具有多个故事板的UITabBarController

Question

I am developing an iOS app with Xcode 8 and Swift 3.

I have a Tab Bar Controller with one tab view embedded into a Navigation Controller , as you see below:

As the project continues, the storyboard is getting bigger. I really don't like it. So, I would like to divide it into multiple storyboards.

My question is:

How to divide a Tab Bar Controller & the associated tab's view controllers into multiple storyboards? What is the best practice to do it? And how to do it?

Answer 1

If your target is iOS 9 and above , you should create storyboard references for the view controllers you want to include in another storyboard. Here's how it works:

1. Create a second storyboard, move the desired view controller into it and give it a Storyboard ID under the Identity inspector .

2. Go to your first storyboard and search for Storyboard Reference in the Object library.

3. Drag it into your storyboard and create a "view controllers" relationship with the tab bar controller just like you would with a view controller.

4. Under the Storyboard Reference's Attribute inspector , change your settings accordingly. For Referenced ID , use the view controller's ID on the second view controller.
