鍵盤隱藏UITextView swift 2

Question

我使用帶有2個海關單元的UITableView ，我有UITextView和UITextField自定義單元格，當它被鍵盤頂部的鍵盤隱藏時，我試圖向上移動編輯的字段，這是我的viewDidLoad代碼：

 override func viewDidLoad() {
        super.viewDidLoad()
 let notificationCenter = NSNotificationCenter.defaultCenter()
        notificationCenter.addObserver(self, selector: #selector(adjustForKeyboard), name: UIKeyboardWillShowNotification, object: nil)
        notificationCenter.addObserver(self, selector: #selector(adjustForKeyboard), name: UIKeyboardWillHideNotification, object: nil)
        notificationCenter.addObserver(self, selector: #selector(adjustForKeyboard), name: UIKeyboardWillChangeFrameNotification, object: nil)

    }

這里是發送鍵盤通知時調用的函數：

func adjustForKeyboard(notification: NSNotification) {
    let userInfo = notification.userInfo!

    let keyboardScreenEndFrame = (userInfo[UIKeyboardFrameEndUserInfoKey] as! NSValue).CGRectValue()
    let keyboardViewEndFrame = view.convertRect(keyboardScreenEndFrame, fromView: view.window)

    if notification.name == UIKeyboardWillHideNotification {
        myTableView.contentInset = UIEdgeInsetsZero
        print("ZERO")
    } else {
        myTableView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: keyboardViewEndFrame.height, right: 0)
    }

    myTableView.scrollIndicatorInsets = myTableView.contentInset
}

它適用於UITextField但不適用於UITextView 。 為什么？

由史蒂夫回答（ 用uiTextView解雇鍵盤 ）

import UIKit

class ViewController: UIViewController, UITextViewDelegate {

    @IBOutlet weak var textView: UITextView!

    override func viewDidLoad() {
        super.viewDidLoad()

        textView.delegate = self
    }

    func textView(textView: UITextView, shouldChangeTextInRange range: NSRange, replacementText text: String) -> Bool {
        if(text == "\n") {
            textView.resignFirstResponder()
            return false
        }
        return true
    }

}
