I just fell in love with ARC. Made my day!

[AppleProgramming]

@RMH1565 Haha, yes it makes our lives that much easier.

[RMH1565]

@RMH1565 Does this change the way we use alloc? You said, that for example stringWithFormat would create an autoreleased NSString. What does this mean with ARC? Is it the old garbage collection or can I just use these instead of alloc?

[AppleProgramming]

@RMH1565 Nope, just use class method initializers or alloc init. Either way, ARC will understand how to release those objects later.

@oathcomrade Yep, I'll definitely have en example in the future, it's on the list of to-do's ;)

@AppleProgramming Will you cover "Core Data Entity Relationships" in the future? I would look forward to it!

[AppleProgramming]

@oathcomrade I just made 2 Core Data tutorials that you can probably figure out how to implement what you suggest from. They aren't too in depth but it may serve as a good starting block. What you suggest though may involve relationship which I haven't covered yet.

Hi AppleProgramming, yout tutorials are so helpful! Thanks! I have a question: Could you make a tutorial about coredata entities, how you can store an array in it? I try to have two tableviews where the first shows an an object and the second tableviewis depending on the first. Please could you help me?

@ernanimartins Thanks, computer science is definitely my path right now. I love teaching this stuff too so we'll see where it leads me.

@AppleProgramming Cool man! Many thanks for this info. If you aren't an apple employer already, you should be, if that is your focus, if not you could start a very nice startup with that knowledge in mind, based off on Mac and iPhone apps...:)
