DSFSecureTextField

NSSecureTextField with a 'visibility' button.

Why

Sometimes it's nice to be able to see the contents of a password field. DSFSecureTextField adds a visibility button to the existing NSSecureTextField allowing your users to show or hide the contents of the field.

Optionally, you can choose to dynamically remove the button from the control (for example, if you want to be able to let your users choose whether to show the password or not via a preference)

Integrate

Copy the file DSFSecureTextField.swift into your project
Or, use CocoaPods

pod 'DSFSecureTextField', :git => 'https://github.com/dagronf/DSFSecureTextField/'
Or, use Swift Package Manager

Usage

Interface builder

Drag a Secure Text Field into the canvas
Set the Custom Class field for the control to DSFSecureTextField
Done!

Code

Since DSFSecureTextField inherits from NSSecureTextField, you can create it exactly as you would for an NSSecureTextField

Demo

There is a very simple project in the Demos folder.

Configuration

Parameter	Type	Description
`allowPasswordInPlainText`	`Bool`	If true, allows the control to display a plain text representation of the password. Useful if you want to be able to control whether the user can choose (eg. via preferences) to make the password visible.
`displayToggleButton`	`Bool`	If true, displays a button within the control (an eye) to allow the user to toggle between secure and plain text input
`visibility`	`Visibility`	If `.plainText`, the password is displayed in plain text.

`allowPasswordInPlainText`

A boolean flag to indicate if the field is allowed to display passwords in plain text.

If true, allows the control to display a plain text representation of the password. Useful if you want to be able to control whether the user can choose (eg. via preferences) to make the password visible.

`displayToggleButton`

When true, displays an 'eye' button embedded within the password field that allows the user to toggle the visibility of the password.

If true, displays a button within the control (an eye) to allow the user to toggle between secure and plain text input
If false (and allowPasswordInPlainText is true), the application needs to provide its own mechanism for setting visibility as appropriate.

`visibility`

The visibility flag denotes the visibility of the text within the field

Value	Description
`.secure`	The content is displayed securely (eg. `●●●●●●●●`)
`.plainText`	The content is displayed in plain text (eg. `gr00vy!.`)
