The ammonia simply acts to complex the Ag+ ion and make it more soluble in water. The net reaction is :
NaF(aq) + AgNO3 (aq) -> NaNO3(aq) + AgF(s)
The ammonia may or may not remain complexed to the Ag after the reaction; if it did, you'd have something like
Ag(NH3)2 F (aq), which would be soluble.
However, this is unlikely as the very electronegative F- ion would probably kick the ammonia out and you'd just be left with your ammonia back in aqeous solution. Plus, these reactions are typically driven by the fact that one or more of the reactants precipitates out, thus making it all the more unlikely complexing lasts for long.
