Question

我正在寻找一种在SwiftUI的任意位置轻击/隐藏键盘的方法。在旧的Swift中，我可以轻松地向ViewController插入扩展，例如：

extension UIViewController {
func hideKeyboardWhenTappedAround() {
    let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(UIViewController.dismissKeyboard))
    tap.cancelsTouchesInView = false
    view.addGestureRecognizer(tap)
}

@objc func dismissKeyboard() {
    view.endEditing(true)
}

}

并在hideKeyboardWhenTappedAround()中呼叫viewDidLoad()

先谢谢您

您可以使用它，它应该可以工作！

func setupKeyboardDismissRecognizer(){
    let tapRecognizer: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(searchingActivity.dismissKeyboard))

    self.view.addGestureRecognizer(tapRecognizer)
}

@objc func dismissKeyboard()
{
    view.endEditing(true)
    searchTableView.isHidden = true
}

好吧，如果您需要使用UIViewController，则应在函数中使用扩展方法，如下所示：

override func viewDidLoad() {
    super.viewDidLoad()
    self.setupHideKeyboardOnTap()
}
//and the keyboard will be dismissed even by tapping on the NavigationBar.

import UIKit
extension UIViewController {
    /// Call this once to dismiss open keyboards by tapping anywhere in the view controller
    func setupHideKeyboardOnTap() {
        self.view.addGestureRecognizer(self.endEditingRecognizer())
        self.navigationController?.navigationBar.addGestureRecognizer(self.endEditingRecognizer())
    }

    /// Dismisses the keyboard from self.view
    private func endEditingRecognizer() -> UIGestureRecognizer {
        let tap = UITapGestureRecognizer(target: self.view, action: #selector(self.view.endEditing(_:)))
        tap.cancelsTouchesInView = false
        return tap
    }
}

在SwiftUI中轻按时是否有办法解散/隐藏键盘
