防止偷懶日記Day9
接下來想要實做的就是把打席結果弄成選項給使用者做決定
目前想到的是使用UIPickerView, 或者是用ActionSheet
想了想用ActionSheet好像需要用很多層
所以今天先來試試UIPickerView
今天的成果大概長這樣
那就從製作UIPicerㄐView下手
先新增一個RecordPickerController.swift的檔案到Controller的Group內

| import UIKit
class RecordPickerController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource {
let recordtypeArray = ["H", "BB", "E", "K", "SC"]
var recordPickerView: UIPickerView!
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .green
recordPickerView = UIPickerView()
recordPickerView.frame = CGRect(x: 0, y: self.view.bounds.height / 2, width: self.view.bounds.width, height: 200)
recordPickerView.showsSelectionIndicator = true
recordPickerView.delegate = self
recordPickerView.dataSource = self
self.view.addSubview(recordPickerView)
}
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return recordtypeArray.count
}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return recordtypeArray[row]
}
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
print("select \(recordtypeArray[row])")
}
}

9到21行在viewDidLoad裡面實作並設定pickerView的大小、delegate、datasource
然後實作繼承UIPickerViewDelegate, UIPickerViewDataSource需要實作的numberOfRowsInComponent跟titleForRow
回傳前面設定的recordtypeArray的count跟內容
接下來回到RecordController修改一下sentButton()

let controller = RecordPickerController()
present(controller, animated: true, completion: nil)

其實蠻偷懶的只是將畫面推到RecordPickerController，接下來應該要讓推出來的畫面只是個子畫面
放一格在現在畫面中間就好，不過這就之後再加上去
這兩天想了想UI還是需要再做一些調整，看明天想先作哪邊ＸＤ
