Android developer moving to iOS - What do I need to know?

I'm interested in starting developing on the iOS platform, after a couple of years of Android work. What are the main things that are likely to trip me up when designing/coding for iOS instead of Android?

    I have done some iphone apps after doing Android.


    Objective-c is just another language; not at all hard to learn.
    Understand how iPhone memory works. How the ref count and AutoreleasePools stack works. This should be the most important thing to learn.
    You will love the interface builder. Creating a new screen for the iPhone is much easier.
    iPhone's version of the Android ListView is called a TableView. More or less the same but you need to define an amount of sections.
    I love how iPhone devs use the Delegate pattern, I am using it in Android now. Pay attention to that.
    Resources can have their own folders. For example: A drawable can be in /car/model/drawable
    Adding animation to iphone objects is VERY easy. You will notice that a lot of methods have a last parameter with BOOL animated.
    Creating custom components is easier.


    Things that made me lose a lot of time:


    You can send msgs to NIL.
    Logs are not as friendly as Android's.
    You need to add every file to the project. It's not just putting it in the correct place.
    Updates to the env means downloading 2GB every time.
    When printing logs with NSLog, NSString needs to use %@ not %s.
    Xcode has some strange behavior. The cursor moves around your screen.
    Merging commits in iPhone source is hard. The project file and the xibs always get conflicts.

    I just want to say that Dont use Interface Builder, Try to make application through coding
    with this you will easily catch the building process for IPhone program.

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.
