以编程方式实例化EditCountsTableViewCell
后,它的出口在访问时返回nil,因此我无法编辑单元格。使用Storyboard实例化时,单元格表现正常。
@IBAction func countNameChanged(sender: AnyObject) {
let textField = sender as! UITextField
let text = textField.text
let superview = textField.superview!
let cell = superview.superview as! EditCountsTableViewCell
let indexPath = self.tableView.indexPathForCell(cell)
let row = indexPath?.row
var newCell = EditCountsTableViewCell() //Instantiate Cell Programatically
println(newCell)
println(newCell.countName) //nil
if let name = newCell.countName{
name.text = text
}
if let value = newCell.countValue{
value.text = cell.countValue.text
}
tableViewContents[row!] = newCell
}
EditCountsTableViewCell
上课:
import UIKit
class EditCountsTableViewCell: UITableViewCell {
@IBOutlet weak var countName: UITextField!
@IBOutlet weak var countValue: UITextField!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}

您是否尝试过这种初始化方法?
let storyboard = UIStoryboard(name: "MyStoryboardName", bundle: nil)
let vc = storyboard.instantiateViewControllerWithIdentifier("someViewController") as! UIViewController

您希望以编程方式获取EditCountsTableViewCell变量,但您的单元格是从故事板中提取的,因此您应该从故事板中获取它。
