!


let realm = try? Realm()
let accounts = try! Realm().objects(currencyAccounts.self).sorted(byKeyPath: "currencyID")
var accountManager: currencyAccounts?
var accountsRecord: Results<currencyAccounts> {
    get {
        return realm!.objects(currencyAccounts.self)
    }
}
override func numberOfSections(in tableView: UITableView) -> Int {
    return sections.count
}

override func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    return sections[section]
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    return accounts.count

 /*   switch (section) {
    case 0:


            return accounts.count
     break;


    case 1:



            return accounts.count
            break;

    default:
        break;

    }

return section
   */


    }

   override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {


    let cell = accountManagerTableView.dequeueReusableCell(withIdentifier: "activeCurrencyCell", for: indexPath) as! accountManagerTableViewCell

    let sortingtInTableView = realm?.objects(currencyAccounts.self).sorted(byKeyPath: "currencyID", ascending: true)
    let currentUserBalances = sortingtInTableView![indexPath.row]


            cell.currencyFullName.text = currentUserBalances.currencyName
            cell.currencyTitle.text = currentUserBalances.currencyCode
            cell.selectedAccountBalance.text = String(currentUserBalances.currencyBalance)


    return cell

}

Realm DB data

您再次使用过滤器 Realm 对象本身。详情请参考 documentation。请找到过滤活动和非活动帐户的代码：

let realm = try! Realm()

let activeAccounts = realm.objects(Dog.self).filter("currencyStatusCode = true").sorted(byKeyPath: "currencyID")


// Persist your data easily
try! realm.write {
    realm.add(activeAccounts)
}


let realm = try! Realm()

let inactiveAccounts = realm.objects(Dog.self).filter("currencyStatusCode = false").sorted(byKeyPath: "currencyID")


// Persist your data easily
try! realm.write {
    realm.add(inactiveAccounts)
}
