Hello iCoders, today I am going to be open sourcing a UITableViewCell we have created over at ELC that we have found to be very useful. When developing apps we have found that many times a form of some type is required. This is common in Registration forms, contact forms, feedback forms, etc. The problem was writing the same basic code over and over to have an elegant fast form experience for the user. To quicken the development time of these elements we created the ELCTextFieldCell class which facilitates the creation and flow of a larger form. In this post I will be walking you through the usage of the class.

We are going to implement the UIAlertView and UIActionSheet protocol methods in order to get the functionality we are looking for. This will be a short project but will show the important methods associated with these views.
