IOS SWIFT : 当我的 Popover 单元格之一被选中时更改我的 BarButtonItem 标题
IOS SWIFT : Change My BarButtonItem Title when one of my Popover cell is selected
抱歉 IOS Swift 中的新手。只是想问一下，当我的 Popover 单元格之一被选中时，如何更改我的 BatButtonItem 标题。即使我使用委托方法。但是我还是不行。
我的在这里运行不正常。

这是我的 LANGUAGETABLEVIEWCELL.swift
//
// LanguageTableViewCell.swift
// SwiftLoginScreen

//
import UIKit
class LanguageTableViewCell: UITableViewCell {

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
}
}
当我尝试调试这部分代码时，当我的代码 运行 时，它不会通过这段代码。为什么？
func changeName(text: String) {
self.barButtonItem.title = "\(text)" // For get barButton you should create IBOutlet for barButtonItem
print(self.barButtonItem.title)
}
请帮忙。
第 1 步：在 LanguageViewController 中制定一个您将发送数据的协议。
protocol LanguageViewControllerDelegate{
func changeName(text:String)
}
Step2:在发送中声明委托class(即HOMEVC)
class LanguageViewController: UIViewController {
var delegate:LanguageViewControllerDelegate! = nil
[...]
}
Step3:在一个class方法中使用delegate将数据发送给接收方法，接收方法可以是任何采用该协议的方法
func tableView(tableView: UITableView, didselectRowAtIndexPath indexPath: NSIndexPath) {
delegate!.changeName(arrLanguage[indexPath.row])
}
第四步：接收时采用协议class
class HomeViewController: UIViewController,LanguageViewControllerDelegate { }
第 5 步：实现委托方法（HomeViewController - 如您的问题）
func changeName(text: String) {
self.barButton.title = "\(text)" // For get barButton you should create IBOutlet for barButtonItem
}
第 6 步： 在弹出框的 BarButtonItem 的操作按钮中设置委托：
@IBAction func languageButton(sender: AnyObject) {
let storyboard : UIStoryboard = UIStoryboard(name: "Storyboard", bundle: nil)
var menuViewController: LanguageViewController = storyboard.instantiateViewControllerWithIdentifier("LanguageViewController") as! LanguageViewController
menuViewController.modalPresentationStyle = .Popover
menuViewController.preferredContentSize = CGSizeMake(50, 100)
menuViewController.delegate = self // Put this Line
let popoverMenuViewController = menuViewController.popoverPresentationController
popoverMenuViewController?.permittedArrowDirections = .Any
popoverMenuViewController?.sourceView = menuViewController.view
popoverMenuViewController?.delegate = self
popoverMenuViewController?.sourceRect = CGRect(x:240, y:35, width: 1, height: 1)
presentViewController(menuViewController, animated: true, completion: nil)
}
Yoy 应该将 tableView 委托和数据源放在 viewDidLoad() 中：-
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
tableView.tableFooterView = UIView()
}
和 tableView didSelectRow :-
func tableView(tableView: UITableView, didselectRowAtIndexPath indexPath: NSIndexPath) {
delegate!.changeName(arrLanguage[indexPath.row])
}
希望这会奏效....

这是我的 LANGUAGETABLEVIEWCELL.swift
//

class LanguageTableViewCell: UITableViewCell {

super.awakeFromNib()
// Initialization code

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

当我尝试调试这部分代码时，当我的代码 运行 时，它不会通过这段代码。为什么？
func changeName(text: String) {
self.barButtonItem.title = "\(text)" // For get barButton you should create IBOutlet for barButtonItem
print(self.barButtonItem.title)
}
请帮忙。
第 1 步：在 LanguageViewController 中制定一个您将发送数据的协议。
protocol LanguageViewControllerDelegate{
func changeName(text:String)
}
Step2:在发送中声明委托class(即HOMEVC)
class LanguageViewController: UIViewController {
var delegate:LanguageViewControllerDelegate! = nil
[...]
}
Step3:在一个class方法中使用delegate将数据发送给接收方法，接收方法可以是任何采用该协议的方法
func tableView(tableView: UITableView, didselectRowAtIndexPath indexPath: NSIndexPath) {
delegate!.changeName(arrLanguage[indexPath.row])
}
第四步：接收时采用协议class
class HomeViewController: UIViewController,LanguageViewControllerDelegate { }
第 5 步：实现委托方法（HomeViewController - 如您的问题）
func changeName(text: String) {
self.barButton.title = "\(text)" // For get barButton you should create IBOutlet for barButtonItem
}
第 6 步： 在弹出框的 BarButtonItem 的操作按钮中设置委托：
@IBAction func languageButton(sender: AnyObject) {
let storyboard : UIStoryboard = UIStoryboard(name: "Storyboard", bundle: nil)
var menuViewController: LanguageViewController = storyboard.instantiateViewControllerWithIdentifier("LanguageViewController") as! LanguageViewController
menuViewController.modalPresentationStyle = .Popover
menuViewController.preferredContentSize = CGSizeMake(50, 100)
menuViewController.delegate = self // Put this Line
let popoverMenuViewController = menuViewController.popoverPresentationController
popoverMenuViewController?.permittedArrowDirections = .Any
popoverMenuViewController?.sourceView = menuViewController.view
popoverMenuViewController?.delegate = self
popoverMenuViewController?.sourceRect = CGRect(x:240, y:35, width: 1, height: 1)
presentViewController(menuViewController, animated: true, completion: nil)
}
Yoy 应该将 tableView 委托和数据源放在 viewDidLoad() 中：-
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
tableView.tableFooterView = UIView()
}
和 tableView didSelectRow :-
func tableView(tableView: UITableView, didselectRowAtIndexPath indexPath: NSIndexPath) {
delegate!.changeName(arrLanguage[indexPath.row])
}
希望这会奏效....
