核心数据，iCloud和Cloudkit

Question

I am in the planning stage of a new project that will require to use Core Data. It has these requirements: 1. Be able to access same data across multiple devices. 2. Be able to access same data in offline or online 3. Guarantee data will not be lost.

Couple years ago, I embarked on similar project. But I had to abandon these features.

Does Core Data with iCloud syncing work well enough for current iOS 7 and 8 to warrant another attempt?

If not, I am thinking about using CloudKit and local Core Data storage. But then I will have to write extra code to update both.

Any suggestions?

您可以使用https://github.com/evermeer/EVCloudKitDao这是一个CloudKit库，支持本地缓存（不是Core Data，而是使用NSCoding的文件）
