Blocks – An Interesting Objective-C Addition In iOS 4
Blocks are a feature of the C language that have been added to the iPhone and iPad sdk with iOS 4.
What they allow you to do are create usable “blocks” of code that you can pass along like any object. This probably sounds a lot like a function, and they are very similar, but there is a significant difference in that they “close” around variables that are in scope before a block is declared.

The Best Resources In iOS Development August 16th 2010 (For 2 Weeks July 31-Aug 13)
It continues to be an exciting time to develop on the iOS platform, and in the last couple of weeks some interesting news has come out.

UILabel Subclass – Align The Text How You Want!
I received a question in the last few days from an iPhone developer who was having difficulty aligning the text in a UILabel properly.

I found a subclass in an older thread on the apple forums here: http://discussions.apple.com/thread.jspa?threadID=1759957
Getting Your App Made Even If You’re Not A Programmer
If you have been struggling to learn iPhone and iPad development, or you want to develop an app — but don’t want to do any programming. You’re not alone.
I found this great article today that goes through how to get that iOS app done. The article goes into discovering what you as a non-programmer can bring to the table.
