uitableview - Swift - 点击手势关闭键盘 UITableView

Question

我有一个与 this one 相同的问题，但由于我是编程新手，而且只真正了解 swift，所以我想知道是否有人可以在 swift 中给我它的等价物。或者指出我可能错过的另一个问题，那就是 swift 。

谢谢!

更新:这是我的 View Controller 的基本内容，在我削减了一些内容以仅处理相关主题之后。重述问题。直到我单击“完成按钮”运行 createClient() 函数并导航回客户端页面以编辑新创建的客户端后，点击手势才会关闭键盘。

import UIKit
import CoreData
import Foundation

class NewClientTableViewController: UITableViewController, UINavigationControllerDelegate, UITextFieldDelegate {

let managedObjectContext = (UIApplication.sharedApplication().delegate as AppDelegate).managedObjectContext

@IBOutlet weak var nameTxt: UITextField!
@IBOutlet weak var ageTxt: UITextField!
@IBOutlet weak var phoneTxt: UITextField!
@IBOutlet weak var emailTxt: UITextField!
@IBOutlet weak var heightTxt: UITextField!
@IBOutlet weak var notesTxt: UITextView!

var client: Client? = nil

override func viewDidLoad() {
    super.viewDidLoad()

    if client != nil {

        nameTxt.text = client?.name
        ageTxt.text = client?.age
        heightTxt.text = client?.height
        phoneTxt.text = client?.phone
        emailTxt.text = client?.email
        notesTxt.text = client?.notes

        self.title = client?.name
        phoneTxt.delegate = self

        let tapGesture = UITapGestureRecognizer(target: self, action: Selector("hideKeyboard"))
        tapGesture.cancelsTouchesInView = true

        tableView.addGestureRecognizer(tapGesture)

    }
}

func hideKeyboard() {
    tableView.endEditing(true)
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


@IBAction func doneButton(sender: AnyObject) {
    if client != nil {
        editClient()
    } else {
        createClient()
    }
    dismissViewController()

}

func editClient() {

    client?.name = nameTxt.text
    client?.age = ageTxt.text
    client?.height = heightTxt.text
    client?.phone = phoneTxt.text
    client?.email = emailTxt.text
    client?.notes = notesTxt.text
    client?.clientImage = UIImageJPEGRepresentation(contactImage.image, 1)

    managedObjectContext?.save(nil)
}

func createClient() {

    let entityDescription = NSEntityDescription.entityForName("Client", inManagedObjectContext: managedObjectContext!)
    let client = Client(entity: entityDescription!, insertIntoManagedObjectContext: managedObjectContext)

    if nameTxt.text == "" {
        client.name = "Untitled Client"
    } else {
        client.name = nameTxt.text
    }

    client.age = ageTxt.text
    client.height = heightTxt.text
    client.phone = phoneTxt.text
    client.email = emailTxt.text
    client.notes = notesTxt.text

    client.clientImage = UIImageJPEGRepresentation(contactImage.image, 1)

    managedObjectContext?.save(nil)

}

func dismissViewController() {
    navigationController?.popToRootViewControllerAnimated(true)
    }
}
