NSMutableURLRequest and a Password with special Characters won't work

I'm writing a small program (using Cocoa Touch), which communicates with a webservice. The code for calling the webservice, is the following:

- (IBAction)send:(id)sender
{
    if ([number.text length] > 0)
    {
        [[UIApplication sharedApplication] beginIgnoringInteractionEvents];  
        [activityIndicator startAnimating];
        NSString *modded;
        modded = [self computeNumber];
        NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:      [NSURL URLWithString:@"https://tester:%=&[email protected]/RPC2"]];
        [theRequest setHTTPMethod:@"POST"];
        [theRequest addValue:@"text/xml" forHTTPHeaderField:@"content-type"];
        [theRequest setCachePolicy:NSURLCacheStorageNotAllowed];
        [theRequest setTimeoutInterval:5.0];
        NSString* pStr = [[NSString alloc] initWithFormat:@"<?xml version=\"1.0\" encoding=\"UTF-8\"?><methodCall><methodName>samurai.SessionInitiate</methodName><params><param><value><struct><member><name>LocalUri</name><value><string></string></value></member><member><name>RemoteUri</name><value><string>sip:%@@sipgate.net</string></value></member><member><name>TOS</name><value><string>text</string></value></member><member><name>Content</name><value><string>%@</string></value></member><member><name>Schedule</name><value><string></string></value></member></struct></value></param></params></methodCall>", modded, TextView.text];
        NSData* pBody = [pStr dataUsingEncoding:NSUTF8StringEncoding];
        [theRequest setHTTPBody:pBody];
        NSURLConnection *theConnection = [[NSURLConnection alloc]     initWithRequest:theRequest delegate:self];

        if (!theConnection)
        {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" 
                                                            message:@"A Connection could not be established!"
                                                           delegate:nil 
                                                  cancelButtonTitle:@"OK" 
                                                  otherButtonTitles: nil];
            [alert show];
            [alert release];
            sendButton.enabled = TRUE;
            return;
        }
        [pStr release];
        [pBody release];
    }
}

The Username and Password have to be in the URL, and it works in most cases, but when the password consists of special characters like in the example "%=&=-Test2009", the Webservice does not respond. If it is something like "Test2009" it works fine. Does anyone have an idea why, and maybe a solution for that?

You must use URL safe characters in your string when making the URL, use this NSString method stringByAddingPercentEscapesUsingEncoding: which will do this for you.

Special characters have to be URL encoded, the URL you requested,

https://tester:%=&[email protected]/RPC2

..is invalid, specifically the %= part (% is used for escaping characters, for example %20 is used to represent a space), so..

NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:
    [NSURL URLWithString:@"https://tester:%=&[email protected]/RPC2"]];

..should change to something like:

NSString *theAddress = [NSString stringWithFormat:@"https://%@:%@@%@",
                        [@"tester" stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding],
                        [@"%=&=-Test2009" stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding],
                        @"example.com"];

NSURL *theURL = [NSURL URLWithString:theAddress];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:theURL];

This requests the URL https://tester:%25=&[email protected]
