downloading using NSURLConnection not downloading anything?

i am using NSURLConnection to download mp3 data from the server , my code is here 

- (IBAction)downloadData:(id)sender
 {

   NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
   NSURL *url = [[NSURL alloc] initWithString:@"http://viadj.viastreaming.net/start/psalmsmedia/ondemand/Nin%20snehamethrayo.mp3"];

   [request setURL:url];
   [url release];
   url = nil;

   NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];


 }

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response 
 {
     responseData = [[NSMutableData alloc] init];
 }

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data 
 {
   [responseData appendData:data];
 }

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error 
 {
  [responseData release];
  [connection release];

 }

- (void)connectionDidFinishLoading:(NSURLConnection *)connection 
 {

  NSLog(@"Succeeded! Received %d bytes of data",[responseData
                                               length]);
  NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *fileName = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"myFile"];

  [responseData writeToFile:fileName atomically:YES];

  responseData = nil;
  self->imageConnection = nil;


  }

am little bit confused about the path given to download. when i click download button i shows "Succeeded! Received 1329 bytes of data" but nothing is downloading. need some help. how will we specify the local path of iPhone to store downloaded data?

No need for any code change I think.Just put an nslog and see...

NSString *fileName = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"myFile"];
NSLog(@"%@",fileName);

That will list the file location like this /Users/me/Library/Application Support/iPhone Simulator/5.0/Applications/(your app)/Documents/myFile. ie the downloaded file is in your document folder.

note: don't forget to put the file format ie 

NSString *fileName = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"myFile.mp3"];

  NSMutableURLRequest   *theRequest_to = [NSMutableURLRequest requestWithURL:url];

}

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse*)response
{
  NSString *filepath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"snehamethrayo.mp3"]; // here you can set your filename which you can get from url 
  [[NSFileManager defaultManager] createFileAtPath:filepath contents:nil attributes:nil];
  file = [[NSFileHandle fileHandleForUpdatingAtPath:filepath] retain];// Here file is object of NSFileHandle and its declare in .h File
  [file seekToEndOfFile];
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
  [file seekToEndOfFile];
  [file writeData:data];
}


- (void)connectionDidFinishLoading:(NSURLConnection*)connection 
{
 [file closeFile];
}
