我想在我的app中使用搜索欄。我正在嘗試使用它，但例外即將到來。我有一個名爲成員[[String:Anyobject]]的字典數組，並從中取出名稱並將其存儲到字符串類型的數組數據中，但它不起作用。ios swift中的搜索欄
這裏是我的代碼：
import UIKit
class hcbaViewController: UIViewController,UITableViewDataSource,UITableViewDelegate,UISearchBarDelegate {
@IBOutlet var searchbar: UISearchBar!
@IBOutlet var tableview: UITableView!
var member = [[String:AnyObject]]()
var members = [String:AnyObject]()
var searchActive = true
var filtered:[String] = []
var data: [String] = []
override func viewDidLoad() {
super.viewDidLoad()
print(data)
print("________-----------________----------")
print(member)
// Do any additional setup after loading the view.
}
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()
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return "MemberDirectory"
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return member.count
if(searchActive){
return filtered.count
}
else{
return data.count
}
// return member.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell: UITableViewCell = tableView.dequeueReusableCell(withIdentifier: "cell",for: indexPath)
var display = member[indexPath.row]
cell.textLabel?.text = display["Name"] as! String?
cell.detailTextLabel?.text = display["email"] as? String
let n = display["Name"] as! String
data.append(n)
return cell
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
let vc = segue.destination as! hcbadetailViewController
vc.kk = members
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
members = member[indexPath.row]
self.performSegue(withIdentifier: "bye", sender: nil)
}
