Formatterを触る

参考

コード例

  • IBでNSFormatterしかない？のかプログラム上で設定した。
    @IBOutlet weak var customURLFormatTextField: NSTextField!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do view setup here.
        
        let formatter = CustomURLFormatFormatter()
        customURLFormatTextField.formatter = formatter
    }
  • NSTextField上でEnterをすると空になったり挙動がおかしくなったので一旦採用保留。
import AppKit

class CustomURLFormatFormatter: Formatter {
    
    // MARK: - Override
    
    override func string(for obj: Any?) -> String? {
        guard let customFormat = obj as? String else {

        return customFormat

        let service = NSSharingService(named: NSSharingService.Name.composeEmail)!
        service.recipients = ["メールアドレス"]
        service.subject = "\(appName) \("issueReport".localized)"
        service.perform(withItems: [

ですです！
先日きょめさんに連絡フォームの実装を勧めてもらったので実装を考えてみました。
（文言に関してはRunCatとCotEditorのものを参考にしました！）

infoStringのextensionは便利そうでいいですね、参考にさせてもらいます〜。
