tableView.hidden breaks other elements - ios

Question

I have in my iOS app a mapView, and a UISearchBar to search locations and center the user on it. The results of my search are made by autocompletion and displayed in a tableView.
I had trouble with it, when i clicked on cancel, it displayed me all of my datas in the tableView.
So I implemented this function:
func searchBarCancelButtonClicked(searchBar: UISearchBar) {
searchTableView.hidden = true
}
But the render of that function makes this:
I don't know (and don't know how to see) if my mapView is still under the black screen.
By the way, if I delete my cancel button function, and search something, if I click on Cancel it will display something like this:
To hide my tableView again, I have to make another search, than delete it with the little cross button, then cancel.
My code, of the autocompletion search, is like that:
func initTableView() {
searchTableView.delegate = self
searchTableView.dataSource = self
searchTableView.scrollEnabled = true
searchTableView.hidden = true
}
func searchBarSearchButtonClicked() {
searchTableView.hidden = false
searchBar.resignFirstResponder()
dismissViewControllerAnimated(true, completion: nil)
searchBar(searchBar, textDidChange: searchBar.text!)
}
func searchBar(_searchBar: UISearchBar, textDidChange searchText: String) {
searchTableView.reloadData()
searchAutocompleteEntriesWithSubstring(searchText)
}
func searchAutocompleteEntriesWithSubstring(substring: String) {
searchBar.filtredDatas.removeAll(keepCapacity: false)
for curString in searchBar.datas {
let myString:NSString! = curString.title! as NSString
let substringRange :NSRange! = myString.rangeOfString(substring)
if (substringRange.location == 0) {
searchBar.filtredDatas.append(curString)
}
}
}
This is from my ViewController.swift file.
My searchBar variable is a custom class that contains an NSArray of datas and another of fileterDatas.
#IBOutlet weak var mapView: UGOMapController!
#IBOutlet var searchTableView: UITableView!
#IBOutlet weak var searchBar: UGOSearchBar!
Thanks for your help.
If you need more of my code, I can edit this post.
Edit:
Here are my UITableView functions, used for searchTableView
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return searchBar.filtredDatas.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let autoCompleteRowIdentifier = "AutoComplete"
var cell = tableView.dequeueReusableCellWithIdentifier(autoCompleteRowIdentifier) as UITableViewCell!
if cell != nil {
let index = indexPath.row as Int
if (searchBar.filtredDatas.count > 0) {
cell!.textLabel!.text = searchBar.filtredDatas[index].title
}
}
else {
cell = UITableViewCell(style: UITableViewCellStyle.Value1, reuseIdentifier: autoCompleteRowIdentifier)
}
return cell!
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
let selectedCell : UITableViewCell = tableView.cellForRowAtIndexPath(indexPath)!
searchBar.text = selectedCell.textLabel!.text
}
And my hierarchy:
And my viewController inspector:

Answer 1

You have 3 different outlets connected to the table view.
It means that when you hide the tableView, you also hide the view, because it's connected to the same Search Table View
You have to make sure that you connect your table view just to one outlet.
Edit
To be more precise:
You have to change your view controller from UITableViewController to UIViewController.
The view outlet will be connected to viewController's view property.
The tableView outlet will be removed, because in a normal UIViewController this property doesn't exist. (It's defined in UITableViewController)
SearchTableView should be connected to the searchTableView property that you define in your view controller.
