我正在尝试搜索tableview中显示的数组,并且我正在关注this教程,但是当我尝试调用reloadData()方法时,我得到对成员'tableView的不明确引用( _:didSelectRowAt:)'
知道我缺少什么吗?
提前感谢任何提示。 这是我的ListController.swift代码:
import UIKit
var arrayIndex = 0
class ListController: UIViewController, UITableViewDataSource, UITableViewDelegate, UISearchBarDelegate {
let data = ["New York, NY", "Los Angeles, CA", "Chicago, IL", "Houston, TX",
"Philadelphia, PA", "Phoenix, AZ", "San Diego, CA", "San Antonio, TX",
"Dallas, TX", "Detroit, MI", "San Jose, CA", "Indianapolis, IN",
"Jacksonville, FL", "San Francisco, CA", "Columbus, OH", "Austin, TX",
"Memphis, TN", "Baltimore, MD", "Charlotte, ND", "Fort Worth, TX"]
var filteredData: [String]!
@IBOutlet var searchBarOutlet: UISearchBar!
//Table Delegate
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
arrayIndex = indexPath.row
performSegue(withIdentifier: "segue", sender: self)
}
// Table Data Source
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return filteredData.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// Cell Data Source
let cell = tableView.dequeueReusableCell(withIdentifier: "TableCell", for: indexPath) as UITableViewCell
cell.textLabel?.text = filteredData[indexPath.row]
// Cell Visual Formatting
cell.backgroundColor = UIColor(red:0.05, green:0.05, blue:0.07, alpha:0)
cell.textLabel?.textColor = UIColor.white
cell.textLabel?.font = UIFont(name: "Raleway", size: 18)
cell.accessoryType = UITableViewCellAccessoryType.disclosureIndicator
return cell
}
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
filteredData = searchText.isEmpty ? data : data.filter { (item: String) -> Bool in
return item.range(of: searchText, options: .caseInsensitive, range: nil, locale: nil) != nil
}
let tableView = UITableView()
self.tableView.reloadData()
}
override func viewDidLoad() {
super.viewDidLoad()
self.title = "\(titles.count) Definitions"
filteredData = data
}
}
答案 0 :(得分:2)
您遗失了@IBOutlet
的{{1}}。因此,当您引用tableView
时,Swift认为您正在讨论以self.tableView
开头的方法之一。
所以,在tableView
中删除这一行:
searchBar(_:textDidChange:)
并为let tableView = UITableView()
添加一个插座并连接它:
tableView
