Question

iOS 13 beta4 no longer gives

1) PHImageFileURLKey 2) PHImageResultIsDegradedKey in image result info keys.

Anyone knows a way to find the fileurl of the P

Answer 1

You have to use this function from PHAsset object:

- (PHContentEditingInputRequestID)requestContentEditingInputWithOptions:(nullable PHContentEditingInputRequestOptions *)options completionHandler:(void (^)(PHContentEditingInput *__nullable contentEditingInput, NSDictionary *info))completionHandler;

Then you can retrieve URL this way:

NSURL *url = contentEditingInput.fullSizeImageURL;

Answer 2

Some example Objective-C code for anyone else looking for it:

PHContentEditingInputRequestOptions *editOptions = [[PHContentEditingInputRequestOptions alloc] init];

[myPHAsset requestContentEditingInputWithOptions:editOptions completionHandler:^(PHContentEditingInput *contentEditingInput, NSDictionary *info) {

    if (contentEditingInput.fullSizeImageURL) {
        //do something with contentEditingInput.fullSizeImageURL
    }

}];

Answer 3

With the suggestion of guhan0, I made a small change. Indeed, sometimes, there are more than 1 "fileURL:...", so, I take the first when the value start with "file://" which means there is a file url. I think there is a better solution, but for now, it works well:

private func getFileURLFromPHAssetResource(resourceDescription description: String) -> String? {

        let regex = try! NSRegularExpression(pattern: "(?<=fileURL: ).*(?=\\s)")

        for match in regex.matches(in: description, options: [], range: NSRange(location: 0, length: description.count)).lazy {

            let url = String(description[Range(match.range, in: description)!])

            if url.starts(with: "file://") { return url }
        }

        return nil
    }
