在前台iOS中的App时获取推送通知我在我的应用程序中使用推送通知服务。当应用程序在后台时,我能够在通知屏幕上看到通知(当我们从iOS设备的顶部向下滑动时显示的屏幕)。但是如果应用程序在前台是委托方法- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo正在调用,但通知屏幕中不显示通知。我想在通知屏幕上显示通知,无论应用程序是在后台还是前台。我厌倦了寻找解决方案。任何帮助是极大的赞赏。

要在应用程序位于前台时显示横幅消息,请使用以下方法。
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])}
您还必须将您的应用代表注册为通知中心的代表:
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 ... }

下面的代码将适合您:
- (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]; } }

对于任何可能感兴趣的人,我最终创建了一个自定义视图,看起来像顶部的系统推送横幅,但添加了一个关闭按钮(小蓝色X)和一个选项来点击消息进行自定义操作。它还支持在用户有时间读取/解除旧通知之前到达多个通知的情况(没有限制可以堆积多少...)
链接到GitHub:AGPushNote
用法基本上是在线:
[AGPushNoteView showWithNotificationMessage:@"John Doe sent you a message!"];
它在iOS7上看起来像这样(iOS6具有iOS6的外观和感觉......)
