UIActivityIndicatorView* progressInd = [[UIActivityIndicatorViewalloc]init];

progressInd.frame = self.bounds;  

progressInd.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge;

        //[progressInd setColor:[UIColor colorWithRed:234.0/255.0 green:90.0/255.0 blue:90.0/255.0 alpha:1]];

[progressIndsetColor:[UIColorlightGrayColor]];

[selfaddSubview:progressInd];

[progressIndstartAnimating];
