DCTTextFieldValidator takes an array of UITextFields and validates them before allowing an action to take place.
It switches the return key depending on whether or not the text fields are valid, if one or more text fields are invalid, it will make the next one in the array the first responder upon tapping the return key. Once all fields are valid, the keyboard return key will become (for all text fields in the array) that which is assigned to the last text field in the array.
The main thinking is to make sure all of the fields are filled out, and not blank. Though I am considering a post-validation, which would validate each one after the return key is hit, such as checking emails are correct and such. I’ve filed this as a bug on GitHub and would be grateful for any input on this.
Automatic Reference Counting (ARC)
This project uses ARC.
There are two branches to this repository, master and demo.
The master branch contains the code and should be used if you want to add these extensions as a git submodule in other projects. It will only contain the class files themselves without the Xcode project or example classes. This is preferable as it will keep your directories clean of any code which is unnecessary to your working project.
To add this project as a submodule you should run the following from inside your project’s git repository:
git submodule add git://github.com/danielctull/DCTTextFieldValidator.git
To keep up to date with the latest changes `cd` into the directory that contains this submodule and pull the newest changes as usual:
git pull origin
This contains an Xcode project that demonstrates the code and is the branch to use to see how to use the code. The demo branch contains a submodule reference to the master branch to bring in the library classes.
To clone the demo branch, while also pulling in any necessary submodules run the following command:
git clone -b demo --recursive git://github.com/danielctull/DCTTextFieldValidator.git
When changing to the demo branch you will need to run through the following set of commands:
git checkout demo bc. git submodule init bc. git submodule update
After these you will see the example project and the library code will be in a sub-directory.
Sometimes, there may be artefacts left over when switching from demo to master. These are files that are ignored by git and are easily cleaned up by running
git clean -dxf
