[英]iOS8 Cannot hide cancel button on search bar in UISearchController
[英]Hide Cancel Button on UISearchController swift 2.0
使用seachController.searchBar.setShowsCancelButton(false,animated:false)似乎仍然不能做到这一点。
尝试将UISearchBarDelegate添加到您的控制器,并将searchBar的委托分配给self。 然后,您可以使用searchBarShouldBeginEditing
编辑其可见性。
import UIKit
class TableViewController: UITableViewController, UISearchBarDelegate {
var searchController: UISearchController!
let menuItems: [String] = ["Row 1", "Row 2", "Row 3"]
override func viewDidLoad() {
super.viewDidLoad()
let searchResultsController = storyboard!.instantiateViewControllerWithIdentifier("SearchResultsViewControllerStoryboardIdentifier") as! SearchResultsTableViewController
searchController = UISearchController(searchResultsController: searchResultsController)
searchController.hidesNavigationBarDuringPresentation = false
searchController.searchBar.delegate = self
}
@IBAction func searchButtonPressed(sender: UIBarButtonItem) {
presentViewController(searchController, animated: true, completion: nil)
}
func searchBarShouldBeginEditing(searchBar: UISearchBar) -> Bool {
searchController.searchBar.setShowsCancelButton(false, animated: true)
return true
}
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return menuItems.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath)
cell.textLabel?.text = self.menuItems[indexPath.row]
return cell
}
}
