我已经在swift中实现了Tableview,但是我想制作可扩展的Tableview请给出这个想法。。
这是Tableview的代码。。
//MARK: - TableView Delegate and Datasource
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return MenuNameArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "MenuTableViewCell", for: indexPath) as! MenuTableViewCell
cell.menuNameLabel.text = NameArray[indexPath.row]
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
}
最佳答案
给你,试试这个:-
struct ExpandableNames {
var isExpanded : Bool
var names : [String]
}
struct Contact {
let names : String
}
在您的班级->
var twoDArray = [
ExpandableNames(isExpanded : true,names:["Krishna","Rishabh","Aditya","Chandan","Nipun","Navdeesh","Steve"].map
{
Contact(names: $0)
}),
ExpandableNames(isExpanded : true,names:["Carl","Michal","Tommy","Jennny","Vikram","Swati"].map
{
Contact(names: $0)
}),
ExpandableNames(isExpanded : true,names:["David","dude","dfff","dcc","daa","dee","dsss"].map
{
Contact(names: $0)
}),
ExpandableNames(isExpanded : true,names:[Contact(names: "Pattrick", hasFav: false)])
]
let cellId = "cellID"
let identifier = "attachmentCellID"
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat
{
return 50
}
func numberOfSections(in tableView: UITableView) -> Int
{
return twoDArray.count
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
if !twoDArray[section].isExpanded
{
return 0
}
return twoDArray[section].names.count
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
{
let btn = UIButton(type: .system)
if(section == 0)
{
btn.setTitle("Tap To View Classes", for: .normal)
}
else if(section == 1)
{
btn.setTitle("Tap To View Admins", for: .normal)
}
btn.setTitleColor(.black, for: .normal)
btn.titleLabel?.font = UIFont.boldSystemFont(ofSize: 14)
btn.addTarget(self, action: #selector(handleExpandClose), for: .touchUpInside)
btn.backgroundColor = AppColors.greyBorderColor
btn.tag = section
return btn
}
@objc func handleExpandClose(button : UIButton)
{
let section = button.tag
var indexPaths = [IndexPath]()
for row in twoDArray[section].names.indices
{
let indexPath = IndexPath(row: row, section: section)
indexPaths.append(indexPath)
}
let isExpanded = twoDArray[section].isExpanded
twoDArray[section].isExpanded = !isExpanded
button.setTitle(isExpanded ? "Tap To View Classes" : "Classes", for: .normal)
if isExpanded
{
tableView.deleteRows(at: indexPaths, with: .fade)
}
else
{
tableView.insertRows(at: indexPaths, with: .fade)
}
}
在牢房休息-
let contact = twoDArray[indexPath.section].names[indexPath.row]
cell.textLabel?.text = contact.names
