使用swift在tableviewcell内创建tableview [英] create tableview inside tableviewcell using swift

问题描述

好吧，我用xib文件创建tableview并在其中创建tableview单元

well i create tableview and inside of it tableview cell with xib file

现在我想在xib文件中创建tableview，主要问题是你不能在其中创建单元格来定义这个单元格的标识符

now i want create tableview inside xib file , the main problem is that u can't create cell inside of it to define the identifier for this cell

我一直收到这个错误

'无法将带有标识符 AutoCompleteRowIdentifier 的单元格出列 -必须为标识符注册一个笔尖或一个类，或者连接一个故事板中的原型单元格'

'unable to dequeue a cell with identifier AutoCompleteRowIdentifier - must register a nib or a class for the identifier or connect a prototype cell in a storyboard'

这是我的代码

import UIKit

class TableViewCell2: UITableViewCell, UITableViewDelegate, UITableViewDataSource, UITextFieldDelegate {

@IBOutlet weak var textField: UITextField!

@IBOutlet weak var autocompleteTableView: UITableView!

var pastUrls = ["Men", "Women", "Cats", "Dogs", "Children"]
var autocompleteUrls = [String]()


func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool
{
    autocompleteTableView.hidden = false
    let substring = (textField.text! as NSString).stringByReplacingCharactersInRange(range, withString: string)
    
    searchAutocompleteEntriesWithSubstring(substring)
    return true     // not sure about this - could be false
}

func searchAutocompleteEntriesWithSubstring(substring: String)
{
    autocompleteUrls.removeAll(keepCapacity: false)
    
    for curString in pastUrls
    {
        var myString:NSString! = curString as NSString
        
        var substringRange :NSRange! = myString.rangeOfString(substring)
        
        if (substringRange.location  == 0)
        {
            autocompleteUrls.append(curString)
        }
    }
    
    autocompleteTableView.reloadData()
}



func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return autocompleteUrls.count
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    
    let autoCompleteRowIdentifier = "AutoCompleteRowIdentifier"
    let cell : UITableViewCell = tableView.dequeueReusableCellWithIdentifier(autoCompleteRowIdentifier, forIndexPath: indexPath) as UITableViewCell
    let index = indexPath.row as Int
    
    cell.textLabel!.text = autocompleteUrls[index]
    return cell
}

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    let selectedCell : UITableViewCell = tableView.cellForRowAtIndexPath(indexPath)!
    textField.text = selectedCell.textLabel!.text
}

override func awakeFromNib() {
    super.awakeFromNib()
    textField.delegate = self
    autocompleteTableView.delegate = self
    autocompleteTableView.dataSource = self
    autocompleteTableView.scrollEnabled = true
    autocompleteTableView.hidden = true
}

override func setSelected(selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)
    
    // Configure the view for the selected state
}}

如您所知，您无法在 xib 文件中定义标识符

as you know you can't define identifier inside xib file

谢谢

推荐答案

您需要先使用 autocompleteTableView 注册单元格，然后才能将其出列.像这样修改你的代码:

You need to register a cell with autocompleteTableView before you can dequeue it. Modify your code like this:

override func awakeFromNib() {
    super.awakeFromNib()
    textField.delegate = self
    autocompleteTableView.delegate = self
    autocompleteTableView.dataSource = self
    autocompleteTableView.scrollEnabled = true
    autocompleteTableView.hidden = true

    // Register cell
    autocompleteTableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "AutoCompleteRowIdentifier")
}
