            indexLabel.textColor = [UIColor whiteColor];
            indexLabel.text = @"Details:-";

            UIView *cellSeparator = [[UIView alloc] initWithFrame:CGRectMake(0,545, self.view.frame.size.width ,3)];
            cellSeparator.tag=1;
            [cellSeparator setAutoresizingMask:UIViewAutoresizingFlexibleLeftMargin |
             UIViewAutoresizingFlexibleRightMargin | 
             UIViewAutoresizingFlexibleWidth];       
            [cellSeparator setContentMode:UIViewContentModeTopLeft];    
            [cellSeparator setBackgroundColor:[UIColor whiteColor]];
            [self.view addSubview:cellSeparator];

You could write a method to remove all the subviews of the view and modify this code according to your need.

- (void)removeSubviewsOfView
{
    NSArray *subViews = [self.view subviews];
    for(UIView *view in subViews)
    {
        [view removeFromSuperview];
    }
}
