[y-o-r-g-u-n]

hey i'm new in objective c and i have a problem. i have a program and in it there is a button and when i click that button a date picker appears. i choose date from it and i click ok button. when it returns previous view i want to write that day on a label.but i can not access that label. and the codes are here, please tell me what i'm doing wrong.

-(IBAction) donebutton{
appDelegate = (iFly_ticketAppDelegate *)[[UIApplication sharedApplication]
delegate];

//Use NSDateFormatter to write out the date in a friendly format
NSDateFormatter *dateFormatter= [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd"];

NSString *dateString =[NSString stringWithFormat:@"%@", [dateFormatter stringFromDate: datePicker1.date]];
appDelegate.dateString = [NSString stringWithFormat:@"%@", dateString];
[dateFormatter setDateFormat:@"dd.MM.yyyy"];

NSString *dateString1 = [NSString stringWithFormat:@"%@", [dateFormatter stringFromDate:datePicker1.date]];
appDelegate.visibleDate = [NSString stringWithFormat:@"%@", dateString1];
[dateFormatter setDateFormat:@"EEEE"];

NSString *dayOfWeek = [NSString stringWithFormat:@"%@", [dateFormatter stringFromDate:datePicker1.date]];

iFly_ticketViewController* rw = [[[iFly_ticketViewController alloc] init] autorelease] ;

rw = (iFly_ticketViewController*)[appDelegate.navigationController.viewControllers objectAtIndex: 0 ];
if ([rw.nibName isEqualToString:@"iFly_ticketViewController"]) {
[rw.goingdatelabel setText:[NSString stringWithFormat:@"%@ - %@", dateString1, dayOfWeek]];
[dateFormatter release];

[self hideModal:self.view];
iFly_ticketViewController *tController = [[[iFly_ticketViewController alloc] init] autorelease];
tController = (iFly_ticketViewController*)[appDelegate.navigationController.viewControllers objectAtIndex[appDelegate.navigationController.viewControllers count]-1)];
[tController.view setUserInteractionEnabled:YES];
[tController.navigationController.view setUserInteractionEnabled:YES];



[dateFormatter release];
}
}

Use NSNotificationCenter thats your answer for stuff like that.

thanks a lot i solve the problem but this time i have another problem in my program.

i wanna connect a xml document and i wanna parse it and then write the returning result in a picker view. i use nsxmlparser and i connect the xml file but i cant parse and write it. i send the xml two parameters which are one of them is username and password and the other is process that needs to be return. and this parameters are in xml format like <Kalkis><Ulke></Ulke></Kalkis>
and the returning answer is an xml too.
when i wrote the returning xml in console i get this xml contains error message

<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><XmlIsletResponse xmlns="http://tempuri.org/"><XmlIsletResult><IslemSonuc xmlns=""><Sonuc>false</Sonuc><Hata>Gönderdiğiniz XML Biçimi Uygun Formatda Değil</Hata></IslemSonuc></XmlIsletResult></XmlIsletResponse></soap:Body></soap:Envelope>

why the result contains error? i work hard to solve it but i cant. thank you in advance.

This should be in a new thread. Sounds like your request is not formatted properly and the server is telling you that.

well how can i solve this problem. i dont know what is the xml page's format. i've been told use the soap message which i added below.

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<XmlIslet xmlns="http://tempuri.org/">
<xmlIslem>xml</xmlIslem>
<xmlYetki>xml</xmlYetki>
</XmlIslet>
</soap:Body>
</soap:Envelope>

i really dont know what's wrong with that? i totally stuck and i dont know what to do.

Well, you'll have to show us your code for formatting the request.

Also, please use CODE tags (the hash mark on the toolbar) for code blocks, not QUOTE tags. Only CODE tags will result in properly formatted code blocks.
