What is wrong with my NSURL statement? - ios

Question

Please glance at this and tell me why my NSURL *urlStringURL is alway an "invalid CRStringRef" Going blind trying to see what's wrong. Thanks!
EDIT: below code doesn't work since it's a GET. Can't encode the receipt to make a GET work. Good code follows bad code.
- (void) sendReceipt {
NSObject *rData = [[NSUserDefaults standardUserDefaults] objectForKey:#"purchaseReceipt"];
NSNumber *custData = [[NSUserDefaults standardUserDefaults] objectForKey:#"phoneNumber"];
NSString *urlString = [[NSString alloc] initWithString:#"https://www.privusmobile.info/Apple-???/?TYPE=GET"];
NSLog(#"Transaction to send %#,%#" , rData,custData);
urlString = [urlString stringByAppendingFormat:#"&Cust=IP%#", custData];
urlString = [urlString stringByAppendingFormat:#"&Receipt=%#", rData];
NSURL *urlStringURL =[NSURL URLWithString:[NSString stringWithFormat:#"%#",urlString]];
NSMutableURLRequest *urlRequest =[NSMutableURLRequest requestWithURL:urlStringURL];
NSString *params = [[NSString alloc]initWithString:urlString];
urlData = [[NSMutableData alloc]init];
[urlRequest setHTTPMethod:#"GET"];
[urlRequest setHTTPBody:[params dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES]];
NSURLConnection *connection = [NSURLConnection connectionWithRequest:urlRequest delegate:self];
connection = [[NSURLConnection alloc] initWithRequest:urlRequest delegate:self];
NSLog(#"started!");
}
END OF BAD CODE
The good code follows:
- (void) sendReceipt {
NSObject *rData = [[NSUserDefaults standardUserDefaults] objectForKey:#"purchaseReceipt"];
NSNumber *custData = [[NSUserDefaults standardUserDefaults] objectForKey:#"phoneNumber"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:#"https://www.privusmobile.info/Apple??????/default.aspx?"]];
[request setHTTPMethod:#"POST"];
[request setValue:#"text/xml" forHTTPHeaderField:#"Content-type"];
NSString *xmlString = [NSString stringWithFormat:#"<data><item>IP%# </item><item>%#</item></data>",custData,rData];
NSLog(#"XMLSTRING %#",xmlString);
[request setValue:[NSString stringWithFormat:#"%d",[xmlString length]] forHTTPHeaderField:#"Content-length"];
[request setHTTPBody:[xmlString dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];
NSLog(#"started! %#",connection);
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{
NSString * strResponse = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"SERVER DATA %#", strResponse);
}
The clue was the encoding hints. Thanks.

Try encoding the url string. Most likely there are spaces in rData but I'm just guessing. Try this:
NSObject *rData = [[NSUserDefaults standardUserDefaults] objectForKey:#"purchaseReceipt"];
NSNumber *custData = [[NSUserDefaults standardUserDefaults] objectForKey:#"phoneNumber"];
NSString *urlString = [[NSString alloc] initWithString:#"https://www.privusmobile.info/Apple-App/?TYPE=GET"];
urlString = [urlString stringByAppendingFormat:#"&Cust=IP%#", custData];
urlString = [urlString stringByAppendingFormat:#"&Receipt=%#", rData];
NSString* escapedUrlString =[urlString stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding];
NSURL *urlStringURL =[NSURL URLWithString:escapedUrlString];
