Ok ! Coming to the point directly. What I want to do is explained as follows.

• I have an url of MP3 file. ( for example Sound File )
• Now, When user starts application.

• Download should start & for that I have implemented following methods.

  -(void)viewDidLoad {
  [super viewDidLoad];
  NSURL *url=[NSURL URLWithString:@"http://xyz.pqr.com/abc.mp3"];
  NSURLRequest *req=[NSURLRequest requestWithURL:url cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:120];
  
  
  NSURLConnection *con=[[NSURLConnection alloc] initWithRequest:req delegate:self startImmediately:YES];
  
  
  if(con){
      myWebData=[[NSMutableData data] retain];
      } else {
      //          [MainHandler performSelector:@selector(targetSelector:) withObject:nil];
    } 
  

  }

  -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { NSLog(@"%@",@"connection established"); [myWebData setLength: 0]; }

  -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { NSLog(@"%@",@"connection receiving data"); [myWebData appendData:data]; }

  -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { NSLog(@"%@",@"connection failed"); [connection release]; // [AlertViewHandler showAlertWithErrorMessage:@"Sorry, there is no network connection. Please check your network and try again."]; // [self parserDidEndDocument:nil]; }

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

• Now, Above methods work perfectly for downloading. But missing points are as follows.

  • I can not get the exact size which is going to be downloaded.

( means I want to know what is the size of file - which is going to be download )
