以自定义时间间隔显示本地通知

Question

我是iphone新手，我正在使用下面的代码，在这里本地通知不会在10秒内触发以及重复间隔也不起作用，它不会在每个通知中显示second.After1分钟firedate通话和以同样的方式重复间隔适用于每一个minute.how可以设置重复间隔为每15 sec.If有人知道这个请大家帮我...

- (void)applicationDidEnterBackground:(UIApplication *)application { 
    NSLog(@"1"); 

    NSTimeInterval interval = 10; 
    NSDate *alertTime = [NSDate dateWithTimeIntervalSinceNow:interval]; 
    UIApplication* app = [UIApplication sharedApplication]; 
    UILocalNotification* notifyAlarm = [[UILocalNotification alloc] init]; 
    if (notifyAlarm){ 
     notifyAlarm.fireDate = alertTime; 

     notifyAlarm.alertAction = @"Message"; 
     notifyAlarm.alertBody = @"Alert"; 
     notifyAlarm.hasAction = YES; 
     notifyAlarm.timeZone = [NSTimeZone defaultTimeZone]; 

     notifyAlarm.repeatInterval = NSSecondCalendarUnit; 
     // timer = [[NSTimer alloc]initWithFireDate:alertTime interval:interval target:self selector:@selector(sendRequest) userInfo:nil repeats:YES]; 

     [app scheduleLocalNotification:notifyAlarm]; 

     }

您需要在appDelegate中实现这个功能，以便通知在应用程序运行时工作。

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification { 
    //do something 
}
