Array within a NSDictionary: how to save to the NSUserDefaults - iphone

Question

I would like to save Array/NSDictionary to NSUserDefaults but anything I try is just not working. Here is my code so please if you know how to do this, help me.
NSArray *oneArray = [NSArray arrayWithObjects:#"Radio One",nil];
NSDictionary *one = [NSDictionary dictionaryWithObject:oneArray forKey:#"Stations"];
NSArray *oneLinkArray = [NSArray arrayWithObjects:#"http://mobile.com:28000/",nil];
NSDictionary *oneLink = [NSDictionary dictionaryWithObject:oneLinkArray forKey:#"Stations"];
[data addObject:one];
[link addObject:oneLink];
The reason I need this is to put this station into favorites. So my thinking is to save these info in to NSUserDefaults and retrieve in favorites table.
Thanks and please any suggestion is welcomed and appreciated.

Answer 1

You can use something like this when you store everything into a dictionary
[[NSUserDefaults standardUserDefaults] setObject:link forKey:#"dictionary1"];
Or you can put everything into an array and store it like this
[[NSUserDefaults standardUserDefaults] setObject:data forKey:#"array1"];
You can access it again by using
NSDictionary * myDictionary = [[NSUserDefaults standardUserDefaults] dictionaryForKey:#"dictionary1"];

Answer 2

Typically adding an object into NSUserDefaults goes like this:
NSMutableDictionary *dictionaryToAdd = [[NSMutableDictionary alloc] init];
[dictionaryToAdd setObject:#"xyz" forKey:#"myKey"];
NSUserDefaults *myDefaults = [NSUserDefaults standardUserDefaults];
[myDefaults setObject:dictionaryToAdd forKey:#"someKey"];
[myDefaults synchronize];
A few things on your code above though - you're adding stuff into 'data' and 'link' but I don't see those in your code, so I'm assuming those arrays exist somewhere.
To sum it up - declare an NSUserDefaults object, set objects into it like an NSDictionary, and then synchronize it to save data.
Additional code as requested:
//You have an array named arrayToAdd that has already been created
NSUserDefaults *myDefaults = [NSUserDefaults standardUserDefaults];
[myDefaults setObject:arrayToAdd forKey:#"SomeKeyThatYouMakeUp"];
[myDefaults synchronize];
//You want to get the array out of NSUserDefaults
NSArray *mySavedArray;
NSUserDefaults *myDefaults = [NSUserDefaults standardUserDefaults];
mySavedArray = [myDefaults objectForKey:#"SomeKeyThatYouMakeUp"];
