Swift 中未出现保存密码警报

Question

I want this alert to appear when the user logs in to my application.

I made this tutorial for this. iOS 12 Password Tools: Improving User Security and Experience

Also I have look this topic. And using this code in my LoginViewController.swift in viewDidDisappear or viewWillDisappear. But This alert does not appear at all.

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)

    if user.id != 0 {
        usernameTextField.text = nil
        passwordTextField.text = nil
    }

}

My entitlements file like this (Suppose that twitter.com is the website of my application):

<key>com.apple.developer.associated-domains</key>
<array>
    <string>applinks:twitter.com</string>
    <string>webcredentials:twitter.com</string>
</array>
<key>com.apple.developer.authentication-services.autofill-credential-provider</key>
<true/>

And off course my usernameTextField content type is username and passwordTextField content type is password .

So I want to ask why this alert didn't come off.

Answer 1

When creating a new account or changing the password, use the.newPassword text content type for the password TextField:

newPasswordTextField.textContentType = .newPassword
confirmPasswordTextField.textContentType = .newPassword

You can also manage iCloud Keychain Credentials using the Security.SecSharedCredentials API. It will still require a domain association (entitlements):

SecAddSharedWebCredential("your_domain.com" as CFString,
                           usernameTextField.text as CFString,
                           newPasswordTextField?.text as CFString, {(error) in })

Next, you should add the Apple App Site Association file to your website.

Create a file named apple-app-site-association (without an extension). Update the file to contain the JSON representation of a dictionary listing the app identifiers associated with your domain for the webcredentials service.

{
   "webcredentials": {
       "apps": [    "D3KQX62K1A.com.example.DemoApp",
                    "D3KQX62K1A.com.example.DemoAdminApp" ]
    }
}

Use the following format for the app identifiers:

<Team Identifier>.<Bundle Identifier>

Place this file either in your site's.well-known directory, or directly in its root directory. If you use the.well-known directory, the file's URL should match the following format:

https://<fully qualified domain>/.well-known/apple-app-site-association

You must host the file using https:// with a valid certificate and without using any redirects.

After the autofill password feature is implemented, the save password alert will show on you push or present (full screen) to next ViewController.
