如何在自定义视图中嵌入UITableView [英] How to embed a UITableView in a custom view
问题描述
我想创建一个具有UITableView作为子视图的自定义视图。
I want to create a custom view that has a UITableView as a subview.
自定义视图以编程方式创建表视图。但是,对于外部世界(即ViewController),自定义视图本身似乎是一个表视图。
The custom view creates the table view programmatically. To the outside world (i.e., the ViewController), though, the custom view itself would appear to be a table view.
import UIKit
class CustomTableView: UIView {
// Do I make outlets?
//@IBOutlet var dataSource: UITableViewDataSource?
//@IBOutlet var delegate: UITableViewDelegate?
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
override init(frame: CGRect){
super.init(frame: frame)
}
override func awakeFromNib() {
super.awakeFromNib()
}
override func layoutSubviews() {
super.layoutSubviews()
var tableView: UITableView!
tableView = UITableView(frame: self.bounds)
// I'm not sure how to set the delegate and dataSource
// tableView.dataSource = ???
// tableView.delegate = ???
self.addSubview(tableView)
}
}
以编程方式创建UITableView并将其作为子视图添加到自定义视图父级后,我不知道如何使自定义视图像表视图一样工作。也就是说,我不知道如何为 delegate
和 dataSource获取自定义视图以在View Controller和表视图之间进行通信。
。
After creating the UITableView programmatically and adding it as a subview to the custom view parent, I can't figure out how to get the custom view to act like it is the table view. That is, I don't know how to get the custom view to do the communication between the View Controller and the table view for the delegate
and dataSource

这些文章看起来不错,但是我有点迷茫。
These articles seemed good, but I got a little lost.
如何使自定义视图的行为像自己的表子视图是否涉及委托和数据源?
How do I make the custom view act like it's own table subview with regard to delegate and data source?
推荐答案
解决方案是使 tableView
自定义类的属性(如@BaseZen建议)。然后在自定义类中提供属性和方法,以模仿并传递 tableView
所需的属性和方法。
The solution is to make the tableView
a property of the custom class (as @BaseZen suggested). Then provide properties and methods in the custom class to mimic and pass along the properties and methods needed from tableView
.
import UIKit
@IBDesignable class UICustomTableView: UIView {
private var myTableView: UITableView
required init(coder aDecoder: NSCoder) {
myTableView = UITableView()
super.init(coder: aDecoder)
}
override init(frame: CGRect){
myTableView = UITableView()
super.init(frame: frame)
}
override func awakeFromNib() {
super.awakeFromNib()
}
// TODO: @IBOutlet still can't be set in IB
@IBOutlet weak var delegate: UITableViewDelegate? {
get {
return myTableView.delegate
}
set {
myTableView.delegate = newValue
}
}
// TODO: @IBOutlet still can't be set in IB
@IBOutlet weak var dataSource: UITableViewDataSource? {
get {
return myTableView.dataSource
}
set {
myTableView.dataSource = newValue
}
}
func registerClass(cellClass: AnyClass?, forCellReuseIdentifier identifier: String) {
myTableView.registerClass(cellClass, forCellReuseIdentifier: identifier)
}
func dequeueReusableCellWithIdentifier(identifier: String) -> UITableViewCell? {
return myTableView.dequeueReusableCellWithIdentifier(identifier)
}
override func layoutSubviews() {
super.layoutSubviews()
// ...
// setup UITableView
myTableView.frame = self.bounds
self.addSubview(myTableView)
// ...
}
}
然后可以像普通的 UITableView
:
import UIKit
class TableViewDemoVC: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet weak var customTableView: UICustomTableView!
var items: [String] = ["One", "Two", "Three"]
override func viewDidLoad() {
super.viewDidLoad()
// setup the table view from the IB reference
customTableView.delegate = self
customTableView.dataSource = self
customTableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "cell")
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell: UITableViewCell = self.customTableView.dequeueReusableCellWithIdentifier("cell") as UITableViewCell!
cell.textLabel?.text = self.items[indexPath.row]
return cell
}
// ...
}
