In tableViewCell I have userNameLbl with name, userClgLbl with number. I want to search and show data in tableView either name search or number search.
If user search name - based on name I can show data in tableView.
If user search number - based on number I can show data in tableView.
But how to work with both name and number for single search bar. Actually here my data is dynamic from server and number is not phone number.
UISearchBarDelegate added to my class
let searchBar = UISearchBar()
var filteredData: [Any]!
@IBOutlet weak var listTblView: UITableView!
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return filteredData.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// create a new cell if needed or reuse an old one
let cell = tableView.dequeueReusableCell(withIdentifier: "cell") as! TableViewCell
cell.userNameLbl.text = filteredData[indexPath.row] as? String
cell.userClgLbl.text = clg_uniq[indexPath.row] as? String
return cell
}
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
let strArr:[String] = clg_uniq as! [String]
filteredData = searchText.isEmpty ? clg_uniq : strArr.filter({(dataString: String) -> Bool in
// If dataItem matches the searchText, return true to include it
return dataString.range(of: searchText, options: .caseInsensitive) != nil
})
DispatchQueue.main.async {
self.listTblView.reloadData()
}
if searchText == "" {
DispatchQueue.main.async {
searchBar.resignFirstResponder()
}
}
}
//Added these lines after json parsing
self.filteredData = self.clg_uniq
self.listTblView.reloadData()
My example JSON data is
{"log" = (
{
Name = "Name1";
"clg_uniq" = 5c640e7b86e35;
},
{
Name = "Name2";
"clg_uniq" = <null>;
},
{
Name = <null>;
"clg_uniq" = 5c647af5d5c4d;
},
{
Name = "Name4";
"clg_uniq" = 5c647a0427253;
},
{
Name = <null>;
"clg_uniq" = <null>;
},
{
Name = "Name6";
"clg_uniq" = $cuniq";
},
)
}
Add following variables -
var logArray = [Dictionary<String, Any>]() // For all result
var searchedLogArray = [Dictionary<String, Any>]() // For filtered result
var searchActive = false // whenever user search anything
Replace UISearchBarDelegate -
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
searchActive = searchText.count > 0 ? true : false
let namePredicate = NSPredicate(format: "Name CONTAINS[c] %@", searchText)
let clgUniqPredicate = NSPredicate(format: "clg_uniq CONTAINS[c] %@", searchText)
let compoundPredicate = NSCompoundPredicate.init(orPredicateWithSubpredicates: [namePredicate, clgUniqPredicate])
searchedLogArray = logArray.filter({
return compoundPredicate.evaluate(with: $0)
})
listTblView.reloadData()
}
Replace UITableViewDataSource -
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return searchActive ? searchedLogArray.count : logArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// create a new cell if needed or reuse an old one
let cell = tableView.dequeueReusableCell(withIdentifier: "cell") as! TableViewCell
let logDict = searchActive ? searchedLogArray[indexPath.row] : logArray[indexPath.row]
// Name
if let name = log["Name"] as? String{
cell.userNameLbl.text = name
}else{
cell.userNameLbl.text = ""
}
// clg_uniq
if let clgUniq = log["clg_uniq"] as? String {
cell.userClgLbl.text = clgUniq
}else{
cell.userClgLbl.text = ""
}
return cell
}
I hope you are persing response as Dictionary<String, Any>
Let me know if you are still having any issue.
