| Availability | Available in Mac OS X v10.6 and later. |
| Declared in | IKCameraDeviceView.h |
The IKCameraDeviceViewDelegate protocol is adopted by the delegate of the IKCameraDeviceView class. It allows downloading of camera content, handling selection changes, and handling errors.
Invoked for each file that is downloaded from the camera device.
- (void)cameraDeviceView:(IKCameraDeviceView *)cameraDeviceView didDownloadFile:(ICCameraFile *)file location:(NSURL *)url fileData:(NSData *)data error:(NSError *)error
The camera device view that sent the message.
The camera file.
The URL to save the data.
The data.
Any errors encountered during downloading.
If the IKCameraDeviceView transferMode property is IKCameraDeviceViewTransferModeFileBased then camera file will have been saved to url. The URL will be a complete path to save the file, including a ‘sequence number’ if the file already exists.
If the transferMode is IKCameraDeviceViewTransferModeMemoryBased then the data parameter contains the image data and can be handled as appropriate for your application.
In case of an error, the passed data (both url and data) will be NULL and error (which may come directly from the camera module / or the ImageCaptureCore framework) will describe why the download or save failed.
