Question

是否可以更新此代码以在模拟器中运行？现在，当我在代码中达到这一点时，应用程序正在处理崩溃。是否有我们可以添加的nslog语句允许我测试此功能？我需要在iPad和模拟器上同时测试，但是当我到达此代码时模拟器崩溃。

- (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];
}

不能在模拟器中使用相机。尝试加载相机并且硬件不存在时会崩溃。您需要将设备用于所有这些功能。如果您只需要相机，iPod touch是一个很好的解决方案。

在iOS模拟器中测试iPhone相机？
