This is a valid json format. I have checked it with http://jsonlint.com/ and using http://braincast.nl/samples/jsoneditor/
see the structure of json value.According to structure the people tag should return count of 2, as it has 2 objects, but it is returning only 1 while parsing.
I am completely out of options. Please help guys.
This is the code i am using for parsing
NSString *textPAth = [[NSBundle mainBundle] pathForResource:#"sync" ofType:#"json"];
NSError *error;
NSString *content = [NSString stringWithContentsOfFile:textPAth encoding:NSUTF8StringEncoding error:&error];
NSArray *jsonArray = [[content JSONValue] retain];
NSLog(#"JSON ARRAY %# AND COUNT %d",[[jsonArray valueForKey:#"updates"] valueForKey:#"people"],[[[jsonArray valueForKey:#"updates"] valueForKey:#"people"] count]);

Answer 1

I'm not sure why every dictionary is wrapped with an array, when there is only 1 entry (unnecessary), but if you want to parse it you'd want something like this:
NSDictionary *jsonDict = [[content JSONValue] retain];
NSArray *updatesArray = [jsonDict objectForKey:#"updates"];
NSDictionary *updatesDict = [updatesArray objectAtIndex:0];
NSArray *peopleArray = [updatesDict objectForKey:#"people"];
NSLog(#"People count: %i", [peopleArray count]);
for (NSDictionary *peopleDict in peopleArray) {
//do something
}
As a side note, if this is your JSON, you'll want to remove the [arrays] for entries that are not actually arrays. While you can still parse it, it means you'll have to read the array first then get the dictionary from the objectAtIndex:0, which is totally inefficient and pointless.

Answer 2

Could it be that every one of your objects is wrapped in an array and giving unexpected results?
