I am see below error at the line "tableView.delegate = self" - EXC_BAD_INSTRUCTION (code=EXC_1386_INVOP, subside0x0). Unable to figure out what is causing the issue. I have a simple Table View with Search Bar Storyboard.
import UIKit
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate, UISearchBarDelegate{
@IBOutlet weak var searchBar: UISearchBar!
@IBOutlet weak var tableView: UITableView!
var searchActive : Bool = false
var data = ["San Francisco","New York","San Jose","Chicago","Los Angeles","Austin","Seattle"]
var filtered:[String] = []
override func viewDidLoad() {
super.viewDidLoad()
/* Setup delegates */
tableView.delegate = self **//Error thrown here**
tableView.dataSource = self
searchBar.delegate = self
}
func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) {
searchActive = true;
}
func searchBarTextDidEndEditing(_ searchBar: UISearchBar) {
searchActive = false;
}
func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
searchActive = false;
}
func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
searchActive = false;
}
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
filtered = data.filter({ (text) -> Bool in
let tmp: NSString = text as NSString
let range = tmp.range(of: searchText, options: NSString.CompareOptions.caseInsensitive)
return range.location != NSNotFound
})
if(filtered.count == 0){
searchActive = false;
} else {
searchActive = true;
}
self.tableView.reloadData()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if(searchActive) {
return filtered.count
}
return data.count;
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell")! as UITableViewCell;
if(searchActive){
cell.textLabel?.text = filtered[indexPath.row]
} else {
cell.textLabel?.text = data[indexPath.row];
}
return cell;
}
}
