我的Model文件：
起初我的TimeModel
import Foundation
class TimeModel {
var hrs = ""
var min = ""
var sec = ""
var time = ""
init(hrs: String, min: String, sec: String, time: String) {
self.hrs = hrs
self.min = min
self.sec = sec
self.time = time
}
}
然后我有一个data文件：
import Foundation
class Data {
class func getDataTime() -> [TimeModel] {
var dataTime = [TimeModel]()
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,0", time: "Custom Time"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,00013", time: "1/8000"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,00016", time: "1/6400"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,0002", time: "1/5000"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,00025", time: "1/4000"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,00031", time: "1/3200"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,0004", time: "1/2500"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,0005", time: "1/2000"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,00062", time: "1/1600"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,0008", time: "1/1250"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,001", time: "1/1000"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,00125", time: "1/800"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,00156", time: "1/640"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,002", time: "1/500"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,0025", time: "1/400"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,00313", time: "1/320"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,004", time: "1/250"))
dataTime.append(TimeModel(hrs: "0", min: "0", sec: "0,005", time: "1/200"))
return dataTime
}
}
这是我的 PickerView 代码：
import UIKit
class TimeModelPicker: UIView, UIPickerViewDataSource, UIPickerViewDelegate {
var timeModelData = [TimeModel]()
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return timeModelData.count
}
func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView {
let pickerLabel = UILabel()
pickerLabel.textColor = UIColor.white
pickerLabel.text = timeModelData[row].time
pickerLabel.font = UIFont.boldSystemFont(ofSize: 25)
pickerLabel.textAlignment = NSTextAlignment.center
return pickerLabel
}
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
let defaults = UserDefaults.standard
defaults.set(row, forKey: "saveTimePicker")
}
}
最后是我的 VewController 中的代码：
import UIKit
class PickerViewTimeController: UIViewController {
@IBOutlet weak var pickerViewTime: UIPickerView!
@IBOutlet weak var pickerViewLabel: UILabel!
@IBOutlet weak var okButton: UIButton!
@IBOutlet weak var timeStd: UITextField!
@IBOutlet weak var timeMin: UITextField!
@IBOutlet weak var timeSec: UITextField!
var dataPickerViewTime: TimeModelPicker!
//unwind / ok Button
@IBAction func unwindtoCalculate(_ sender: UIStoryboardSegue){
dismiss(animated: true, completion: nil)
}
override func viewDidLoad() {
super.viewDidLoad()
dataPickerViewTime = TimeModelPicker()
dataPickerViewTime.timeModelData = Data.getDataTime()
pickerViewTime.delegate = dataPickerViewTime
pickerViewTime.dataSource = dataPickerViewTime
if let selectedRow = UserDefaults.standard.object(forKey: "saveTimePicker") as? Int {
pickerViewTime.selectRow(selectedRow, inComponent: 0, animated: true)
}
// how can i get the output from the PickerView "didSelectRow" in this textfields / label ?
pickerViewLabel.text = "time"
timeStd.text = "h"
timeMin.text = "min"
timeSec.text = "sec"
}
}
如何在文本字段和标签中time h min显示值？sec
