長押しでコピー可能なUILabel

Last updated at Posted at 2017-03-25

こんな感じで作れた。

swift

import UIKit

class CopyableLabel: UILabel {

    override init(frame: CGRect) {
        super.init(frame: frame)
        self.copyableInit()
    }


    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
         // IB上の設定を引き継ぎたい場合はコメントアウト
        self.copyableInit()
    }

    func copyableInit() {
        self.userInteractionEnabled = true
        self.addGestureRecognizer(UILongPressGestureRecognizer(target: self, action: #selector(CopyLabel.showContextMenu(_:))))
    }
    func showContextMenu(sender:AnyObject?) {
        self.becomeFirstResponder()
        let contextMenu = UIMenuController.sharedMenuController()
        if !contextMenu.menuVisible {
            contextMenu.setTargetRect(self.bounds, inView: self)
            contextMenu.setMenuVisible(true, animated: true)
        }
    }

    override func canBecomeFirstResponder() -> Bool {
        return true
    }

    override func copy(sender: AnyObject?) {
        let pasteBoard = UIPasteboard.generalPasteboard()
        pasteBoard.string = text
        let contextMenu = UIMenuController.sharedMenuController()
        contextMenu.setMenuVisible(false, animated: true)
    }

    override func canPerformAction(action: Selector, withSender sender: AnyObject?) -> Bool {
        if action == #selector(UIResponderStandardEditActions.copy(_:)) {
            return true
        }
        return false
    }
}
