Question

我不断收到此错误：

Implicit use of 'self' in closure; use 'self.' to make capture semantics explicit

即使我将自身放入代码中。请纠正我。

这是我的代码：

@IBAction func doneButton(_ sender: Any) {
    let code = codeTextField.text
    if code == "TEST" || code == "Test" || code == "test" {
        var myAlert = UIAlertController(title:"Alert", message: "You are logging into The Test Zoo, right?", preferredStyle: UIAlertController.Style.alert)
        let yesAction = UIAlertAction(title: "Yes", style: UIAlertAction.Style.default) {
            UIAlertAction in
            performSegue(withIdentifier: "welcomeButton", sender:self)
        }

还有更多，但是yesAction需要更正。

Answer 1

public partial class UserProfile { public long Creater { get; set; } public long Modifier { get; set; } public long Deleter { get; set; } ... ... public virtual User User { get; set; } public virtual User User1 { get; set; } public virtual User User2 { get; set; } }是一种方法，您暗中调用performSegue；显式版本为self。

Answer 2

只需将您的代码行从performSegue(withIdentifier: "welcomeButton", sender:self)更改为self.performSegue(withIdentifier: "welcomeButton", sender:self)

我不断收到这个错误：“在闭包中隐式使用'self'；使用'self'。使捕获语义明确“
