ImusingUILocalNotificationinanapplication.我在应用程序中使用UILocalNotification。Intheapplicationt
I'm using UILocalNotification in an application.
我在应用程序中使用UILocalNotification。
In the application there are two sounds which are played conditionally- I have applied proper conditions for them.
在应用程序中有两种声音有条件地播放 - 我已经为它们应用了适当的条件。
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.
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，但声音不会在应用程序中播放。
Code is given below to set the notification:
下面给出了代码来设置通知：
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];
What I have checked for is the Sound setting in the Settings/Notification Centre app for my app.
我检查过的是我的应用程序的设置/通知中心应用程序中的声音设置。
Please go through 1st to 3rd image to see what I have checked.
请查看第1张到第3张图片以查看我查看过的内容。
(1) Notification Center
（1）通知中心
(2) Application
（2）申请
(3) Sound is off here
（3）声音在这里关闭
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.
因此，为了启用此功能，我已在应用程序的目标功能中检查了Inter App Audio，它已关闭，如下图所示。
Capabilities in Inter-app audio
应用间音频的功能
Then I have changed it to On and it looks like shown in the image below.
然后我将其更改为On，它看起来如下图所示。
Yet, it still does not play any sound in iOS 7 devices.
然而，它仍然没有在iOS 7设备中播放任何声音。
Does anybody have any idea about why is it not working? It would be a great help.
有没有人知道它为什么不起作用？这将是一个很大的帮助。
Thanks.
谢谢。
