Earlier this year I mentioned the excellent FXForms library allowing you to create table view based forms with a wide number of features.
Here’s a submitted library for data validation that can work with Core Data, or a raw NSObject and added support to make it easier to work with FXForms.
FXModelValidation provides a nice syntax for creating validation rules, and provides a number of built-in validators. With the built in validators you can easily verify input is not empty, is a url, is an e-mail, matches a regular expression, is of appropriate length and more.
An example is included utilizing the FXForms library.
You can find FXModelValidation on Github here.
A nice powerful data validation library.
