Question

I am currently working on a project where I woud, parse the JSON and store a JSON Object into an array.

I do something like this:

NSArray *value = [JSONObject valueForKey:@"value"];

I have all my values in the array value.

How would I, collect the last 10 values from this array and store it in a second array?

Any help is really appreciated.

Thank you very much in advance.

Take a look at this method. (Here is a link to the documentation.)

- (NSArray *)subarrayWithRange:(NSRange)range;

So in your case it would be:

NSArray *value = [JSONObject valueForKey:@"value"];
NSRange endRange = NSMakeRange(value.count >= 10 ? value.count - 10 : 0, MIN(value.count, 10));
NSArray *lastTenObjects= [value subarrayWithRange:endRange];
