ASIHTTPRequest - download problem - iphone

Question

I try to download a file from my server, this is the code, on my console I see the xml file, but I can't save it.
Where is the problem for you?
- (IBAction)grabURL:(id)sender{
NSURL *url = [NSURL URLWithString:#"http://www.endurodoc.net/photo/data.xml"];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request startSynchronous];
NSError *error = [request error];
if (!error) {
NSString *response = [request responseString];
NSLog(#"%#",response);
}
else{
NSLog(#"Errore");
}
//[request setDownloadDestinationPath:#"/Users/kikko/Desktop/data.xml"];
// SAVED PDF PATH
// Get the Document directory
NSString *documentDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
// Add your filename to the directory to create your saved pdf location
NSString *pdfLocation = [documentDirectory stringByAppendingPathComponent:#"data.xml"];
// TEMPORARY PDF PATH
// Get the Caches directory
NSString *cachesDirectory = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject];
// Add your filename to the directory to create your temp pdf location
NSString *tempPdfLocation = [cachesDirectory stringByAppendingPathComponent:#"data.xml"];
// Tell ASIHTTPRequest where to save things:
[request setTemporaryFileDownloadPath:tempPdfLocation];
[request setDownloadDestinationPath:pdfLocation];
}

Answer 1

You need to put:
[request setTemporaryFileDownloadPath:tempPdfLocation];
[request setDownloadDestinationPath:pdfLocation];
before:
[request startSynchronous];
ASIHTTPRequest does the file saving when the request is made, so if you set those properties after the request has already happened then nothing will happen.
