I've been slowly making my way through Aaron Hillegass' Cocoa Programming for Mac but unfortunately I've hit a roadblock. In chapter 12 you're supposed to modify an app you built in an earlier chapter to include a preference window, however I cannot for the life of me get mine to show up, and there's no logging or errors to give me any indication of what's going wrong. As far as I can tell I've followed the book (as best as I can given the XCode 3 -> 4 differences) but I just can't figure it out. I've thrown my entire project up at http://www.mediafire.com/?ddnyjx2wof6cia7 and I was hopeful one of you fine folk could tell me what's gone wrong. As you can see from the quality of the app I'm still very much just playing around and learning. Also, are there any books of a similar learning curve dedicated to XCode 4?

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

I have been given the task of making an app for the iPhone. Its not going to be too complicated and I already have Adobe Flash down so thought "this isn't too bad" and then apple announces its not allowing anything written in flash in the app store. poo poo. So does anyone have any good beginner tutorials for me to get to grips with XCode. Something really really simple to start with as I want to learn it and not just cut and paste some tutorial code and think I have achieved something. Alternatively is there any flash like tool that I can create the app in that Apple has decided is worthy of their store? I don't have $3000 to blow on Unity though.

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.

I used "Beginning iPhone 4 Development - Exploring the iOS SDK." It covers pretty much everything in a fairly basic level of detail, and the lessons are self-contained enough that you don't necessarily have to do every single one (though I would recommend doing all of the early ones, maybe up to chapter 7 or so).

For an example look at Amazon's recent Kindle HTML5 app they built. Of course, it may not feel like a native app and probably won't perform as well.

How unrealistic is this.... I have 6 Months to get an app to market. from what I know now, nothing. To a fully working app. I should explain that the client wants a professor leyton like murder mystery game, but with only 5 scenes or levels. I can do the artwork no problem and the story is sorted. Am I screwed? (in flash this would be a complicated but doable task)

They've rescinded that decision and you've been able to publish from Flash CS5 and up to iOS. I'd recommend going from CS5.5 though, as the AIR 2.7 runtime/packager provides some significant performance increases. That being said, learn Objective-C and the Cocoa framework anyway. It's not that confusing once you figure out the syntax and memory management principles. This will allow you to use all the APIs provided by Apple instead of being locked into what Adobe exposes in Actionscript.

The two books which really helped me grasp the language were: [Code] Big Nerd Ranch Guide - http://www.amazon.com/iOS-Programming-Ranch-Guide-Guides/dp/0321773772/ref=sr_1_2?ie=UTF8&qid=1314641984&sr=8-2. & [Theory] iOS 4 Programming -http://www.amazon.com/Programming-iOS-Fundamentals-iPhone-Development/dp/1449388434/ref=sr_1_1?ie=UTF8&qid=1314642033&sr=8-1 Big Nerd Ranch was great for writing out applications from start to finish and slowly introducing certain concepts, and iOS4 is light on sample and big on theory. Both are updated for Xcode 4.

The Big Nerd Ranch dude's hate of dot-notation is pretty dumb IMHO. In the iOS version he just calls it "confusing" but in the OS X version he he says it's stupid and silly. It comes across as just him not wanting to learn a new thing. Wonder what he'll think of ARC. Luckily everything else in the book is pretty good.

Is there a good way to determine the exact model iPad at compile time (1 or 2)? I need to change some things to optimize between the two, and I'd rather do it at compile time than runtime. If it needs to be runtime, is there a better solution than this StackOverflow answer?

I gotta say I've been going through the same transition and the way XCode 4 handles ARC and tells you off for using old-style memory management is really friendly, and will let you know if you're doing anything wrong. I switched a project over to ARC and all it really did was just point out all my retains, releases and deallocs etc and told me to get rid of them.

All I can say really is that Flash + XML on a mobile platform is just as fun as it sounds. Doesn't help that Flash Builder 4.5 itself is a buggy piece of poo poo. On the other hand, it's quick as hell to get a really basic app up and running.

I need to change some things to optimize between the two, and I'd rather do it at compile time than runtime. As Small White Dragon says, both iPads load and run the same code. They won't differentiate. I feel like you should actually ask your question about what you're trying to do. quote:If it needs to be runtime, is there a better solution than this StackOverflow answer? Sure: check for the presence of features you need, e.g. whether a camera is present, or some amount of video memory.

Small White Dragon posted:I believe they're both ARMv7, so you can't compile a universal binary with separate iPad 1 and 2 versions. And in reality, you should be checking against capabilities of the device instead of the type of device itself. Worst-case, check if the device has a camera and then do a UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad conditional. Not a proper solution but a helluva lot cleaner than the StackOverflow answer you posted.

I can't speak for anyone else, but this is normally a pretty helpful (and quick) thread, and I notice nobody's tried to help you out yet. Personally, I skipped over your query because "what's wrong?" is far too general a question. If you can do a bit more legwork in figuring out what's wrong (such as "I get this error message" or "I expect to see X when I do Y but I see Z instead", and/or narrow down which part of your project seems to have the problem, I'd feel more willing to help.

Re: iPad 1 vs. 2 check -- I'm writing an audio synthesis app that really pushes the processor to get every drop of power, and I've been developing on an iPad 2. I continue to optimize every ounce of performance out of my synthesis code, but I fear that I may need to make some cuts to the synthesis code itself to avoid sample dropping on the iPad 1. For example, I might need to drop the maximum voice polyphony. This would mean loading a lighter version of the synthesis graph. Checking for device capabilities is already done. But I'm anticipating a hit in the processor, and for that I would need to know which device it's running on. I'll be getting my hands on an iPad 1 within the next week or so. We'll see how bad it is...

For example, I might need to drop the maximum voice polyphony. This would mean loading a lighter version of the synthesis graph. Has your synthesis sub-system got any self-monitoring metrics in it? My personal framework dynamically alters the polyphony (or, to be precise, starts stealing voices allocated to older sustained notes) when the render code gets dangerously close to supplying the next 256 samples late. Thus it scales to the execution environment's capabilities without needing any device check and mostly avoids nasty drop outs even when running in the background or if the user is multi-tasking it with something that is greedy or spikey (e.g. notifications) with processor usage. Of course, this may not be an applicable solution for you depending on exactly how you've structured your synth architecture.

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 |

I don't have an effective way to dynamically allocate voices, and even if I did, for this project I'd rather have the consistency to say 'You have X number of voices available,' even if the number is a bit lower for the iPad 1. In other news, I'm so close to entering beta testing I can barely contain myself. drat the beginning of the school year!

I hear ya. 8 voices is a good choice for polyphonic synths as it allows 2 reasonable chords to be played in sequence without cutting off the release of the prior, and constantly rendering voices is great for free-running LFOs and similar timbral motion. Good luck with the beta and subsequent review and release! Are you also supporting CoreMIDI?
