OAuth in iOS

[Navarjun]

Hello everyone

I am trying to get OAuth work on iOS… I tried a lot, believe me I have been trying since yesterday, and it's already today evening. There is an library that I found, but I cannot use it as it uses deprecated methods… and Apple will reject my app as soon as I submit.

I followed the documentation on OAuth website. There is also a link that I followed:
https://www.cubrid.org/blog/dancing-w...

Can someone document the requests needed to get OAuthorization for goodreads API.
I am looking for following things:
- What requests do I need to make? (and in what order)
- What should be the link I send users to?
- What are the headers/url parameters/body parameters that I need to send for each request?
- What is the "base signature string" for each request?

Thanks in advance!

Are you writing in Swift?
I used OAuthSwift and just followed the documentation on their github to get it up and running: https://github.com/OAuthSwift/OAuthSwift

Can you provide the sample code which uses SafariViewController?

Here you go. The SafariURLHandler function in OAuthSwift creates a SafariViewController for you (you can even set a delegate to it if you want to handle failure states better)

For me the SafariViewController is never popped back… and neither success or failure is called. Does that happen for you?

I know I am missing something really stupid

Also, what is AuthStorageService in the sample code?

Thanks a lot for doing this.

That's weird. Have you set up your AppDelegate/info.plist to respond to Return URLs like at the start of the How To section of https://github.com/OAuthSwift/OAuthSwift ? That should allow OAuthSwift to handle it automatically.

Oh, I created an AuthStorageService that saves the Auth Token & Secret in the keychain and retrieves them again later. It just saves the app needing a login every time it's reopened. I meant to remove it from the gist!

Yes, I did that… but it's not working :(

Oh, great!
It worked now… I realised my mistake… there was a typo in the AppDelegate String…


func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
if (url.host == "oauth-calback") {
OAuthSwift.handle(url: url)
}
return true
}


callback was spelled calback

Thanks a lot for helping me figure this out.

Haha! Happens to the best of us :)
Best of luck with your app!
