我目前正在制作一个练习快速程序,需要将CoreData结果显示在桌面上。
我构建了我的应用程序,使得故事板本身不包含任何UI元素,只包含视图(附带UIViewController
类),然后加载自定义nibs / xibs(同时还附带{{{ 1}}子类)。在这种情况下,xib包含UIView
,单独的xib包含单元格。
TableView类:
UITableView
TableView控制器:
import UIKit
protocol SkillsViewDelegate{
}
class SkillsView: UIView {
var delegate : SkillsViewDelegate!
@IBOutlet weak var skillsTable: UITableView!
}
TableCellView类:
import UIKit
import CoreData
class SkillsViewController: UIViewController, SkillsViewDelegate, UITableViewDataSource, UITableViewDelegate {
var displaySkillsView : SkillsView!
var displaySkillsCell : SkillViewCell!
let textCellIdentifier = "skillViewCell"
override func viewDidLoad() {
super.viewDidLoad()
self.displaySkillsView = UIView.loadFromNibNamed("SkillsView") as! SkillsView
self.displaySkillsView.delegate = self
self.view = self.displaySkillsView
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//MARK : -Table view delegates
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return 1
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier(textCellIdentifier, forIndexPath: indexPath)
return cell
}
}
我无法弄清楚如何将单元格xib调用到控制器中。我猜它是like this problem的东西,但区别在于那个人正在使用import UIKit
protocol SkillsViewCellDelegate{
}
class SkillViewCell: UITableViewCell {
var delegate : SkillsViewCellDelegate!
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
@IBOutlet weak var skillName: UILabel!
@IBOutlet weak var skillRank: UILabel!
}
。我也尝试添加它,但我遇到了UITableViewController
我的麻烦。
我尝试了什么:
我尝试将Multiple inheritance from classes 'UIViewController' and 'UITableViewController'
添加到最顶层,但我遇到了问题的UITableViewController
。
有什么建议吗?

您可以在SkillsViewController中注册SkillsViewCell
对象C
-(void)viewDidLoad {
[super viewDidLoad];
UINib *cellNib = [UINib nibWithNibName:@"NibName" bundle:nil];
[self.skillsTable registerNib:cellNib forCellReuseIdentifier:textCellIdentifier];
}
Swift 2
override func viewDidLoad() {
super.viewDidLoad()
let nibName = UINib(nibName: "NibName", bundle:nil)
self.skillsTable.registerNib(nibName, forCellReuseIdentifier: textCellIdentifier)
}
Swift 4
override func viewDidLoad() {
super.viewDidLoad()
let nibName = UINib(nibName: "NibName", bundle:nil)
self.skillsTable.register(nibName, forCellReuseIdentifier: textCellIdentifier)
}
然后只从UIViewController继承而不是UITableViewController
调用特定于自定义单元格的方法
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier(textCellIdentifier, forIndexPath: indexPath) as! SkillViewCell
cell.skillName.text = "Some text"
cell.skillRank.text = "Some text"
return cell
}

我认为你需要使用
func registerNib(_ nib: UINib?, forCellReuseIdentifier identifier: String)
viewDidLoad
中的
