获取UITableViewCell中嵌入的UITable单元格的indexPath

时间:2016-10-25 11:24:12

标签: ios swift uitableview

所以这是TableView的结构: 有一个主要的 UITableView ,在每个 UITableViewCell 里面还有另一个 UITableview

截图: TableView Screenshot

每个 UITableViewCells 都被设计为自定义视图,并通过在 cellForRowAtIndexPath 函数中从Nib加载来添加。

我想要做的是在内部表视图中选择的任何选项我想获取嵌入表视图的单元格的索引路径。

文件布局: Document Layout

我尝试按照 Paulw11 中提到的委托方法进行操作: swift: how to get the indexpath.row when a button in a cell is tapped?: StackOverflow

  

注意: Paulw11 建议的方法效果很好

码(TableVC):

class TableVC: UITableViewController, QuestionCellDelegate {

override func viewDidLoad() {
    super.viewDidLoad()

    // Uncomment the following line to preserve selection between presentations
    // self.clearsSelectionOnViewWillAppear = false

    // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
    // self.navigationItem.rightBarButtonItem = self.editButtonItem()
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

// MARK: - Table view data source
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    // #warning Incomplete implementation, return the number of rows
    return 5
}

override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {

    return 220.0
}


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

    let cell = Bundle.main.loadNibNamed("QuestionCell", owner: self, options: nil)?.first as! QuestionCell

    cell.delegate = self

    return cell
}

func sendCellInfo(cell: UITableViewCell) {

    print(cell)

    let indexPathForQuestion = tableView.indexPath(for: cell)

    print(indexPathForQuestion)
}}

码(QuestionCell):

protocol QuestionCellDelegate: class {

func sendCellInfo(cell: UITableViewCell)
}


class QuestionCell: UITableViewCell, UITableViewDelegate,      UITableViewDataSource{

@IBOutlet weak var optionsTableview: UITableView!

var delegate: QuestionCellDelegate?

override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code

    self.optionsTableview.delegate = self
    self.optionsTableview.dataSource = self
}

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

    // Configure the view for the selected state
}

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

    let cell = Bundle.main.loadNibNamed("OptionsCell", owner: self, options: nil)?.first as! OptionsCell

    return cell
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    return 4
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

    let selectedCell = optionsTableview.cellForRow(at: indexPath)

    print("selectedCell")

        self.delegate?.sendCellInfo(cell: selectedCell!)
}}

码(OptionsCell):

class OptionsCell: UITableViewCell {

override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code
}

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

    // Configure the view for the selected state
}}
  

注意:当前的O / P为 nil

     

注意:代码按照 pbasdf 的评论进行了更改,实现了错误

3 个答案:

答案 0 :(得分:1)

由于 pbasdf 评论找到了解决方案:

TableVC中的委托功能:

 func sendCellInfo(cell: UITableViewCell) {

    /*** Take the cell passed and convert to a CGPoint wrt to TableView ***/
    let cellPosition: CGPoint = cell.convert(cell.bounds.origin, to: self.tableView)

     /*** wrt to CGPoint find index on current TableView ***/
    /*** Returns as Section,Cell ***/
    let indexPathForSelectedCell = (tableView.indexPathForRow(at: cellPosition)?.row)

    print(indexPathForSelectedCell)
}

答案 1 :(得分:0)

使用此:

tableView.cellForRowAtIndexPath(YourIndexPath)为! OptionCell

您可以将自己的indexPath作为全局变量并在didSelectRow方法

上归档

YourIndexPath = indexPath

答案 2 :(得分:0)

以下答案是@Supratik Majumdar对我所说的逻辑的要求。

Supratik尝试使用以下代码,我希望您能满足您的需求。

//Initialize your question or answer in viewDidLoad or where ever you like to as shown below
self.questionArray = ["Question1", "Question2"]
self.optionArray = [["Option 1", "Option 2", "Option 3", "Option 4"], ["Option 1", "Option 2", "Option 3", "Option 4"]]


//Make us of the following tableview delegate & datasource code
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return self.questionArray.count
    }

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return self.OptionArray[section].count
}

func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String {
    return self.questionArray[section]
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! UITableViewCell

    let currentOptionArray = self.questionArray[section]
    let currentOption = currentOptionArray[indexPath.row]

    cell.textLabel.text = currentOption

    return cell
}

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    let selectedIndex = indexPath
    let selectedQuestionIndex = indexPath.section
    let selectedOptionIndex = indexPath.row

    //Make use of the data you need in the above values
}
