Create UISearchBar with UITableView in swift language ( iOS8 ).
In this tutorials we are going to learn how to work UISearchBar with UITableView in swift language .
UISearchBar Class implements a simple a text field for searches . UISearchBar object does not perform direct we need to user UISearchBarDelegate for this and implement the action when text entered and button clicked.
First Need to create UITableView in swift : - How to create / make a simple tableview in iOS8 and swift
Now need to implement UISearchBar in this
Create global objects : -
@IBOutlet var tableView:UITableView! // This is for your tableview@IBOutlet var searchBarObj:UISearchBar! // It's for your search bar objectvar is_searching:Bool! // It's flag for searching
var dataArray:NSMutableArray! // Its data array for UITableviewvar searchingDataArray:NSMutableArray! // Its data searching array that need for search result show
Add Delegate of UITableView and UISearchbar
class ViewController: UIViewController ,UITableViewDelegate, UITableViewDataSource, UISearchBarDelegate
Now initialise all array and search flag
override func viewDidLoad() {super.viewDidLoad()// Do any additional setup after loading the view, typically from a nib.is_searching = falsedataArray = ["Apple", "Samsung", "iPHone", "iPad", "Macbook", "iMac" , "Mac Mini"]searchingDataArray = []self.tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "cell")}
Now we need to minor change in UITableViewDataSource functions
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int{if is_searching == true{return searchingDataArray.count}else{return dataArray.count //Currently Giving default Value}}func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{var cell:UITableViewCell = tableView.dequeueReusableCellWithIdentifier("cell") as UITableViewCellif is_searching == true{cell.textLabel.text = searchingDataArray[indexPath.row] as NSString}else{cell.textLabel.text = dataArray[indexPath.row] as NSString}return cell;}
Hows show in simulator now : -
Now need to implement UISearchBar Delegate function
func searchBar(searchBar: UISearchBar, textDidChange searchText: String){
if searchBar.text.isEmpty{
is_searching = false
tableView.reloadData()
} else {
println(" search text %@ ",searchBar.text as NSString)
is_searching = true
searchingDataArray.removeAllObjects()
for var index = 0; index < dataArray.count; index++
{
var currentString = dataArray.objectAtIndex(index) as String
if currentString.lowercaseString.rangeOfString(searchText.lowercaseString) != nil {
searchingDataArray.addObject(currentString)
}
}
tableView.reloadData()
}
}
After searching we can result showing according to our search
Using this delegate function we can search text using UISearchBar in UITableView
