Yeah, same on an iPhone. Just hold down on a given letter for accented variations thereof. To save time, of course, you can also set up a typing shortcut for your name, through Settings>General>Keyboard, then “add new shortcut”, e.g. if your name is Ibáñez, you could set up a shortcut that would turn “Iba” into “Ibáñez”
Yes, but to save having to do that, you can set up a shortcut, so that you can type the unaccented form (or just an abbreviation) and it replaces with the correctly spelled version.
iPhone typing shortcuts are very handy, e.g. in a text message I can type “otr” and it replaces to “On train, should be home about”, then I can just fill in the time and send it to let my wife know when to expect me. Saves a bunch of typing.
Edit: weird, your edit also changed the quoted text!
