There is nothing that can convert apk to ios app. As far as I know, there is nothing that can translate the Android code into IOS.
However, there are tools you could use to make your apps work on both devices. I'm sure there are more of them, but here are 2 of them I found in a matter of minutes (check them out if you're interested): Apportable , Phonegap
Regarding your existing application, depending on the complexity of your software, you need to rewrite the code a bit for a lot of code to adapt to the IOS API.
In short: No. If your application is not based on a multi-platform framework, converting means manual adaptation.
