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()...

ReplyDeleteFollowing code is use for the water drop effect,
-(IBAction)btnActionTapped:(id)sender{
CATransition *animation=[CATransition animation];
[animation setDelegate:self];
[animation setDuration:1.75];
[animation setTimingFunction:UIViewAnimationCurveEaseInOut];
[animation setType:@"rippleEffect"];
[animation setFillMode:kCAFillModeRemoved];
animation.endProgress=0.99;
imgV.hidden=YES;
imgV2.hidden=NO;
[animation setRemovedOnCompletion:NO];
[self.view.layer addAnimation:animation forKey:nil];
}
This code may helping to you.
Happy codeing.
