Question

我有一个textView和一个名为“发送”的按钮（不是来自键盘）。在结束输入评论时，我需要从此textView发送文字，但第一次点击时我会关闭键盘，第二次点击可以发送准确的评论。

    func textViewDidEndEditing(_ textView: UITextView) {
         textView.resignFirstResponder()
    }

    @IBAction func sendComment(_ sender: UIButton) { 
         comment() // POST to API
    }

    func comment() {
    let params: Parameters = [
        "text": commentTextView.text
    ]

    let id = topic?.id

    var request = URLRequest(url: url)!)
    request.httpMethod = "POST"
    request.allHTTPHeaderFields = Settings.sharedInstance.headers

    request.httpBody = try! JSONSerialization.data(withJSONObject: params)

    Alamofire.request(request)
        .responseJSON { response in
            switch response.result {
            case .failure(let error):
                print(error)

                if let data = response.data, let responseString = String(data: data, encoding: .utf8) {
                    print(responseString)
                }
            case .success(let responseObject):
                self.commentTextView.text = ""
                print(responseObject)
            }
    }
}

我需要在键入结束时按一下按钮并发送评论。

将UIGestureRecognizerDelegate添加到您的viewcontroller

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self.handleTap(_:)))
    tapGesture.delegate = self
    tapGesture.numberOfTapsRequired = 2
    view.addGestureRecognizer(tapGesture) //instead of view you can use your button here

将此代码添加到您的viewcontroller

中

func handleTap(_ sender:UITapGestureRecognizer){
   print("double tapped")
}

在键盘被隐藏之前按钮没有按下
