Я пытаюсь отправить данные между двумя классами через MultipeerConnectivity. Я пытаюсь сделать это с помощью методов делегата.
Я определил этот протокол:
protocol AssetDelegate {
func changeThisName(data: Data)
}
Мой основной ViewController — это AssetDelegate, и я реализовал эту функцию просто так:
func changeThisName(data: Data) {
print("changeThisName called")
if let image = UIImage(data: data) {
imageViewAsset.image = image
}
}
Это просто для того, чтобы увидеть, можно ли полученное изображение декодировать и назначить элементу пользовательского интерфейса imageViewAsset.
Этот метод вызывается внутри определенного мной класса «Менеджер» MultipeerConnectivity, который имеет экземпляр в AppDelegate (это определение «одиночки»?)
Мой класс «MPCManager» имеет различные методы делегата MCSession, в частности метод сеанса (didReceive: data), который:
var assetDelegate: AssetDelegate?
func session(_ session: MCSession, didReceive data: Data, fromPeer peerID: MCPeerID) {
print("Data Recieved: \(data)")
self.assetDelegate?.changeThisName(data: data)
}
Я вижу print("Data Received:(data)") в журнале консоли. Но я не вижу оператор печати метода changeThisName.
Это вывод журнала консоли. По сути, есть 2 строки, показывающие подключение MPC («другое состояние» и «сеанс подключен»). Затем идут 2 пункта «Полученные данные».
