跳转
Push时的Controller为 UIViewController
Present时的Controller为 UINavigationController
- 使用 Storyboard Segue 方式:
在Storyboard中设置Segue的Identifier，以及Kind
然后使用代码：
performSegue(withIdentifier: "LoginToMain", sender: nil)
- 使用代码方式：
let storyboard = UIStoryboard(name: "Segue", bundle: nil)
// Push
let viewController = storyboard.instantiateViewController(withIdentifier: "NavigationController")
navigationController?.pushViewController(viewController, animated: true)
// Present
let navController = storyboard.instantiateViewController(withIdentifier: "ViewController")
navigationController?.present(navController, animated: true, completion: nil)
传值
目标是 UINavigationViewControlle r的话，得先取出TopViewController
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "Segue" {
if let nav = segue.destination as? UINavigationController, let controller = nav.topViewController as? ViewController {
controller.intentData = "aaa"
}
}
}
否则：
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "Segue", let c = segue.destination as? ViewController {
controller.intentData = sender as? String // sender 为 performSegue 方法设置的值
}
}
