NSURLRequest/NSURLConnection not working? - iphone

Question

I got the code below to call a PHP script, for some reason it say that the connection is successful but it actually didn't call my script since I haven't received the email :-(
None of the NSURLConnectionDelegate methods get called.
Testing on iPhone 5.x device and Simulator.
Any suggestions/ideas? Thank you very much!
NSString* url = [NSString stringWithFormat:#"http://www.lenniedevilliers.net/mail.php?subject=%#&to=%#&body=%#", subjectLine, toAddress, emailBody ];
NSLog(#"web service URL: %#", url);
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString: url] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
connection = [[NSURLConnection alloc] initWithRequest: request delegate:self];
NSLog(#"connection: %#", [connection debugDescription]);
if (connection) {
NSLog(#"Connection succeeded");
} else {
NSLog(#"Connection failed");
}

NSString* url = [NSString stringWithFormat:#"http://www.lenniedevilliers.net/mail.php?subject=%#&to=%#&body=%#", subjectLine, toAddress, emailBody ];
NSLog(#"web service URL: %#", url);
//add the following or something like
[url setString:[url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString: url] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
//modify the following
connection = [[NSURLConnection alloc] initWithRequest: request delegate:self startImmediately:YES];
NSLog(#"connection: %#", [connection debugDescription]);
if (connection) {
NSLog(#"Connection succeeded");
} else {
NSLog(#"Connection failed");
}

I'd be willing to bet that you have some content in your email body that's not safe to send through the url
NSString* url = [NSString stringWithFormat:#"http://www.lenniedevilliers.net/mail.php?subject=%#&to=%#&body=%#", subjectLine, toAddress, emailBody ];
So say your email body contains &, that would break the code you have. You either need to escape the message body or send it through the request body instead of passing it through the URL. I could be wrong, but I bet that's what it is. Your code looks fine, I bet its the data ;)

Are you using the specific delegate functions for NSURLConnection?
- (void)connection:(NSURLConnection*)connection didReceiveResponse:(NSURLResponse *)response
{
NSLog(#"Did Receive Response %#", response);
responseData = [[NSMutableData alloc]init];
}
- (void)connection:(NSURLConnection*)connection didReceiveData:(NSData*)data
{
//NSLog(#"Did Receive Data %#", data);
[responseData appendData:data];
}
- (void)connection:(NSURLConnection*)connection didFailWithError:(NSError*)error
{
NSLog(#"Did Fail");
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSLog(#"Did Finish");
// Do something with responseData
}
