私はスクロールビュー内のビューに存在するフォームを作成しています。 2つのtextFieldと1つのtextViewが含まれています。私はオンラインリソース（like this one）からいくつかのコードを一緒に飾ったので、textFieldがビュー上であまりにも低く、キーボードによって遮られているとスクロールアップします。問題は、textViewsでは動作しないように見えるということです。スクロールビューをトリガしてキーボードを動かすためにテキストビューを取得するにはどうすればよいですか？
私は、textViewsが同じ動作を引き起こさない理由を理解するために最善を尽くしましたが、私は実際にいくつかの助けを使うことができます。私のVCコードは次のとおりです：
import UIKit
class AddAPlaceBasicInfoViewController: UIViewController, UITextFieldDelegate, UITextViewDelegate {
// Outlets
@IBOutlet weak var nameTextField: UITextField!
@IBOutlet weak var categoryTextField: UITextField!
@IBOutlet weak var descriptionTextView: UITextView!
@IBOutlet weak var nextButton: UIButton!
@IBOutlet weak var scrollView: UIScrollView!
override func viewDidLoad() {
super.viewDidLoad()
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(noti:)), name: NSNotification.Name.UIKeyboardWillHide, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(noti:)), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
// Default to an disabled "Next" button.
nextButton.isEnabled = false
nextButton.backgroundColor = UIColor(red: 89/255, green: 89/255, blue: 89/255, alpha: 1/1)
// Check that fields are filled.
nameTextField.delegate = self
descriptionTextView.delegate = self
// Helper functions.
createToolbar()
descriptionTextViewSetup(descriptionTextView)
}
// Creates the done button above the category picker.
func createToolbar() {
// Creates an instance of UIToolbar() named "toolbar".
let toolbar = UIToolbar()
toolbar.sizeToFit()
// Set up button properties.
let doneButton = UIBarButtonItem(title: "Done", style: .plain, target: self, action: #selector(AddAPlaceBasicInfoViewController.dismissKeyboard))
// Set color to teal.
doneButton.tintColor = UIColor(red: 0/255, green: 134/255, blue: 111/255, alpha: 1)
// Set up button in the toolbar and make it interactive.
toolbar.setItems([doneButton], animated: false)
toolbar.isUserInteractionEnabled = true
// Add the toolbar as an accessory view to the category picker.
nameTextField.inputAccessoryView = toolbar
categoryTextField.inputAccessoryView = toolbar
descriptionTextView.inputAccessoryView = toolbar
// Set toolbar's background to white.
toolbar.backgroundColor = UIColor.white
}
// Function to dismiss the keyboard. Used when the user taps the "Done" button in the toolbar.
func dismissKeyboard() {
view.endEditing(true)
if nameTextField.text?.characters.count == 0 || categoryTextField.text?.characters.count == 0 || descriptionTextView.text == "What's this place like? (You'll be able to add a photo on the next screen)" {
nextButton.isEnabled = false
nextButton.backgroundColor = UIColor(red: 89/255, green: 89/255, blue: 89/255, alpha: 1/1)
} else {
nextButton.isEnabled = true
nextButton.backgroundColor = UIColor(red: 0/255, green: 134/255, blue: 111/255, alpha: 1/1)
}
}
// Function to create placeholder text.
func descriptionTextViewSetup(_ textView: UITextView) {
// Modifications
descriptionTextView.text = "What's this place like? (You'll be able to add a photo on the next screen)"
descriptionTextView.textColor = UIColor(red: 199/255, green: 199/255, blue: 205/255, alpha: 1/1)
descriptionTextView.textContainer.lineFragmentPadding = 0
//descriptionTextView.textColor = UIColor.lightGray
}
//---------------------------------
// MARK: - Notification Center
//---------------------------------
func keyboardWillHide(noti: Notification) {
let contentInsets = UIEdgeInsets.zero
scrollView.contentInset = contentInsets
scrollView.scrollIndicatorInsets = contentInsets
}
func keyboardWillShow(noti: Notification) {
guard let userInfo = noti.userInfo else { return }
guard var keyboardFrame: CGRect = (userInfo[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue else { return }
keyboardFrame = self.view.convert(keyboardFrame, from: nil)
var contentInset:UIEdgeInsets = scrollView.contentInset
contentInset.bottom = keyboardFrame.size.height
scrollView.contentInset = contentInset
}
}
