UISearchBar with a grouped table view -- in Swift - ios

Question

Forgive me for not being able to figure this out on my own. I picked up iOS at Swift, and didn't learn much of objective-c.
I'm attempting to build in a uisearchbar that filters through a grouped table view composed of multiple arrays for it's sections. Essentially, I need to filter through an NSMutableArray built of other arrays in order to get my search results (normal array couldn't compile in 'reasonable time'). I took a look at this tutorial and it's getting at what I need, but unfortunately, I'm not the best when it comes to translating Obj-c over to swift, in this case. Any help (translation) or direction to other tutorials that will help me do this is greatly appreciated. I've been searching and searching, and tinkering all night -- but I've caved, I need some help.
Edit: still not answered

Answer 1

It is similar to objective-c code but lets start from here
After you create your view controller,table view and search bar components,
In ViewController class, you have to delegate items to ViewController like:
tableView.delegate = self
tableView.dataSource = self
searchBar.delegate = self
And then you have to implement(override) methods like
func searchBar(searchBar: UISearchBar, textDidChange searchText: String) {
filtered = data.filter({ (text) -> Bool in
let tmp: NSString = text
let range = tmp.rangeOfString(searchText, options: NSStringCompareOptions.CaseInsensitiveSearch)
return range.location != NSNotFound
})
if(filtered.count == 0){
searchActive = false;
} else {
searchActive = true;
}
self.tableView.reloadData()
}

Add these UISearchBarDelegate methods in your class and your class must confirm to this protocol using either code self.yourSearchBar.delegate = self or in storyboard.
func searchBarTextDidEndEditing(searchBar: UISearchBar) {
searchBar.resignFirstResponder()
}
func searchBarCancelButtonClicked(searchBar: UISearchBar) {
searchBar.text = ""
searchBar.resignFirstResponder()
self.searchedArrayToDisplay = self.listDataArray
}
func searchBarSearchButtonClicked(searchBar: UISearchBar) {
searchBar.resignFirstResponder()
}
func searchBar(searchBar: UISearchBar, textDidChange searchText: String) {
if searchText == "\n" {
searchBar.resignFirstResponder()
} else if searchText == "" {
self.searchedArrayToDisplay = self.listDataArray
} else {
self.filterContentForSearchText(searchText)
}
}
func filterContentForSearchText(searchText: String) {
self.searchedArrayToDisplay = self.listDataArray.filter({(eachObject: [String:AnyObject]) -> Bool in
let name = eachObject["name"] as! String
let stringMatch = name.lowercaseString.rangeOfString(searchText.lowercaseString)
let result = stringMatch != nil ? true : false
return result
})
}
Now in cell for at index path method
func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! {
let cell : UITableViewCell = UITableViewCell(style:UITableViewCellStyle.Value1, reuseIdentifier:"cell")
var object = self.searchedArrayToDisplay[indexPath.row]
}
