Я написал этот ответ на другой вопрос, но я думаю, что это поможет вам. В частности, обратите внимание на методы
-(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
и
-(void) connectionDidFinishLoading:(NSURLConnection *)connection
-(void) requestPage
{
NSString *urlString = @"http://the.page.you.want.com";
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLCacheStorageAllowed timeoutInterval:20.0f];
responseData = [[NSMutableData alloc] init];
connection = [[NSURLConnection connectionWithRequest:request delegate:self] retain];
delegate = target;
}
-(void) connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
if ([response isKindOfClass:[NSHTTPURLResponse class]])
{
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse*) response;
//If you need the response, you can use it here
}
}
-(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
{
if (connection == adCheckConnection)
{
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
//You've got all the data now
//Do something with your response string
[responseString release];
}
[responseData release];
[connection release];
}
