Is it possible to add a button in the IPhone Calendar Event creation/edit view?

I want to customize the IPhone Calendar Event view by adding a new button. The purpose is to allow the user to click on this button and then browse to select in a list the name of a friend. The name should then be written in the "note" field of the calendar event.

Is it po开发者_开发知识库ssible to modify such standard view?

Thanks Charles

No, this isn't possible. The iPhone SDK doesn't provide any official way to access calendars or the Calendar app from 3rd party applications.
