NSDictionary Count

Question

how can I count how many itens do I have inside of "bills"?

bills =     (
            {
        id = 1;
        name = "Cursus Nibh Venenatis";
        value = "875.24";
    },
            {
        id = 2;
        name = "Elit Fusce";
        value = "254.02";
    }
);

I'm counting this way:

NSUInteger keyCount = [resultsDictionary count];
NSLog(@"%i", keyCount);

Thanks!

Answer 1

A naive solution would assume the OP wants to count bills, which happens to be an array, so the solution would be

NSLog(@"Count: %i", [[resultsDictionary objectForKey: @"bills"] count]);

However, if you have a dictionary with more than one object you want to count, then enumerating them all is the only way to go.

Answer 2

NSUInteger keyCount = [resultsDictionary count];
NSLog(@"%i", keyCount); 

is true but also you can use [resultsDictionary allKeys]; which will return an array of keys and you can directly get its count. For more, please visit docs :v

Answer 3

NSMutableArray *billsArray =[[NSMutableArray alloc] init];
billsArray = [resultsDictionary valueForKey:@"bills"];//returns array
NSUInteger keyCount = [billsArray count];
NSLog(@"%i", keyCount);

I think it will be helpful to you.
