objective-c - iOS5本地通知自定义声音Xcode iOS iPhone Objective-C Xcode

Question

我正在尝试设置自定义本地通知声音，如下所示:

UILocalNotification *notification = [UILocalNotification new];
notification.timeZone = [NSTimeZone systemTimeZone];
notification.fireDate = date;

notification.alertAction = @"123"; 
notification.alertBody = @"123";

//!!!
notification.soundName = @"Glass.aiff";

alarmID=[NSString stringWithFormat:@"%i", arrayAlarms.count];
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:alarmID forKey:@"id"]; 
notification.userInfo = infoDict; 
notification.repeatInterval=NSWeekCalendarUnit;

[[UIApplication sharedApplication] scheduleLocalNotification:notification];

但是我只听到默认声音。我正在ios5上测试应用程序。非常感谢您的事先帮助，对不起我的英语。

自定义通知声音被限制在30秒以内。如果您的声音长于此iOS，则会播放默认声音。这可能是您的问题吗？
