Question

I have a tableview contains xml parsed objects.

I want to implement activity indicator in this tableview ,if the data loading is completed activity indicator stops automatically.

How to do this?.

First of all you need to make an async call to get your xml data.

Start your activity indicator before making the call then in the delegate method when you receive the data stop the activity indicator the code looks something like this.

- (void)getAsyncData
{
    // do something here......
    [indicator startAnimating];
    [NSURLConnection connectionWithRequest:urlRequest delegate:self];
}

#pragma mark -
#pragma mark NSURLConnection delegate
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
    [responseData appendData:data];
}

-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:responseData];
    xmlParser.delegate = self;
    [xmlParser parse];
    [xmlParser release];
    [indicator stopAnimating];
}
