In any app that requires the user to enter data you are going to be doing some sort of validation on the data.
Recently I came across an excellent library that allows you to easily validate data using either regular expressions or by a collection of custom validators.
What I really like about this library though is that you can use it as a drop-in replacement for UITextFields, but the example demonstrates how to use the validation library with very slick looking tooltips and checkmarks that will fit into pretty much any design.
Here’s a video showing the sample app included with the library in action:
You can find the library and example along with detailed usage instructions on Github here.
Definitely one for the bookmarks for whenever you need to have a form in your apps.
