我是这方面的初学者......说过我在我的应用程序中遇到了一个问题，我已经停滞不前，不知道接下来该做什么或修复什么。所以任何答案都将不胜感激！
所以在我的Home View Controller中，我有四个按钮，有四个不同的类别。 这些类别中的每一个都有自己的问题列表，但它们有一个共同的“一般问题”列表。一般问题列表有自己的视图控制器。 当您单击四个按钮中的任何一个时，它将进入“常规问题”视图。在这个视图的底部，我有一个“下一步”按钮。
目标：根据最初在主视图控制器中按下的内容，配置“下一步”按钮以继续进入类别的问题列表之一。
我通过视图控制器中的插座和操作连接按钮。 但是，当我控制+拖动到视图控制器时，“下一步”按钮将无法连接。我不确定我需要把代码放在哪里......
我认为Next按钮的代码可能需要某种条件语句，但由于它不能连接我甚至无法达到那么远。
帮助！
（这就是我所拥有的）示例代码： 导入UIKit 导入AddressBookUI 导入地址簿 进口基金会 导入CoreData 导入CoreGraphics 导入EventKit 导入EventKitUI 导入CoreFoundation
类ViewController：UIViewController {
@IBOutlet var ColorButton: UIButton!
@IBOutlet var StyleButton: UIButton!
@IBOutlet var CutButton: UIButton!
@IBOutlet var MakeupButton: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
var eventstore: EKEventStore!
var event: EKEvent!
weak var editViewDelegate: EKEventEditViewDelegate!
@IBAction func ColorButtonPressed(sender: UIButton) {
}
@IBAction func StyleButtonPressed(sender: UIButton) {
}
@IBAction func HaircutButtonPressed(sender: UIButton) {
}
@IBAction func MakeupButtonPressed(sender: UIButton) {
}
}

为简洁起见，下面是针对2个控制器（而不是4个）的代码所示的建议方法。使用适当的命名segue到来自公共处理控制器的每个“下一个处理”控制器并建立一个链。以下是项目文件的链接：Project file
import UIKit
class ViewController: UIViewController {
var nextVcId = 0 // defines the button that is pressed
@IBAction func unwindFromOtherControllers(segue: UIStoryboardSegue) {
// In case you want to get back to the main VC
}
@IBAction func btn2Action(sender: UIButton) {
nextVcId = 0
self.performSegueWithIdentifier("commonSegue", sender: sender)
}
@IBAction func btn1Action(sender: UIButton) {
nextVcId = 1
self.performSegueWithIdentifier("commonSegue", sender: sender)
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
let vc = segue.destinationViewController as! CommonViewController
vc.nextControllerId = nextVcId
}
}
import UIKit
class CommonViewController: UIViewController {
var nextControllerId = 0
@IBOutlet weak var StatusLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
self.StatusLabel.text = "Common"
commonProcessing()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func commonProcessing() {
// do your common processing
if nextControllerId == 0 {
performSegueWithIdentifier("next1Segue", sender: self)
} else {
performSegueWithIdentifier("next2Segue", sender: self)
}
}
}
import UIKit
class Next1ViewController: UIViewController {
@IBOutlet weak var statusLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
self.statusLabel.text = "Next1"
next1Processing()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func next1Processing() {
println("Next 1 Processing")
}
}
import UIKit
class Next2ViewController: UIViewController {
@IBOutlet weak var statusLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
statusLabel.text = "Next 2"
next2Processing()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func next2Processing() {
println("Next 2 Processing")
}
}
