Mobile Couchbase for iOS
Apache CouchDB on iOS provides a simple way to sync your application data across devices and provide cloud backup of user data. Unlike other cloud solutions, the data is hosted on the device by Couchbase Mobile, so even when the network is down or slow (airplane, subway, backyard) the application is responsive to users.
What this means for you:
- You can embed the rock solid distributed database, Mobile Couchbase, on your iOS device.
- Your iOS apps can use Apache CouchDB's well-proven synchronization technology.
- If you <3 CouchApps, you can deploy them as iOS apps.
If you just want to get started, jump to Building the Demo App. We've recently moved to Xcode 4, so for best results you should be on Xcode 4 also.
The biggest thing we need help with is size optimization - currently a Release build adds about 15 MB to your application. We are targeting 5 MB for our initial round of optimizations. It can definitely go lower but that work might take longer.
There is a Google Group here for Mobile Couchbase. Let's talk about how to optimize the Erlang build, what the best Cocoa APIs are for CouchDB, how to take advantage of replication on mobile devices. It'll be fun.
These instructions assume you are familiar with how to make an iPhone app because you've done it a lot already.
