Weathermap API not able to parse completely in iOS - ios

Question

I'm able to retrieve data from the weather map api, however I can't figure out how to exactly parse the data. I'm able to do it only for a certain part of it.
This is the JSON data:
{
base = "cmc stations";
clouds = {
all = 56;
};
cod = 200;
coord = {
lat = "29.66";
lon = "-82.3";
};
dt = 1403641995;
id = 4156404;
main = {
humidity = 74;
pressure = 1018;
temp = "304.08";
"temp_max" = "306.48";
"temp_min" = "302.15";
};
name = Gainesville;
rain = {
3h = 0;
};
sys = {
country = US;
message = "0.2087";
sunrise = 1403605821;
sunset = 1403656392;
};
weather = (
{
description = "broken clouds";
icon = 04d;
id = 803;
main = Clouds;
}
);
wind = {
deg = 153;
gust = "1.54";
speed = "0.51";
};
}
Now I am able to get only one part of it :
base = "cmc stations"
like this:
- (void)fetchedData:(NSData *)responseData {
//parse out the json data
NSError* error;
NSDictionary* json = [NSJSONSerialization JSONObjectWithData:responseData //1
options:kNilOptions
error:&error];
NSLog(#"values %#",json);
NSLog(#"Checking values ------------ %#",[json objectForKey:#"cloud"]);
}
But when I try to do the same for other fields like
clouds
coord
main
I can't. I get a null value.
I'm guessing I need an additional NSDictionary or NSArray but just not sure how to go about it. Can someone please tell how can I do this? I'm mainly looking to get data from the main block :
humidity
temp
temp_max
temp_min
rain
sunrise
sunset
I think I have found a solution:
Here's how I'm getting the data:
NSString* base = [json objectForKey:#"base"];
NSLog(#"Value of first base variable: %#",base);
// NSArray* base = [json objectAtIndex:0];
NSArray *clouds = [json objectForKey:#"clouds"];
NSLog(#"Value of first clouds‹ variable: %#",clouds);
NSArray *coord = [json objectForKey:#"coord"];
NSLog(#"Value of first coord variable: %#",coord);
NSDictionary *main = [json objectForKey:#"main"];
NSLog(#"Value of first coord variable: %#",main);
NSArray* humidity = [main objectForKey:#"humidity"];
NSLog(#"humidity levels found manually : %#",humidity);
NSArray* temp_max = [main objectForKey:#"temp_max"];
NSLog(#"max temp levels found manually : %#",temp_max);

The problem is that most of those values are dictionaries, not arrays. When you see { } and colons (:) that will generally indicate the presence of a dictionary of key-value pairs, even though some of them may only have one such pair which might make it appear like an array or a stand-alone object.
To get clouds for instance:
NSDictionary *clouds = [json objectForKey:#"clouds"];
NSNumber *allClouds = [clouds objectForKey:#"all"];
NSLog(#"Value of first clouds‹ variable: %#",allClouds);
To get coord:
NSDictionary *coords = [json objectForKey:#"coord"];
NSNumber *lon = [coords objectForKey:#"lon"];
NSNumber *lat = [coords objectForKey:#"lat"];
NSLog(#"Value of lon is: %#",lon);
