iphone - iOS 我可以在应用程序处于前台时使用本地通知播放声音吗

Question

当应用程序处于前台时，本地通知声音未播放：我使用了以下代码

UILocalNotification *notif = [[cls alloc] init];
notif.fireDate = [datePicker date];         
notif.timeZone = [NSTimeZone defaultTimeZone];
notif.alertBody = @"Did you forget something?";
notif.alertAction = @"Show me";
notif.soundName = @"step.mp3";//UILocalNotificationDefaultSoundName;
notif.applicationIconBadgeNumber = 1;

NSDictionary *userDict = [NSDictionary dictionaryWithObject:reminderText.text
                                                                 forKey:kRemindMeNotificationDataKey];
notif.userInfo = userDict;

[[UIApplication sharedApplication] scheduleLocalNotification:notif];
[notif release];

Answer 1

UILocalNotification *localNotification = [[UILocalNotification alloc]init];

   // Set the notification time.
    localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:10];

   // You can specify the alarm sound here.
   localNotification.soundName = UILocalNotificationDefaultSoundName;
   //OR
   localNotification.soundName = @"sound.caf";

   // Set the alertbody of the notification here.
    localNotification.alertBody = @"Test Alert";

   // Create the buttons on the notification alertview.
    localNotification.alertAction = @"View";

   // You can also specify custom dictionary to store informations
    NSDictionary *infoDict = [NSDictionary dictionaryWithObject:@"alarm#2" forKey:@"notifiKey"];
    localNotification.userInfo = infoDict;

    //Repeat the notification.
    localNotification.repeatInterval = NSDayCalendarUnit;

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