本地通知UILocalNotification

本地推送UILocalNotification

• 获取每天的9点的时间NSDate
  NSDate *date = [NSDate date];
  NSTimeZone *gmt = [NSTimeZone systemTimeZone];
  NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar];
  [gregorian setTimeZone:gmt];
  NSDateComponents *components = [gregorian components: NSUIntegerMax fromDate: date];
  [components setHour:9];
  [components setMinute:0];
  [components setSecond: 0];
  NSDate *newDate = [gregorian dateFromComponents:components];
• 增加一个本地推送

  notification.fireDate = newDate; 设置推送时间
  notification.timeZone=[NSTimeZone defaultTimeZone];设置时区
  notification.soundName = UILocalNotificationDefaultSoundName;推送声音
  noti.applicationIconBadgeNumber = 1;显示在icon上的红色圈中的数子
  NSDictionary *infoDic = [NSDictionary dictionaryWithObject:@"name" forKey:@"key"];
  noti.userInfo = infoDic;设置userinfo 方便在之后需要撤销的时候使用
  notification.repeatInterval = kCFCalendarUnitDay;设置重复间隔
  notification.alertBody = @"推送内容";
  [[UIApplication sharedApplication] scheduleLocalNotification:notification];添加推送到UIApplication

• 程序运行时接收到本地推送消息
  -(void)application:(UIApplication )application didReceiveLocalNotification:(UILocalNotification)notification{
  UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"接收到本地提醒 in app" message:notification.alertBody delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];
  [alertView 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;
  }
• 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;
  }
