Attempt to insert non-property value Objective C

Hi l am trying to create a fourates lists from an restaurants Object, my application has a list of different restaurants, l want the ability for users to add favourate restaurants, and this code is not working

- (IBAction)toggleFav:(id)sender {

    Restaurant *resto = [self restaure];

    NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];
    [dic setObject:resto.price forKey:@"restoPrice"];
    [dic setObject:resto.restaurantId forKey:@"restaurantId"];
    [dic setObject:resto.restoAbout forKey:@"restoAbout"];
    [dic setObject:resto.restoAddress forKey:@"restoAddress"];
    [dic setObject:resto.restoBeverages forKey:@"restoBeverages"];
    [dic setObject:resto.restoCategory forKey:@"restoCategory"];
    [dic setObject:resto.restoEmail forKey:@"restoEmail"];
    [dic setObject:resto.restoLogo forKey:@"restoLogo"];
    [dic setObject:resto.restoName forKey:@"restoName"];
    [dic setObject:resto.restoPhone forKey:@"restoPhone"];
    [dic setObject:resto.restoCity forKey:@"restoCity"];

    NSArray *dicArray = [dic allKeys];

    if([sender isSelected]){
        [sender setSelected:NO];
        NSMutableArray *array = [[[NSUserDefaults standardUserDefaults] objectForKey:@"restoName"] mutableCopy];
        [array removeObject:dicArray];
        [[NSUserDefaults standardUserDefaults] setObject:array forKey:@"restoName"];

    } else {
        [sender setSelected:YES];
        NSMutableArray *array = [[[NSUserDefaults standardUserDefaults] objectForKey:@"restoName"] mutableCopy];
        [array addObject:dicArray];
        [[NSUserDefaults standardUserDefaults] setObject:array forKey:@"restoName"];
        [[NSUserDefaults standardUserDefaults] synchronize];

       //NSLog(@"%@",[[NSUserDefaults standardUserDefaults] stringForKey:@"restoName"]);

' of class '__NSCFArray'. Note that dictionaries and arrays in property lists must also contain only property values.


If you don't want to bother about ensuring all your dictionary values are the property list types, then you can simply convert the dictionary into NSData,

NSUserDefaults *def = [NSUserDefaults standardUserDefaults];
[def setObject:[NSKeyedArchiver archivedDataWithRootObject:self.myDictionary] forKey:@"MyData"];
[def synchronize];

And to get back into a dictionary from sandbox:

NSUserDefaults *def = [NSUserDefaults standardUserDefaults];
NSData *data = [def objectForKey:@"MyData"];
NSDictionary *retrievedDictionary = [NSKeyedUnarchiver unarchiveObjectWithData:data];
self.myDictionary = [[NSDictionary alloc] initWithDictionary:retrievedDictionary];

Hope this helps someone. :D

ADDITIONAL NOTE: If you are getting a mutable dictionary, or mutable array, then remember to use "mutableCopy" method. Otherwise you can't add or delete objects from your retrieved dictionary/array. For example:

NSMutableDictionary *retrievedDictionary = 
[[NSKeyedUnarchiver unarchiveObjectWithData:data] mutableCopy];


NSMutableArray *retrievedArray = 
[[NSKeyedUnarchiver unarchiveObjectWithData:data] mutableCopy];

You can only store property list types (array, data, string, number, date, dictionary) or urls in NSUserDefaults. You'll need to convert your model object to those.
