iOSMath is an open source component from Kostub Deshmukh for displaying math equations in iOS applications within a UILabel type class.

Equations in iOSMath are created using the popular LaTeX mathematics markup format and the following formula types are supported by the library according to the readme:

Simple algebraic equations

Fractions and continued fractions

Exponents and subscripts

Trigonometric formulae

Square roots and n-th roots

Calculus symbos – limits, derivatives, integrals

Big operators (e.g. product, sum)

Big delimiters (using \left and \right)

Greek alphabet

Combinatorics (\binom, \choose etc.)

Geometry symbols (e.g. angle, congruence etc.)

Ratios, proportions, percents

Math spacing

Overline and underline

Math accents

Matrices

Equation alignment

Most commonly used math symbols
