'故事板 (<UIStoryboard: 0x7b1800030960>) 不包含标识符为 'GroupProfileViewController' 的视图控制器'

Question

fileprivate func showGroupProfile(_ item:HomescreenLongTapItem) {
    let vc = storyboard?.instantiateViewController(withIdentifier: "GroupProfileViewController") as! GroupProfileViewController
    present(vc, animated: true, completion: nil)
}

我需要在按下 HomescreenLongTap 中的图标后更改 VC，但我收到错误“Storyboard () doesn't contain a view controller with identifier 'GroupProfileViewController' 我在代码中使用了 StoryboardID。我怎样才能正确导航到下一个 ViewController?

Answer 1

这样试试：

    if let vc = UIStoryboard.init(name: "Main", bundle: nil).instantiateViewController(identifier: "GroupProfileViewController") as? GroupProfileViewController {
         present(vc, animated: true, completion: nil)
    }

在故事板中：--> 在自定义 class 中给出此 viewcontroller class GroupProfileViewController

--> identity --> Storyboard ID (GroupProfileViewController) 也给出与 class 相同的名称或您的意愿。

Answer 2

确保设置 viewcontroller 的标识符，假设 "GroupProfileViewController"
确保此代码在 viewDidLoad() 中不是。如果有，请考虑在 viewDidAppear()

像这个例子一样展示代码：

if let storyboard = storyboard{
   let vc = storyboard.instantiateViewController(withIdentifier: "GroupProfileViewController") as! GroupProfileViewController
   self.present(vc, animated: true)
}

'故事板 (<UIStoryboard: 0x7b1800030960>) 不包含标识符为 'GroupProfileViewController' 的视图控制器'

'Storyboard (<UIStoryboard: 0x7b1800030960>) doesn't contain a view controller with identifier 'GroupProfileViewController''
