UIView inside UIView with TextField and Button not working - ios

Question

Good afternoon,
I'm trying to show a UIView when (in my case) there isn't any result to show in a tableView filled with products. When I detect 0 products, I show a UIView which contains a Label, a TextField and a Button, but I can't interact with my TextField and neither with the Button.
It's my first time using this technique to show a UIView when something went wrong with the tableView so I would like to know what's wrong in my code and what I'm missing because it's really weird.
Here is my code (when I print "Product not found" is where I show the UIView):
import UIKit
import Social
class ProductoCamViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
#IBOutlet var productoImageView:UIImageView!
#IBOutlet var tableView:UITableView!
#IBOutlet weak var noEncontrado:UIView!
var productoImage:String!
var ean:String!
var producto:Producto!
var productos = [Producto]()
#IBOutlet weak var toolBar: UIToolbar!
#IBOutlet weak var cargando: UIActivityIndicatorView!
override func viewDidLoad() {
toolBar.hidden = true
noEncontrado.hidden = true
cargando.hidden = false
super.viewDidLoad()
// Set table view background color
self.tableView.backgroundColor = UIColor(red: 240.0/255.0, green: 240.0/255.0, blue: 240.0/255.0, alpha: 0.2)
// Remove extra separator
self.tableView.tableFooterView = UIView(frame: CGRectZero)
// Change separator color
self.tableView.separatorColor = UIColor(red: 240.0/255.0, green: 240.0/255.0, blue: 240.0/255.0, alpha: 0.8)
self.tableView.rowHeight = UITableViewAutomaticDimension
self.tableView.estimatedRowHeight = 88.0
requestPost()
cargando.hidden = true
tableView.reloadData()
}
override func viewDidAppear(animated: Bool) {
tableView.reloadData()
}
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
self.navigationController?.hidesBarsOnSwipe = false
self.navigationController?.setNavigationBarHidden(false, animated: true)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
func requestPost () {
let request = NSMutableURLRequest(URL: NSURL(string: "http://www.mywebsite.com/product.php")!)
request.HTTPMethod = "POST"
let postString = "ean="+ean
request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
data, response, error in
if error != nil {
print("error=\(error)")
return
}
// JSON RESULTADO ENTERO
let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding)!
if (responseString == "Product not found")
{
self.noEncontrado.hidden = false
self.tableView.reloadData()
return
}
else
{
self.productos = self.parseJsonData(data!)
self.toolBar.hidden = false
// Reload table view
dispatch_async(dispatch_get_main_queue(), {
self.tableView.reloadData()
})
}
}
task.resume()
}
func parseJsonData(data: NSData) -> [Producto] {
var productos = [Producto]()
do {
let jsonResult = try NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers) as? NSDictionary
noEncontrado.hidden = true
// Parse JSON data
let jsonProductos = jsonResult?["lista_productos"] as! [AnyObject]
for jsonProducto in jsonProductos {
let producto = Producto()
producto.imagen = jsonProducto["imagen"] as! String
producto.nombre = jsonProducto["nombre"] as! String
producto.descripcion = jsonProducto["descripcion"] as! String
producto.modo_de_empleo = jsonProducto["modo_de_empleo"] as! String
producto.marca = jsonProducto["marca"] as! String
producto.linea = jsonProducto["linea"] as! String
producto.distribuidor = jsonProducto["distribuidor"] as! String
producto.tamano = jsonProducto["tamano"] as! String
producto.precio = jsonProducto["precio"] as! String
producto.codigo_nacional = jsonProducto["codigo_nacional"] as! String
productos.append(producto)
}
}
catch let parseError {
print(parseError)
}
return productos
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// Return the number of sections.
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// Return the number of rows in the section.
return productos.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
title = productos[indexPath.row].nombre
let cell = tableView.dequeueReusableCellWithIdentifier("CellDetail", forIndexPath: indexPath) as! ProductoTableViewCell
cell.selectionStyle = .None
if let url = NSURL(string: productos[indexPath.row].imagen) {
if let data = NSData(contentsOfURL: url) {
self.productoImageView.image = UIImage(data: data)
}
}
cell.nombre.text = productos[indexPath.row].nombre
cell.descripcion.text = productos[indexPath.row].descripcion
cell.modo_de_empleo.text = productos[indexPath.row].modo_de_empleo
cell.marca.text = productos[indexPath.row].marca
cell.linea.text = productos[indexPath.row].linea
cell.distribuidor.text = productos[indexPath.row].distribuidor
cell.tamano.text = productos[indexPath.row].tamano
cell.precio.text = productos[indexPath.row].precio
cell.codigo_nacional.text = productos[indexPath.row].codigo_nacional
cell.layoutIfNeeded()
return cell
}
}
Thanks in advance.

Answer 1

At first, please try to provide english code :) but anyways. I think the view what should appear is nonEncontrado.
There could be some issues but i need to see the storyboard.
The view has userInteraction not enabled. Its a property and can also be activated in the storyboard
The view is overlayed by something else. Maybe the empty tableView.
As an suggestion you could provide this fields in the tableView and just load another DataSource. Than you dont need to fight with extra views. If you provide screens from the Storyboard i could help a bit more.
Good Luck :)
