所以这是TableView的结构:
有一个主要的 UITableView ，在每个 UITableViewCell 内，还有另一个 UITableview
屏幕截图:
每个 UITableViewCells 被设计为“自定义视图”，并且是通过从Nib中将其加载到 cellForRowAtIndexPath 函数中而添加的。
我想对内部“表视图”中选择的任何选项进行操作，我想获取“表视图”所嵌入单元格的索引路径。
文件格式:
我尝试遵循 Paulw11 在此处提到的代理方法:
swift: how to get the indexpath.row when a button in a cell is tapped?: StackOverflow
注意: Paulw11推荐的方法可以完美地工作
代码(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)
}}
代码(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!)
}}
代码(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O / P为 nil
注意:根据 pbasdf 的注释更改了代码，实现了该错误
最佳答案
@Supratik Majumdar请求添加了以下答案，以回答我所说的逻辑。
Supratik尝试使用以下代码，希望您能完成您的需求。
//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
}
