应用程序打开时的iOS应用程序通知（如whatsapp）

我实际上接收到带有JSON和消息的通知，所以我想要的是处理该通知并将其显示给用户

当应用程序未运行或处于后台时，会显示消息，但当应用程序打开时，不会显示任何通知。事实上，我在

didReceiveMemotentification

中收到json，但我想要的是一个类似whatsapp的通知框

像这样：

我有这个：

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
    print("Notification received: \(userInfo)")
    let notification = userInfo["aps"] as? NSDictionary
    let message = notification?.valueForKey("alert")
}

这是“didfinishlaunchWithOptions”

let readAction = UIMutableUserNotificationAction()
        readAction.identifier = "READ_IDENTIFIER"
        readAction.title = "Read"
        readAction.activationMode = UIUserNotificationActivationMode.Foreground
        readAction.destructive = false
        readAction.authenticationRequired = true

        let deleteAction = UIMutableUserNotificationAction()
        deleteAction.identifier = "DELETE_IDENTIFIER"
        deleteAction.title = "Delete"
        deleteAction.activationMode = UIUserNotificationActivationMode.Foreground
        deleteAction.destructive = true
        deleteAction.authenticationRequired = true

        let ignoreAction = UIMutableUserNotificationAction()
        ignoreAction.identifier = "IGNORE_IDENTIFIER"
        ignoreAction.title = "Ignore"
        ignoreAction.activationMode = UIUserNotificationActivationMode.Foreground
        ignoreAction.destructive = false
        ignoreAction.authenticationRequired = false

        let messageCategory = UIMutableUserNotificationCategory()
        messageCategory.identifier = "MESSAGE_CATEGORY"
        messageCategory.setActions([readAction, deleteAction], forContext: UIUserNotificationActionContext.Minimal)
        messageCategory.setActions([readAction, deleteAction, ignoreAction], forContext: UIUserNotificationActionContext.Default)

        let types: UIUserNotificationType = [UIUserNotificationType.Badge, UIUserNotificationType.Sound, UIUserNotificationType.Alert]

        application.registerUserNotificationSettings(
            UIUserNotificationSettings(
                forTypes: types,
                categories: (NSSet(array: [messageCategory])) as? Set<UIUserNotificationCategory>))

        UIApplication.sharedApplication().registerForRemoteNotifications()

        let notTypes:UIUserNotificationType = [UIUserNotificationType.Alert, UIUserNotificationType.Badge, UIUserNotificationType.Sound]
        let noteSettings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: notTypes, categories: nil)

        UIApplication.sharedApplication().registerUserNotificationSettings(noteSettings)

let readAction=UIMutableUserNotificationAction（）
readAction.identifier=“读取标识符”
readAction.title=“读取”
readAction.activationMode=UIUserNotificationActivationMode.前台
readAction.com=false
readAction.authenticationRequired=true
让deleteAction=UIMutableUserNotificationAction（）
deleteAction.identifier=“删除\u标识符”
deleteAction.title=“删除”
deleteAction.activationMode=UIUserNotificationActivationMode.Foreground
deleteAction.deleteAction=true
deleteAction.authenticationRequired=true
让ignoreAction=UIMutableUserNotificationAction（）
ignoreAction.identifier=“忽略\u标识符”
ignoreAction.title=“忽略”
ignoreAction.activationMode=UIUserNotificationActivationMode.前台
ignoreAction.destromical=false
ignoreAction.authenticationRequired=false
让messageCategory=UIMutableUserNotificationCategory（）
messageCategory.identifier=“消息\类别”
messageCategory.setActions（[readAction，deleteAction]，forContext:UIUserNotificationActionContext.Minimal）
messageCategory.setActions（[readAction，deleteAction，ignoreAction]，forContext:UIUserNotificationActionContext.Default）
let类型：UIUserNotificationType=[UIUserNotificationType.Badge，UIUserNotificationType.Sound，UIUserNotificationType.Alert]
application.registerUserNotificationSettings(
UIUserNotificationSettings(
forTypes：类型，
类别：（NSSet（数组：[messageCategory]）作为？集合）
UIApplication.sharedApplication（）.registerForRemoteNotifications（）
let notTypes:UIUserNotificationType=[UIUserNotificationType.Alert，UIUserNotificationType.Badge，UIUserNotificationType.Sound]
let-noteSettings:UIUserNotificationSettings=UIUserNotificationSettings（forTypes:notTypes，categories:nil）
UIApplication.sharedApplication（）.registerUserNotificationSettings（noteSettings）

希望有人能帮忙。感谢您所做的一切

您只需创建一个视图，使用您的内容对其进行自定义，并在应用程序窗口中显示即可

---

还有一些框架可以为您做到这一点，比如当您的应用程序位于前台时，iOS将不会显示通知横幅。你必须展示你自己。您可以使用其中一些第三代码来显示横幅，并处理横幅上的触摸以处理相应的代码：

在回拨DidReceiveMotonification中，检查应用程序状态：

if ( application.applicationState == UIApplicationStateActive ) {
// show your banner
}

---

您不需要使用其他框架或库。在iOS 10中，您可以使用方法

userNotificationCenter（ux0:willPresent:withCompletionHandler:）

只有将属性

content available:1

添加到有效负载时，才会调用此方法。有效载荷应类似于：

{
     "aps":{
          "alert":"Testing.. (7)",
          "badge":1,"sound":"default"
     },
     "content-available":1
}

试着把你的问题改写成“我有一个字符串，我想把它放在标签上”。
