Setting default tab in UITabBar in swift

Question

I'm almost finished with a project and am working out the last few UI kinks. My app uses a tab bar to navigate and for aesthetic purposes I want the app to open on the last tab (User Profile) instead of the first. I know I can reorder the tabs in Interface Builder but the tab bar would just look odd having the profile tab first and the home tab anywhere else. How can I leave the profile tab as the 5th tab yet by default open the app on that tab?

Answer 1

There is a nice way to do this straight from interface builder on your tab bar controller click the identity inspector, and set a User Defined Runtime Attribute.

In this case each index of the tab bar control is indexed like a 0 based array. So the far left is 0, next to the right is 1, then 2 etc...

So in my case I wanted 'tasks' to be selected first, so you set the selectedIndex to type Number and value '1'. Refer to my attached image.

Just set the selectedIndex of the tabBarController. Something along these lines.

var freshLaunch = true
override func viewWillAppear(animated: Bool) {
     if freshLaunch == true {
         freshLaunch = false
         self.tabBarController.selectedIndex = 4 // 5th tab
     }
}
