我只想在点击搜索栏时显示表格视图(比如instagram)。如果有人知道怎么做,任何信息都会有帮助。
这是我的相关代码:
class UserSearchController: UICollectionViewController, UICollectionViewDelegateFlowLayout,UISearchBarDelegate, UISearchDisplayDelegate {
let cellId = "cellId"
let searchBar: UISearchBar = {
let sb = UISearchBar()
sb.placeholder = "Search"
return sb
}()
fileprivate func setupNavBarAndSearchBar() {
let navBar = navigationController?.navigationBar
searchBar.delegate = self
navigationController?.navigationBar.addSubview(searchBar)
//Constraints already figured^^
}
func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) {searchBar.setShowsCancelButton(true, animated: true)}
func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
searchBar.setShowsCancelButton(true, animated: true)
}
func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
searchBar.resignFirstResponder()
searchBar.setShowsCancelButton(false, animated: true)
searchBar.text = ""
}
override func viewDidLoad() {
super.viewDidLoad()
setupNavBarAndSearchBar()
collectionView?.backgroundColor = .white
collectionView?.register(UserProfileVideoCell.self, forCellWithReuseIdentifier: cellId)
searchBar.addSubview(SearchUsersTv) **Compiles error "expected argument type UIView"**
}
以下是“SearchUsersTv”文件的内容:
class SearchUsersTv: UIView, UITableViewDelegate, UITableViewDataSource {
let cellId = "cellId"
var tableView = UITableView()
let screenHeight = UIScreen.main.bounds.height
let screenWidth = UIScreen.main.bounds.width
override init(frame: CGRect){
super.init(frame: frame)
setup()
tableView.delegate = self
tableView.dataSource = self
tableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell")
}
func setup() {
self.backgroundColor = UIColor.black
tableView = UITableView(frame: CGRect(x: 0, y: 0, width: screenWidth*0.5, height: screenHeight))
tableView.layer.backgroundColor = UIColor.black.cgColor
self.addSubview(tableView)
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 10
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: cellId, for: indexPath)
cell.backgroundColor = .magenta
return cell
}
现在上面的这个文件没有运行,因为它没有运行(它编译
尝试将此添加为第一个文件中的子视图时出错)
最佳答案
在情节提要中,首先将TableView alpha值设置为“0”。
只需在你的
func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) {searchBar.setShowsCancelButton(true, animated: true)}
这样地
tableView.alpha = 1.0
希望这能帮到我。它也解决了我的问题。
