How to enlarge tableView on scroll? - ios

Question

I'm sorry if this is a duplicate. I tried to review similar questions in SO - still doesn't quite make me understand how to deal with this.
I have a tableView, three textViews and a UIButton. When the user scrolls the tableView, the tableView should pushes the textFields and the button out the image and take up more space. When that is done I want to continue scrolling through the cells.
(I want one of the textFields to always remain and still show the title.)
I think I need to put the textViews and button above the tableView inside a tableView header after which I need to set certain constraints between the UIView above the tableView and tableView itself. Then I need to play around with the UIScrollViewDelegate and calculate something.
As you guys can probably tell, I'm relatively new in programming and I believe this i why I don't quite understand the related questions. And as you can probably tell too, why I am pretty damn confused about how to solve my problem!
Here's a photo of the VC:
I wan't the tableView to go and cover the 'AddNewPersonBtn' and the two bottom textView - leaving only the top textView, the navigationBar and the tableView on the screen. --> Until you then scroll down again and the rest will be visible again.
And here goes the code for the VC:
import UIKit
import RealmSwift
class AllPersonsInYourDiary: UIViewController, UITableViewDelegate, UITableViewDataSource {
var diary: Diaries?
#IBOutlet weak var tableView: UITableView!
#IBOutlet weak var showingDiaryName: UILabel!
#IBOutlet weak var showingDiaryQuestion: UILabel!
#IBOutlet weak var showingExtraIdentifer: UILabel!
#IBOutlet weak var diaryTheme: UIImageView!
#IBOutlet weak var diaryPhoto: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.tableFooterView = UIView()
self.tableView.tableHeaderView = UIView()
}
override func viewWillAppear(_ animated: Bool) {
tableView.reloadData()
showDiaryIdentifiers()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
#IBAction func createNewPersonButton () {
let controller = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier:

controller.mode = .create
controller.diary = diary
self.navigationController?.pushViewController(controller, animated: true)
}
#IBAction func showEditFunc () {
let controller = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "SettingsVC") as! SettingsVC
controller.diary = diary
self.navigationController?.pushViewController(controller, animated: true)
}
func showDiaryIdentifiers () {
self.showingDiaryName.text = diary?.diaryName
self.showingDiaryQuestion.text = diary?.diaryQuestion
self.showingExtraIdentifer.text = diary?.diaryExtraIdentifier
self.diaryTheme.image = UIImage(data: diary?.diaryTheme ?? Data()) ?? UIImage(named: "Blank")
// self.diaryPhoto.image = UIImage(data: diary?.diaryPhoto ?? Data ()) ?? UIImage(named: "Blank")
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return diary!.people.count
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 100
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Person1", for: indexPath) as! PersonCell
let date = DateFormatter.localizedString(from: (diary?.people[indexPath.row].dateCreated)!, dateStyle: .short, timeStyle: .none)
cell.personName.text = diary?.people[indexPath.row].name
cell.personAnswer.text = date
cell.personPhoto.image = UIImage(data: diary?.people[indexPath.row].photo ?? Data()) ?? UIImage(named: "PortaitPhoto")
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let controller = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier:

let realm = try! Realm()
try! realm.write {

return
}
self.diary!.people.remove(at: indexPath.row)

}
tableView.deleteRows(at: [indexPath], with: .fade)
