在前臺iOS中的App時獲取推送通知我在我的應用程序中使用推送通知服務。當應用程序在后臺時，我能夠在通知屏幕上看到通知（當我們從iOS設備的頂部向下滑動時顯示的屏幕）。但是如果應用程序在前臺是委托方法- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo正在調用，但通知屏幕中不顯示通知。我想在通知屏幕上顯示通知，無論應用程序是在后臺還是前臺。我厭倦了尋找解決方案。任何幫助是極大的贊賞。

要在應用程序位于前臺時顯示橫幅消息，請使用以下方法。
iOS 10，Swift 3/4：
// This method will be called when app received push notifications in foregroundfunc userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.alert, .badge, .sound])}iOS 10，Swift 2.3：
@available(iOS 10.0, *)func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void){
//Handle the notification
completionHandler(
[UNNotificationPresentationOptions.Alert,
UNNotificationPresentationOptions.Sound,
UNNotificationPresentationOptions.Badge])}您還必須將您的應用代表注冊為通知中心的代表：
import UserNotifications// snip!class AppDelegate : UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate// snip!
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// set the delegate in didFinishLaunchingWithOptions
UNUserNotificationCenter.current().delegate = self ...
}

下面的代碼將適合您：
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
application.applicationIconBadgeNumber = 0;
//self.textView.text = [userInfo description];
// We can determine whether an application is launched as a result of the user tapping the action
// button or whether the notification was delivered to the already-running application by examining
// the application state.
if (application.applicationState == UIApplicationStateActive) {
// Nothing to do if applicationState is Inactive, the iOS already displayed an alert view.
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Did receive a Remote Notification" message:[NSString stringWithFormat:@"Your App name received this notification while it was running:\n%@",[[userInfo objectForKey:@"aps"] objectForKey:@"alert"]]delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alertView show];
} }

對于任何可能感興趣的人，我最終創建了一個自定義視圖，看起來像頂部的系統推送橫幅，但添加了一個關閉按鈕（小藍色X）和一個選項來點擊消息進行自定義操作。它還支持在用戶有時間讀取/解除舊通知之前到達多個通知的情況（沒有限制可以堆積多少...）
鏈接到GitHub：AGPushNote
用法基本上是在線：
[AGPushNoteView showWithNotificationMessage:@"John Doe sent you a message!"];
它在iOS7上看起來像這樣（iOS6具有iOS6的外觀和感覺......）
