我正在为我的学校在Swift做一个项目，在那里我在TableView中显示数据。它显示两天，实际日期和第二天的信息。现在我想将表拆分为每天两个部分。如果可能的节标题包含每个节的日期。如果我已经拥有带有数据的TableView，我该怎么做呢。最好的祝福。 ;）

尝试检查代码 - https://github.com/RockinGarg/Expandable-TableView-.git
必填代码
//setting number of Sections
func numberOfSections(in tableView: UITableView) -> Int {
return section.count
}
如果要自定义headerView
//Setting Header Customised View
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
//Declare cell
let headerCell = tableView.dequeueReusableCell(withIdentifier: "HeaderCell") as! TableViewCell
//Setting Header Components
headerCell.titleLabel.text = self.section[section]
headerCell.ButtonToShowHide.tag = section
//Handling Button Title
if self.collapaseHandlerArray.contains(self.section[section]){
//if its opened
headerCell.ButtonToShowHide.setTitle("Hide", for: .normal)
}
else{
//if closed
headerCell.ButtonToShowHide.setTitle("Show", for: .normal)
}
//Adding a target to button
headerCell.ButtonToShowHide.addTarget(self, action: #selector(ViewController.HandleheaderButton(sender:)), for: .touchUpInside)
return headerCell.contentView
}
行数
//Setting number of rows in a section
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if self.collapaseHandlerArray.contains(self.section[section]){
return items[section].count
}
else{
return 0
}
}
您必须定义要显示的部分的数量：
func numberOfSections(in tableView: UITableView) -> Int {
return 2
}
然后，您必须定义要在每个部分中显示的行数：
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if section == 0 {
//return number of rows in first section
}
else {
//return number of rows in second section
}
}
如果要创建自定义标头，则可以使用此功能：
func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
// return custom header view
}
但是，如果只想在标题中显示文本，则可以使用默认文本并仅使用titleForHeaderInSection函数。
当然，您还必须返回正确的单元格视图。如果您想查看部分编号，可以直接致电
indexPath.section
你有没有尝试过UITableViewDataSource中的这个func：
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return yourDateString
}
