iOS tutorial: progress indicator on status bar

5 01 2013

Here I will demonstrate how to show progress indicator on iPhone’s status bar. It is standard user interface element, so it is self explanatory to the user and extremely simple to develop.

Use it to indicate that some processing is taking place (for example network communication). This is how it is going to look like:
