过去尝试解决这一问题已有十多天了，但仍然没有运气来解决这种情况。

我正在尝试根据“ ExerciseName”列的名称，按字母顺序从A-Z向表视图添加节。我也有一个“ BodyPartName”，“ CategoryName”？每个“ ExerciseName”的数据列。

我想填充A-Z中的部分，并在同一部分中将ExerciseName排序为BodyPartName和CategoryName，以用于同一行中的其他标签。

我成功地在A-Z部分实现了ExerciseName，但是无法将BodyPartName和CategoryName添加到同一行的其他标签中。请帮忙！

预期结果

A

Abs“（核心）”

手臂按“（武器）”“（哑铃）”

B

二头肌卷曲“（手臂）”“（杠铃）”

后退扩展名“（后退）”“（机器）”

无法为同一行填充“ BodyPartName”标签和“ CategoryName”标签。

这是我的领域数据模型：

class Exercises: Object
{

    @objc dynamic var ExerciseID = 0
    @objc dynamic var ExerciseName = ""
    @objc dynamic var BodyPartName = ""
    @objc dynamic var CategoryName: String? = ""

    //Adding Parent Table BodyPart & Category.
    var parentBodyParts = LinkingObjects(fromType: BodyParts.self,property: "exercises")
    var parentCategory = LinkingObjects(fromType: Category.self,property: "category")

}

我的代码：

let realm = try! Realm()
var exerciseArray: Results<Exercises>!

override func viewDidLoad()
    {
        super.viewDidLoad()
        tableView.register(UINib(nibName: "customCell",bundle: nil),forCellReuseIdentifier: cellID)
        sectionFunction()
    }

var sectionDictionary = [String:[String]]()
var sectionTitles = [String]()

func sectionFunction()
{
     exerciseArray = realm.objects(Exercises.self).sorted(byKeyPath: "ExerciseName")

    for section in exerciseArray
    {
        let sectionKey = String(section.ExerciseName.prefix(1)) 

        if var sectionValues = sectionDictionary[sectionKey]
        {
            sectionValues.append(section.ExerciseName) // Adding ExerciseNames to the Keys
            sectionDictionary[sectionKey] = sectionValues
        }
        else
        {
            sectionDictionary[sectionKey] = [section.ExerciseName]
        }
    }
    sectionTitles = [String](sectionDictionary.keys)
    sectionTitles = sectionTitles.sorted(by: {$0 < $1}) // Alphabetical order for Keys:Values
}

override func numberOfSections(in tableView: UITableView) -> Int
    {
        return sectionTitles.count
    }


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


    override func sectionIndexTitles(for tableView: UITableView) -> [String]?
    {
        return sectionTitles
    }


    override func tableView(_ tableView: UITableView,numberOfRowsInSection section: Int) -> Int
    {
        let sectionKey = sectionTitles[section]
        if let sectionValues = sectionDictionary[sectionKey]
        {
            return sectionValues.count
        }
        return 0
       // return exercises.filter("ExerciseName == %@",sectionNames[section]).count
    }

    // Register custom cell for Table View
    let cellID = "customCell"

    override func tableView(_ tableView: UITableView,cellForRowAt indexPath: IndexPath) -> UITableViewCell
    {
      let cell = tableView.dequeueReusableCell(withIdentifier: cellID,for: indexPath) as! customCell

        let sectionKey = sectionTitles[indexPath.section]
        if let sectionValues = sectionDictionary[sectionKey]
        {
          exerciseArray = realm.objects(Exercises.self).sorted(byKeyPath: "ExerciseName")

            cell.exerciseName.text = sectionValues[indexPath.row]
            cell.bodyPartName.text = exerciseArray.filter("ExerciseName == %@",sectionValues[indexPath.row]) [indexPath.row].BodyPartName
            cell.categoryName.text = exerciseArray.filter("ExerciseName == %@",sectionValues[indexPath.row])  [indexPath.row].CategoryName ?? ""
            cell.backgroundColor = .clear
        }
        return cell
    }

自定义单元格：

class customCell: UITableViewCell {

    @IBOutlet weak var exerciseName: UILabel!
    @IBOutlet weak var bodyPartName: UILabel!
    @IBOutlet weak var categoryName: UILabel!

    override func awakeFromNib() {
        super.awakeFromNib()
    }

override func setSelected(_ selected: Bool,animated: Bool) {
    super.setSelected(selected,animated: animated)   
}   

}
