BMQVRDemo

一个简单的VR,暂时只实现了图片旋转,图片点击事件后续再补上

1.导入AVFoundation.framework CoreGraphics.framwork Foundation.framework CoreLocation.framework

2.监听磁场 self.locationManager = [[CLLocationManager alloc]init]; self.locationManager.delegate = self; [self.locationManager requestWhenInUseAuthorization]; [self.locationManager startUpdatingHeading];

3.开启陀螺仪 代码太长，看Demo

4.开启摄像头 _device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo]; // Input _input = [AVCaptureDeviceInput deviceInputWithDevice:self.device error:nil]; // Output _output = [[AVCaptureMetadataOutput alloc]init]; [_output setMetadataObjectsDelegate:self queue:dispatch_get_main_queue()]; // Session _session = [[AVCaptureSession alloc]init];

[_session setSessionPreset:AVCaptureSessionPresetMedium];

if ([_session canAddInput:self.input])
{
    [_session addInput:self.input];
}
if ([_session canAddOutput:self.output])
{
    [_session addOutput:self.output];
}
// 条码类型 AVMetadataObjectTypeQRCode
_output.metadataObjectTypes =@[AVMetadataObjectTypeQRCode];

// Preview
_preview =[AVCaptureVideoPreviewLayer layerWithSession:_session];
_preview.videoGravity = AVLayerVideoGravityResizeAspectFill;
_preview.frame =CGRectMake(0,0,APP_FRAME_WIDTH,APP_FRAME_HEIGHT);
[_session startRunning];
