iOS-本地推送（本地通知）

第一步：注册本地通知：

// 设置本地通知
+ (void)registerLocalNotification:(NSInteger)alertTime {
  UILocalNotification *notification = [[UILocalNotification alloc] init];
  // 设置触发通知的时间
  NSDate *fireDate = [NSDate dateWithTimeIntervalSinceNow:alertTime];
  NSLog(@"fireDate=%@",fireDate);  

  notification.fireDate = fireDate;
  // 时区
  notification.timeZone = [NSTimeZone defaultTimeZone];
  // 设置重复的间隔
  notification.repeatInterval = kCFCalendarUnitSecond;  

  // 通知内容
  notification.alertBody =  @"该起床了...";
  notification.applicationIconBadgeNumber = 1;
  // 通知被触发时播放的声音
  //notification.soundName = UILocalNotificationDefaultSoundName;  //默认声音
  notification.soundName = @"LocalNotificationMusic.m4r";//播放音乐
  // 通知参数
  NSDictionary *userDict = [NSDictionary dictionaryWithObject:@"开始学习iOS开发了" forKey:@"key"];
  notification.userInfo = userDict;  

  // ios8后，需要添加这个注册，才能得到授权
   NSString *system = [[ICDeviceInfoHelper shareInstant]getDeviceSystemVersion];
    NSInteger systemInt = [system floatValue];
    if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)] && systemInt >= 8) {
    UIUserNotificationType type =  UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound;
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:type                                                                       categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
    // 通知重复提示的单位，可以是天、周、月
    notification.repeatInterval = NSCalendarUnitDay;
  } else {
    // 通知重复提示的单位，可以是天、周、月
    notification.repeatInterval = NSDayCalendarUnit;
  }  

  // 执行通知注册
  [[UIApplication sharedApplication] scheduleLocalNotification:notification];
}  

第二步：处理通知，这个是在appdelegate中的代理 方法回调

这里氛围两种情况

1. 当app没有关闭, 进入后台运行时, 通过本地通知途径进入app, 将触发application: didReceiveLocalNotification方法.

2. 当app关闭时, 通过本地通知途径进入app, 不会触发application: didReceiveLocalNotification方法. 需要通过application: didFinishLaunchingWithOptions:方法, 判断是否由本地通知打开app.(具体方法见代码)

当app没有关闭(后台运行), 调用本地通知启动

// 本地通知回调函数，当应用程序在前台时调用
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
  NSLog(@"noti:%@",notification);  

  // 这里真实需要处理交互的地方
  // 获取通知所带的数据
  NSString *notMess = [notification.userInfo objectForKey:@"key"];
  UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"本地通知(前台)"
                                                  message:notMess
                                                 delegate:nil
                                        cancelButtonTitle:@"OK"
                                        otherButtonTitles:nil];
  [alert show];  

  // 更新显示的徽章个数
  NSInteger badge = [UIApplication sharedApplication].applicationIconBadgeNumber;
  badge--;
  badge = badge >= 0 ? badge : 0;
  [UIApplication sharedApplication].applicationIconBadgeNumber = badge;  

  // 在不需要再推送时，可以取消推送
  [HomeViewController cancelLocalNotificationWithKey:@"key"];
}  

当app关闭, 调用本地通知启动

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    //app启动时,其他代码
    [self otherCode];

    /*本地通知方式-启动*/
    //获取本地通知,如果不是本地通知方式启动, notification将为nil
    UILocalNotification *notification = [launchOptions objectForKey: UIApplicationLaunchOptionsLocalNotificationKey];
    if (notification && [notification isKindOfClass:[UILocalNotification class]]) {
        //获取本地通知详细信息
        NSDictionary *userInfo = notification.userInfo;
        //通过信息判断为哪条本地通知, 做出相应回应
        NSString *name = [userInfo objectForKey:@"name"];
        if ([name isEqualToString:@"remindNotification"]) {
                //做出反应
                [self actionCode];
            }
        }

    return YES;
}

取消某个本地通知

// 取消某个本地推送通知
+ (void)cancelLocalNotificationWithKey:(NSString *)key {
  // 获取所有本地通知数组
  NSArray *localNotifications = [UIApplication sharedApplication].scheduledLocalNotifications;  

  for (UILocalNotification *notification in localNotifications) {
    NSDictionary *userInfo = notification.userInfo;
    if (userInfo) {
      // 根据设置通知参数时指定的key来获取通知参数
      NSString *info = userInfo[key];  

      // 如果找到需要取消的通知，则取消
      if (info != nil) {
        [[UIApplication sharedApplication] cancelLocalNotification:notification];
        break;
      }
    }
  }
}  

本地推送-应用角标自加

如果利用一个本地推送对象，设置为每天重复，图标的数量始终会一直不变；图标累加需要设置多个本地推送基于不同才场景进行设置。
