Assigne tag to a each view and access the view with tag and put it 

+(void)removePregressIndicator:(UIView *)hideView;

{
      UIView *viewToRemove = [self.view viewWithTag:assigne_tag];
     [viewToRemove removeFromSuperview];
}

You can set a unique tag for the busyView like this busyView.tag = your unique tag;

And then you can remove the view with this code

+(void)removePregressIndicator:(UIView *)hideView;
{
    UIView *busyView = [hideView viewWithTag:your unique tag];
    if (busyView){
        [busyView removeFromSuperview];
    }
}

You should make sure that the busyView tag is unique for all the subviews of hideView.
