Passing ImageArray from Json File to ImageView Controller - json

Question

I'm Trying to have tableview with a search controller pass image Array from Json file to a new viewcontroller based on what option the user picks in search bar tableview. I have created a search bar for my App that displays will display all of the information in the app so the user can easily pick the pictures they want to see. That works normally by using a tableview, and when the user pick a row, it sends a variable with the associated pictures to an image view on the other screen.
Because of the amount of options I have, I created a Json file. I have it coded where it will return options based on what the user types into the search bar. My problem is that I am unable to pass the Image Array from the .json file to the image view controller. It will display the viewcontroller, but the "array" imageview is blank as no picture array is being passed. Below is my code and am wondering if anyone has any ideas that could point me in the right direction, or tell me what I am doing wrong.
Search Bar code:
import UIKit
class ProtocolCell: UITableViewCell {
#IBOutlet weak var pNameLabel: UILabel!
}
extension String {
func trimmed() -> String {
return self.trimmingCharacters(in: .whitespaces)
}
}
class SearchController: UIViewController, UISearchBarDelegate {
/// Search Bar
#IBOutlet weak var pSearchBar: UISearchBar!
/// Proto Array
fileprivate var myProtocols:[Protocols]?
/// Searhed Array
fileprivate var searchedProtocols:[Protocols]?
/// TableView
#IBOutlet weak var protocolsTV: UITableView!
/// Is Searching
fileprivate var isSearching:Bool=false
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
protocolsTV.tableFooterView=UIView()
pSearchBar.delegate=self
myProtocols=[Protocols]()
searchedProtocols=[Protocols]()
myProtocols?.removeAll()
searchedProtocols?.removeAll()
myProtocols=Functions.getAllProtocolsFromJson()
if protocolsTV.delegate == nil {
protocolsTV.delegate=self
protocolsTV.dataSource=self
}
protocolsTV.reloadData()
}
}
extension SearchController: UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return isSearching == false ? (myProtocols?.count ?? 0) : (searchedProtocols?.count ?? 0)
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "ProtocolCell") as! ProtocolCell
cell.pNameLabel.text=isSearching == false ? (myProtocols![indexPath.row].pName ?? "") : (searchedProtocols![indexPath.row].pName ?? "")
return cell
}
//EDIT TABLE FUNCTION HERE!!!!!//
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print("Is Searching: \(isSearching) ImagesArray: \(isSearching==true ? (searchedProtocols?[indexPath.row].imagesName ?? []) : (myProtocols?[indexPath.row].imagesName ?? []))")
let Vc = self.storyboard?.instantiateViewController(withIdentifier: "imageViewController") as! imageViewController
let home = self.storyboard?.instantiateViewController(withIdentifier: "FIRST") as! ViewController
//switch indexPath.section
// {
// case 0:
if searchedProtocols?[indexPath.row].pName == "test" {
let arrayStorage = myProtocols?[indexPath.row].imagesName ?? []
Vc.passedArray = arrayStorage
print(arrayStorage)
print(myProtocols?[indexPath.row].imagesName ?? [])
self.navigationController?.pushViewController(Vc, animated: true)
}
else {
self.navigationController?.pushViewController(home, animated: true)
}
// break;
// default:
// self.navigationController?.pushViewController(home, animated: true)
// }
}
func updateSearchData(With searchText: String, In searchBar: UISearchBar) {
if searchText.trimmed().count == 0 {
isSearching=false
searchBar.setShowsCancelButton(false, animated: true)
} else {
isSearching=true
searchBar.setShowsCancelButton(true, animated: true)
}
if isSearching {
/// We Are Searching Sort Array
if searchedProtocols == nil { searchedProtocols=[Protocols]() }
searchedProtocols?.removeAll()
searchedProtocols=myProtocols!.filter({($0.pName ?? "").lowercased().contains(searchText.lowercased())})
/// Make Set So, Data isn't Repeated
searchedProtocols=Array(Set(searchedProtocols ?? []))
} else {
/// Searching is Stopped
searchedProtocols?.removeAll()
}
protocolsTV.reloadData()
}
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
updateSearchData(With: searchText, In: searchBar)
}
func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
self.view.endEditing(true)
}
func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
searchBar.setShowsCancelButton(false, animated: true)
searchBar.text=nil
isSearching=false
searchedProtocols?.removeAll()
protocolsTV.reloadData()
self.view.endEditing(true)
}
}
Other Used Code:
class Protocols: NSObject {
var pName:String?
var imagesName:[UIImage]!
override init() {}
init(With Dict: [String:Any]) {
pName=Dict["name"] as? String ?? ""
imagesName=Dict["imagesArray"] as? [UIImage] ?? []
}
ImageViewController:
class imageViewController: UIViewController,GADBannerViewDelegate, UIGestureRecognizerDelegate, UIScrollViewDelegate {
#IBOutlet weak var pageControl: UIPageControl!
var bannerView: GADBannerView!
var index = 0
var mySelectedProtocol:Protocols?
#IBOutlet weak var scrollView: UIScrollView!
#IBOutlet weak var myImageView: UIImageView!
#IBAction func pictureSwipe(_ sender: Any) {
let pictureString = self.passedArray[index]
self.myImageView.image = pictureString
index = (index < passedArray.count-1) ? index+1 : 0
self.pageControl.numberOfPages = passedArray.count
self.pageControl.currentPage = index
}
#IBAction func pictureswipeback(_ sender: Any) {
let pictureString = self.passedArray[index]
self.myImageView.image = pictureString
index = (passedArray.count-1)
self.pageControl.numberOfPages = passedArray.count
self.pageControl.currentPage = index
}
func configurePageControl() {
self.pageControl.numberOfPages = passedArray.count
self.pageControl.currentPage = 0
self.pageControl.pageIndicatorTintColor = UIColor.white
self.pageControl.currentPageIndicatorTintColor = UIColor.red
self.view.addSubview(pageControl)
if index == 1 {
self.pageControl.currentPage = 1
}
func updateCurrentPageDisplay(){
self.pageControl.numberOfPages = passedArray.count
}
}
var passedImage : UIImage! = nil
var passedArray : [UIImage]!
override func viewDidLoad(){
super.viewDidLoad()
self.myImageView.image = passedArray.first
configurePageControl()
scrollView.delegate = self
self.navigationController?.navigationBar.isHidden = false
scrollView.minimumZoomScale = 1.0
scrollView.maximumZoomScale = 5.0

