In this video I show you how to eliminate unnecessary Event Listeners in your Appcelerator Mobile App by making use of the Bubble Parent property. This is a great way to increase performance and responsiveness in your mobile app, especially when it requires some advanced processes.
The video below demonstrates the the Bubble Parent technique when using Text Fields inside Table View Rows for an iOS app. I’m sure you’ll immediately understand how you can apply it elsewhere in your mobile application, whether developing for iOS or Android.
As always just a thanks to David Leedy for hosting this video on NotesIn9. Always appreciated
