I was in Reading UK last week to attend the NSConference 2010. I will not write a full report of what happened there, because others will do that better.
The only thing I want to say is:if you want to improve your skills in Cocoa, for Mac, iPhone or iPad, you should go: you’ll have the best speakers, the best organization you can dream of. And you will come back with new contacts, new ideas, new code to try.
You can (should) read Alex Repty report here.
If, like me, you are tired seeing all these rumors about the absolutely freaking crazy product that Apple MAY announce tomorrow, and you are tired of reading about these rumors on absolutely every website in the world, I have a solution for you.
It’s a GreaseMonkey (and GreaseKit) script that will obliterate all mentions of the words « Tablet », « iSlate », « iPad », « iTablet » and replace them with « Unicorn », because more people have seen Unicorns than the famous iTablet.
Have you ever wanted to add an UIWebView to your application, so you can browse the internets without leaving your application? While it is a trivial task to add an UIWebView to a project, there are some links that an UIWebView will not handle.

There are different schools on how to start the design of an iPhone app. Some will prefer designing on paper (I do), others will use the computer to design their next breath-taking GUI.
So here is a list of some of the tools, template to design your next iPhone application.
For my current project, I have to rotate a CGImageRef by an arbitrary angle.
Here is the code:
I’ve not yet had the request to implement Push in an iPhone app, but a thread on the Developer Forums gave me a hint:
Some companies are already providing (or planning to provide) a gateway to the APN:
Let’s say you have an UITableView in which rows, when touched, changes the display to another view with an animation.
If you touch quickly a row, the row will highlight just before the animation starts.
The other day, I had to write a PHP script that reads a csv file of addresses and outputs the longitude and latitude of every address in the file.
Since I haven’t done a lot of PHP recently, I had to look in the documentation for the function that reads a file into an array because I couldn’t remember the name.
In my current project, I needed to know if a given NSDate was today, yesterday or earlier. Simple task, I thought. Until I looked at the documentation for NSCalendar, NSDateComponents and NSDate. While these are extremely powerful, I am not proud of the code I’ve written. It should be easier.
Anyway, the code below will take a date and return a formatted version relative from today:
