我想在解析数据库中搜索用户,但是当我在搜索栏中输入用户名时,没有任何内容被添加到uitable中。如何在uitableview上获取搜索到的用户?我在搜索后尝试将用户打印到控制台,但我没有得到任何名字。
@IBOutlet weak var searchbar: UISearchBar!
var searchActive : Bool = false
var data:[PFObject]!
var filtered:[PFObject]!
override func viewDidLoad() {
searchbar.delegate = self
search()
}
func search(searchText: String? = nil){
let query = PFQuery(className: "User")
if(searchText != nil){
query.whereKey("username", containsString: searchText)
}
query.findObjectsInBackgroundWithBlock { (results, error) -> Void in
self.data = results as? [PFObject]
self.table3.reloadData()
}
}
func tableView(tableView: UITableView, numberOfRowsInTableView: Int) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if(self.data != nil){
println(self.data.count)
return self.data.count
}
return 0
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCellWithIdentifier("cell") as? UITableViewCell
let obj = self.data[indexPath.row]
cell!.textLabel!.text = obj["text"] as? String
return cell!
}
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) {
search(searchText: searchText)
}
答案 0 :(得分:0)
试试这个:
让query = PFQuery(className:“_ User”)
或者
让query = PFUser.query()
