Hide Background View from Table View Controller - swift

Question

I have just added a placeholder label to display text when my table view is empty however I can't figure out how to dismiss the background view once a new cell has been added.
This is how the table view looks once a cell has been added:
This is the code I am using to display the label:
override func tableView(tableView: UITableView?, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete method implementation.
// Return the number of rows in the section.
println(arrayObject.paymentsArray().count)
if arrayObject.paymentsArray().count == 0 {
backgroundLabel.text = "You haven't added any transactions yet. Tap the add button to add a new transaction."
backgroundLabel.frame = CGRectMake(0, 0, self.view.bounds.width, self.view.bounds.height)
backgroundLabel.numberOfLines = 0
backgroundLabel.textAlignment = NSTextAlignment.Center
backgroundLabel.sizeToFit()
self.tableView.backgroundView = backgroundLabel
self.tableView.separatorStyle = UITableViewCellSeparatorStyle.None
return 0
} else {
return arrayObject.paymentsArray().count
}
}
How can I dismiss the background label once a the arrayObject.paymentsArray().count does not equal 0?
EDIT:
I changed the code to this:
override func tableView(tableView: UITableView?, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete method implementation.
// Return the number of rows in the section.
println(arrayObject.paymentsArray().count)
if arrayObject.paymentsArray().count == 0 {
backgroundLabel.text = "You haven't added any transactions yet. Tap the add button to add a new transaction."
backgroundLabel.frame = CGRectMake(0, 0, self.view.bounds.width, self.view.bounds.height)
backgroundLabel.numberOfLines = 0
backgroundLabel.textAlignment = NSTextAlignment.Center
backgroundLabel.sizeToFit()
backgroundLabel.hidden = false
self.tableView.backgroundView = backgroundLabel
self.tableView.separatorStyle = UITableViewCellSeparatorStyle.None
return 0
} else {
backgroundLabel.hidden = true
return arrayObject.paymentsArray().count
}
}
This now hides the message as intended however the table view has lost the dividing lines in between the cells.

You need to keep a reference to your background label (say as a property of your viewController) and then set hidden equal to true e.g.
self.backgroundLabel.hidden = true on the label in your else clause.else
{
self.backgroundLabel.hidden = true
return arrayObject.paymentsArray().count
}
To get your lines back you need to set the separator style, you set it to none - you need single line.
{
self.backgroundLabel.hidden = true
return arrayObject.paymentsArray().count
self.tableView.separatorStyle = UITableViewCellSeparatorStyle.SingleLine
}
