NSDictionary to NSUserDefaults

Is there a way to store NSDictionary keys and objects to NSUserDefaults? I mean i know you can...

NSUserDefaults *defs = [NSUserDefaults standardUserDefaults];

[defs setObject:[myDictionary objectForKey:@"myKey"] forKey:@"myKey"]; // continue for every object

But is there some sort of initialization I can do? Basically something that creates the NSUserDefaults from the dictionary. If not I guess ill just have to keep manually adding all the objects every time. Thanks.

Hey Derek,

In iOS everything is possible :). Here is the solution for you:

NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:@"Pavel", @"FirstName", @"Palancica", @"LastName", nil];

NSUserDefaults *defs = [NSUserDefaults standardUserDefaults];

[defs registerDefaults:dict]; [defs synchronize];

NSLog(@"First Name = %@", [defs objectForKey:@"FirstName"]); NSLog(@"Last Name = %@", [defs objectForKey:@"LastName"]);

Hope it saved your day.

Regards!!!
