You are my teacher. Thank you for the tuts.

How about doing a short tut. about cocoa & sqlite using fmdb ?

That would be great.

Hi, can you create a tutorial about how to use the Source List control to change the views when you select an item on the source list just like the iTunes or several apps that have similar behavior?

Thanks

[MooSurfer]

Thank you for taking the time and effort to produce these excellent tutorials!

I have just started your tutorials and noticed when YOU create an app you don't have the ARC (Automatic reference counting) option. I understand ARC affects memory management so my question is, in following your tutorials if I have ARC selected, will this create errors in the coding because you will be allocating and de-allocating memory? Should I follow you tutorials without ARC selected?

Thank you.

@MooSurfer I'm going to have an intro to ARC video up under the Obj-C section today, so if you really want to know more you can check that out when it's up. For this specific tutorial it won't affect anything because we didn't really work with any code in this tutorial.

Hi Lucas,

awesome tut again :-)

I'm thinking about writing an application using a database actually instead of using core data because I need to have several user to be able to access the data at the same time.

I really would like to know how to connect to a postgesql or mysql database.

I'd love to see some hints about that. Thnx in advance and please keep on making these great tuts.

Best Kaneda

Very helpful

What is different in XCode 4.2 in building the tutorial?

[muggles92]

great videos, very helpful...w/core data and doc. based app, can I add some code(somewhere) to do some basic arithmetic on/to the entity..e.g.I have one column that shows a total expense which I would like to calculate from what the user has input in other columns e.g. for your player entity I could calculate age from the ' born' attribute ...thanks for your help

I Wish i could learn OBJC

[AppleProgramming]

@7ammoadel Why don't you? There are over 30 of them on the channel.

[clokverkorange]

@7ammoadel You can learn anything if you start at the beginning and don't give up.

Thank you, your tutorials are awesome!

I've tried to write a app, similar to candy bar, which replaces some system-files to change the layout of mac os x. Of course, I don't have the privileges to do that.

I've done some research, the only good way doing this is writing a helper app, which you run as root. Theres really NO tutorial, just the complex as hell documentation of apple.

Can you make a tutorial showing us how to do that?

That would really help me a lot! And I think, I'm not the only one, looking for a tutorial like this.

[AppleProgramming]

@MyOwnSongsAndCovers So you want to know how to work with the Security Framework?

[MyOwnSongsAndCovers]

@AppleProgramming Exactly! Maybe that sentence would have covered what I wanted to say :D

[AppleProgramming]

@MyOwnSongsAndCovers Haha, it's fine, there is very little info on that topic. I'll try to come up with a good example for it. Other people suggested that on the channel as well so we'll see ;)

[MyOwnSongsAndCovers]

@AppleProgramming Cool, thank you!

[zungaloca]

To easy

[AppleProgramming]

@zungaloca Glad you think so ;)
