uitableview - Swift - 搜索时禁用 refreshControl

Question

在搜索过程中，我想禁用下拉刷新机制。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，单元格会保持下拉状态 2 秒，就像刷新一样。

func searchBarShouldBeginEditing(searchBar: UISearchBar) -> Bool {
    resultSearchController.searchBar.selectedScopeButtonIndex = 0
    refreshControl!.enabled = false
    refreshControl?.removeFromSuperview()
    return true
}

Answer 1

如果要在 UITableView 的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
}
