私はSqliteに文字列データを挿入しようとしたという問題があります。私はしたいと思う私の詳細ViewControllerユーザーが好きなViewControllerに表示されるSqliteファイルに文字列の単語と意味を渡すLikeボタンを押した場合。以下は私のDetailsVCコードです。Swift3の文字列からSqliteにデータを挿入する方法は？
import UIKit
import AVFoundation
class DetailsVC: UIViewController, UITextViewDelegate {
@IBOutlet weak var wordLbl: UILabel!
@IBOutlet weak var meaningLbl: UITextView!
@IBOutlet weak var sysWordLbl: UILabel!
@IBOutlet weak var sysWordsLbl: UILabel!
@IBOutlet weak var anyWordsLbl: UILabel!
@IBOutlet weak var anyWordLbl: UILabel!
@IBOutlet weak var wordImg: UIImageView!
@IBOutlet weak var buSound: UIButton!
@IBOutlet weak var buLike: UIButton!
@IBOutlet weak var menuBtn: UIButton!
//Data from HomeVC
var data:Data?
var fdatas = [FData]()
var favouriteVC = FavouriteVC()
override func viewDidLoad() {
super.viewDidLoad()
meaningLbl.delegate = self
wordLbl.text = "\((data?._word.capitalized)!) \((data?._phonetic)!)"
self.meaningLbl.text = data?._meaning
self.sysWordsLbl.text = data?._meaning
self.anyWordsLbl.text = data?._meaning
self.sysWordLbl.text = "Synonym"
self.anyWordLbl.text = "Antonym"
meaningLbl.font = UIFont(name: FONT_REGULAR, size: 24.0)
}
@IBAction func buMenu(_ sender: Any) {
//menu
dismiss(animated: true, completion: nil)
}
@IBAction func buSound(_ sender: Any) {
//Todo: speak the word
if buSound.isEnabled == true{
buSound.setImage(UIImage(named: "volume-2.png"), for: .normal)
}else{
buSound.setImage(UIImage(named: "volume-un-2.png"), for: .normal)
}
let utTerance = AVSpeechUtterance(string: "\((data?._word)!)")
let synthesize = AVSpeechSynthesizer()
utTerance.voice = AVSpeechSynthesisVoice(language: "en-gb")
synthesize.speak(utTerance)
}
@IBAction func buLike(_ sender: Any) {
//Todo: Click Like
if buLike.isEnabled == true{
buLike.setImage(UIImage(named: "heart.png"), for: .normal)
//Save data to Database
let word = data?._word ?? ""
let meaning = data?._meaning ?? ""
do{
let favData = FData(word: word, meaning: meaning)
self.fdatas.append(favData)
print("\(word), \(meaning)")
}catch{
print(error)
}
}else{
buSound.setImage(UIImage(named: "heart-un.png"), for: .normal)
}
//FavouriteVC.insertRowsAtIndexPaths([NSIndexPath(forRow: fdatas.count-1, inSection: 0)], withRowAnimation: .Fade)
}
func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool {
self.view.endEditing(true);
return false;
}
}

しかし、行のセルがFavouriteVCではありません。これを修正するには？私を助けてください。 ベスト、 サイタウンPha
あなたが本当に望むものを想像するのは少し難しいですが、あなたのView Controllerの画面を投稿できますか？ – YinKiet
はい、ここに私の詳細View Controllerのスクリーンショットがあります。 [ここ]（http://saitp.me/mac/details_vc.png） お気に入りのView Controllerスクリーンショット。 [ここをクリック]（http://saitp.me/mac/favourite_vc.png） 単語と意味をデータベースに保存します。そして、それをお気に入りのView Controllerに表示したい。お気に入りビューコントローラは、テーブルビューセルです。では、どうすればいいですか？ @YinKiet – SaiPha
