Is it possible to store secure local user data about how many virtual coins a user owns in a unity iphone app, or does the information have to be stored in a database using php/mysql?
I’ve been reading a little about it in ios development forums but don’t know if the advantages or disadvantages are the same with a unity ios app.
You could go another route. Instead of PlayerPrefs, you could save them to a file, that inturn is kept inside a password-protected zip. To further make hacking difficult, you could even encrypt the content of the file. This has downside of being a “disk” operation, but should work nonetheless. Or you could save them to a cloud BaaS service like gamesparks, bolt, braincloud, etc.
Its certainly possible to store data about anything with Playerprefs
You could obtain some security by requirering a userid/pwd so you know you show your virtual currency elements to the authorized user.
But it may not satisfy your security requirements
I know anbsoft has a save game tool, that you may want to look into, its called EZ Game Saver, check it out at The middleware section
