Question

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

arrayOfRestaurants = searchResponseJSON[@"businesses"];

NSDictionary *businesses = [arrayOfRestaurants firstObject];

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

我试图将数组中的所有数据都放入nsdictionary而不是第一个对象。有一个更好的方法吗？我似乎无法从数组中获取所有数据到nsdictionary

旁注：我对Objective c

非常新

Answer 1

只需在数组上使用for循环迭代，你就可以从那里得到每个对象并做你的东西。在得到所有对象之后，我不需要你告诉我，我会编辑我的答案

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

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

}

Answer 2

请尝试这个可能对您有所帮助

 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unordered collection of objects，但每个包含的值都是associated with a key,，其作用类似于标签。

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

1）直接插入数组元素，如下所示：

[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”];
您可以使用相同的密钥

将整个数组添加到nsdictionary
