iPhone闹钟的问题？
为什么我用UIlocalNotification做的闹钟，就是没有声音呢？
贴上代码：
- (void)viewDidLoad{ [super viewDidLoad]; //发送通知 UILocalNotification *notification=[[UILocalNotification alloc] init]; if (notification!=nil) { NSDate *now=[NSDate new]; notification.fireDate=[now dateByAddingTimeInterval:10];//10秒后通知 notification.repeatInterval=kCFCalendarUnitWeekday;//循环次数，kCFCalendarUnitWeekday一周一次 notification.timeZone=[NSTimeZone defaultTimeZone]; notification.applicationIconBadgeNumber=1; //应用的红色数字 notification.soundName= UILocalNotificationDefaultSoundName;//声音，可以换成alarm.soundName = @"myMusic.caf" //去掉下面2行就不会弹出提示框 notification.alertBody=@"通知内容";//提示信息 弹出提示框 notification.alertAction = @"打开"; //提示框按钮 //notification.hasAction = NO; //是否显示额外的按钮，为no时alertAction消失 // NSDictionary *infoDict = [NSDictionary dictionaryWithObject:@"someValue" forKey:@"someKey"]; //notification.userInfo = infoDict; //添加额外的信息 [[UIApplication sharedApplication] scheduleLocalNotification:notification]; } [notification release];}
