ios - 在 iOS 模拟器中测试 iPhone 相机？

Question

是否可以更新此代码以在模拟器中运行？现在，当应用程序到达代码中的这一点时，我正在处理的应用程序就会崩溃。我们是否可以添加 nslog 语句来允许我测试此功能？我需要在 iPad 和模拟器上同时进行测试，但是当我到达此代码时模拟器崩溃了。

- (void)snapStillImage //this is being called on did load
{
dispatch_async([self sessionQueue], ^{
    // Update the orientation on the still image output video connection before capturing.
    [[[self stillImageOutput] connectionWithMediaType:AVMediaTypeVideo] setVideoOrientation:[[(AVCaptureVideoPreviewLayer *)[[self previewView] layer] connection] videoOrientation]];
    // Flash set to Auto for Still Capture
    [ViewController5 setFlashMode:AVCaptureFlashModeAuto forDevice:[[self videoDeviceInput] device]];
    // Capture a still image.
    [[self stillImageOutput] captureStillImageAsynchronouslyFromConnection:[[self stillImageOutput] connectionWithMediaType:AVMediaTypeVideo] completionHandler:^(CMSampleBufferRef imageDataSampleBuffer, NSError *error) {
        if (imageDataSampleBuffer)
        {
            NSData *imageData = [AVCaptureStillImageOutput jpegStillImageNSDataRepresentation:imageDataSampleBuffer];

            photo.image = [[UIImage alloc] initWithData:imageData];
            [[[ALAssetsLibrary alloc] init] writeImageToSavedPhotosAlbum:[photo.image CGImage] orientation:(ALAssetOrientation)[photo.image imageOrientation] completionBlock:nil];
            [self uploadPhoto];
}
    }];
});
}

例如，这里是允许测试 UIImage 选择器的方法，但我正在使用 AVCam...

-(void)takePhoto {
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
#if TARGET_IPHONE_SIMULATOR
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
#else
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
#endif
imagePickerController.editing = YES;
imagePickerController.delegate = (id)self;

[self presentModalViewController:imagePickerController animated:YES];
}

不，你不能在模拟器中使用相机。当尝试加载相机且硬件不存在时，它会崩溃。您需要使用设备来实现所有这些功能。如果您只需要相机，iPod touch 是一个很好的解决方案。
