Answer 1

So u want to use the UIActivityIndicator while accessing the server.
First create the indicator while the connection call, and when connection didfinishloading remove the activity indicator
//call this when connection start
UIActivityIndicator *activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
activityIndicator.frame = CGRectMake(140, 236, 37, 37);
[activityIndicator startAnimating];
[self.view addSubview:activityIndicator];
self.view.userInteractionEnabled = NO;
//remove activity indicator while connection did finish loadin
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[activityIndicator stopAnimating];
[activityIndicator removeFromSuperview];
self.view.userInteractionEnabled = YES;
}

First of all add Activity indicator in xib and connect object of the UIActivity Indicator.
Click "Hides when Stopped" in the xib.
Then,
-(void)FetchFromServer
{
NSURLRequest* updateRequest = [NSURLRequest requestWithURL: [NSURL URLWithString:#"Write Your Url Here"]];
NSURLConnection* connection = [[NSURLConnection alloc] initWithRequest:updateRequest delegate:self];
[connection start];
[activityIndicator startAnimating];
}
And then in the delegate,
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
UIImage *img = [UIImage imageWithData: data];
myImageView.image=img;
[activityIndicator stopAnimating];
}
