在UILocalNotification中如何爲聲音屬性添加系統聲音文件不是自定義聲音

Question

自定義文件我們可以添加到localNotification但我的要求是從System/Library/Audio/UISounds/New/路徑聲音文件。需要爲每個用戶選擇

Answer 1

這是非常簡單的玩法：

我已經編輯我的代碼：

只需添加路徑NSURL，然後將該網址添加到AVAudioPlayer。呼叫play方法

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/ma.mp3", [[NSBundle mainBundle] resourcePath]]]; 

    NSError *error; 
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error]; 
    audioPlayer.numberOfLoops = -1; 

[audioPlayer play]; 


} 

添加默認聲音uilocalnotification

- (void)scheduleNotification { 

    [reminderText resignFirstResponder]; 
    [[UIApplication sharedApplication] cancelAllLocalNotifications]; 

    Class cls = NSClassFromString(@"UILocalNotification"); 
    if (cls != nil) { 

    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 = UILocalNotificationDefaultSoundName; 
    notif.applicationIconBadgeNumber = 1; 

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

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