cordova iOS通知不能在前臺工作

Question

當我的應用程序處於前景時，我正在使用Cordova和插件phonegap-plugin-push， 我沒有看到通知警報。 我需要做什麼？ （我知道在Android平臺上執行此操作的方式（在PushNotification的init方法中設置爲「forceShow」：true），但這僅適用於Android） 預先感謝您的回覆。

丹尼斯，

通知不能在前臺工作。它只能在後臺運行。在前臺處理它需要在委託方法中實現邏輯。 以下是在前臺顯示通知的Objective C代碼片段。

-(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]; 
    }  
} 

它會幫助你解決你的問題。

在iOS中，如果您的應用程序處於前景中，則不會顯示推送通知警報。要實現它，您應該在推送通知接收委託中編寫警報代碼，前提是您的應用程序處於前臺。要知道iOS中的應用程序狀態，這是代碼。

+(BOOL) runningInForeground 
{ 
UIApplicationState state = [UIApplication sharedApplication].applicationState; 

return state == UIApplicationStateActive; 

}

如果妳不想碰iOS原生的東西，那麼你就可以顯示自己的custmize HTML/CSS橫幅（如iOS的推巴納爾）在下面的方法：

push.on('notification', function(data) { 
    If(platform == "iOS" && data.additionalData.foreground){ 
    // Show your Baner here 
// U can also define call back on clicking of that banner 
//Like navigation to respective page or close that banner 
});
