Uitableview Swift-搜索时禁用刷新控制
在搜索过程中,我想禁用pull to refresh机制。所以我禁用了刷新控件并将其删除。但是当下拉刷新时,会调用beginRefresh方法,并且单元格会像刷新一样持续关闭2秒钟Uitableview Swift-搜索时禁用刷新控制,uitableview,swift,uirefreshcontrol,Uitableview,Swift,Uirefreshcontrol,在搜索过程中,我想禁用pull to refresh机制。所以我禁用了刷新控件并将其删除。但是当下拉刷新时,会调用beginRefresh方法,并且单元格会像刷新一样持续关闭2秒钟 func searchBarShouldBeginEditing(searchBar: UISearchBar) -> Bool { resultSearchController.searchBar.selectedScopeButtonIndex = 0 refreshControl!.ena
func searchBarShouldBeginEditing(searchBar: UISearchBar) -> Bool {
resultSearchController.searchBar.selectedScopeButtonIndex = 0
refreshControl!.enabled = false
refreshControl?.removeFromSuperview()
return true
}
如果要在UITableView顶部创建或删除刷新控件,请使用这两个函数
func createRefreshControl() {
// Create RefreshControl and add to tableView
self.refreshControl = UIRefreshControl()
self.refreshControl!.attributedTitle = NSAttributedString(string: " ↓ Refresh ↓ ")
self.refreshControl!.addTarget(self, action: "refresh:", forControlEvents: UIControlEvents.ValueChanged)
}
func deleteRefreshControl() {
// delete RefreshControl
self.refreshControl = nil
}
搜索时,检查refreshControl是否具有superView,并在搜索结束后从superView中删除。再次添加它,条件如下所示:
if self.refreshControl.isDescendant(of: self.tblView) {
self.refreshControl.removeFromSuperview()
}
尝试使用此代码,它对我有效:
var refresh : UIRefreshControl!
func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) {
print("START TABBAR")
if #available(iOS 10.0, *) {
if let refresh = self.tableView.refreshControl {
if refresh.isDescendant(of: self.tableView) {
self.tableView.refreshControl?.removeFromSuperview()
}
}
} else {
for subview in self.tableView.subviews {
if let refresh = subview as? UIRefreshControl {
refresh.removeFromSuperview()
}
}
}
}
func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
print("FINISH SEARCH")
self.refresh = UIRefreshControl()
self.refresh.attributedTitle = NSAttributedString(string: "Update data")
self.refresh.addTarget(self, action: #selector(updateFunction), for: .valueChanged)
if #available(iOS 10.0, *) {
self.tableView.refreshControl = self.refresh
} else {
self.tableView.addSubview(self.refresh)
}
}
@objc func updateFunction() {
//Your function to update the tableView
}
要调用这些函数,您需要实现UISearchBarDelegate
它也适用于iOS9
