1、增加一个本地推送 //设置20秒之后 NSDate *date = [NSDate dateWithTimeIntervalSinceNow:20]; //chuagjian一个本地推送 UILocalNotification *noti = [[[UILocalNotification alloc] init] autorelease]; if (noti) { //设置推送时间 noti.fireDate = date; //设置时区 noti.timeZone = [NSTimeZone defaultTimeZone]; //设置重复间隔 noti.repeatInterval = NSWeekCalendarUnit; //推送声音 noti.soundName = UILocalNotificationDefaultSoundName; //内容 noti.alertBody = @"推送内容"; //显示在icon上的红色圈中的数子 noti.applicationIconBadgeNumber = 1; //设置userinfo 方便在之后需要撤销的时候使用 NSDictionary *infoDic = [NSDictionary dictionaryWithObject:@"name" forKey:@"key"]; noti.userInfo = infoDic; //添加推送到uiapplication UIApplication *app = [UIApplication sharedApplication]; [app scheduleLocalNotification:noti]; } 2、程序运行时接收到本地推送消息 - (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification*)notification { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"接收到本地提醒 in app" message:notification.alertBody delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil]; [alert show]; //这里,你就可以通过notification的useinfo,干一些你想做的事情了 application.applicationIconBadgeNumber -= 1; } 3、取消一个本地推送 UIApplication *app = [UIApplication sharedApplication]; //获取本地推送数组 NSArray *localArr = [app scheduledLocalNotifications]; //声明本地通知对象 UILocalNotification *localNoti; if (localArr) { for (UILocalNotification *noti in localArr) { NSDictionary *dict = noti.userInfo; if (dict) { NSString *inKey = [dict objectForKey:@"key"]; if ([inKey isEqualToString:key]) { if (localNoti){ [localNoti release]; localNoti = nil; } localNoti = [noti retain]; break; } } } //判断是否找到已经存在的相同key的推送 if (!localNoti) { //不存在 初始化 localNoti = [[UILocalNotification alloc] init]; } if (localNoti && !state) { //不推送 取消推送 [app cancelLocalNotification:localNoti]; [localNoti release]; return; } }
