Question

嗨我正在尝试在我的iDevice上接收推送通知时播放默认的推送声音我使用此代码播放

中的声音

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo` Method 

NSDictionary *test =(NSDictionary *)[userInfo objectForKey:@"aps"];
    NSString *alertString =(NSString *) [test objectForKey:@"alert"];
    NSLog(@"String recieved: %@",alertString);
    if (state == UIApplicationStateActive) {
            UIAlertView *alertmessage=[[UIAlertView alloc]initWithTitle:@"iEverything Tech"
                                                                message:alertString                                                    delegate:self
                                               cancelButtonTitle:@"OK"
                                               otherButtonTitles:nil];


            [alertmessage show];

            AudioServicesPlaySystemSound(1002);


        }

        if (state == UIApplicationStateInactive) {
            AudioServicesPlaySystemSound(1002);
        }

        if (state == UIApplicationStateBackground) {
            AudioServicesPlaySystemSound(1002);
        }

我的第二个问题是如何在AlertView中显示Pushed消息？

感谢您的回答！

我不能像Parse一样使用Push提供程序，因为我们需要自动推送服务器

Answer 1

您必须使用推送通知有效负载播放声音。阅读apple doc。 enter image description here

Answer 2

与NSEncoder写的一样，声音必须在通知有效载荷中。要回答第二个问题，您的通知将显示在警告，徽章或根本不显示 - 取决于用户通知设置中的设置，您对此没有任何影响。

Answer 3

尝试此操作以检索通知消息，并且下面的“alertString”保留收到的消息

NSDictionary *test =(NSDictionary *)[userInfo objectForKey:@"aps"];
NSString *alertString =(NSString *) [test objectForKey:@"alert"];
NSLog(@"String recieved: %@",alertString);

Answer 4

只需将字符串传递到将要执行的警报

NSDictionary *test =(NSDictionary *)[userInfo objectForKey:@"aps"];
NSString *alertString =(NSString *) [test objectForKey:@"alert"];
NSLog(@"String recieved: %@",alertString);
UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:@"Title" message:alertString delegate:self cancelButtonTitle:@"OK" otherButtonTitles: @"Not OK", nil] autorelease];
[alert show];

Answer 5

在您的“应用程序didfinishlaunchingwithoptions中添加以下内容

NSDictionary *remoteNotif = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey];
if (remoteNotif) {
    [self handleRemoteNotification:application userInfo:remoteNotif];
    [[UIApplication sharedApplication] cancelAllLocalNotifications];
    [UIApplication sharedApplication].applicationIconBadgeNumber--;        
}

当您通过远程通知打开应用程序时，通过点击通知，这将减少徽章编号，如果您想在用户打开应用程序时删除徽章编号，那么只需在条件下执行代码，如果条件在这里只需通过点击远程通知来检查应用程序是否已打开..，

Answer 6

要在iOS中播放通知的默认声音，您需要将以下代码添加到有效负载json

"sound" : "default"

所以，你＆＃34;通知＆＃34;有效载荷应该类似于：

 "notification": {
        "title": "4x8",
        "body": "15:16.2342",
        "message":"https://www.google.com",
        "sound" : "default"
      }
