How do I fix text alignment on ios devices ?

This is an old and known problem with texts in C3 - some fonts are rendered differently on different platforms.

Try other alignment options - top, bottom.

Try a different font.

If nothing helps, use a spritefont.

I haven't tried it yet, but you could check if it's running on iOS (with the PlatformInfo plugin). If it is, then run a function when you create the text to set the y position to Self.Y - (the value you need) and set the height to Self.Height + (the value you need), so the text isn't cut off.

I had this problem so used a sprite font instead.
