iPhone developers seem to treat concurrency as a dark art, secret knowledge that only a select few can handle. The forums are full of responses frightening people about the complexity of multithreading, when there’s generally a simple solution that solves the problem. I don’t want to spend a lot of time talking about the low … Continue reading Multithreading and Concurrency On The iPhone, the easy way
So I come from a Flash background (I know, I know) and one of the things I really like about coding in AS3 is the event based system. AS3 allows custom events that bubble through the hierarchy of objects and only those objects listening to the event need respond. It’s very elegant solution that conforms … Continue reading NSNotificationCenter Tutorial
The next thing I’m going to go through is how to push a new view onto the stack when the user taps the annotation’s call out button. This is relatively straight forward with one annotation, but is a little bit more complicated when it comes to multiple annotations that have all been created dynamically. In … Continue reading Creating a Map Based Application on the iPhone Part 2
Things have been pretty quiet here on the blog over the last couple of weeks, mainly because I’ve been flat out working on some client iOS projects.

The problem with this creative was that the iPhone SDK doesn’t include a video … Continue reading Transparent Video On The iPhone, It Can Be Done… With Flash!
AVQueuePlayer allows you to queue up a “playlist” of videos which are then automatically played one after the other. You can also set up a Notification to listen for changes in the AVQueuePlayer’s AVPlayerItems and then build custom code to repeat, skip or add new video items to the queue. This tut follows on from … Continue reading Video On The iPhone Tutorial Part 4, using AVQueuePlayer to play a series of videos in sequence
I come from a Flash background and something I’m use to doing a lot of in Flash is creating video walls (playing several videos at the same time). There are a lot of situations where you might want to do this, say having multiple video thumbnails playing, or a main video with another “talking head” … Continue reading Video On The iPhone Tutorial Part 3, playing multiple videos simultaneously
