Question

我正在努力获得＆＃34;警报＆＃34;但没有太多运气。

LazyMapCollection<Dictionary<AnyHashable, Any>, AnyHashable>(_base: [AnyHashable("google.c.a.e"): 1, AnyHashable("google.c.a.ts"): 1475009164, AnyHashable("google.c.a.udt"): 0, AnyHashable("gcm.n.e"): 1, AnyHashable("aps"): {
    alert = "test message";
}, AnyHashable("google.c.a.c_id"): 9039575328704479116, AnyHashable("gcm.message_id"): 0:1475009164740581%df6f7f01df6f7f01], _transform: (Function))

这是代码是使用但它无法正常工作

if (userInfo["aps"] != nil) {
                    let msg = (userInfo["alert"] as? String)!
                    let alert1 = UIAlertController(title: "Notification", message: msg, preferredStyle: .alert)
                    alert1.addAction(UIAlertAction(title: "Ok", style: .default, handler: { (action) -> Void in
                    }))
                    self.window?.rootViewController?.present(alert1, animated: true, completion: nil)
                    completionHandler(.newData)
                }

我正在尝试使用值alert的消息显示本地通知。任何想法，将不胜感激。谢谢

这是我的工作解决方案

if (userInfo["aps"] != nil) {
                    if let notification = userInfo["aps"] as? NSDictionary,
                        let alert = notification["alert"] as? String {
                        let alert1 = UIAlertController(title: "Notification", message: alert, preferredStyle: .alert)
                        alert1.addAction(UIAlertAction(title: "Ok", style: .default, handler: { (action) -> Void in
                        }))
                        self.window?.rootViewController?.present(alert1, animated: true, completion: nil)
                        completionHandler(.newData)

                    }
                }
