Any better way to save a file/string on iOS for project to recall?

[playpm]

Thanks for reply, I already used the setProperty in state for saving the file name, what it lacks is a way to save a URL bookmark which is converted into string in object C in order to recall the local file.

I used this way to embed the object C functions according to this post:

iOS and get/setURLBookmark

I’m working on an iOS app that needs to store and load file locations. It seems that the proper way to do this on iOS is to store the bookmarkData in a file or database for later retrieval. I started down this path, seeing get/setURLBookmark methods in the URL class, but alas they are private… any chance we could have some kind of interface to these without hacking the URL class? Or maybe make them protected? What I’m working towards is converting the underlying NSData to/from String for stora…

But got no luck to retrieve the saved string, the AUv3 will crush on next time project opening.

Here’s my code for get and set state information:

void HelloSamplerAudioProcessor::getStateInformation (juce::MemoryBlock& destData)
{
    std::unique_ptr <juce::XmlElement> xml (mAPVTS.state.createXml());
    xml->setAttribute("pathURLBookmarkString", bookmarkEncoded);
    copyXmlToBinary(*xml, destData);   
}

void HelloSamplerAudioProcessor::setStateInformation (const void* data, int sizeInBytes)
{
    std::unique_ptr <juce::XmlElement> xmlState (getXmlFromBinary(data, sizeInBytes));
    
    if (xmlState != nullptr)
        {
            if (xmlState -> hasTagName(mAPVTS.state.getType()))
            {
                juce::String bookmarkString = xmlState->getStringAttribute("pathURLBookmarkString", "");
                mAPVTS.state = juce::ValueTree::fromXml(*xmlState);
            
#if !JUCE_IOS
            auto filePath = mAPVTS.state.getProperty("currentFilePath", "").toString();
            auto filePathURL = juce::URL(filePath);
            HelloSamplerAudioProcessor::loadFile (filePathURL);
#else
            juce::MemoryBlock bookmarkMemoryBlock;
            bookmarkMemoryBlock.fromBase64Encoding(bookmarkString);
            auto path = NSURLUtils::lastKnownPathFromBookmark(bookmarkMemoryBlock.getData());                
            auto url = NSURLUtils::URLfromBookmark(bookmarkMemoryBlock.getData());
            HelloSamplerAudioProcessor::loadFile (url);
#endif
            }
        }
}

Everything works fine on Mac and PC, but not the iOS .
