Correct output format of page number using \cite command

Question

I am using biblatex, style=ieee, to create my bibliography.

In text I want the following cite with page number to look like this [1:123], but all online resources seem to insist that I should use \cite[p.~123]{keyword} giving the output [1, p. 123]. How do I get the format I want?

Edit

To make clear what my code looks like

\documentclass[12pt,titlepage,a4paper,draft]{article}
\usepackage[utf8]{inputenc}

\usepackage[style=ieee]{biblatex}
\addbibresource{References.bib}

\begin{document}

\section{Introduction}
This is a very nice introduction \cite[123]{Ref1}

\printbibliography

\end{document}

And my .bib file looks like this

@book{Ref1,
address = {North pole},
author = {Ann Author},
edition = {1},
publisher = {Name},
title = {{This is a very nice title}},
year = {2017}
}

Answer 1

With

\renewcommand*{\postnotedelim}{\addcolon}
\DeclareFieldFormat{postnote}{#1}
\DeclareFieldFormat{multipostnote}{#1}

we tell biblatex to use a colon between citation label and postnote, and to drop the 'p.' in postnotes.

So \cite[123]{sigfridsson} results in

[1:123]

Answer 2

Use the \nopp option. E.g. \cite[\nopp 123]{key}

Check Section 3.13.3 of manual for more details.

Answer 3

Try this code:

\documentclass{article}
\makeatletter
\def\@cite#1#2{[{#1\if@tempswa:#2\fi}]}
\makeatother
\begin{document}
\cite[123]{xxx}
\begin{thebibliography}{1}
\bibitem{xxx} xxx
\end{thebibliography}
\end{document}
