本地通知 UILocalNotification

1.如果只是纯粹的通知下面的代码就可以实现了

- (void)viewDidLoad {

    [superviewDidLoad];

   ［self  SendLocalNotification］；

}

-(void)SendLocalNotification{

   UILocalNotification *localNotification = [[UILocalNotificationalloc]init];

   //触发通知时间

    localNotification.fireDate = [NSDatedateWithTimeIntervalSinceNow:0.1];

   //重复间隔

   //    localNotification.repeatInterval = kCFCalendarUnitMinute;

    localNotification.timeZone = [NSTimeZonedefaultTimeZone];

    

   //通知内容

    localNotification.alertBody =@"家里老人摔倒了";

    localNotification.applicationIconBadgeNumber =1;

    

    localNotification.soundName =UILocalNotificationDefaultSoundName;

    

   //通知参数

    localNotification.userInfo =@{@"kLocalNotificationKey":@"去吧，皮卡丘"};

    

    localNotification.category =@"kNotificationCategoryIdentifile";

    

    [[UIApplicationsharedApplication]scheduleLocalNotification:localNotification];

}

2.如果还想增加赞和评论的功能继续添加下面代码

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

    

    [selfregisterLocalNotification];

    

   returnYES;

}

- (void)registerLocalNotification

{

   //创建消息上面要添加的动作

   UIMutableUserNotificationAction *action1 = [[UIMutableUserNotificationActionalloc]init];

    action1.identifier =kNotificationActionIdentifileStar;

    action1.title =@"赞";

   //当点击的时候不启动程序，在后台处理

    action1.activationMode =UIUserNotificationActivationModeBackground;

   //需要解锁才能处理(意思就是如果在锁屏界面收到通知，并且用户设置了屏幕锁，用户点击了赞不会直接进入我们的回调进行处理，而是需要用户输入屏幕锁密码之后才进入我们的回调)，如果action.activationMode = UIUserNotificationActivationModeForeground;则这个属性被忽略；

    action1.authenticationRequired =YES;

   /*

     destructive属性设置后，在通知栏或锁屏界面左划，按钮颜色会变为红色

    如果两个按钮均设置为YES，则均为红色（略难看）

    如果两个按钮均设置为NO，即默认值，则第一个为蓝色，第二个为浅灰色

    如果一个YES一个NO，则都显示对应的颜色，即红蓝双色 (CP色)。

     */

    action1.destructive =NO;

    

   //第二个动作

   UIMutableUserNotificationAction *action2 = [[UIMutableUserNotificationActionalloc]init];

    action2.identifier =kNotificationActionIdentifileComment;

    action2.title =@"评论";

   //当点击的时候不启动程序，在后台处理

    action2.activationMode =UIUserNotificationActivationModeBackground;

   //设置了behavior属性为 UIUserNotificationActionBehaviorTextInput的话，则用户点击了该按钮会出现输入框供用户输入

    action2.behavior =UIUserNotificationActionBehaviorTextInput;

   //这个字典定义了当用户点击了评论按钮后，输入框右侧的按钮名称，如果不设置该字典，则右侧按钮名称默认为 “发送”

    action2.parameters =@{UIUserNotificationTextInputActionButtonTitleKey:@"评论"};

    

   //创建动作(按钮)的类别集合

   UIMutableUserNotificationCategory *category = [[UIMutableUserNotificationCategoryalloc]init];

   //这组动作的唯一标示

    category.identifier =kNotificationCategoryIdentifile;

   //最多支持两个，如果添加更多的话，后面的将被忽略

    [categorysetActions:@[action1, action2]forContext:(UIUserNotificationActionContextMinimal)];

   //创建UIUserNotificationSettings，并设置消息的显示类类型

   UIUserNotificationSettings *uns = [UIUserNotificationSettingssettingsForTypes:(UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound)categories:[NSSetsetWithObject:category]];

    

    [[UIApplicationsharedApplication]registerUserNotificationSettings:uns];

}

//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(@"%@", notification.userInfo);

    [selfshowAlertView:@"用户没点击按钮直接点的推送消息进来的/或者该app在前台状态时收到推送消息"];

   NSInteger badge = [UIApplicationsharedApplication].applicationIconBadgeNumber;

    badge -= notification.applicationIconBadgeNumber;

    badge = badge >=0 ? badge :0;

    [UIApplicationsharedApplication].applicationIconBadgeNumber = badge;

}

//在非本App界面时收到本地消息，下拉消息会有快捷回复的按钮，点击按钮后调用的方法，根据identifier来判断点击的哪个按钮，notification为消息内容

- (void)application:(UIApplication *)application handleActionWithIdentifier:(nullableNSString *)identifier forLocalNotification:(UILocalNotification *)notification withResponseInfo:(NSDictionary *)responseInfo completionHandler:(void(^)())completionHandler

{

   if ([identifierisEqualToString:kNotificationActionIdentifileStar]) {

        [selfshowAlertView:@"点了赞"];

    }elseif ([identifierisEqualToString:kNotificationActionIdentifileComment]) {

        [selfshowAlertView:[NSStringstringWithFormat:@"用户评论为:%@", responseInfo[UIUserNotificationActionResponseTypedTextKey]]];

    }

    

    completionHandler();

}

- (void)showAlertView:(NSString *)message

{

   UIAlertController *alert = [UIAlertControlleralertControllerWithTitle:nilmessage:messagepreferredStyle:UIAlertControllerStyleAlert];

   UIAlertAction *action = [UIAlertActionactionWithTitle:@"确定"style:UIAlertActionStyleDefaulthandler:nil];

    [alertaddAction:action];

    [self.window.rootViewControllershowDetailViewController:alertsender:nil];

}

- (void)applicationDidBecomeActive:(UIApplication *)application {

    [UIApplicationsharedApplication].applicationIconBadgeNumber =0;

}
