Question

I have the following code and I cannot work out from the IOS developer documentation how to add some selection criteria (for the PHP) to the url

My php works when I add /?category=sports but how to I get this added to my kGETUrl string

NSURL *url = [NSURL URLWithString:kGETUrl];
NSData *data = [NSData dataWithContentsOfURL:url];

Answer 1

use stringWithFormat to add parameters.

NSString *urlString = [NSString stringWithFormat:@"%@/?category=sports", kGETUrl];
NSURL *url = [NSURL URLWithString:urlString];
NSData *data = [NSData dataWithContentsOfURL:url];

if you want to get sports part from a variable;

NSString *urlString = [NSString stringWithFormat:@"%@/?category=%@", kGETUrl, categorySelected];
NSURL *url = [NSURL URLWithString:urlString];
NSData *data = [NSData dataWithContentsOfURL:url];
