Can someone guide me how to download zip files from web?



If you're using <a href="http://developer.apple.com/library/ios/#documentation/cocoa/reference/foundation/Classes/NSURLConnection_Class/Reference/Reference.html" rel="nofollow">NSURLConnection</a>, it works exactly the same way no matter which type the file has.

<hr />

<strong>Example:</strong> (typed off of my head, no guarantee that it works this way and you should obviously implement error checking)

- (void) download { self.loadedData = [NSMutableData data]; // make 'loadedData' a property of the class NSURL *url = [NSURL URLWithString:@"http://..."]; NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:20.0]; [urlRequest setValue:@"Optional User Agent" forHTTPHeaderField:@"User-Agent"]; // shoot it off NSURLConnection *mainConnection = [NSURLConnection connectionWithRequest:urlRequest delegate:self]; if (nil == mainConnection) { NSLog(@"Could not create the NSURLConnection object"); } }

Then you must handle the incoming data in the delegate methods, e.g. to just save your data:

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

Take a look at the <strong>other delegate methods</strong> and implement them, you should deal with authentification challenges and fail responses. You can also for example set:

[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;

in connection:didReceiveResponse: and set it to NO again in connectionDidFinishLoading:.
