Why is the tabBar still black even after I set opaque to NO, alpha to 0, and color to clear?

As above, I can't seem to change the background color or image of the tabBar. Even when hiding it by changing alphan 0, I still see it as a black solid bar.
There is nothing behind the tab bar. The views of the view controllers that tab bar controllers manage do not extend into the area occupied by the tab bar.
I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...
Try this piece of code:
ReplyDelete[tabBar setHidden:YES];
If you're trying to set an image for the background, try this:
[tabBar setBackgroundImage:myImage];
