CGameProgrammer posted:So it's possible to buy and install Mac OSX without a Mac? Yes. It's possible to install in VMWare, and it is also possible to install on regular PC hardware (if you use the right components). Both of these things are not exactly...legit. And involve using community 'tools' to boot using an unedited OSX image or hacked versions of the OSX image. CGameProgrammer posted:...another question: how do you test applications that use accelerometers, or the camera, etc? It sounds like you have to deploy them onto the target hardware, but how do you do that without going through the App Store (which is obviously only for finished and released products)? XCode can deploy to a device as long as you setup a provisioning profile for that device, which can be done in the Apple developer member area. You can also deploy to devices using things like TestFlight, but you still need to setup provisioning profiles. The provisioning profiles you get this way are temporary and for development / testing purposes only. xgalaxy fucked around with this message at 20:03 on Apr 14, 2012 |

It looks like that Learning Core Audio book has finally been released. I've read a good amount of the in-progress version and it seems very good. I wish it had been out when I had first started learning Core Audio, but I think there's still a lot I can learn from it.

So I am somebody with essentially no experience who is teaching myself to program, and I have a question that is probably stupid. I am a college student, and the online system to register for courses here is pretty poo poo. I feel like I could dramatically improve the user interface, but I'm not sure how possible that is. So my question is, would it be at all possible to make an app that would interact with the existing web site by automatically submitting forms and clicking links so that I could arrange the data in a non-retarded format without actually having access to the backend? Like I said, I'm still pretty much teaching myself at this point, so I'm just trying to figure out if it's even possible so that I don't devote a bunch of time and effort to trying to figure out how to do it if it's not.

It is definitely technically possible. Your app will need to emulate the requests that would be made via the normal web interface, including whatever authentication the registration site uses. This may be straightforward or an obnoxious reverse-engineering effort, depending on how the system's been engineered. You have a major advantage, though, in that web technologies are pretty hard to obfuscate. The first place to start is to capture the HTML and Javascript used by the registration page and try to understand everything it's doing and how it interacts with the server. That can be a really good lesson in and of itself. \/ Oh, and that, of course. As an unofficial client of the registration servers, the admins will have no compunctions at all about breaking you. rjmccall fucked around with this message at 07:39 on Apr 15, 2012 |

Definitely possible and, assuming your app works at all, it'll get some solid use too. Why does every school with a CS department have a terrible website? Anyway, your app will break down into three parts: 1. Scraping your school website HTML for data (tip: View > View Source in your browser) and submitting forms (ditto). 2. Persisting and modifying that data within the app. 3. Your app's user interface. You'll want to use something like AFNetworking to do the network requests/responses and libxml for scraping (with a little wrapper like the one from DTCoreText (grab the linked file and its .m counterpart, don't need the rest)). That'll get you started actually talking to your school website. If you're new to all this, expect to take a good few hours to a couple days to get to this point, and ask for help whenever you need it. Once you're there, it's up to you whether you implement all the functionality you'll need in the backend (filling out each form, scraping each unique page) or stub out the interface and make the buttons and tables start working. Or start both and meet in the middle. Feel free to ask anything here. No question is too small, so long as you've tried to solve it yourself first.

All right, thanks for the responses guys. As somebody who is learning to program by watching lectures on iTunes, I'm pretty far removed from that for the time being, but I'm sure I'll be back with more questions once I get to that point (this will probably be a summer project). It seemed like a decent idea for a practice project just because so much of the structure was already in place, and also because it's something I and others would get a good bit of use out of. Of course, I'm still figuring this stuff out, so it's entirely possible that this is way more ambitious than I had originally thought, but I just wanted to check in and make sure it was possible first.

It's probably good I didn't see this yesterday: I spent an hour and a half googling, trying to figure out why my TableView embedded in a custom view wasn't scrolling (but could take interaction -- clicking worked, so it wasn't an issue of user interaction not being set. Turns out I was using ipad controls on my mac's touchpad, trying to two-finger scroll. Which of course doesn't work in the iOS simulator, it wants a click and drag. I discovered my mistake when I accidentally used the wrong gesture to switch back to a browser for another round of fruitless searching. iOS simulator: 1. Kyth: 0.

if you want to allow the user to download levels for a game, is there a standard method for that? I'm thinking of using zip files with graphics & xml files and then unzipping them after download. Does that sound OK (as long as my naming convention is rock solid)?

One reason you may want to unzip them is to provide better minimal updates, say to fix a bug with one of the assets. This way you don't have to get the entire contents of the zip again, if you are only fixing a single asset. Pick a strategy that works best for the kind of data you have.

Why is it so insanely complicated to just make a loving 'Hello World' view that has a UIButton that simply shows another view? Of course, if you choose a tabbed project you have that functionality out of the box, but that's not the point. This poo poo is a CHAPTER in a book.

Anybody got any ideas on why some object files are getting compiled with thumb assembly even when I tell the compiler not to compile thumb? I've tried -mno-thumb and -marm and neither one is stopping the generation of thumb assembly in the resulting binary. I've tried both llvm-gcc and clang. And both are doing this. Clang 3.1 coincidentally does not recognize either switch btw, a bug? Nothing in the project is inline assembly, and I've looked at the compile switches for the object files and I don't see anything wrong. The files, btw, are all libtom* related, and as far as I can tell only these particular object files are getting compiled thumb. otool shows every other object file as arm as requested. I'm pulling my hair out trying to figure out wtf... xgalaxy fucked around with this message at 07:41 on Apr 17, 2012 |

Clang has recognized both of those switches for years. If you're getting warnings about it, it's probably because the flag's being passed to the wrong command (e.g. to the linker). If so, it's innocuous, and it's not a problem as long as the actual compile line has it as well. Are you adding these as CFLAGS? I'm pretty sure there's some specific option to disable thumb, and I wouldn't be surprised if your flag is getting overridden by that; the last relevant option on a line usually wins. I'd need to see an actual command line to diagnose it further.

Cocos2D iOS: I'm having trouble accessing a parent method from a sprite class. A bunch of the sprite classes are put into a mutable array in the parent class. When a method is called in the child class a sort of timed call to the parent is called later on using CCCallFuncO. But even with a regular method call in the child class to parent won't work!

Stick a breakpoint on the line where you send -displayMessageBox: and check things out. Is joinedMapsLayer right object (i.e. not nil, right type)? Step into the method call. Does it go where you want?

Check and see if self.parent is nil. If you're adding the child sprites to the array yourself, rather than using CCNode's addChild: method, then you'll have to set the child sprite's parent property yourself.

Not to be a jerk, but if the parent property wasn't set somewhere then yeah, it isn't going to work. Also, is JoinedMapsLayer a descendent of CCNode? (if it's a descendent of CCLayer then it is). If so, you shouldn't need to make your own mutable array of sprites; each CCNode has its own array of all its children. Just do [joinedMapsLayer addChild:someSprite] or something and it will add it to joinedMapsLayer's CCArray and set someSprite's parent to joinedMapsLayer. And when joinedMapsLayer is drawn all its children will be drawn, etc. Inside your joinedMapsLayer code you can access the child objects by accessing the children property. Check out the documentation for CCNode (1.1 here, 2.0 here) and for CCArray (1.1 here 2.0 here).
