"The current quarter of CS193p (Spring 2011) is not on iTunesU and can only be taken by registered students of Stanford University." gently caress. Although the last time they did this was when they revamped the curriculum, so maybe they're including Xcode4 this time around. I'm fully expecting the next quarter CS193p to be on iTunes U. Meanwhile, the Winter 2010 course is still really really good.

Anode posted:Is there a good reason to do more than one quarter? (Honest question, not sarcasm!) Well before when it was just iPhone development, probably not. But they've since updated the curriculum a few times, once to generalize on iOS+iPad rather than iPhone, and now I assume to add Xcode4. If you already know your stuff, absolutely not. Not unless you want a refresher. If you're just starting out or don't know Cocoa/ObjC very well? Probably can't hurt. Like I was pretty decent at it until I put it all on the backburner to work on my CCNA. I went through the iOS one and it really helped me re-learn some fundamentals. I guess you could argue that if I forgot them that quickly then I wasn't really that good to begin with, so whatever

By all means have him call Apple. Mine was hung up because apparently they don't accept a legally registered Ontario "sole proprietorship" as a business entity, but didn't actually tell me and I had to finally just call some number I found on the developer site and got the straight dope. If you are a verifiable contact point for your company they should at least be able to tell you what is being held up. Wish they had made the "sole proprietorship isn't valid for a corporate enrollment" thing clearer before I blew like a hundred bucks registering everything with the loving province though.

Go to the hackintosh thread in SH/SC or go read up on builds at the tonymacx86.com forum (better option). I would recommend waiting until Lion is out and not under NDA so you can get the best hardware for that particular platform since it's likely that all new Xcodes will require it at some point.

Looks like ObjC/CocoaTouch is a use-it-or-lose-it thing for me, so I'm going back to square one with CS193p and various books. I'm current on both XCode and MacOS X. Will I need to worry about things like ARC getting in my way if I start a brand new project today, or will they be transparent as long as I use the old memory model of manually retaining and releasing? All of my material is pre Xcode4.2. I was hoping to wait until CS193p updated with an Xcode4 and hopefully new memory management model semester but I really want to start getting a handle on this skillset again, so I can't really afford to wait. I suppose if the new semester is on iTunes and starts up soon I won't be too heavily invested in the current semester that I can't just start over. e: Oh it looks like I won't need to worry about ARC in 4.1 anyway I guess. some kinda jackal fucked around with this message at 13:46 on Aug 22, 2011 |

Can't you target 4.2 by just not using 4.3+ features? Sorry if that's a dumb question, but I'm curious how people manage to build apps that can still run on 3.1 platforms if all they can get is the newest SDK.

Does anyone know of a way to get the iOS Device Simulator to open on the same screen as a fullscreen'd Xcode 4 window in Lion? It's annoying since Xcode is like the last window out of four fullscreen apps, and if I want to check out my debugger I either need to un-fullscreen Xcode or flip back and forth four pages between the simulator and xcode window

It's a really weird tumultuous time for someone learning to develop for IOS. Transitioning to Xcode 4 combined with things like ARC on the horizon have me worried that I'm going to get myself used to one method of memory management while another is just around the corner. I don't mean to imply that manual memory management is bad to know or anything, but it would be awesome if the book covered it as well, even as an afterthought. Really wish I'd just stuck with it a year ago instead of re-learning it all now

geera posted:Now that I'd like to get back in to it, all of my resources are out of date and I don't really know where to go for updated information. Well, resources are pretty much still the same now as they were then. The only thing that I struggled with at the beginning was converting Interface Builder skills to Xcode4, but that took a few hours really. It was more trouble in my mind than it was in practice, but it would be awesome if the next semester of CS193p was on iTunesU and included Xcode4 (it can't not, at this point), and ARC (probably won't, but a man can dream). For someone who's starting from nothing, though, it might be harder to work with Xcode4 given Xcode3 material. That's really the only reason I say it's tumultuous.

Does anyone know why Xcode4 Organizer would not show a device's console? I have an iPhone 3G running 3.1.3. It's listed as a device in Apple's portal page, marked as development enabled, etc. The only thing I can think of that it MIGHT be is that it's jailbroken, but it's basically been jailbroken since forever and worked fine in Xcode3. Device shows up green in organizer, I can get a lot of other info off it, take screenshots, etc. When I click on the Console button though, I get a blank screen. Very annoying. edit: My Jailbroken iPad has no problem displaying console, so I'm not sure what it could be.

Oh I probably don't, it's a clean install from the App Store with no extra bells or whistles. I'm trolling around the developer portal and it doesn't look like SDK3 is available any more? Honestly if I can't get console on it that's not really a huge problem as long as I can still debug and set 3.1.3 as a deployment target. I might set up a VM with 10.6 and an Xcode3 SDK3 installation (assuming I could find one) if I really get desperate I guess. Like I said, just annoying I just threw it out on the developer forums too, maybe someone at Apple can advise. It's kind of weird that I'd be able to do stuff like take screenshots without SDK3 but console wouldn't be available. some kinda jackal fucked around with this message at 14:31 on Aug 31, 2011 |

That seems a little far-reaching to me. I can understand them enforcing guidelines on the link back to their site, I'm okay with that, but telling me I can't use a Myriad font is a little over the line. What if Myriad is the best suited font for my email, flyer, website, etc.?

