更改已设置的UILocalNotification的声音名称

Question

对于尚未创建的通知（新通知）更改，但对于已创建的通知，先前的声音保留。

我曾尝试：

NSString *soundName = cell.titleLabel.text; 

NSArray *notifications = [[UIApplication sharedApplication] scheduledLocalNotifications]; 

for (UILocalNotification *notif in notifications) { 
    notif.soundName = [NSString stringWithFormat:@"%@.mp3", soundName]; 
} 

，但它不工作...

你必须重新安排您安排的通知。但请确保您删除了您之前预定的那些。

NSArray *notifications = [[UIApplication sharedApplication] scheduledLocalNotifications]; 
[[UIApplication sharedApplication] cancelAllLocalNotifications]; 

for (UILocalNotification *notif in notifications) { 
    notif.soundName = [NSString stringWithFormat:@"%@.mp3", soundName]; 
    [[UIApplication sharedApplication] scheduleLocalNotification:notification]; 
}
