我有两个视图控制器与tabBar连接。在第一个选项卡中，我看到所有按钮都添加了修复和删除修复。在我的私有项目的第一步中，我有修复时间的静态值。现在在我的第二步中，我想要通过第二次点击来改变一个人需要修复的时间，但是当我在第二个VieController中编辑时间后返回时，结构的值没有改变。
ViewController.swift
class ViewController: UIViewController {
@IBOutlet weak var AddBrepair: UIButton!
@IBOutlet weak var AddOrepair: UIButton!
@IBOutlet weak var AddDrepair: UIButton!
@IBOutlet weak var GeniusNumber: UISegmentedControl!
@IBOutlet weak var AddBCrepair: UIButton!
@IBOutlet weak var CheckOutOrepair: UIButton!
@IBOutlet weak var CheckOutBrepair: UIButton!
@IBOutlet weak var CheckOutBCrepair: UIButton!
@IBOutlet weak var CheckOutDrepair: UIButton!
@IBOutlet weak var DisplayLeftNumber: UILabel!
@IBOutlet weak var RFPTime: UILabel!
@IBOutlet weak var CurrentTimerepair: UILabel!
let repairTime=RepairTime()
override func viewDidLoad() {
super.viewDidLoad()
//RFPTime.text = repairTime.ReadyForPickup()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
//print(repairTime.getNumberOfRepairGenius())
}
@IBAction func Controller(sender: AnyObject) {
repairTime.NumberOfRepairGenius(GeniusNumber.selectedSegmentIndex+1)
CurrentTimerepair.text = String(format:"%.1f", repairTime.TimeOfRepair())
RFPTime.text = String(repairTime.ReadyForPickup())
}
@IBAction func AddBr(sender: AnyObject) {
repairTime.NumberOfBatteryRepair(repairTime.getNumberOfBatteryRepair()+1)
CurrentTimerepair.text = String(format:"%.1f", repairTime.TimeOfRepair())
RFPTime.text = String(repairTime.ReadyForPickup())
}
@IBAction func AddOr(sender: AnyObject) {
repairTime.NumberOfOtherRepair(repairTime.getNumberOfOtherRepair()+1)
CurrentTimerepair.text = String(format:"%.1f", repairTime.TimeOfRepair())
RFPTime.text = String(repairTime.ReadyForPickup())
}
@IBAction func AddBCr(sender: AnyObject) {
repairTime.NumberOfBackCoverRepair(repairTime.getNumberOfBackCoverRepair()+1)
CurrentTimerepair.text = String(format:"%.1f", repairTime.TimeOfRepair())
RFPTime.text = String(repairTime.ReadyForPickup())
}
@IBAction func AddDr(sender: AnyObject) {
repairTime.NumberOfDisplayRepair(repairTime.getNumberOfDisplayRepair()+1)
CurrentTimerepair.text = String(format:"%.1f", repairTime.TimeOfRepair())
RFPTime.text = String(repairTime.ReadyForPickup())
//print("view controler")
//print(
}
@IBAction func DeleteBr(sender: AnyObject) {
if(repairTime.getNumberOfBatteryRepair() != 0){
repairTime.NumberOfBatteryRepair(repairTime.getNumberOfBatteryRepair()-1)
CurrentTimerepair.text = String(format:"%.1f", repairTime.TimeOfRepair())
RFPTime.text = String(repairTime.ReadyForPickup())
}
}
@IBAction func DeleteOr(sender: AnyObject) {
if(repairTime.getNumberOfOtherRepair() != 0){
repairTime.NumberOfOtherRepair(repairTime.getNumberOfOtherRepair()-1)
CurrentTimerepair.text = String(format:"%.1f", repairTime.TimeOfRepair())
RFPTime.text = String(repairTime.ReadyForPickup())
}
}
@IBAction func DeleteBCr(sender: AnyObject) {
if(repairTime.getNumberOfBackCoverRepair() != 0){
repairTime.NumberOfBackCoverRepair(repairTime.getNumberOfBackCoverRepair()-1)
CurrentTimerepair.text = String(format:"%.1f", repairTime.TimeOfRepair())
RFPTime.text = String(repairTime.ReadyForPickup())
}
}
@IBAction func DeleteDr(sender: AnyObject) {
