How to make a favourite list iphone

I am making an app that has two tabs, one of which is a "favourite" tab. In the other tab called "search", I have a list of results displayed in a table view, when you tap one, you get to see the detail of that particular result. What I'm trying to do here is, there is a button in the detail view, when it is pressed, the current result gets sent to the "favourite" tab. I tried to use delegate to pass the information, but it didn't work out. Here is my code:

DetailViewController.m

-(IBAction) addSomething {  
    [self.delegate detailViewController:self addToFavourite:self.something];
}

FavouriteViewC开发者_运维百科ontroller.m, implement the delegate method:

- (void) detailViewController:(DetailViewController *)detailViewController addToFavourite:(Something *)something{
    detailViewController.delegate = self;
    [thingsList addObject:something];
    [theTableView reloadData];
}

Everything is built and fine, but when I click "add" button in the detail view, the data doesn't get sent to "favourite" tab's view. Can anyone help me with this one? Do I need to use core data in this case, I never used core data before. Thanks.

One way to do it that is drop dead easy is storing your information in NSUserDefaults.

NSUserDefaults *defaults = [NSUserDefaults standardDefaults];
[defaults setObject:thingsList forKey:@"myData"];
[defaults synchronize];

When you load your data up in your other tab, just fill it from user defaults.

NSUserDefaults *defaults = [NSUserDefaults standardDefaults];
otherData = [defaults objectForKey:@"myData"];

I probably abuse user defaults more than I should, but it makes for a very easy way to store your data locally and have it persist between runs. It will also backup with iTunes for added persistence. Hope this helps.
