UITableViewController insert different cells into different sections - swift

Question

I have a TableViewController with 3 sections with their own headers.
Now I want before inserting any cell, check a property and then add the cell into different sections.
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// Table view cells are reused and should be dequeued using a cell identifier.
let cellIdentifier = "TasksTableViewCell"
guard let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as? TasksTableViewCell else {
fatalError("The dequeued cell is not an instance of TasksTableViewCell.")
}
// Fetches the appropriate task for the data source layout.
let task = tasks[indexPath.row]
cell.nameLabel.text = task.name
cell.photoImageView.image = task.photo
cell.timeControl.text = task.lengthDisplay.replacingOccurrences(of: "Length: ", with: "")
if(task.importanceLevel == 0){
// add cell to section 0
}
else if(task.importanceLevel == 1){
// add cell to section 1
}
// Configure the cell...
return cell
}
Can u see the comment, is there any way to do that?
Thank you very much

Answer 1

You can create a model and pass empty count arrays at first for each section and row in data source methods.
And then initialize the count and fill arrays their then reload your table view.
I hope you know there is numberOfSections method too.

Answer 2

I think this code will help you:
let arr = [5,2,7,10,2]
override func viewDidLoad() {
super.viewDidLoad()
}
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 5
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return arr[section]
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("celldata", forIndexPath: indexPath)
cell.textLabel?.text = "section \(indexPath.section)"
cell.detailTextLabel?.text = "Rows \(indexPath.row)"
return cell
}
override func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let view = UIView(frame: CGRect(x: 0, y: 0, width: self.tableView.frame.width, height: 20))
let lbl = UILabel(frame: CGRect(x: 5, y: 5, width: self.tableView.frame.width, height: 15))
lbl.text = "\(section)"
view.backgroundColor = UIColor.grayColor()
view.addSubview(lbl)
return view
}

You can try it like this
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if(indexPath.section == 0){
let cellIdentifier = "TasksTableViewCell"
guard let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as? TasksTableViewCell else {
fatalError("The dequeued cell is not an instance of TasksTableViewCell.")
}
// Fetches the appropriate task for the data source layout.
let task = tasks[indexPath.row]
cell.nameLabel.text = task.name
cell.photoImageView.image = task.photo
cell.timeControl.text = task.lengthDisplay.replacingOccurrences(of: "Length: ", with: "")
return cell
}
else if(indexPath.section == 1)
let cellIdentifier = "TasksTableViewCell1"
guard let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as? TasksTableViewCell1 else {
fatalError("The dequeued cell is not an instance of TasksTableViewCell.")
}
// Fetches the appropriate task for the data source layout.
let task = tasks[indexPath.row]
cell.nameLabel.text = task.name
cell.photoImageView.image = task.photo
cell.timeControl.text = task.lengthDisplay.replacingOccurrences(of: "Length: ", with: "")
return cell
}
}
