Hi, I have a UITabbBarController with a UITableView. Under certain circumstances the TabBarControllers dataset requires updating when a user arrives from another view,

e.g. the initial load when the TabBarController is called the first time, or when the settings are changed.

This dataset update takes about 2 seconds and I want to show an UIActivityIndicatorView.

Trouble is that when I enter from another view I don't know which view to attach it to, since the loading of the tabbarController is carried out in the viewWillAppear method.

Any clues how I can go about this?
