Note: I am posting this because I don't even know what to Google search. I know we're all about thorough research before asking these questions. Any help would be appreciated.
Scenario: User writes a text post from my app and when they submit it, the content is added to a Parse.com class (I know how to do this) and simultaneously it is tweeted from a designated twitter account (that does not belong to the user) let's say @MyCoolAppThatTweets.
In other words, I don't want the user via my app to be permanently logged into @MyCoolAppThatTweets twitter account, but have one-time access to send a tweet from it.
Another way to phrase this question would be: How can my app log into a specific twitter account whose credentials I can "bake" into the app without compromising the security of that twitter account.
I am already aware that normally, users of an iOS app wouldn't automatically want their content being tweeted. For the project I'm making, this is not going to be a concern (it's a secret).
If you need more information or if I need to post this elsewhere, please let me know!
