Happy to help! iOS has a few built-in ways of translating text that generally involve long pressing and hitting translate from the menu or selecting the text, tapping the selected text, and hitting translate in the menu. If you select measurements, unit conversion is also in this menu.
However, every way involves the text being [selectable] text and not something like an image (unless you use your method). And you said button, and I am not positive if a long-press will trigger the press event.
