以自定义时间间隔显示本地通知

Question

我是iphone的新手。我正在使用下面的代码，这里本地通知不会在10秒内触发，重复间隔也不起作用，它不会在每秒显示通知.1分钟后拨打电话并以相同的方式重复间隔每隔一分钟工作。如何重复间隔设置为每15秒。如果有人知道这一点，请帮助我...

- (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中实现此功能，以便在应用运行时通知正常工作。

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