声音不适用于UINotification

Question

我已经在我的iPad应用中使用了UINotification。我正在尝试将声音添加到我的通知消息中。我尝试了默认和自定义的一个，我已经添加到我的捆绑包中，但两个都无法正常工作。

[[UIApplication sharedApplication] cancelAllLocalNotifications];

UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = nil;
localNotification.alertBody = @"Message";
localNotification.soundName = @"ALERT.mp3";  // UILocalNotificationDefaultSoundName
[[UIApplication sharedApplication] presentLocalNotificationNow:localNotification];

两者都不起作用，我听不到任何声音。

试试这个 并检查您的声音文件是否不应大于30  秒。 在你的app delegate中写下这个

[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];


- (void)scheduleNotification {
    Class cls = NSClassFromString(@"UILocalNotification");
    if (cls != nil) {
            UILocalNotification *notif = [[cls alloc] init]; 
            notif.fireDate = insert your date;
            notif.timeZone = [NSTimeZone localTimeZone];
            notif.alertBody = your message body;
            notif.repeatInterval = 0;
            notif.soundName =  UILocalNotificationDefaultSoundName;
            [[UIApplication sharedApplication] scheduleLocalNotification:notif];
            [notif release];
    }
}
