Connection

#1
NSURL *url = [NSURL URLWithString:[NSString
stringWithFormat:@\"http://maps.google.com/maps/geo?output=json&q=
%@” address, nil]];
NSString *data = [[NSString alloc] initWithContentsOfURL:url];

#2
[NSThread detachNewThreadSelector: @selector(getJSON)
toTarget:self withObject:nil];

#3
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:
[NSURL URLWithString: @”http://www.google.com” ]];
NSURLConnection *connection = [[NSURLConnection alloc]
initWithRequest:request delegate:self];
[connection release];
[request release];

NSURLConnection
- (void)connection:(NSURLConnection *)connection
didReceiveResponse:(NSURLResponse *)response;
- (void)connection:(NSURLConnection *)connection
didReceiveData:(NSData *)data;
- (void)connectionDidFinishLoading:(NSURLConnection
*)connection;

Problem
• Every initialized NSURLConnection shares
the same delegate methods, unless you
delegate to different objects.
• You could implement a class for holding all
those these, but you need to create a
object of that class for every download.
Not good.
