跟蹤應用程序 Swift 中的所有用戶觸摸

Question

我在 stackoverflow 上搜索了大約一個星期，關於我想跟蹤所有用戶觸摸的問題，但沒有成功，我知道有很多這樣打開的問題，但不是我正在尋找的具體問題。

我想要的：跟蹤所有用戶觸摸，包括例如按下 UIButton 或按下 UITextfield 或打開某些 ViewController 等等。 但是：為什么這個問題不同，我想要一些標簽文本來解釋按下了哪個按鈕，例如，如果我有 LoginVC 並且有登錄按鈕，我想要方法來解釋“按下登錄按鈕”或“忘記按下按鈕”然后記錄此事件/觸摸。

提前致謝！

您可以創建一個 BaseViewController，並向其視圖添加一個點擊手勢識別器，然后確定哪個子視圖被點擊，如下所示：

class BaseViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let tapRecognizer = UITapGestureRecognizer(target: self, action: #selector(viewDidTap(_:)))
        tapRecognizer.delegate = self
        tapRecognizer.cancelsTouchesInView = false
        self.view.addGestureRecognizer(tapRecognizer)
    }

    @objc func viewDidTap(_ recognizer: UITapGestureRecognizer) {
        guard let view = recognizer.view else { return }

        let location = recognizer.location(in: view)
        let subview = view.hitTest(location, with: nil)
        self.log(tappedView: subview ?? view)
    }

    func log(tappedView: UIView) {
        // do some base job with the tapped view
    }

}

extension BaseViewController: UIGestureRecognizerDelegate {
    func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldBeRequiredToFailBy otherGestureRecognizer: UIGestureRecognizer) -> Bool {
        let location = gestureRecognizer.location(in: self.view)
        guard let textField = self.view.hitTest(location, with: nil) as? UITextField else { return false }

        textField.becomeFirstResponder()
        return true
    }
}

現在您可以擴展其他視圖控制器以具有BaseViewController的功能並覆蓋log方法，如下所示：

class ChildViewController: BaseViewController {

    let forgotButton = UIButton()
    let signinButton = UIButton()

    override func log(tappedView: UIView) {
        super.log(tappedView: tappedView)

        if (tappedView === self.forgotButton) {
            labelLog.text = "Forgot button was tapped"
        } else if (tappedView === self.signinButton) {
            labelLog.text = "Sign In button was tapped"
        }
    }
}