Right, that's the takewaway I'd love to get from it too, and I think that's what they mean, but in their wording they use the same "don't use Myriad" phrasing in the same way they list their more absolute "don't delete parts of the App Store logo" rules which are (I would imagine) much stricter. If I had to guess I would say Apple made it vague enough to sound scary on purpose. But I guess in the long run it's not that important.

Hey speaking of debug: I was working on a little commandline app to do some file processing the other day, and I was NSLog-ging some output. Whenever I hit cmd-R to run the app it was like 50/50 whether the debugger/output window would stay open after it finished. Is there any rhyme or reason when that little window stays open? It was quite annoying having to mouse up to the top of the screen to open that window after the tool quit a good half of the time. I hope I didn't just ask the stupidest question in the book, but it's got me stumped. I don't use xcode that often these days so --

Well I wasn't sure if there was any value in understanding memory management in (as) depth anymore. I've only gone through the first lecture so far and haven't seen whether he's going to bring up the concepts. For that matter, I'm not really sure how important it is to understand what happens behind the scenes anymore aside from "hang onto this" and "if nobody cares about X, we don't care either", so it's cool to hear from people who might have made the change to ARC and know their way around the language more than I do. It's kind of sad how "use it or lose it" programming is for me. I was fairly comfortable with ObjC and Cocoa Touch two years ago, now I'm back at the "drooling babby" stage Also I'm glad to hear Paul teaches with ARC enabled. I wasn't sure if that made the cutoff for this semester. e: Oh my god, this setting in Organizer that lets me use my iPad for development remotely -- does this mean I can debug wirelessly as well?

Is there any way to tell Xcode to insert opening braces on their own line? So -(blah)blah:(id)arg { } instead of -(blah)blah:(id)arg { } Don't know how much of a travesty that is, but it's how I've been accustomed to writing code and I think it's much more readable.

Thanks. Looks like it might be a pain when it would be easy to adjust to the new method so I might just try to live with it one of the simple solutions doesn't pan out. I came across a bunch of other stackoverflow solutions that were complex but somehow missed this one. e: Followup: Does Xcode not honour sender class definition when dragging an action from storyboard to an implementation? I just dragged one of my UIButtons to my implementation file, told it to use UIButton instead of id as the sender but when it generated code it still declared the sender as id.

Yeah I thought they were doing delta updates. I was pissed when I saw the two-point changelog and a 1.8gb download edit: Weren't some of the previous 4.x updates pushed out as deltas? I know I didn't download 2 gigs a pop every time.

Eh, I don't mind that. I was dicking around in Xcode when I started the update download. I don't want App Store to decide when I should run the update, especially if it's a 2gb download that could take some time. I mean if it was a delta update that was like 100mb then maybe I'd feel better about letting App Store automatically update the devtools right there and then.

This is going to be a really dumb question, but what's the deal with having to declare methods in order? Like if I create method one, and in method one I make a call to method two, but method two is physically located below method one in the source, Xcode will throw an error saying that method two isn't declared. I thought the compiler would be smart enough to parse the entire source for a declaration. This is something I'd expect from BASIC. Like I said, I'm sure this is babby's first question, but it seems weird for a compiler that smart to be tripped up by something like that, especially since it bulletproofs every other little thing I do.

Yeah, I when I used to "know" this stuff I remember placing most of my methods into the header file whether they were intended to be public or private, which I guess was probably a poor design decision. That's probably why I don't remember running into this problem. By class extension you mean the private interface declaration that I can add to the beginning of my .m?

Thanks for that link. I feel stupid asking such a dumb question but now I'm smarter for it so everyone wins  e: Also what's tripping me up is that dragging a target from storyboard to code doesn't declare it in the interface anymore. How does that work? I would have thought that would NEED to be a public method Looks like I have a LOT of reading to do.

Toady posted:I've barely played with storyboards, but if you're referring to target-action, "IBAction" is a design-time feature to let Interface Builder know which methods are actions. It has access to all your source code and doesn't need to follow the visibility rules of a compiler. Well, sort of. I'm surprised that a method which isn't declared in the public interface can be used as a target for an IBAction because in my understanding it's all done through performSelector: in the end anyway, isn't it? If that's the case wouldn't the selector need to be public? Obviously not because that's not how it happens today, but just one of the many things I have backwards in my head for one reason or another. I'm starting to figure this out, and I have something like two Apple docs on my to-do list which will probably explain exactly why I'm wrong. Part of me wonders how much easier this would be if I never learned this back in the day. Now I'm coming into it with bits and pieces of old information and it's tripping me up a little. Though seeing an app pop from Xcode to my iPad is loving swell and makes the trouble completely worthwhile e: I should add that dragging a target action from my storyboard IB to my INTERFACE file actually does what I was expecting, creates the public method declaration AND the corresponding method implementation. I'm just surprised that dragging a target action directly into my implementation doesn't do the same. some kinda jackal fucked around with this message at 19:23 on Nov 23, 2011 |
