I'm a new cocoa developer and I'm about to finish my 3rd app. I am happy with my app except the interface. All the UI Controls are basically dragged from IB with no customization.
If you look at apps like wunderlist or twitter they both have stunning, customized interface. Too bad they aren't open source
I have found some tools like https://www.cocoacontrols.com/controls/snrhudkit
this is good but like the developer says it's far from done.
It will be great if you guys can tell me if there is any book, online tutorial, open source code, or even tools like snrhudkit help me build a stunning GUI for mac app.
