Sorry I didn't explain clearly before. When I tap on a photo in Photos iOS it comes up with the location and date shown at the top of the screen. I want the title to appear - the same title that has been applied to Photos OS X on my MacBook. For example, I have a folder of family history photos, each of which has the person's name as its title. When I tap on the photo on my iPod I want to see who the person is - not where and when the photos was taken.
Incidentally, I tried to search for the title as you and the support article suggested, but nothing resulted, so I suppose the title has not synced from Photos on my MacBook and can therefore not be found, whereas the location and date have synced.
