Save NSDictionary in coreData

Question

I have to store dictionary in core data. I never worked with core data before.

Can anyone help me out that how can I use core data in my existing project and use it to store Dictionary.

after some google i get to know that i have to do archive and un-archive for doing this. But i didn't know how to implement it in project. — Gourav Gupta, Mar 12 '14 at 05:06

NSDictionary into Core Data like that you need to do

 NSMutableData *data = [[NSMutableData alloc] init];
    NSKeyedArchiver *archiver = [[NSKeyedArchiver alloc] initForWritingWithMutableData:data];
    [archiver encodeObject:yourDictionary forKey:@"dictpropertyinmanagedobject"];
    [archiver finishEncoding];
    [archiver release];
    [self.managedObject setValue:data forKey:@"dictpropertyinmanagedobject"];

NSDictionary from Core Data

NSData *data = [[NSMutableData alloc] initWithData:[yourManagedObject valueForKey:@"dictpropertyinmanagedobject"]];
NSKeyedUnarchiver *unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:data];
NSDictionary *yourDictionary=[[unarchiver decodeObjectForKey:@"dictpropertyinmanagedobject"] retain];
[unarchiver finishDecoding];
