My web service is quite database-heavy (using PHP and mySQL), resulting in the user being faced with a blank screen for several seconds.
When a user clicks a link on an HTML page, a javascript function is triggered, which then initiates an AJAX call to invoke a PHP script before returning.
I am interested in implementing an IOS-like Activity Indicator, maybe as a "subview," to provide the user with visual feedback that something is occurring.
Any assistance on this matter would be greatly appreciated.
