MSLogin-Form
Description
MSLogin-Form was developed by a student of Control and Automation Engineer that have been working with iOS applications for 1,5 year. Feeling the necessity to have a form in all applications that he worked, this library was build for those who need a form into their application. It also has a controller class for login that handle inputs from user and enables or not the login button based on an email address and the password length. It's easy to setup and you can find it on the example.
This library is multi-language. It contains English and Portuguese versions. See how to use Portuguese version bellow.
Example
To run the example project, clone the repo, and run pod install from the Example directory first.
