I have a table view with a "like" button. Users can tap to like the content in each cell. I want to use UserDefaults to persist the button status so that it gets saved if a user closes the app. I'm a new developer so I was hoping for guidance on getting started.
Here is the code for the table view cell: import UIKit
class QuotesTableViewCell: UITableViewCell {
@IBOutlet weak var likeButton: UIButton!
@IBOutlet weak var quoteLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
@IBAction func likeTapped(_ sender: UIButton) {
if likeButton.tag == 0{
likeButton.setImage(UIImage(named: "GreenHeart"), for: .normal)
likeButton.tag = 1
} else{
likeButton.setImage(UIImage(named: "blankHeart"), for: .normal)
likeButton.tag = 0
}
}
}
And here is the code for the view controller:
import UIKit
class QuotesMainViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet weak var quotesTableView: UITableView!
let quoteList = ["Quote1", "Quote2", "Quote3"]
override func viewDidLoad() {
super.viewDidLoad()
quotesTableView.delegate = self
quotesTableView.dataSource = self
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return quoteList.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = quotesTableView.dequeueReusableCell(withIdentifier: "cell") as! QuotesTableViewCell
cell.quoteLabel.text = quoteList[indexPath.row] as! String
return cell
}
}
