This applies from 01-09-2014 to the release date of a vuforia package possibly newer than version 3 to 3.0.10.
If using Qualcomm’s Vuforia plug-in for unity version 3 – 3.0.10 this is what I found was required for building, vuforia to date does not support IOS 8 SDK builds, but will play with retro IOS7.1 SDK build mode with the corrections described below:-
Use xcode 5.1.1 (min required to get a build to apple) don’t use xcode6 will not work unless you can get the ios7.1 sdk in there somehow. (download from dev tools member center, if you upgraded)
Don’t use latest unity 4.5.2 this has some great IOS 8 fixes (like fixes to stop native unity ios movie playback controls from showing, when specified) , but it screws with the vuforia stuff on IOS 8 platforms, it may work backwardly for IOS 6, IOS 7 builds (untested), but it does mess IOS 8 builds totally (qcar errors drop out straight away will not start).
Using Unity 4.3.1 (possibly some versions in between ) building to target IOS 6 (player settings) but building in xcode with latest IOS7 or 7.1 sdk (xcode settings), using Xcode 5.1.1, works on IOS6 (possibly) IOS7 and IOS8 :-
IOS 6 and 7 devices should just work bar a vuforia media plugin playback issue on 64bits Iphone5s and Iphone6, and supposedly 64bit pads running ios7, the requirment if using that movie texture method is to keep them all at exactly 640px x 480px, with default mp4 base layer settings, anything else to knowledge will help crash a 64bit device.
IOS 8, will work when built with IOS7.1SDK (as described above) however, when you first access a scene with qcar, it will trigger a ask for camera use permission pop up, and if your already executing qcar and the camera view should be showing on screen, if you click yes or no, screen will not show the webcam view as an error has already hit qcar, so the app then has to be exited and then restarted to work, causing bad karma and apple do not like this (allegedly).
To let your app (apparently) pass validation, the two fix choices are:-
a) amend a file in your project files per build in xcode and add this statement at the beginning (this then gets accepted by apple and will save you any nightmares, apparently)
In xcode switch project file view find:-> UnityAppcontroller.mm
then do as below:-

//Add the line below at the top of the script somewhere:- #import <AVFoundation/AVFoundation.h> //Find the following method/function:- //- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions { //Add the below:- // Determine camera access on iOS >= 7 if ([AVCaptureDevice respondsToSelector:@selector(requestAccessForMediaType:completionHandler:)]) { // Completion handler will be dispatched on a separate thread [AVCaptureDevice requestAccessForMediaType:AVMediaTypeVideo completionHandler:^(BOOL granted) { if (YES == granted) { // User granted access to the camera, continue with app launch } else { // User denied camera access // warn the user that the app requires camera access // and ideally provide some guidance about the device Settings UIAlertView *message = [[UIAlertView alloc] initWithTitle:@"Camera Permission" message:@"This App doesn't have permission to use Camera, please change privacy settings" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [message show]; } }]; } else { // iOS < 7 (camera access always OK) // Continue with app launch... } Below this should look continue as before and look something like:- //this part is for information only and should already appear in the code (it’s just here to make sure you got the right place) printf_console("-> applicationDidFinishLaunching()\n"); // get local notification if (&UIApplicationLaunchOptionsLocalNotificationKey != nil) { UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey]; if (notification) UnitySendLocalNotification(notification); } //Hit save and build away you good to go. |
b) roll your own, somehow detect ios 8, trigger webcam prompt and handle before it reaches qcar.
the first solution does work, but it must be added per build though I guess.
If using unity.handheld.playmovie there is a fix for IOS 8 in unity 4.5 (which sets the controls displaying properly or not) however I had issues getting a build with IOS7sdk and vuforia to work, I guess end users on IOS 8 will have to put up with this tiny glitch until we hopefully get an vuforia IOS8 sdk compatible library that can be build from unity 4.5 onwards etc, or anyone else has a hack whilst in this waiting period it would be gratefully accepted?
hope this helps someone out there, and saves someone time wasted.
