Is the ASIHTTPRequest is not asynchronous? - iphone

Question

I am using ASIHTTPRequest to fetch some data from a web service.
I am making requests using a loop.
The problem is that it doesn't seem the request is going asynchronously so that my activityindicator is not working .
Is it true that ASIHTTPRequest is not asynchronous .
or should i use the regular nsmutablerequest to perform asynchronous request .

Answer 1

You should put your request in a download queue, i.e.
ASIHTTPRequest *request = [[ASIHTTPRequest alloc] initWithURL:url];
[request setDelegate:self];
[request setDidFinishSelector:#selector(requestDone:)];
[request setDidFailSelector:#selector(requestWentWrong:)];
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
[queue addOperation:request];
[request release];
Just
[request startAsynchronous];
runs the request on the UI thread, so you should try it with download queue.

Answer 2

For Sync Synchronous
NSURL *url = [NSURL URLWithString:#"http://allseeing-i.com"];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request startSynchronous];
NSError *error = [request error];
if (!error) {
NSString *response = [request responseString];
}
Creating an asynchronous request
- (IBAction)grabURLInBackground:(id)sender
{
NSURL *url = [NSURL URLWithString:#"http://allseeing-i.com"];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDelegate:self];
[request startAsynchronous];
}
- (void)requestFinished:(ASIHTTPRequest *)request
{
// Use when fetching text data
NSString *responseString = [request responseString];
// Use when fetching binary data
NSData *responseData = [request responseData];
}
- (void)requestFailed:(ASIHTTPRequest *)request
{
NSError *error = [request error];
}
And there is lot of more options like Queue and many more
