Swift Multi Selection Problem Uitableview

Question

I have a tableView that when it is in "Edit" mode I can select each item and take an action, for example remove the selected items.

When I select the items, the first ones are left without "Line division", and the lower ones are selected normally as shown in the following print:

What can it be? An Xcode bug or is there an implementation that fixes it?

When I scroll down the top ones also disappear the dividing edge of the tableView.

Answer 1

Does this problem occur on iOS 7 or iOS 8? Or both?

To UITableView in iOS uses a concept of "recycling" the ballots. Every time you use the scroll of table view it recharges the ballots. You can solve this problem in a few different ways.

If it’s iOS 7, you can reset the style of the tab table view

Using the methods delegate of table you reset the style of the ballots.

func tableView(tableView: UITableView, didHighlightRowAtIndexPath indexPath: NSIndexPath) {
        // Redefinindo o estilo do separador
        tableView.separatorStyle = UITableViewCellSeparatorStyle.None;
        tableView.separatorStyle = UITableViewCellSeparatorStyle.SingleLine;
}

func tableView(tableView: UITableView, didUnhighlightRowAtIndexPath indexPath: NSIndexPath) {
        // Redefinindo o estilo do separador
        tableView.separatorStyle = UITableViewCellSeparatorStyle.None;
        tableView.separatorStyle = UITableViewCellSeparatorStyle.SingleLine;
    }

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        // Redefinindo o estilo do separador
        tableView.separatorStyle = UITableViewCellSeparatorStyle.None;
        tableView.separatorStyle = UITableViewCellSeparatorStyle.SingleLine;
}

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        // Por garantia também redefine o estilo do separador ao selecionar a cédula
        tableView.separatorStyle = UITableViewCellSeparatorStyle.None;
        tableView.separatorStyle = UITableViewCellSeparatorStyle.SingleLine;
 }

If you use customized ballots

You have to register the ballot on viewDidLoad.

self.tableView.registerClass(CustomClassCell.classForCoder(), forCellReuseIdentifier: "Cell")

More drastic solution if none of these works

You can add a UIView gray color with height of 1 at the bottom of the ballot and remove the style of the separator by setting the style to None. But it wouldn’t be best practice.

EDIT

Solution with ballots loaded from a nib

To create the ballot from a Nib, in viewDidLoad you must register the identifier of the same:

override func viewDidLoad() {
     super.viewDidLoad()
     self.tableView.registerNib(UINib(nibName: "CellNibName", bundle: nil), forCellReuseIdentifier: "Cell")
}

In the method cellForRowAtIndexPath:

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! CustomClassCell
     .
     .
     .
     return cell
}

I’ve never worked with custom ballots, but let’s see what I can do to help. Make sure your tableView features Note Separator attributes in the default

.

Also ensure the same attribute on the ballot itself

And lastly make sure you don’t have more than one ballot on the tableView containing different attributes.
