React Native Password TextInput - Store credentials in iOS

I have 2 TextInputs in a LoginScreen, one configured for email as username and the other configured for password. When I log in in Android, Android ask me if I want to store credentials, but iOS does not. How do I have to configure it so iOS asks as well? The way it is configured right now, iOS allow me to populate both fields with data from keychain if I select the right option in keyboard.

Password AutoFill for iOS App

In iOS 11 they have introduced password autofill which fills the username and password in iOS app like the same way it does in Safari, User goes to website first, logged in save the username and password in keychain and then open app were the fields are automatically populated, the username and password
can it be implemented in other ways, like I logged in the app first and then while going on the website through Safari it automatically fills the username and password?
Is there any documentation or articles regarding it?
Editing My Answer:
Looks like it is possible to do so. The same kind of association we can see in SharedWebCredentials which is released in iOS8. Using SharedWebCredentials doing in both ways is possible. From app to website and website to app. Assuming Password autofill in iOS11 has done on top of this.
Here is how the association will happen.
We have entitlement certificate for an app where we will provide domain to be linked with. Then we have a website where we will hold information in JSON format related to that website. In that JSON, you have to put your bundle identifier. So when the user saves this passwords and logs in through app. Then the app entitlement file will provide the web address to safari. Safari will bring that JSON file and validate the bundle identifier is same or not. If validation success it will populate username and password.

I asked about this at the developer labs at WWDC and was informed that it's possible. The key is that the new password autofill is based on the existing Shared Web Credentials API, which works both ways. If you use that API to save credentials from your app, they'll be available in Mobile Safari. Shared Web Credentials was the topic of a 2014 WWDC session.
I haven't tried it yet, but based on the source I'm pretty confident that it should work.

saving password for springboard webapps

I'm creating an html application using form authentication. If I open this application using Safari on iOS and complete the login screen, iOS asks me if I want to save my credentials.
but it doesn't work the same way if I add this webapp as a link on the springboard. In that case, iOS doesn't ask me to save my credentials.
Is there a way to force iOS to show me the possibility to save my credentials ?

Salesforce OAUTH implementation

I'm developing Salesforce iOS application.
From application frequently the user has to modify data which is available on Salesforce.com.
When user tap on edit I'm launching salesforce login screen and prompt to enter username and password all the time.
So I have decided to implement SSO using Salesforce Oauth. I have done everything I'm able to receive a access_token once user authenticate with Salesforce.com.
My question is lets say "If the user want to edit a lead with id as 0097hjy7" , URL to edit this lead will be "https://sales.mysalesforce.com/0097hjy7" when this URL launch on browser it prompt to enter username and password again.
How can I navigate the user to "https://sales.mysalesforce.com/0097hjy7" this URL without asking username and password all the time by using the access_token available with me.
Thanks in advance.
I resolved this issue by adding Salesforce iOS SDK to my project and using some classes like SFOauthCoordinator and SFOauthCredentials. At the end we need to prepare a frontDoorUrlWithReturnUrl which is available on "SFAuthenticationManager" class.

How can i show an inputdialogbox in blackberry where it asks for Username and Password before my application is opened

My requirement is to create a Blackberry Application Where it needs Authentication to open. Right now I created an Simple Blackberry Application Which can be opened by anyone. But I need to put a Dialogbox where it asks for username and Password. Once the credentials are valid then only the app should load. For the time being i need a dialgbox when the my app is clicked. Validation of the credentials can be done at later point of time.
