Question

尝试根据所选的segue路径隐藏另一个视图上的按钮。例如，如果＆＃34; AddNewPokemon＆＃34;选择segue，然后在下一个视图页面上显示UIButton.hidden = true。

if segue.identifier == "AddNewPokemon" {

    let navigationController = segue.destinationViewController as! UINavigationController
    let controller = navigationController.topViewController as! PokedexDetailsViewController

    controller.cancelButtonDelegate = self
    controller.delegate = self

我曾尝试过去一小时浏览stackoverflow，但无济于事，相当新的swift。

Answer 1

if segue.identifier == "AddNewPokemon" {
let navigationController = segue.destinationViewController as! UINavigationController
let controller = navigationController.topViewController as! PokedexDetailsViewController

//add line set the value created in PokedexDetailsViewController ie hideButton = true

controller.hideButton = true

controller.cancelButtonDelegate = self
controller.delegate = self

}

在PokedexDetailsViewController控制器中创建一个var hideButton并将其设置为true以准备segue并检查PokedexDetailsViewController viewdidload（）方法如果为true则隐藏它。

希望这可以帮助你。
