NSNotification.Name+Extension

1. 首先添加key到NSNotification.Name的延展文件中

extension NSNotification.Name {
    
    static let LoginSuccess = NSNotification.Name("LoginSuccess")
}

2. 使用

// 发送通知
NotificationCenter.default.post(name: .LoginSuccess, object: nil)

// 接收通知
NotificationCenter.default.addObserver(self, selector: #selector(enterFirstPage(notification:)), name: .LoginSuccess, object: nil)
