Open wallet APIs or open-source code for iOS, etc?

[JBCanDoIt]

Hi guys,

I've lurked for a long time but never registered for an account before. I've searched and didn't find, so I thought I would ask...

Are there any crypto-currency or BTC wallets out there that provide a good API for furthering development (through any protocols online)? Or, alternatively is there any open-source (good/up to date) iOS code that can help you implement a wallet into an application?

Thanks for any help!

Block.io  has a good and simple api service.
It's for bitcoin litecoin and dogecoin, and their testnet too.

I use blockchain.info api. It is easy to use and integrate with your wallet.
But it doesn't support altcoins.
