Recently I was working on Sencha Touch, Phonegap application where we have a requirement to change background color of top status bar of iPhone where we have carrier, wifi and battery symbols. There are two ways to do it. In this blog I will explain both the steps.
In iOS 7 if you have status bar visible your UI will overlap the status bar and we will take advantage of it. First select your project and go to Deployment info. Make sure you have Hide during application launch checkbox and set status bar style as default.
