IOS本地通知

发送通知：  

  UILocalNotification *newNotification = [[UILocalNotification alloc] init];

    if (newNotification) {

//时区

        newNotification.timeZone=[NSTimeZone defaultTimeZone];

//推送事件---10秒后

        newNotification.fireDate=[[NSDate date] dateByAddingTimeInterval:10];

        //推送内容

        newNotification.alertBody = @"信号报警";

//应用右上角红色图标数字

        newNotification.applicationIconBadgeNumber = 1;

注：

//1:格式一定要支持播放，常用的格式caf

//2:音频播放时间不能大于30秒

//3:在Resource里要找到音频文件，倒入时最好能点项目名称右键add导入

        newNotification.soundName = @"jingBao2.caf";

//设置按钮

newNotification.alertAction = @"关闭";

        //判断重复与否

        newNotification.repeatInterval = NSWeekCalendarUnit;

//存入的字典，用于传入数据，区分多个通知 

        NSMutableDictionary *dicUserInfo = [[NSMutableDictionary alloc] init];

        [dicUserInfo setValue:@"" forKey:@"clockID"];

        float floatHeng = userLocation.location.coordinate.latitude;

        float floatShu = userLocation.location.coordinate.longitude;

        [dicUserInfo setValue:[NSString stringWithFormat:@"%f",strX] forKey:@"heng"];

        [dicUserInfo setValue:[NSString stringWithFormat:@"%f",strY] forKey:@"shu"];

        newNotification.userInfo = [NSDictionary dictionaryWithObject:dicUserInfo forKey:@"dictionary"];

        [dicUserInfo release];

        [[UIApplication sharedApplication] scheduleLocalNotification:newNotification];

    }

    NSLog(@"Post new localNotification:%@", newNotification);

    [newNotification release];

    [pool release];

取消通知：

通知完一定要取消，IOS最多允许最近本地通知数量是64个，超过限制的本地通知将被忽略。

1：删除应用所有通知

[[UIApplication sharedApplication] cancelAllLocalNotifications];

2：根据字典删除个别通知 

key:发送通知时候传入的字典值来判断是哪个推送

    for (int i=0; i<[myArray count]; i++) {

        UILocalNotification    *myUILocalNotification=[myArray objectAtIndex:i];

        if ([[[myUILocalNotification userInfo] objectForKey:@"key"] intValue]==@"字典值") {

            [[UIApplication sharedApplication] cancelLocalNotification:myUILocalNotification];

        }

    }

通知执行完调用的方法 AppDelegate.m类里面

//推送完 执行的事件

-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{

//notification是发送通知时传入的字典信息

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"标题" message:notification.alertBody delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil];

        [alert show];

[alert release];

}

最后还有一个地方：执行通知一定要退出应用才能收到通知。
