Awesome, thanks! On that note, any reason why UITapGestureRecognizer would "work" in the simulator, but once on a real device, it doesn't receive any taps? Found this one bug only after deploying on my device, it was working perfectly on the simulator. Is there a situation where the device is able to distinguish between different kinds of touch events and the simulator cannot?

Is it a small area that receives the tap? I always find that I'm much more precise with a click of the mouse (duh) and sometimes things aren't as easy as they were.

Is it possible to set separate storyboards for separate devices? I'm aware of autolayout, but there are some things I could do with the extra real estate on the iPhone 5...

I don't think there's anything automagic. You'd have to detect the bigger screen in code and then use the appropriate storyboard.

Using the notification MPAVControllerPlaybackStateChangedNotification solves a problem for me in my app, but I am concerned that using it will block my app from the app store since it is not documented. Does anyone have any insight on my chances, or suggestions on whether or not to use it? It really is the only way to provide a convenient feature to my app.

I would make sure your app still works without that notification, since you're relying on undocumented behaviour, but I doubt using that notification would net you a rejection. Anyone can listen to everything passing through a NSNotificationCenter, that's the entire point.

I'm a little confused about Testflight. Am I correct in assuming from what I've read that: 1. Developers have access to a master dashboard showing all devices and the versions of the app installed. 2. Developers can wirelessly push new versions of the app to selected devices without user interaction. 3. Developers can use Tflog like NSLog to log things, then remotely access those logs from the dashboard. Edit: I'm really vague on what I'm even supposed to be doing. There are no screenshots of the dashboards that I can find, no examples on how to get started... do I just grab the SDK and put it in the app? Not a big fan of the site... tarepanda fucked around with this message at 00:35 on Nov 8, 2012 |

1)yes 2)no, user interaction is required 3)yes, it sends them off to TestFlight (you aren't remotely accessing them on the user's device or anything like that) In order for TestFlight to be the most useful you have to send it the user's UDID, but Apple doesn't allow this and will reject your app. So I have some macros that call TestFlight when compiled with BETA_TEST defined, log to the console for regular debug builds, and do nothing for distribution builds. edit: they have directions right there on the site.

Download the SDK, and on the download page there'll be a link to the SDK documentation, including how to set it up. You might have to create an account first, I don't remember.

Doc block, you might be able to help with this. I'm using a subclass based on Doc block's AVfoundation stuff that he graciously posted earlier; I have a UIView that I made in the storyboard editor and set to that subclass. Every time I switch to that particular scene, my memory usage jumps up... and doesn't go down accordingly if I leave the scene. However, if I never start the capture session, the memory usage doesn't jump up. Am I doing something fundamentally wrong here? tarepanda fucked around with this message at 08:16 on Nov 8, 2012 |

Well if it helps, Testflight will notify users when a new build is available and tracks who actually installed it, all without the SDK. Have you done a simulate memory warning in the simulator? The AVFoundation classes seem to cache a lot of stuff so long as memory is available. For playback it adjusts how much it caches from flash based on memory. Speaking of, is this on device or in the simulator? Could be a good old fashioned memory leak too. Simulated fucked around with this message at 14:19 on Nov 8, 2012 |

Hopefully it isn't a memory leak. I use that class in a shipping app, and didn't see any memory leaks in instruments. Does the memory usage keep jumping every time you go to the camera view, or does it just go up and stay up the first time? It could be AVFoundation itself getting loaded. Does the leaks instrument show anything? edit: you're compiling it with ARC, right?

Using ARC. It jumps by about 10 MB every time the view appears and never goes back down. The other view I'm using it in works fine and transitions without leaks at all. The only difference between the two is that one is the actual view and the other (the leaky one) is a view inside the view in a scene. Leaks tool and Analyze tool didn't find anything.

Can one test one's app with the AppStore provisioning profile? I'd like to get as close as possible to the final thing in testing before submitting it. Also, do I need to create a new profile for each certificate that was enabled for a new iOS capability such as Remote Notifications? As in, I already have a non-Push-enabled AppStore profile from the previous version. I added the capability in the new version. Do I need a new profile?

This is after the view loaded.code: *edit* And yes, I added UIActionSheetDelegate to the ViewController. It's a UITableViewController.

You do an archive using a distribution profile, then do Distribute...->Save for Enterprise... and make an IPA using an Ad Hoc distribution profile. You can then install that IPA on your device from the Device panel of the Organizer. After you test that IPA you can submit the same build without changing anything.

The leaks tool by itself doesn't do much good under ARC. You need to be using the Allocations instrument and doing heapshots, looking for the top-most object that is leaking and finding a circular reference that's keeping it alive. I believe you can go into the Leaks tool and see all of the retain and release statements that reference said object, even under ARC, though I've had mixed luck doing so.

tarepanda, make sure your completion block isn't retaining self. Only thing I could think of off the top of my head. I'll look into SRCameraView tonight and see if I missed anything. In my app I push and pop it and its view controller onto a navigation controller without any obvious memory leaks. Memory usage goes up when it's created (though not by 10MB IIRC), then back down when it's destroyed.

