我找不到任何的方式來增加switch button
在我的tableview我怎麼能添加UISwitch到UITableView的
我有一個搜索欄,它完美的作品,
,現在我想添加一個切換按鈕啓用「和」「或」過濾器在我的搜索。
import Foundation
import UIKit
class TableViewController: UITableViewController, UISearchResultsUpdating {
var appDel: AppDelegate!
// var customTabBarItem:UITabBarItem = UITabBarItem(title: nil, image: UIImage(named: "my.png")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal), selectedImage: UIImage(named: "my.png"))
var filteredTableData = [String]()
var resultSearchController = UISearchController()
override func viewDidLoad() {
self.edgesForExtendedLayout = UIRectEdge.None
UIApplication.sharedApplication().statusBarHidden = true
appDel = UIApplication.sharedApplication().delegate as? AppDelegate
// tabBarItem = customTabBarItem
self.resultSearchController = ({
let controller = UISearchController(searchResultsController: nil)
controller.searchResultsUpdater = self
controller.dimsBackgroundDuringPresentation = false
controller.searchBar.sizeToFit()
self.tableView.tableHeaderView = controller.searchBar
return controller
})()
// Reload the table
self.tableView.reloadData()
print("TableView called!!")
}
func updateSearchResultsForSearchController(searchController: UISearchController)
{
//refer to http://www.ioscreator.com/tutorials/add-search-table-view-tutorial-ios8-swift
filteredTableData.removeAll(keepCapacity: false)
let searchPredicate = NSPredicate(format: "SELF CONTAINS[c] %@", searchController.searchBar.text!)
let array = ((appDel.dataFetcher?.appTitles)! as NSArray).filteredArrayUsingPredicate(searchPredicate)
filteredTableData = array as! [String]
self.tableView.reloadData()
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if (self.resultSearchController.active) {
return self.filteredTableData.count
}
else if appDel.dataFetcher?.appTitles == nil {
return 0
}else{
return (appDel.dataFetcher?.appTitles?.count)!
}
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("appCell", forIndexPath: indexPath)
let currentItem: String = (appDel.dataFetcher?.appTitles?[indexPath.row])!
if (self.resultSearchController.active) {
cell.textLabel?.text = filteredTableData[indexPath.row]
return cell
}
else {
cell.textLabel?.text = currentItem
cell.detailTextLabel?.text = String(indexPath.row)
return cell
}
}
}
不建議在搜索欄之下添加開關,就像你想要的那樣。從那裏添加切換到導航欄和控制過濾器的tableview。否則,如果你真的想,那麼在表頭的標題視圖中添加開關。 – NightFury
