Я добавил стрелку, чтобы сложить раздел при щелчке, когда я складываю последний раздел (например, при установке высоты строки на 0 в cellForRow
, все строки в последнем разделе смешиваются, как это видно на изображение ниже:
Может кто-нибудь предложить какую-либо причину, почему это должно произойти, если я устанавливаю высоту строки в 0?
Вот соответствующий код :
viewForHeaderInSection:
override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
if section == 0 {
let profileCompletion = clientFields?.profileCompletion ?? 0
headerView.profileComplete.text = "Profile".localized() + " \(profileCompletion)% " + "Complete".localized()
headerView.profileProgress.progress = Float(profileCompletion) * 0.01
headerView.profileProgress.progressTintColor = Constants.Client.getProfileCompletenessColor(profileCompletion)
headerView.delegate = self
headerView.section = section
headerView.isOpen = self.sectionsStatuses[section].shouldDisplaySection
return headerView
}
else {
let height = (section == 0) ? FIRST_HEADER_HEIGHT : HEADER_HEIGHT
let nib = UINib(nibName: "ClientDetailsSectionHeaderCell", bundle: nil)
guard let returnedView = nib.instantiate(withOwner: self, options: nil)[0] as? ClientDetailsSectionHeaderCell else {
return UIView()
}
returnedView.delegate = self
returnedView.section = section
returnedView.isOpen = self.sectionsStatuses[section].shouldDisplaySection
returnedView.frame = CGRect(x: 0, y: 0, width: view.frame.size.width, height: height)
returnedView.heightConstraint.constant = height
returnedView.mainView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
returnedView.mainView.backgroundColor = Constants.ParentForm.headerBgColor
// Draw separators
if DRAW_SECTION_SEPARATORS || DRAW_SECTION_TOP_SEPARATOR {
returnedView.createTopSeparator(color: Constants.ParentForm.separatorColor)
}
if DRAW_SECTION_SEPARATORS || DRAW_SECTION_BOTTOM_SEPARATOR {
returnedView.createBottomSeparator(color: Constants.ParentForm.separatorColor)
}
if isSectionTitleHidden == false {
let xOffset = HEADER_X_OFFSET
let yOffset = section == 0 ? FIRST_HEADER_Y_OFFSET : HEADER_Y_OFFSET
returnedView.title.frame = CGRect(x: xOffset, y: yOffset, width: view.frame.size.width - xOffset, height: height - yOffset)
returnedView.title.text = self.sectionsArray[section].uppercased().localized()
returnedView.title.font = Constants.ParentForm.headerFont
returnedView.title.textColor = Constants.ParentForm.headerTextColor
returnedView.title.sizeToFit()
}
return returnedView
}
}
heightForRow
override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
if sectionsStatuses[indexPath.section].shouldDisplaySection {
return super.tableView(tableView, heightForRowAt: indexPath)
}
return CGFloat(0)
}
cellForRow
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if self.sectionsArray[indexPath.section] != "ADDRESSES" {
if let clientFields = self.clientFields {
self.dataMap = Utils.convertObjectToMap(item: clientFields)
let birthdayDate = clientFields.birthdayDateString
self.dataMap["birthdayDate"] = birthdayDate
let createdDate = clientFields.createdDateString
self.dataMap["createdDate"] = createdDate
}
}
else {
if let clientAddresses = self.clientAddresses, clientAddresses.count > 0 {
self.dataMap = Utils.convertObjectToMap(item: clientAddresses[Int(floor(Double(indexPath.row) / 8.0))])
}
}
return super.tableView(tableView, cellForRowAt: indexPath)
}
функция протокола
func openCloseSection(openSection: Bool, section: Int) {
self.sectionsStatuses[section].shouldDisplaySection = openSection
self.tableView.reloadData()
}
