iPhone autoresizingmasks

Image
By User



I've been experiencing problems with designing views so that the subviews behave the way I want when using autoresizingmasks (for example, if the status bar size changes, when using the phone as a hotspot etc.). Is there any good documentation that I should definitely read? Apple documents don't seem to help me at least not without some heavy testing of my own.

    Setting the autoresizingMask to UIViewAutoresizingFlexibleWidth, is equivalent to setting the width spring, plus both the left and right struts in Interface Builder (the struts mean that the edge is not flexible). If you wanted to replicate the behavior of only setting the width spring, but not the left and right struts, you would have to set autoresizingMask to UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin

    In Interface Builder on tap "Size inspector" you can choose autoresize mask you want. Also in little square screen it will animation with using autoresize so you can see what option did you set.

    This is the kind of thing that can be a bit complicated to figure out from docs and trial-and-error, but once you get it you'll wonder why you found it so confusing in the first place. I would:


    Read Handling Layout Changes Automatically Using Autoresizing Rules from the View Programming Guide.
    Play with the springs and struts in the Size inspector in Interface Builder. Putting a horizontal spring inside the box is equivalent to setting UIViewAutoresizingFlexibleWidth (and similarly for height). Putting a strut on top of the box is equivalent to turning UIViewAutoresizingFlexibleTopMargin off (and similarly for the bottom, left, and right margins).

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

By User
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

By User
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.
