Trying out Push Notification Example on Advanced Iphone Projects "Apress"

Question

hello all im trying out the chapter 10 example on push notifications. dont know if anyone has read it, its a really great article on push notifications. the code seems fine, the only problem i have is when i use

NSString *registerResult = [NSString stringWithContentsOfURL:[NSURL URLWithString:getURLString]]; it give me a warning that it is depreciated in iPhone 3.0, so i searched for a change i found that

[NSString stringWithContentsOfURL:encoding:error:]

works with this but i do not know how to implement it with the code of this article could someone please show me an example how i could get this link to work with this app.

here is the reference code.

NSString *hostString = @"http://2push2.us/apress/apress.php";
NSString *nameString = @"2Push2Test";
NSString *argsString = @"%@?token=%@&cmd=reg&name=%@";
NSString *getURLString = [NSString stringWithFormat:argsString,hostString,tokenString,nameString];
NSString *registerResult = [NSString stringWithContentsOfURL:[NSURL URLWithString:getURLString]];

Thanks

try the following

NSURL *url = [NSURL URLWithString:getURLString];

NSError *error = nil;
NSString *registerResult = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:&error];

if (error) {
    NSLog(@"Failure: %@", [error localizedDescription]);
}
