you will need to create an NSMutabelDictionary of your array then JSON encode it, you can then send the resulting string you your webservice however you choose. I tend to build a POST request and send it that way

NSMutableDictionary *jsonDict = [[NSMutableDictionary alloc] init];
NSMutableDictionary *tagData = [[NSMutableDictionary alloc] init];
for(int i = 0; i < array.count; i++)
{
    NSString *keyString = [NSString stringWithFormat:@"key%i", i];
    [tagData setObject:[array objectAtIndex:i] forKey:keyString];
}

[jsonDict setObject:tagData forKey:@"entries"];

NSData* data = [NSJSONSerialization dataWithJSONObject:jsonDict
                                               options:NSJSONWritingPrettyPrinted error:&error];

NSString* aStr;
aStr = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

It is the sgtring aStr that you need to send

You have to serialize the array and pass as an argument. Dont forget to unserialize in server side

First you have to convert array as JSON string 

NSString *requestString=[jsonParser stringWithObject:array];

convert string to data 

NSData *data=[requestString dataUsingEncoding:NSUTF8StringEncoding];

set that data as request Body 

[request setHTTPBody:data];
