Useful UITextField Extensions
One of the side projects I’m working on is very frontend focused and after spending a lot of time on my designs, I really wanted to give my app a custom look and feel. As a result, I had of modify a lot of UI elements to fit my specific purposes.
Here is an extension for a UITextField that gives two functionalities. The first is a text field with just a bottom border (think material design). The second adds a done button to the keyboard like so:
It’s very useful for the number pad input which doesn’t the native “Done,” “Return,” etc. buttons on the keyboard itself.
One of the things on my bucket list is to build and publish my own libraries. This would not only improve my own development and production speed, but also give you tools/UI tweaks that you might find useful. I don’t typically use libraries in my projects, but I do see their benefit. Because I’m focusing on the learning right now, I’ve been building my own “libraries” from scratch as a teaching tool for myself. Hopefully I can push one of those out to you all soon!
Force Touch Shortcuts
First you must setup your Info.plist file to give your app permission to use Force Touch app shortcuts. Here is a useful tutorial for doing just that: developer.apple.com
Hope this was useful! Sorry my blog posts have been fairly minimal in writing. I haven’t had a lot of time this semester because of my heightened work load. Hope I’ll catch a break soon so I can put some more time and thought into my pieces. Thanks!
