本地数据库解析Xcode

Question

I have an application in Xcode, and the application linked a database on Parse .. It brings news from Parse and displays it in TableView ..

But the problem is, if the user had lost contact with the Internet, it does not display anything, just a white screen I want to show me the latest news that have appeared since the last connection

Answer 1

Parse has a good way to cache data if the connection is lost. Try adding:

query.cachePolicy = kPFCachePolicyNetworkElseCache;

to your query and run it. First with and then without connection. This is a good guide that explains it a little bit deeper: https://parse.com/docs/osx/api/Constants/PFCachePolicy.html

Cheers!
