efficient for querying large plists?

I am planning to do search on large plists. say around 900 plists with开发者_高级运维 data ranging from 120 to 250kb. which one is efficient for searching large plist ?? core data or sqlite ?

The answer is: don't do that.

Instead, import all of this data into Core Data and then do everything else within Core Data. plist files are not good for this at all. If you are receiving the data from a server in plist format then great, import it into Core Data.

If you have control of the output of the server then I highly recommend using JSON instead. You can set up the data structures to make your import into Core Data very easy to manage, far easier than dealing with plists.
