在开发iOS应用时，使用多个Storyboards可以更好地组织代码和界面逻辑。但如何实现不同Storyboard间的平滑跳转呢？首先，你需要在`AppDelegate.swift`中设置主Storyboard：

```swift

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

let mainStoryboard = UIStoryboard(name: "Main", bundle: nil)

window?.rootViewController = mainStoryboard.instantiateInitialViewController()

return true

}

```

当需要从一个Storyboard跳转到另一个时，可以使用`instantiateViewController(withIdentifier:)`方法。例如，假设你想从`FirstStoryboard`跳转到`SecondStoryboard`，可以这样写：

```swift

let storyboard = UIStoryboard(name: "SecondStoryboard", bundle: nil)

if let secondVC = storyboard.instantiateViewController(withIdentifier: "SecondViewController") as? SecondViewController {

self.navigationController?.pushViewController(secondVC, animated: true)

}

```

记得给目标ViewController设置正确的Identifier！通过这种方式，你可以轻松管理复杂的多Storyboard项目，让应用结构更加清晰整洁。💡