That's strange. Maybe the problem isn't SRCameraView but the other view? Also, I looked at SRCameraView again and couldn't find any problems. The idle memory consumption of the CameraTest app hovers around a megabyte. When a picture is taken memory usage jumps up to 32MB (!!!) on my iPhone 5, but goes back down after you hit Retake or Use. edit: pushed a small update to Github. No drastic changes, certainly not anything that would make a 10MB memory leak go away. Doc Block fucked around with this message at 07:17 on Nov 9, 2012 |

Basically any archive build that has an "iPhone Distribution" code signing identity, as opposed to "iPhone Developer" identity, can be submitted to the App Store or distributed with a distribution Ad Hoc cert. So, yes, I think?

Plorkyeran posted:No, not necessarily. Static analysis cannot be both complete and sound without running into the halting problem, and while clang's analyzer is quite impressive, it's not that hard to trick. It also has some outright bugs; at least in 4.3 it did not detect self-retains which used the dot syntax. Crap -- I use the dot syntax everywhere, too. Edit: Doc Block, I don't think it's you. I went back into Allocations and tried some other things -- apparently every time I go to the other scene, it makes a new instance of the cameraview AND the view controller. Every single time. Edit 2: Apparently, for some reason, the scene is calling viewDidLoad every single time it appears... Edit 3: And apparently my big leak is due to a CIFilter applied in one scene that's retained when we go to the next, though all of them are released properly if you go back to the original scene... huh. tarepanda fucked around with this message at 01:16 on Nov 10, 2012 |

This is a bit of a longshot, but does anyone have experience with using Core Audio with app sandboxing? I've just enabled sandboxing, and now my Core Audio code doesn't work. In particular, when I call AUGraphAddNode, it returns the error invalidComponentID, saying just "The operation couldn't be completed". A number of other Core Audio calls seem to work correctly before that, though. It doesn't seem to be a direct sandbox violation, as there aren't any messages from sandboxd in Console, but it definitely works when I turn off sandboxing. Anyone know why this would possibly happen? The only thing I can imagine is that maybe it's trying to read files that I don't have access to, although I would think that would give me a sandboxing error. Update: I've narrowed down the issue a little bit. AUGraphAddNode only fails if I try to add a node with the component type kAudioUnitType_MusicDevice and subtype kAudioUnitSubType_DLSSynth, so it seems to be an issue with that particular component in sandboxing mode. Update 2: I've figured out a hacky workaround. If I add a temporary exception entitlement to enable read-write access to the user's entire home directory, the error no longer happens. This is obviously not ideal, so I'm continuing to search for better options. I tried to narrow down the access required by adding entitlements for more specific subdirectories, but that didn't work. dizzywhip fucked around with this message at 01:54 on Nov 11, 2012 |

You spend enough hours on something stupid, it's time to ask for help. I have a Cocos2d project and a CCScene "MainDisplay" that has been getting touch events just dandy until now. I downloaded a UIView/Controller from an opensource project I wanted to use and added it to MainDisplay using: code:The MLGViewController receives it's own touch events, and I'm not really able to remove it as a subview and manually funnel in the touch events from the MainDisplay class because within the MLGViewController there is this method: code: I'm ok with with not knowing too much about UIKit, I don't really need it for what I'm playing with, but this UIView is perfect and I really would like to use it - is there a solution I'm missing here? I'm hoping there's something obvious to one of you folks that I'm missing.

It would be helpful to know what you're trying to do with MLGViewController. From what I can see, it's just an example view controller to show how to make an MGTileMenu. You should still be able to funnel touch input into the other view. The line CGPoint point = [touch locationInView:self.view]; is just converting the touch input coordinates (which are in screen space IIRC) into the view's coordinates. You should be able to call the method yourself from your own touch handler methods. If you're just trying to detect a double tap so you can pop open an MGTileMenu, it'd probably be better to just detect the double tap yourself. The version of MLGViewController on GitHub doesn't use -touchesBegan:withEvent:, but instead uses a double tap gesture recognizer.

Should the CoreAudio part of your app be in a service process that has more permissive entitlements?

Yes, yes and yes. It did all these things and everything is wonderful in the world  I didn't realize you could just pass it into locationInView, I had tried that since it seemed obvious and it didn't work, but it was something else at the time buggering it up so I did it again and it worked. I'm detecting the double tap myself so we're good. Cheers.

The only locations I know of where audio components are stored only have components that I've added myself, so I'm not sure where the native ones are. It does seem likely that that component is loading files that could be outside of the sandbox since it's a sampler, which could explain why this is the only component that causes this problem. What's strange is that it seems to be doing something with the home folder itself. I get the error if I ask for permission for any of its subdirectories, including hidden ones. It seems like a bug to me -- there's nothing about playing MIDI sequences that should require access to any files except the audio samples, and that should be a readable resource without any extra entitlements. I'm filing a bug report, hopefully it'll get fixed.

Hey, I need to check if there's a cookie saved for my app when it starts up. I know how to do all of this; however, how do I do this correctly while developing? Whenever I do a new build, it clears out the cookies for the app thus negating my development testing. I'm trying to check for a cookie that has our login token, and if it's there, move past the login screen.

Cookies shouldn't be cleared between builds, so I'm not sure what that's about. That said, you can grab the cookies from NSHTTPCookieStorage, grab their properties dictionary, and save that. Then you can deserialize them as needed.