if(repairTime.getNumberOfDisplayRepair() != 0){
repairTime.NumberOfDisplayRepair(repairTime.getNumberOfDisplayRepair()-1)
CurrentTimerepair.text = String(format:"%.1f", repairTime.TimeOfRepair())
RFPTime.text = String(repairTime.ReadyForPickup())
}
}
@IBAction func ShowQueuePop(sender: AnyObject) {
let out="Display Repair: \(repairTime.getNumberOfDisplayRepair()) \n Other Repair: \(repairTime.getNumberOfOtherRepair()) \n Battery Repair: \(repairTime.getNumberOfBatteryRepair()) \n Back Cover Repair: \(repairTime.getNumberOfBackCoverRepair())"
let alertController = UIAlertController(title: "Current repair Queue", message: out
, preferredStyle: UIAlertControllerStyle.Alert)
alertController.addAction(UIAlertAction(title: "Dismiss", style: UIAlertActionStyle.Default,handler: nil))
self.presentViewController(alertController, animated: true, completion: nil)
}
class RepairTime {
var optiontime = OptionTime()
var RepairGenius: Int = 1
var DisplayRepair: Int = 0
var OtherRepair: Int = 0
var BackCoverRepair: Int = 0
var BatteryRepair: Int = 0
func TimeOfRepair()->Double{
var repairtimezwei: Double
repairtimezwei=0.0
var repairzeit: Int
repairzeit=0
repairzeit=(BatteryRepair*optiontime.BatteryTime)+(BackCoverRepair*optiontime.BCTime)+(DisplayRepair*optiontime.DisplayTime)+(OtherRepair*optiontime.OtherTime)
//print(DisplayRepair)
repairtimezwei = (Double(repairzeit)/Double(RepairGenius))+15.0
return repairtimezwei
}
所以这是我的第二个viewController：
class ViewController2: UIViewController,UITextFieldDelegate {
var optiontime = OptionTime()
@IBOutlet weak var DisplayTime: UITextField!
@IBOutlet weak var BatteryTime: UITextField!
@IBOutlet weak var BackCoverTime: UITextField!
@IBOutlet weak var OtherTime: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
//RFPTime.text = repairTime.ReadyForPickup()
// set TextField with Values of struct optionTime from class RepairTime
DisplayTime.text=String(optiontime.DisplayTime)
BatteryTime.text=String(optiontime.BatteryTime)
BackCoverTime.text=String(optiontime.BCTime)
OtherTime.text=String(optiontime.OtherTime)
//set KeybardType for Textinputs
self.DisplayTime.keyboardType = UIKeyboardType.NumbersAndPunctuation
self.BatteryTime.keyboardType = UIKeyboardType.NumbersAndPunctuation
self.BackCoverTime.keyboardType = UIKeyboardType.NumbersAndPunctuation
self.OtherTime.keyboardType = UIKeyboardType.NumbersAndPunctuation
self.DisplayTime.delegate = self
self.BatteryTime.delegate = self
self.BackCoverTime.delegate = self
self.OtherTime.delegate = self
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
func textFieldShouldReturn(textField: UITextField) -> Bool {
self.view.endEditing(true)
return false
}
@IBAction func TimeChangeDisplay(sender: AnyObject) {
optiontime.DisplayTime = Int(DisplayTime.text!)!
print("vie controler 2")
print(optiontime.DisplayTime)
}
@IBAction func TimeChangeBattery(sender: AnyObject) {
optiontime.BatteryTime = Int(BatteryTime.text!)!
}
@IBAction func TimeChangeBC(sender: AnyObject) {
optiontime.BCTime = Int(BackCoverTime.text!)!
}
@IBAction func TimeChangeOther(sender: AnyObject) {
optiontime.OtherTime = Int(OtherTime.text!)!
}
}
我的问题是在文本字段中完成编辑后结构的值没有改变。
