Now that AssetsLibrary
has been deprecated, we're supposed to use the photos framework, specifically PHPhotoLibrary
to save images and videos to a users camera roll.
Using ReactiveCocoa, such a request would look like:
func saveImageAsAsset(url: NSURL) -> SignalProducer<String, NSError> {
return SignalProducer { observer, disposable in
var imageIdentifier: String?
PHPhotoLibrary.sharedPhotoLibrary().performChanges({
let changeRequest = PHAssetChangeRequest.creationRequestForAssetFromImageAtFileURL(url)
let placeholder = changeRequest?.placeholderForCreatedAsset
imageIdentifier = placeholder?.localIdentifier
}, completionHandler: { success, error in
if let identifier = imageIdentifier where success {
observer.sendNext(identifier)
} else if let error = error {
observer.sendFailed(error)
return
}
observer.sendCompleted()
})
}
}
I created a gif from a video using Regift and I can verify that the gif exists inside my temporary directory. However when I go save that gif to the camera roll, I get a mysterious error: NSCocoaErrorDomain -1 (null)
, which is really super helpful.
Has anyone ever experienced this issue?
