When using ALAssetsLibrary, I used to save image to photo library with proper exif using the code below:
NSInteger orientation = 2;// Or whatever
NSData *jpegData = [AVCaptureStillImageOutput jpegStillImageNSDataRepresentation:imageDataSampleBuffer];
CMSetAttachment(imageDataSampleBuffer, kCGImagePropertyOrientation,
[NSNumber numberWithInt: orientation],
kCMAttachmentMode_ShouldPropagate);
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
CFDictionaryRef attachments = CMCopyDictionaryOfAttachments(kCFAllocatorDefault, imageDataSampleBuffer, kCMAttachmentMode_ShouldPropagate);
[library writeImageDataToSavedPhotosAlbum:jpegData metadata:(id)attachments completionBlock:^(NSURL *assetURL, NSError *error) {
...
...
}
It's not clear how to translate that code when using PHPhotoLibrary. Can anyone provide the right way to save attachments along with the jpeg image?
