모든 UITextField textContentType을 양식으로 설정 UITextContentType("")하거나 .oneTimeCode깨끗한 솔루션이 아니라고 생각 합니다. 활성화 / 비활성화는 isSecureTextEntry여전히 동일한 문제를 제공합니다.
@Gal Shahar의 답변은 좋지만 여전히 완벽하지는 않습니다. 마스크 된 문자는 애플의 보안 입력 텍스트에 사용 된 마스크 문자와 동일하지 않습니다. 유니 코드 문자 'BLACK CIRCLE'(U + 25CF) https://www.fileformat.info/info/unicode/char/25cf/index.htm을 사용해야합니다.
또한 커서 이동을 처리하지 않습니다. 중간에 텍스트를 삽입 할 때 커서 위치가 텍스트의 끝으로 변경됩니다. 텍스트를 선택하고 바꿀 때 잘못된 값을 제공합니다.
자동 완성 암호를 피하기 위해 사용자 지정 isSecureEntryText를 사용하기로 결정한 경우 다음 코드가 있습니다.
Swift 5 (단순 버전)
@IBOutlet weak var passwordTextField: UITextField!
var maskedPasswordChar: String = "●"
var passwordText: String = ""
var isSecureTextEntry: Bool = true {
didSet {
let selectedTextRange = passwordTextField.selectedTextRange
passwordTextField.text = isSecureTextEntry ? String(repeating: maskedPasswordChar, count: passwordText.count) : passwordText
passwordTextField.selectedTextRange = selectedTextRange
}
}
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
if textField == passwordTextField {
if let swiftRange = Range(range, in: passwordText) {
passwordText = passwordText.replacingCharacters(in: swiftRange, with: string)
} else {
passwordText = string
}
textField.text = isSecureTextEntry ? String(repeating: maskedPasswordChar, count: passwordText.count) : passwordText
if let newPosition = textField.position(from: textField.beginningOfDocument, offset: range.location + string.utf16.count) {
textField.selectedTextRange = textField.textRange(from: newPosition, to: newPosition)

textContentType속성을 다음으로 설정해보십시오..textContentTypeiOS 11에 필드 가 사용자 이름 / 암호 필드 가 아님 을 알리고 액세서리보기가 표시되지 않도록해야합니다. `self.passwordField.textContentType = .textContentType`과 같은 것
