NSpoint from NSTextView insertion point

Question

I have an NSTextView and require the coordinates of the insertion point to display a view there upon user interaction.

There is a function to get the character index from an NSPoint. I am wondering if there is any easy way to do the opposite?

Thanks for any help!

Answer 1

当然： [textView firstRectForCharacterRange:[textView selectedRange]];

Answer 2

You might be able to do it with an NSTextView subclass, overriding -drawInsertionPointInRect:color:turnedOn: to cache the drawing rect and using the center of the rect (or some other interior point).

NB: I haven't tried this.
