I'm trying to hide the text of a UITextView, used as a password entry, using dots instead of the actual text. This text view is called TV_Password.
When its empty, the text should not be hidden and should be replaced by the string "Password"
I found on the net that the solution would be to change the following property to true.
self.TV_Password.secureTextEntry = true
Unfortunately, this still doesn't hide my text.
I moved the modifications to textViewShouldBeginEditing instead of textViewDidBeginEditing, as advised to people having this kind of issue, but it still doesn't work.
I haves various breakpoints telling me the instruction IS really done, but nothing happens..
Any idea .?
//MARK: TextViews editing
func textViewShouldBeginEditing(textView: UITextView) -> Bool {
if (textView == self.TV_Password){
if (self.TV_Password.text == "Password"){
//empty text
self.TV_Password.text = ""
//enable secured text
self.TV_Password.secureTextEntry = true
}
}
return true
}
func textViewDidEndEditing(textView: UITextView) {
if (textView == self.TV_Password) {
//if password empty
if (self.TV_Password.text == ""){
//disable secured text
self.TV_Password.secureTextEntry = false
//fill with the word "Password"
self.TV_Password.text = "Password"
}
}
}
ANSWER :
UITextView doesn't have a secure entry mode, use a UITextField instead.
Thanks a lot!

I currently have four text fields. At the beginning, only one text field shows. After the user enters text to the first text field and taps a button a new text field is presented and the previous one is hidden with the text field hidden property. My current code only shows the first text field, hides it and shows a new one, and stays in the second text field. There are still two more text fields that need to have the same functionality.
Can you explain why my current code is not working?
Thank you
This is my current code
if nameTextField.text != nil {
nameTextField.resignFirstResponder()
emailTextField.isHidden = false
nameTextField.isHidden = true
emailTextField.becomeFirstResponder()
} else if emailTextField.text != nil {
emailTextField.resignFirstResponder()
emailTextField.isHidden = true
firstPasswordTextField.isHidden = false
firstPasswordTextField.becomeFirstResponder()
} else if firstPasswordTextField.text != nil {
firstPasswordTextField.resignFirstResponder()
firstPasswordTextField.isHidden = true
phoneNumberTextField.isHidden = false
phoneNumberTextField.becomeFirstResponder()
} else if phoneNumberTextField.text != nil {
phoneNumberTextField.resignFirstResponder()
}
Hi Mathew the condition what you have written is incorrect . Lets say user first enter in nameTextField and then you are checking emailTextField not equal to nil.. Sone ones user enter in both the textfield , it is always going to satisfy the first condition only.. Just put a brteakpoint and check your logic.

How to edit old Secure Text without Storing data into Any Kind of String object
I'd suggest to create a custom UITextField class and override become​First​Responder() method do add your desired functionality:
You can override this method in your custom responders to update your
object's state or perform some action such as highlighting the
selection. If you override this method, you must call super at some
point in your implementation.
The custom Class should be similar to:
class CustomSecureTextField: UITextField {
override func becomeFirstResponder() -> Bool {
super.becomeFirstResponder()
if !isSecureTextEntry { return true }
if let currentText = text { insertText(currentText) }
return true
}
}
The logic of the implementation of becomeFirstResponder as follows:
By default, the secured-entry text field clears the inserted text when it is become first responder text, so what's happening in CustomSecureTextField that if the text field is secured-entry, it will re-insert the current inserted text -after clearing it-, but you have to make sure that the text field input is secured (that's the purpose of adding if !isSecureTextEntry { return true }) or the text will be duplicated (re-inserted) each time the text field becomes first responder.
Output:
Note that both of text fields are types of CustomSecureTextField:
This answer helped me to figure out this problem.
textField.isSecureTextEntry = true
following property not gonna work if you make testField isSecureTextEntrysecure property makes true .
textField.clearsOnBeginEditing = false
There is an issue with the #Ahmd F solution when you simply tap on the field it will automatically add the text to the field I have resolved that in the below code thanks
override open func becomeFirstResponder() -> Bool {
super.becomeFirstResponder()
if !isSecureTextEntry { return true}
if let currrentText = text {
self.text = ""
insertText(currrentText)
}
return true
}
Currently, I am setting autocapitalization in a button target like this
//This method is fired when keyboard is still active
- (IBAction)changeAutoCapitalization:(id)sender
{
self.textView.autocapitalizationType = UITextAutocapitalizationTypeWords;
}
But this won't make keyboard to capital.
You have to call [self.textView reloadInputViews] after modifying the UITextAutocapitalizationType in order to change keyboard immediately.
If you find that you're doing a lot of text-related customizations, it might be helpful to subclass UITextView, to keep the functionality encapsulated.
Note: If testing on the simulator, make sure you are using the
Simulator's keyboard, by going to the menu: I/O -> Keyboard -> Toggle
Software Keyboard
If you are adding text automatically, for instance in response to a button tap, and the shift key turns off, then you can use this pattern:
autocapitalizationType = .allCharacters //Activate shift key
autocorrectionType = .no //Don't show all-caps auto suggest
reloadInputViews() //Apply changes
Then, to restore to sentences capitalization, for instance when a line is cleared:
if (autocapitalizationType = .allcharacters) {
autocapitalizationType = .sentences //Activate sentence capitalization
autocorrectionType = .yes //Show auto suggest
reloadInputViews() //Apply changes
}
Other capitalization options:
.none
.words
You may also need to do this when any non-enter key is pressed. To do so, override insertText from UIKeyInput, and check the entered text string:
if (text != "\n") {
if (autocapitalizationType == .allCharacters) {
autocapitalizationType = .sentences //Activate sentence capitalization
autocorrectionType = .yes //Show auto suggest
reloadInputViews() //Apply changes
}
//Respond to any character sequences
//...
}
Try to add this after initialization:
self.textView.autocapitalizationType = UITextAutocapitalizationTypeWords;
OR
It's very likely that the "Auto-Capitalization" option is turned off on that device. You can find that option in Settings > General > Keyboard.
How to disable a save button until all the fields are filled in so it prevents the user from continuing until they enter something.
How can I do that in Swift?
First write a method to check for your textfield's text and only enable the button if the text fields contain valid text:
func checkField(sender: AnyObject) {
if textField1.text.isEmpty || textField2.text.isEmpty
{
yourbutton.enabled = false
}
else
{
yourbutton.enabled = true
}
}
Then call your function from the text field's delegate method textFieldDidEndEditingso that when the user finishes editing a field the button is enabled/disabled correctly.
I have a password textfield with a default value "password". The field is marked as secure. I'm trying to erase the default value once the user touch up inside the textfield.
- (IBAction)PasswordTouchUpInside:(id)sender
{
if (Password.text == #"Password")
{
Password.text = #"";
}
}
Is the touch up inside the wrong event?
You should compare strings using the method isEqualToString in the if condition:
if ([Password.text isEqualToString:#"Password"]) {
Password.text = #"";
}
Or, you can simply use the placeHolder property so that the UITextField does this behaviour automatically without you having to write PasswordTouchUpInside.
You probably want Touch Down, not up.
