Delete UITableViewCell and ALL of that cell"s data



I have a UITableViewCell. I can add and subtract 1 from the cell's textLabel and I can also delete the cells. Here is my problem, Lets say i add 5 to the value of the textLabel . And this cell is at the 0 indexPath (The First cell in the table). When I delete this cell and there are now no longer any cells on the table, I add a new cell and this new cell automatically gets the same value as the cell that was just deleted. SO this new cell will have a value of 5 and i want the cell to have a value of 1 just like every cell should when it is added. This only happens when a cell is deleted and a new cell is added at that exact same indexPath. So my question is: do i have to delete this cells "memory" or "data" for this to be fixed? Thanks a bunch for the help!





CellForRowAtIndexPath :







- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath

{

static NSString *CellIdentifier = @"Cell";



cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

if (cell == nil)

{

cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];

addBtn = [[UIButton alloc]init];

addBtn =[UIButton buttonWithType:UIButtonTypeRoundedRect];

[addBtn setFrame:CGRectMake(220,10,25,55)];

[addBtn addTarget:self action:@selector(addLabelText:) forControlEvents:UIControlEventTouchUpInside];

[addBtn setTitle:@"+" forState:UIControlStateNormal];

[addBtn setEnabled:YES];

[cell addSubview:addBtn];



subBtn = [[UIButton alloc]init];

subBtn=[UIButton buttonWithType:UIButtonTypeRoundedRect];

[subBtn setFrame:CGRectMake(260,10,25,55)];

[subBtn addTarget:self action:@selector(subtractLabelText:) forControlEvents:UIControlEventTouchUpInside];

[subBtn setTitle:@"-" forState:UIControlStateNormal];

[subBtn setEnabled:YES];

[cell addSubview:subBtn];



//cell.textLabel.text = @"1";





}

//cellText.hidden=!self.editing;

[cell setSelectionStyle:UITableViewCellSelectionStyleNone];

cell.imageView.image = [imageArray objectAtIndex:indexPath.row];

cell.textLabel.text = [number objectAtIndex:indexPath.row];





return cell;

}

  1. When cells are deleted or go off screen, the table view saves them and reuses them later. So you need to reset textLabel's value in tableView:cellForRowAtIndexPath:. The UITableViewCell class reference says this:


    The table view's delegate in tableView:cellForRowAtIndexPath: should always reset all content when reusing a cell.

Why is this Javascript much *slower* than its jQuery equivalent?

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()...

Is it possible to have IF statement in an Echo statement in PHP

Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
