swift - 如何在 Swift 中销毁单例

Question

如何在 Swift 中销毁单例？

我这样创建一个单例:

class MyManager  {
    private static let sharedInstance = MyManager()
    class var sharedManager : MyManager {
        return sharedInstance
    }
}

只是一个关于如何处理单例的当前实例的简单示例:

import UIKit

class AnyTestClass
{
    struct Static
    {
        private static var instance: AnyTestClass?
    }

    class var sharedInstance: AnyTestClass
    {
        if Static.instance == nil
        {
            Static.instance = AnyTestClass()
        }

        return Static.instance!
    }

    func dispose()
    {
        AnyTestClass.Static.instance = nil
        print("Disposed Singleton instance")
    }

    func saySomething()
    {
        print("Hi")
    }

}

// basic usage
AnyTestClass.sharedInstance.saySomething()
AnyTestClass.sharedInstance.dispose()

希望对您有所帮助。
