code to download data from web server

[Shilpa]

I am tring to use NSURLRequest to access data stored in a database
hosted on web server.But the sample code for NSURLRequest mentioned in
the apple documentation specifies an instance method "receivedData". I
couldnot find much details about this.If anybody has an idea about
this please help?

Which sample code? Can you give me the snippet that confuses you?

This is the sample code for creating a connection:

// create the request

NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL
URLWithString:@"http://www.apple.com/"]

cachePolicy:NSURLRequestUseProtocolCachePolicy

timeoutInterval:60.0];

// create the connection with the request

// and start loading the data

NSURLConnection *theConnection=[[NSURLConnection alloc]
initWithRequest:theRequest delegate:self];

if (theConnection) {

// Create the NSMutableData that will hold

// the received data

// receivedData is declared as a method instance elsewhere

receivedData=[[NSMutableData data] retain];

} else {

// inform the user that the download could not be made

}


It is commented that "receivedData is declared as a method instance
elsewhere". This part is not clear to me.

I would assume that means the instance method is declared in the class
declaration.

Look for @interface
