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()...

ReplyDeleteHere's what he said:
You can always set any font to those labels in code so if you want some guaranteed fixed values you'd better do that as size values may vary depending on many factors (cell's style, sdk version, os version etc).
I've tested on simulator with 4.2 SDK version and got following results (no extra properties were set for cells):
UITableViewCellStyleSubtitle:
textLabel: Helvetica Bold, size: labelFontSize+1 (18 px)
detailsLabel: Helvetica, size: systemFontSize (14 px)
UITableViewCellStyleValue1:
textLabel: Helvetica Bold, size: labelFontSize (17 px)
detailsLabel: Helvetica Bold, size: systemFontSize+1 (15 px)
UITableViewCellStyleValue2:
textLabel: Helvetica Bold, size: smallSystemFontSize (12 px)
detailsLabel: Helvetica, size: labelFontSize (17 px)
UITableViewCellStyleSubtitle font size
[UIFont boldSystemFontOfSize:17.0];
