    Transcript
    PETE: I can’t believe I beat Ben Scheirman today.

    CHUCK: With a stick?

    PETE: No, he’s in the wrong state for that.

    CHUCK: Hey everybody and welcome to episode 37 of the iPhreaks Show. This week on our panel we have Jaim Zuber.

    JAIM: Hello from Minneapolis, where it’s a balmy 4°.

    CHUCK: Pete Hodgson.

    PETE: You just totally stole my thunder. I was going to complain about being cold in San Francisco, but it’s a lot warmer than that. Hello from not-so-frigid San Francisco.

    CHUCK: How cold is it in San Francisco?

    PETE: [Chuckles] Like, 32°. I don’t know, it feels like it’s freezing, but it’s probably not even 32°. Probably warmer than that, just cold for San Francisco.

    CHUCK: Charles Max Wood from DevChat.tv and it’s also 4° here.

    PETE: Okay, I’ll stop complaining.

    JAIM: Really? Or is it just dry cold?

    CHUCK: Yeah, it’s just dry cold here, too. We did get some snow.

    JAIM: There we go.

    PETE: It all makes sense now.

    JAIM: A little bit nicer.

    CHUCK: Yeah. Gives you something to do – go shovel snow, go skiing – we’re making people jealous now, I'm sure.

    PETE: I think I've been here once in San Francisco when it snowed, and it was like two or three flakes on the top of Twin Peaks, which is like the only really tall bit of San Francisco, and people drove their cars up there in the middle of the night to see these snowflakes fall [chuckles]. But it wasn’t like snowball fights; it was like four snowflakes. It was really exciting; it made my year. No skiing that year for us at San Francisco.

    CHUCK: Oh, come on. Alright. Anyway, so today on our [inaudible] we have MVC.

    JAIM: Alright, we’re talking MVC – an MVC extravaganza of sorts, I think.

    CHUCK: Yup. [Chuckles]

    PETE: Maybe we should start off with a definition.

    CHUCK: [Chuckles] A definition. Thanks, Josh.

    JAIM: That might take the entire episode, I think.

    PETE: With MVC, I always get really confused. So I know what MVC stands for: Model-View-Controller. And I kind of understand the principles quite well. But what I don’t get is the difference between MVC and MVP, and then it gets really confusing when you start talking about some of the other things out there. This is a long shot. Do either of you two know the difference between MVC and MVP? Because I definitely could not answer that if I have to save my life.

    CHUCK: I have a very vague idea of what it means, so I'm not even going to venture to try because I’ll probably get it wrong. One thing that I can say, though is that I've come to iOS programming from a very strong Rails background, and MVC in Rails and MVC in iOS are not the same.

    JAIM: Yup.

    CHUCK: I tend to think of iOS as more of an MVVM, because –.

    JAIM: I forgot about that one.

    CHUCK: The controller acts more like a view model or a view controller than it does, you know, a full-on controller.
