UILocalNotification 自定义声音未在 iOS7 中播放 [英] UILocalNotification custom sound is not playing in iOS7

问题描述

我在应用程序中使用 UILocalNotification.

I'm using UILocalNotification in an application.

在应用程序中有两种有条件播放的声音 - 我为它们应用了适当的条件.

In the application there are two sounds which are played conditionally- I have applied proper conditions for them.

但是当我安装应用程序并在 iOS 7 设备上运行它时，它会触发本地通知，但应用程序中没有播放声音.

But when I install the application and run it on an iOS 7 device, then it fires the local notification but a sound is not playing in the application.

下面给出了设置通知的代码:

Code is given below to set the notification:

    UILocalNotification *localNotification = [[UILocalNotification alloc] init];
    if (localNotification == nil)
        return;
    localNotification.fireDate = [pickerView date];

    localNotification.timeZone = [NSTimeZone defaultTimeZone];

    if (alarm_number == 1) {
        localNotification.alertBody = [NSString stringWithFormat:@"First Alarm"];
    }
    else
    {
        localNotification.alertBody = [NSString stringWithFormat:@"Second Alarm"];
    }

    localNotification.alertAction =@"Ok";

    NSString *message = [[NSString alloc]initWithString:@""];

    if(alarm_number == 1)
    {
        localNotification.soundName=@"Alarm_1.mp3";
        message = @"First Alarm Scheduled";
    }
    else
    {
        localNotification.soundName=@"Alarm_2.mp3";
        message = @"Second Alarm Scheduled";
    }

    localNotification.applicationIconBadgeNumber = 1;

    // Specify custom data for the notification
    NSString *alarmString;
    if (alarm_number==1) {
        alarmString = [NSString stringWithFormat:@"First Alarm"];
    }
    else
    {
        alarmString = [NSString stringWithFormat:@"Second Alarm"];
    }

    NSDictionary *infoDict = [NSDictionary dictionaryWithObject:alarmString forKey:@"AlarmFor"];

    localNotification.userInfo = infoDict;

    // Schedule the notification
    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
    [localNotification release];

我检查的是我的应用的设置/通知中心应用中的声音设置.

What I have checked for is the Sound setting in the Settings/Notification Centre app for my app.

请查看第一到第三张图片，看看我检查了什么.

Please go through 1st to 3rd image to see what I have checked.

(1) 通知中心

(2) 申请

(3) 这里没有声音

因此，为了启用此功能，我在应用程序的目标中的 Capabilities 处检查了应用间音频，并且如下图所示关闭.

So, to enable this I have checked Inter App Audio at Capabilities in Targets of the application and it was Off as shown in the image below.

应用间音频功能

然后我将其更改为开，如下图所示.

Then I have changed it to On and it looks like shown in the image below.

然而，它仍然无法在 iOS 7 设备中播放任何声音.

Yet, it still does not play any sound in iOS 7 devices.

有人知道为什么它不起作用吗?这将是一个很大的帮助.

Does anybody have any idea about why is it not working? It would be a great help.

谢谢.

推荐答案

您是否尝试关闭请勿打扰"模式?我有同样的问题，然后我发现请勿打扰"已开启.关闭后，一切正常.

Did you try to turn off "Do not disturb" mode off? I have the same problem, then I found out "Do not Disturb" is on. After turn off that, it all works the right way.
