It says right in the documentation for AVAudioPlayer, in the -prepareToPlay section:quote:Calling this method preloads buffers and acquires the audio hardware needed for playback, which minimizes the lag between calling the play method and the start of sound output. It most likely releases the buffers and audio resources after a short interval so as not to be a resource hog. The docs for the -play method state that it will call the -prepareToPlay method if the audio player isn't ready to play. AVAudioPlayer is meant for stuff where a little lag doesn't matter and there isn't much justification for holding onto the audio resources for an extended period of time, like short UI sounds or something.

That's exactly what I was using it for and hitching for a third of a second is not acceptable, it's very noticeable if there is any accompanying visual change.

For anyone that does Ad Hoc distribution builds: Where do you keep your provisioning profiles? We have our TC server set up and it has an old, outdated distribution profile on it because we're too lazy to have to VNC in and update it ourselves. So whenever we push out a new build number to TC, we have to manually upload the newest provisioning profile so that new devices that we've added will have correct permissions. (This is through Testflight) Do you keep it in source control, and whenever you add a device, simply download and update the profile? And then have your CI/Build process use the profile from the source? Doh004 fucked around with this message at 17:59 on Apr 3, 2013 |

Watching the Stanford class (if a bit behind), the guy's made reference to this before, and I'm just wondering what's up with this. Is it basically an AJAX thing, except instead of Javascript, it's your app? Like, with everything over HTTP and probably messages in XML of some sort? Or is it more involved than that? If I wanted to learn more about that sort of thing (writing an app that has a server), what classes should I be looking at?

I don't have any suggestions for classes, sorry. Maybe head to the Cocoa Literature List and search for "server" or "http"? I'm sure you'll find something useful. And there's nothing better than firing up Xcode, starting a new project, and trying to make sense of it!

NSURLRequest plus NSURLConnection if you want to do it yourself, otherwise, AFNetworking. Of course, if you simply want to download a file at a specific URL, you could just do something like Objective-C code:

OS X thing I can't get to work: I have a NSMenuItem with a custom subview, and I can't get the thing to highlight. Objective-C code:That, from the NSMenuDelegate, is called each time I mouseover a different NSMenuItem/NSView, but item is always null. I feel like I'm missing some really simple boolean somewhere, but all I can find on this are a few StackOverflow questions that have what looks like 1/3 the code I need. dustgun fucked around with this message at 03:52 on Apr 5, 2013 |

I'm wondering if someone here could give me a good idea of the work that would need to be done to have the following iOS application made. I have a site with a form that consist in one text area that's site to website.com/process.php afterwards. Is it possible to have an App that would consist of this form + possibility to take a picture and add it (I imagine this could be submitted as $_FILES?) that would also be submitted to that process.php file. Is that easily doable for someone who has little but no knowledge in Cocoa/Objective-C ? If so, any pointers as to where should I start to learn around that?

That's very simple to implement. You'll basically only need an interface + an action that sends (auth+)text+image to your url. Look into NSMutableURLRequest or a wrapper library.

Anyone know why my UIBarButtonItem's aren't actually changing their backgrounds when highlighted or selected? I'm calling the setBackgroundImage for the correct states in a subclassed UIBarButtonItem, but it's not actually changing it. I made sure the style is Plain, which explicitly states that it glows when touched. In the mean time I'm trying to recreate the UIBarButtonItem look with setting a UIButton as the custom view. However, I don't know how to recreate the bottom lighter border that shows up on the bottom of the button. It's like a gray thin line, if the rest of my border was black. Any ideas?

Double post, but we found out why: We had set the tint to blackColor, which means the highlighted/pressed state was no different from its default color. I guess the highlighting isn't smart enough to detect that it cannot go any darker and should instead go lighter.

Word of warning: You currently cannot add new devices to provisioning profiles via the web interface. If you hit "Generate" on an Ad-Hoc/Development certificate's page, it'll save it with no devices attached and no way to attach them again. The only recourse is to delete the profile and make a new one. So, don't: Yodzilla posted:Just start mashing buttons until it works.

The only issue is our tester guy(s) don't have Macs or use XCode, so we'd have to teach them how to use it and we'd also have some worries about maintaining the tests down the road with new people.

Anyone else experiencing a bunch of issues with the simulator not attaching to Xcode when debugging? The only way I can reliably connect to the simulator is by switching the debugger from LLDB to GDB.

I'm considering options for sending real-time updates from a server to an iOS client, and it's mostly down to WebSockets vs push notifications. My thinking is that push notifications aren't quite the right tool because 1) there's no real-time delivery guarantee and 2) I don't really need updates to be sent unless the app is actually open. HTTP polling is an option too but I figured with a short polling interval there's a lot more overhead compared to WebSockets which might cause more battery drain. Anyone have experience doing real-time updates?

I have a ragel file in my project, it works fine with a build rule and compiles etc. Debugging is a bit hard though: Although I can set breakpoints (if I change the filetype to for instance objc source), and it will stop and show me the ragel file at the right spot (and I can tell the stack is right by po-ing local variables in the debugger), it doesn't show the highlighted line so stepping through code is incredibly difficult since I have to keep track of it mentally. Anybody done a similar thing and got it to work?

gently caress me, never ever ever accept a speech recognition job people. No matter how good your engine is, the client will want it to be better And after a one month job slipping into three months due to this loving client refusing to pay and constantly going "Why can SIRI understand it then huh?" (Our tests have Opensphinx actually getting a better recognition rate, but whatever) I'm loving out. I'm throwing in the towel and leaving the industry because I cant take this poo poo no more.

Done that. Contractually the dude is supposed to have paid but at this stage I'm so loving broke I can't afford a lawyer to chase this drat thing to its conclusion. Heres the thing. He told me at one point "The app is boring". He didn't seem to accept that I followed his (Fairly detailed) spec to the *letter*, and just because the idea sucks doesn't mean he can just back out. Well after I made him realise that he suddenly started squabbling with the recognition quality. Heres the thing though, we did prototypes *before the project started* with the exact engine, and he accepted it as quality enough, and it was on that basis we proceeded (all in writing). So at this stage he hasn't got a leg to stand on, except for one very big leg;- He's got the money and I don't. ergo: gently caress this industry. I accepted a full time job last week at another company, where some other schmuck can deal with smacking sense into dirtback clients, and I'm lighting this loving bridge on fire.
