can any help us how to pass array as a input parameter to the json service?
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];
You have to serialize the array and pass as an argument. Dont forget to unserialize in server side
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
