Question

[NSPropertyListSerialization propertyListFromData:self.responseData 
                                 mutabilityOption:NSPropertyListMutableContainersAndLeaves                                                 
                                           format:&format 
                                 errorDescription:&errorDesc];

When the server is online, it sends the responseData. Now I want to save this data(obtained through the responseData in the code) directly to another plist in my app, so that I can retrieve the data later(when the server is offline) in the same format(without changing) and use it/pass it in the same way as it is being passed when my server is online. I am doing this so that the user of the app does not come to know whether the server is online/offline and still is able to give updates/feedback to the responseData (as he/she would give when the server is online).
I don’t want to break the responseData and save it, rather directly save it the way it is coming from the server.

Please let me know if more explanation is required.And thanks for all the answers that you would be giving 🙂

Answer 1

If you don’t want to change anything I believe you should just download the plist as a file and not as data.

To save the file on the phone you should use NSFileManager, you can read about it here:NSFileManager reference + File System Programming Guide

You must pay attention to the place you save the plist according to apple “new” rules of data storage, you can read about it here:
Were you should save your files

Good luck
