I’ve an application with a UITabBarController with five tabs.
Tests on real device show that switching from a tab to another, may take one or more seconds to load the views, because I also have to download some data from the Internet.
What I would like to do is to show a UIActivityIndicatorView while the view is loading, but I couldn’t find a solution. Maybe I haven’t searched the right way.
Could someone help me?
You should download any data with an asynchronous request, ASIHTTPRequest is a nice wrapper for this.
Then for the UIActivityIndicatorView these are popular options:
loading anything else in the view.
And when the data is ready just hide
it and show the complete info.
an overlay with the
UIActivityIndicatorView.
