我正在尝试从 appdelegate 发布通知 NotificationCenter 并在另一个视图中接收通知，但未收到通知。
发布通知：-
func xmppStream(_ sender: XMPPStream, didReceive message: XMPPMessage)
{
print("did receive message isss-->\(message)")
NotificationCenter.default.post(name: Notification.Name("MessageReceived"), object: message)
}
在 viewdidload 中收到通知：-
NotificationCenter.default.addObserver(self, selector: #selector(self.messagereceived(notification:)), name: Notification.Name("MessageReceived"), object: nil)
方法 ：-
@objc func messagereceived(notification:Notification)
{
let message = notification.object as? XMPPMessage
print("chat conversion message is----->\(message)")
}
My "收到消息“ 方法未调用。
所以任何人有与此相关的解决方案请帮助我。
提前致谢。
更改通知帖子
NotificationCenter.default.post(name: Notification.Name("MessageReceived"), object: message)
to
NotificationCenter.default.post(Notification(name: Notification.Name(rawValue: "MessageReceived"),object: message))
和观察者从
NotificationCenter.default.addObserver(self, selector: #selector(self.messagereceived(notification:)), name: Notification.Name("MessageReceived"), object: nil)
to
NotificationCenter.default.addObserver(self, selector: #selector(self.messagereceived(notification:)), name: NSNotification.Name(rawValue: "MessageReceived"), object: nil)
