将整个数组添加到 nsdictionary

Question

NSDictionary *searchResponseJSON = [NSJSONSerialization JSONObjectWithData:data options:0 error:&error];

arrayOfRestaurants = searchResponseJSON[@"businesses"];

NSDictionary *businesses = [arrayOfRestaurants firstObject];

NSString *businessesID = businesses[@"id"];

我正在尝试将数组中的所有数据放入 nsdictionary 而不仅仅是第一个对象。有一个更好的方法吗？我似乎无法将数组中的所有数据放入 nsdictionary

旁注：我是 Objective c

的新手

Answer 1

只需在数组上使用 for 循环迭代，您将从那里获取每个对象并执行您的 stuff.i 在您获取所有对象后不需要什么，只需告诉我，我将编辑我的答案

 NSDictionary *searchResponseJSON = [NSJSONSerialization JSONObjectWithData:data options:0 error:&error];
    if [searchResponseJSON[@"businesses"] isKindofClass: [NSDictionary class]] {
    arrayOfRestaurants = dictionary;

    for NSDictionary * dictionary in arrayOfRestaurants {
    print("dictionary")
    }

}

请试试这个，可能对你有帮助

 NSArray * myArray = [NSArray arrayWithObjects:@"hello", @"hi", @"hey"];

 NSDictionary * dict = [NSDictionary dictionaryWithObject:myArray forKey:@"threeLetters"];

 NSMutableDictionary * mutableDict = [NSMutableDictionary dictionaryWithCapacity:10];
 [mutableDict setObject:myArray forKey:@"threeLetters"];

Answer 3

NSDictionary 是一个 unordered collection of objects，但每个包含的值都是 associated with a key,，这就像值的标签。

NSArray * array = [NSArray arrayWithObjects:@"One",@"Two"@"Three",@"Four",nil];

1)直接插入数组元素如下图：

[NSDictionary initWithObjectsAndKeys:[NSArray arrayWithObjects:@"One",@"Two"@"Three",@"Four",nil], @"FirstKey", nil];

2) 在 NSDictionary 中插入 NSArray

NSDictionary * dict = [NSDictionary dictionaryWithObject:myArray forKey:@"FirstKey"];

Answer 4

NSDictionary *dictProducts=[response valueForKey:kViewModel];

将对象添加到数组

 [_yourArray addObject:[dictProducts objectForKey:kProductID]];
    NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
    [dict setObject: _yourArray forKey:@"Your_Key"];

您可以在class中使用相同的键
