UIActivityIndicatorView *indicator = [[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
indicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge;
[indicator sizeToFit];
indicator.autoresizingMask = (UIViewAutoresizingFlexibleLeftMargin |
UIViewAutoresizingFlexibleRightMargin |
UIViewAutoresizingFlexibleTopMargin |
UIViewAutoresizingFlexibleBottomMargin);
indicator.tag = 1;
[self.view addSubview:indicator];
[indicator setBackgroundColor:[UIColor clearColor]];
indicator.center = self.view.center;
indicator.hidden = FALSE;
[indicator startAnimating];
