Create UIActionSheet "otherButtons" by passing in array, not varlist



I have an array of strings that I want to use for button titles on a UIActionSheet. Unfortunately, the otherButtonTitles: argument in the method invocation takes a variable length list of strings, not an array.





So how I can I pass these titles into the UIActionSheet? The workaround I've seen suggested is to pass nil into otherButtonTitles:, then specify the button titles individually by using addButtonWithTitle:. But this has the problem of moving the "Cancel" button to the first position on the UIActionSheet rather than the last; I want it to be the last one.





Is there a way to 1) pass an array in lieu of a variable list of strings, or alternatively 2) move the cancel button to the bottom of the UIActionSheet?





Thanks.

  1. I got this to work (you just need to, be ok with a regular button, and just add it after :

    NSArray *array = [[NSArray alloc] initWithObjects:
    [NSString stringWithString:@"1st Button"],
    [NSString stringWithString:@"2nd Button"],
    [NSString stringWithString:@"3rd Button"],
    [NSString stringWithString:@"4th Button"],
    nil];

    UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Title Here"
    delegate:self
    cancelButtonTitle:nil
    destructiveButtonTitle:nil
    otherButtonTitles:nil];

    for (int i = 0; i < 3; i++) {

    [actionSheet addButtonWithTitle:[array objectAtIndex:i]];

    }

    [actionSheet addButtonWithTitle:@"Cancel"];
    actionSheet.cancelButtonIndex = 4;

    [actionSheet showInView:self.view];

  2. One little note: [actionSheet addButtonWithTitle:] returns the index of that button, so to be safe and "clean" you can do this:

    actionSheet.cancelButtonIndex = [actionSheet addButtonWithTitle:@"Cancel"];

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.
