尝试插入非财产价值目标C(Attempt to insert non-property value

你好我上午试图创造一个fourates从餐厅列表对象，我的应用程序有不同的餐厅名单，L要为用户添加favourate餐厅的能力，而这种代码是不工作

- (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"]);
  }
}

'类‘__NSCFArray’。 需要注意的是字典和数组在属性列表也只能包含属性值。

Answer 1:

如果你不想理会确保您所有的字典中的值是属性列表类型，那么你可以简单地转换成字典NSData的，

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

而重新进入沙盒的字典：

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

希望这可以帮助别人。 ：d

附加说明：如果你得到一个可变的字典，或可变数组，然后记住使用“mutableCopy”的方法。 否则，你不能添加或删除您的检索字典/数组对象。 例如：

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

要么

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

Answer 2:

只能存储属性列表类型（阵列，数据，字符串，数字，日期，词典），或在网址NSUserDefaults的。 你需要你的模型对象转换为那些。
