How can I save an array using Parse?

I am struggling to use Parse to save an array of data - or at least I am finding I can't verify that my data is being saved.

I have a PFObject (journey) and I want to update it with my location (a string in the format: @"{lat, long}").

Eventually though I want to update and save my location every 10-30 seconds meaning I don't want to create a new object each time rather I want to add an array to the object and then update the array each time I have a new location.

Currently my code looks like this:

- (IBAction)startJourneyButtonPressed:(id)sender {

    PFObject * journey = [PFObject objectWithClassName:@"Journey"];
    journey[@"company"] = _companyNameTextField.text;
    journey[@"destination"] = _destinationTextField.text;

    [journey saveInBackground];

    NSData * faceImageData = UIImagePNGRepresentation([_faceButton imageForState:UIControlStateNormal]);
    PFFile * faceImageFile = [PFFile fileWithName:@"faceImage.png" data:faceImageData];

    [faceImageFile saveInBackground];

    NSData * carImageData = UIImagePNGRepresentation([_carButton2 imageForState:UIControlStateNormal]);
    PFFile * carImageFile = [PFFile fileWithName:@"carImage.png" data:carImageData];

    [carImageFile saveInBackground];

    journey[@"faceImage"] = faceImageFile;
    journey[@"carImage"] = carImageFile;

    [journey saveInBackground];

    NSMutableArray * locationArray = [NSMutableArray new];
    [locationArray addObject:[self getCurrentLocationString]];

    journey[@"location"] = locationArray;

    [journey saveInBackground];
}

The strings are saving fine and so are the images but the dataBase doesn't seem to be getting uploaded with the array.

Here is a screenshot of my database:

I am expecting to see a "location" heading but obviously it isn't appearing.

Reading up on other forums it says that I have to have an object in JSON format for this to work but as I am only storing Strings and I am not receiving and JSON errors I don't think this is the issue.

Any help would be very appreciated

Probably it is saving your array, you should just manually in your database add column with name "location" (do not forget to set it as array type) to see the values.
