我想从TableViewCell
TextFields
得到所有值,但我不明白我怎么可以通过点击按钮做。
我可以添加新行,如果我点击按钮Add
。所以,我想我可以使尽可能多的行。
我的代码在这里:
struct Section {
let title: String
var rows: [String]
}
class SettingsScheduleAndPricesViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UITextFieldDelegate {
var hall: Halls?
var sections = [Section]()
override func viewDidLoad() {
super.viewDidLoad()
sections = [Section(title: "Day of week", rows: []),
Section(title: "Second section", rows: [""]),
Section(title: "Third section", rows: [""])]
}
// MARK: - TableView
func numberOfSections(in tableView: UITableView) -> Int {
return sections.count
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return sections[section].rows.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.section == 0 {
...
} else if indexPath.section == 1 {
let hourlyRateCell = tableView.dequeueReusableCell(withIdentifier: "hourlyRateCell", for: indexPath) as! SettingsHourlyRateCell
return hourlyRateCell
} else {
...
}
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return sections[section].title
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let frame: CGRect = tableView.frame
if section == 0 {
let headerView: UIView = UIView(frame: CGRect(x: 0, y: 0, width: frame.size.width, height: frame.size.height))
headerView.backgroundColor = #colorLiteral(red: 0.8039215803, green: 0.8039215803, blue: 0.8039215803, alpha: 1)
return headerView
} else if section == 1 {
let addButton: UIButton = UIButton(frame: CGRect(x: frame.size.width - 50, y: 0, width: 50, height: 30))
addButton.backgroundColor = UIColor.clear
addButton.setTitleColor(#colorLiteral(red: 0.2588235438, green: 0.7568627596, blue: 0.9686274529, alpha: 1), for: .normal)
addButton.setTitle(NSLocalizableAdd, for: .normal)
addButton.addTarget(self, action: #selector(SettingsScheduleAndPricesViewController.addHourlyRate(sender:)), for: .touchUpInside)
let headerView: UIView = UIView(frame: CGRect(x: 0, y: 0, width: frame.size.width, height: frame.size.height))
headerView.backgroundColor = #colorLiteral(red: 0.8039215803, green: 0.8039215803, blue: 0.8039215803, alpha: 1)
headerView.addSubview(addButton)
return headerView
} else {
...
}
}
@IBAction func saveBarButtonPressed(_ sender: Any) {
// here I want to get all values from my Cell from my TextFields
}
@objc func addHourlyRate(sender: UIButton) {
let newRow = ""
append(row: newRow, in: 1)
}
func append(row : String, in section: Int) {
let insertionIndex = sections[section].rows.count
sections[section].rows.append(row)
let indexPath = IndexPath(row: insertionIndex, section: section)
tableView.insertRows(at: [indexPath], with: .automatic)
}
}
class SettingsHourlyRateCell: UITableViewCell, UITextFieldDelegate {
@IBOutlet weak var rubHourTF: UITextField!
}
从模拟器我的例子:
在我的例子我需要从三排得first
,second
和third
字符串文本。而在空array
追加或只是console
打印。
在方法@IBAction func saveBarButtonPressed(_ sender: Any)
。
我找不到任何可以帮助我。
在TableView中细胞的TextField可能会非常棘手。首先,使用的数据模型和reloadData(),而不是insertRows(在:)这样的:
@objc func addHourlyRate(sender: UIButton) {
let newRow: String = ""
secondRowText.append(newRow)
self.tableView.reloadData()
}
现在,设置在单元格中的文本,并在cellForRowAt()这样的行号标记的的UITextField:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let hourlyRateCell = tableView.dequeueReusableCell(withIdentifier: "hourlyRateCell", for: indexPath) as! SettingsHourlyRateCell
hourlyRateCell.rubHourTF.text = secondRowText[indexPath.row]
hourlyRateCell.rubHourTF.tag = indexPath.row
return hourlyRateCell
}
接下来,使用UITextFieldDelegate保持在文本字段中的任何改变,像跟踪:
func textFieldDidEndEditing(_ textField: UITextField) {
let tableRow = textField.tag
secondRowText[tableRow] = textField.text
}
请注意,在cellForRow()设置的文本字段标签现在是如何用于了解文本字段是在表中哪一行。
你可以做一个委托协议,为您的电池
protocol cellDelegate {
func buttonClicked(textFieldText: String)}
使您的协议的一个变量,你的
var delegate: cellDelegate?
然后按一下按钮事件调用从变量的方法
delegate?.buttonClicked(textFieldText: "string you got from textField")
并在表视图cellForRowAt indexPath方法这样设置电池的代表:cell.delegate = self
也许我的方法帮助别人,但我仍设法做这种方式。我只添加我button
这样的代码:
@IBAction func saveBarButtonPressed(_ sender: Any) {
let countRowsOne = tableView.numberOfRows(inSection: 1)
for index in 0...countRowsOne {
let indexPath = IndexPath(row: index, section: 1)
if let cell = tableView.cellForRow(at: indexPath) as? SettingsHourlyRateCell {
...
}
...
}
}
}
无需标签
@IBAction func saveBarButtonPressed(_ sender: Any) {
var array = NSMutableArray()
for subview in self.tableView.subViews {
if subView.isKind(of: String(describing: SettingsHourlyRateCell.self)) {
for sView in subview {
if sView.isKind(of: String(describing: UITextField.self)) {
array.add(sView.text)
}
}
}
}
}
