本地通知"didReceiveLocalNotification"调用两次

Question

我使用以下方式处理本地通知:

- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif

并安排本地通知:

- (void)scheduleNotificationWithInterval:(int)minutesBefore {
    UILocalNotification *localNotif = [[UILocalNotification alloc] init];

    if (localNotif == nil)
        return;

    NSDate *fireDate = [NSDate date];
    localNotif.fireDate = [fireDate dateByAddingTimeInterval:minutesBefore*60];
    localNotif.timeZone = [NSTimeZone defaultTimeZone];
    localNotif.repeatInterval = kCFCalendarUnitMinute;
    localNotif.alertBody = [NSString stringWithFormat:NSLocalizedString(@"LocalEvent notification in %i minutes.", nil),minutesBefore];
    localNotif.alertAction = NSLocalizedString(@"View Details", nil);
    localNotif.applicationIconBadgeNumber = 1;

    NSDictionary *infoDict = [NSDictionary dictionaryWithObjectsAndKeys:@"This is dict, you can pass info for your notification",@"info",nil];
    localNotif.userInfo = infoDict;

    [[UIApplication sharedApplication] scheduleLocalNotification:localNotif];

    [localNotif release];
    NSLog(@"Event scheduled");
}

当我收到通知时,didReceiveLocalNotification:会被叫两次.

难道我做错了什么？

请帮忙.

谢谢.

我认为模拟器中存在一个已知错误,它会两次触发委托通知方法.它不应该发生在设备上,不管是否与XCode相连.

我也面临同样的问题,我找到的解决方案是在didReceiveLocalNotification中编写此代码

if (state == UIApplicationStateActive) {
    NSLog(@"UIApplicationStateActive"); 
}
else if(state == UIApplicationStateInactive){
    NSLog(@"UIApplicationStateInActive");
}

在这些情况下,我只是编写代码,我希望我的应用程序在通知,活动模式和非活动模式下执行
