How-To: Jump between tabs using UITabBarController
Dec.31, 2008 in
Tech, iPhone Development
Sometimes you want to jump between tabs in your iPhone app programatically (ie you don’t want the user to have to touch the tab prior to displaying it). This is very easy to achieve:
self.tabBarController.selectedIndex = 3;
Where selectedIndex reflects the tab you wish to select (from left to right, starting at 0 for the first tab). The only thing to note, is that the UIViewController viewWillAppear method will not get called. So you may need to call this yourself, if you need to do something on the tab prior to it being displayed:
self.tabBarController.selectedIndex = 3; [self.tabBarController.selectedViewController viewDidAppear:YES];

I have been trying to perform the above coding statment from a NSThread, but cannot seem to get it to work. My setup: from within the App delegate I create an NSThread. When external events occur, I programatically try to go to a desired tab. However, nothing seems to work. Some sites indicate there may be issues when doing this from a thread. My NSThread passes the ‘this’ reference (the app delegate), hence I can get access to the UINavigationController and UITableViews, etc,.
Any ideas.
