How to parse json first objects without key in objective c?

Question

I need to parse json form this link https://raw.githubusercontent.com/David-Haim/CountriesToCitiesJSON/master/countriesToCities.json

This file stores the country names as a key, and as city values located in these countries

How to pull the city by the key of the country I know, here is an example with China

NSDictionary *dict = [self JSONFromFile]; 
NSArray *city = [dict objectForKey:@"China"]; 
NSLog(@"Colour name: %@", city);

But I first need to get all the names of countries, which would then give the user the choice of the country for further action.

It's not clear what you want but if you're looking to discover all the keys in a dictionary you can use [dict allKeys] — Rob Sanders

Fetch the JSON response and store it in a Dictionary and then use the below code to iterate each key value pair in this dictionary.

For Objective C

[dictionary enumerateKeysAndObjectsUsingBlock:^(id key, id value, BOOL* stop) {
    NSLog(@"%@ => %@", key, value);
    // This block will iterate for each (key,value) pair in the dictionary.
}];

For Swift 3.0

for (key, value) in dictionary {
    print(key, value)
    // This block will iterate for each (key,value) pair in the dictionary.
}
