I've looked at a lot of other questions on this subject. But they all lead to the same thing "view did load" "view did appear" and "view will appear" and Ive put
tableview.reloadData()
in all of them but after dismissal of the modal view it still doesn't reload till I terminate the app and then I run again. I have seen that you can do this with notification center and have seen that Here and I tried that method but it didn't seem to work for me. Thanks for any Help in advance!!!
import UIKit
class mainScreen: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet weak var tableview: UITableView!
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
// MARK: - Table View Setup
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if allPeople.count == theAssignments.count {
return allPeople.count
}else {
print("else in number of rows in section BAD")
return allPeople.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "PeopleTVCell", for: indexPath)
cell.textLabel?.text = theAssignments[indexPath.row]
cell.detailTextLabel?.text = allPeople[indexPath.row]
return cell
}
// MARK: - System setup
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
tableview.allowsSelection = false
/////////here
tableview.reloadData()
}
override func viewWillAppear(_ animated: Bool) {
////////here
tableview.reloadData()
}
override func viewDidAppear(_ animated: Bool) {
let NamesObject = UserDefaults.standard.object(forKey: "Name" + whatGroup)
if let tempItems = NamesObject as? [String] {
allPeople = tempItems
print("saved data in main (Name)")
}
let AssignmentObject = UserDefaults.standard.object(forKey: whatGroup + "Assignment")
if let tempItems = AssignmentObject as? [String] {
theAssignments = tempItems
print("saved data in main (Assignments)")
}
////////here
tableview.reloadData()
}
// MARK: - the Exit Segue
@IBAction func exitSegue(segue: UIStoryboardSegue) {
/////////here
tableview.reloadData()
isAddingName = 2
print("Exited to main")
}
}
this is where I would add things
@IBAction func saveButton(_ sender: UIButton) {
if isInMain == true {
if IsAddingAssignment == true {
// MARK: Add Assignment
let AssignmentObject = UserDefaults.standard.object(forKey: whatGroup + "Assignment") as? [String]
var Assignment: [String]
if let tempItems = AssignmentObject {
Assignment = tempItems
Assignment.append("\(EnteredObjectTextFeild.text!)")
print(Assignment)
} else {
Assignment = [EnteredObjectTextFeild.text!]
print("user defaults error 2")
}
UserDefaults.standard.set(Assignment, forKey: whatGroup + "Assignment")
EnteredObjectTextFeild.text = ""
}else {
// MARK: Add Name
if AllNames.contains("\(EnteredObjectTextFeild.text!)"){
if namesForEachGroup.contains(EnteredObjectTextFeild.text!) {
EnteredObjectTextFeild.text = ""
AlertAction(Title: "Name Exists", Message: "This name already exists in this group", alerTitle: "OK")
}else {
addNameToGroup()
EnteredObjectTextFeild.text = ""
}
}else {
let NameObject = UserDefaults.standard.object(forKey: "Name") as? [String]
var Name: [String]
if let tempItems = NameObject {
Name = tempItems
Name.append("\(EnteredObjectTextFeild.text!)")
print(Name)
} else {
Name = [EnteredObjectTextFeild.text!]
print("user defaults error 3")
}
UserDefaults.standard.set(Name, forKey: "Name")
addNameToGroup()
EnteredObjectTextFeild.text = ""
NamePicker.reloadAllComponents()
AsignmentPicker.reloadAllComponents()
}
}
}else if isInMain == false {
// MARK: Add Group
if allGroups.contains("\(EnteredObjectTextFeild.text!)"){
EnteredObjectTextFeild.text = ""
AlertAction(Title: "Group Exists", Message: "This Group already exists", alerTitle: "OK")
}else {
let groupsObject = UserDefaults.standard.object(forKey: "Groups") as? [String]
var groups: [String]
if let tempItems = groupsObject {
groups = tempItems
groups.append(EnteredObjectTextFeild.text!)
print(groups)
} else {
groups = [EnteredObjectTextFeild.text!]
print("Bad")
}
UserDefaults.standard.set(groups, forKey: "Groups")
EnteredObjectTextFeild.text = ""
}
NamePicker.reloadAllComponents()
AsignmentPicker.reloadAllComponents()
}
NamePicker.reloadAllComponents()
AsignmentPicker.reloadAllComponents()
}
// MARK: Add Name func
func addNameToGroup(){
let nameObject = UserDefaults.standard.object(forKey: "Name" + whatGroup) as? [String]
var NameForGroup: [String]
if let tempItems = nameObject {
NameForGroup = tempItems
NameForGroup.append("\(EnteredObjectTextFeild.text!)")
print(NameForGroup)
} else {
NameForGroup = [EnteredObjectTextFeild.text!]
print("user defaults error 4")
}
UserDefaults.standard.set(NameForGroup, forKey: "Name" + whatGroup)
namesForEachGroup = NameForGroup
print("saved to group")
EnteredObjectTextFeild.text = ""
NamePicker.reloadAllComponents()
AsignmentPicker.reloadAllComponents()
}
and this is where I get back to the first VC
@IBAction func BackPressed(_ sender: UIButton) {
if isInMain == true {
performSegue(withIdentifier: "FromAddToMain", sender: UIButton())
}else {
performSegue(withIdentifier: "FromAddToGroup", sender: UIButton())
}
}
