I tried several different ways of presenting the tutorial, but I found that it seemed to flow better if I did all the coding first. Plus, in this particular situation most of the cool stuff happens in the code anyway.

excelent :)
thanks

Excellent tutorial! Thanks so much!!

This is a great tutorial, but I'm struggling with something. In my application I have several views which need to access the data. So in the "Add" view, entries can be added, in the "Show" view, entries can be shown and deleted. If the array is declared in the AppDelegate, how can that data be accessed by all of the views within the application?

Please disregard that comment - I'm a little slow! Excellent tutorial! :)

Hello Nick,
Thank you very much for the tutorials. It's very helpful.
The explanation are very well done.
Do you have a sample code or a tutorial using Tab Bar mixed with Navigation Controllers?
Thanks,
André

I don't have any sample code, but what you're asking about is rather easy once you understand how tab bar controllers and nav controllers work. I haven't done any tutorials in a while, but I've been getting a lot of emails and questions lately so it may be time to get some more ready. With Thanksgiving coming up, it may be a week or two before the next tutorial shows up....just know that there are some more coming.

Hello Nick,

nice Tutorial. Helped me alot to understand how to save userdata. I just tried the leaks instruments provided by xcode and realized that there is a memory leak in the code. The memory leak comes from the init method in the delegate class. I just don't understand why.

Thanks,
Trung

Edit: Sorry, this just happens on the simulator, not on the device.

Very useful & Save me a lot of time.
Thanks ^_^

@Trung Tran: I have an app that's available in the app store right now that had memory leaks when I tested it with Instruments. However, the program was leaking a data type that I didn't specifically declare, so I went ahead and submitted it and it got approved. My advice would be to make sure that your program isn't leaking anything you're directly responsible for. I chalk anything else up to buggy software (on Apple's part, not yours).

Really nice, thank you :)

Good video. I am new to iPhone programming. I noticed the comments are at least 1 yr old- is the code in this video still current best practice or has Apple changed or deprecated any code in it?
