Interface orientation

[fabiomassimo]

Don't know if it is also linked to ARC / non ARC issue but I was trying to add rotate orientation feature by adding this snippet of code:

-(void)startCamera { [...]
    switch ([[UIApplication sharedApplication] statusBarOrientation]) {
        case (UIInterfaceOrientationLandscapeLeft):{
            [cameraLayer.connection setVideoOrientation:AVCaptureVideoOrientationLandscapeLeft];
        }
            break;
        case (UIInterfaceOrientationLandscapeRight):{
            [cameraLayer.connection setVideoOrientation:AVCaptureVideoOrientationLandscapeRight];
        }
            break;
        default:
            [cameraLayer.connection setVideoOrientation:AVCaptureVideoOrientationPortrait];
            break;
    }
     CGRect layerRect = CGRectMake(0, 0,
                              deviceScreenResolution.width,
                              deviceScreenResolution.height);
    [cameraLayer setBounds:layerRect];
    [cameraLayer setPosition:CGPointMake(CGRectGetMidX(layerRect),CGRectGetMidY(layerRect))];
}

and this new function:

-(void)updateARwithScreenSize:(CGSize) screenSize {
    [cameraSession stopRunning];
    [refreshTimer invalidate];

    deviceScreenResolution = screenSize;

    locTries = 0;
    dataTries = 0;

    [self initAndAllocContainers];
    [self startPosMonitoring];
    [self startCamera];
}

but it crashes and console output is:

malloc: * mmap(size=231432192) failed (error code=12) * error: can't allocate region *\ set a breakpoint in malloc_error_break to debug

Thanks again for all.

Hey,

Uhm yea thats going to be a little more complex... I've never tried adding landscape orientation to it.

• One thing is that the constant OVERLAY_VIEW_WIDTH is based on the width of the portrait view...
• When you initAndAllocContainers, startPosMonitoring & startCamera it just re-allocates everything.. so I'm not sure how well ARC handles the deallocations

Unfortunately I'm leaving for vacation in a few days so I don't think I'll have too much time to look at this :/ I'll try a few things though

Maybe experiment with a few things.. the memory management lacks some stuff for re-usability (right now you can't really turn AR on and Off unless you release or dismisss the view which is calling everything... --> that triggers all the deallocs and releases)

Hope that helps

Any updates on this?
