Load a tabBarController from a UIButton in a subview

I am working on an app where i have a vie开发者_运维问答w controller that contains a view in that view i have a button that when pressed i would like it to load my tabViewController.

I trying to get a splash screen to load before my app so i can do some downloading and parsing of data before i load my tabViewController because the data im putting the data into a tableView that is in the tabViewController.

1. Here's a good example on creating a splash screen http://adeem.me/blog/2009/06/22/creating-splash-screen-tutorial-for-iphone/
2. I would suggest that you look into using performSelector and launching a background thread before putting your splash screen up to populate/parse the data.
