Cocoa - Store an NSString value

Question

I want to store an NSString variable, that I receive from a JSON request, for future use. So when the user loads the app again, it loads that value (an NSString) that I stored.

What is the best way to store that kind of information?

Answer 1

NSUserDefaults is what you're looking for.

Save string:

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
[prefs setObject:theStringToSave forKey:@"keyToLookupString"];
[prefs synchronize];

Retrieve string:

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
NSString *theSavedString = [prefs stringForKey:@"keyToLookupString"];