Answer 1

In Destination Controller
class DestinationVC: UIViewController {
var mySelectedProtocol:Protocols?
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
if mySelectedProtocol == nil { self.navigationController?.popViewController(animated: true) }
/// We have Data
print("Img Array with Name ==> \(mySelectedProtocol?.imagesName ?? [])")
}
}
In Source Controller TableView Delegate
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print("Is Searching: \(isSearching) ImagesArray: \(isSearching==true ? (searchedProtocols?[indexPath.row].imagesName ?? []) : (myProtocols?[indexPath.row].imagesName ?? []))")
let vc:DestinationVC=mainStoryBoard.instantiateViewController(withIdentifier: "DestinationVC") as! DestinationVC
vc.mySelectedProtocol=isSearching==true ? (searchedProtocols?[indexPath.row]) : (myProtocols?[indexPath.row])
self.navigationController?.pushViewController(vc, animated: true)
}
Update 2 - Show Images as PageViewController
private func addPageView() {
myScrollView.backgroundColor=UIColor.clear
myScrollView.isUserInteractionEnabled=true
myScrollView.showsHorizontalScrollIndicator=false
myScrollView.isPagingEnabled=true
myScrollView.delegate=self
myScrollView.bounces=false
self.count=mySelectedProtocol!.imagesName!.count
for i in 0..<self.count {
///Get Origin
let xOrigin : CGFloat = CGFloat(i) * myScrollView.frame.size.width
///Create a imageView
let imageView = UIImageView()
imageView.frame = CGRect(x: xOrigin, y: 0, width: myScrollView.frame.size.width, height: myScrollView.frame.size.height)
imageView.contentMode = .scaleAspectFit
imageView.image=UIImage(named: mySelectedProtocol!.imagesName![i])
myScrollView.addSubview(imageView)
}
setUpPageControl()
///Set Content Size to Show
myScrollView.contentSize = CGSize(width: myScrollView.frame.size.width * CGFloat(self.count), height: myScrollView.frame.size.height)
}
