iOS 本地消息通知推送

一. 打开项目推送开关

二. 注册通知

1. 先导入头文件#import <UserNotifications/UserNotifications.h>

如果你的工程年代久远，导入会报错，就需要导入框架，见图。

2. 注册通知

• 区分iOS 10.0 以前和以后进行注册

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    if (@available(iOS 10.0, *)) {

        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
        center.delegate = self;
        [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert + UNAuthorizationOptionSound)
                              completionHandler:^(BOOL granted, NSError * _Nullable error) {
                              }];
        [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
        }];

    } else {
        
        if ([UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)]){
            [[UIApplication sharedApplication] registerUserNotificationSettings:
             [UIUserNotificationSettings settingsForTypes:
              UIUserNotificationTypeAlert|
              UIUserNotificationTypeBadge|
              UIUserNotificationTypeSound categories:nil]];
        }
        
    }
    
    return YES;
}

三. 处理接受到通知后的回调

1. 遵守协议

@interface AppDelegate () <UNUserNotificationCenterDelegate>

2. 本地通知回调

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification NS_AVAILABLE_IOS(4_0) {
    
    UIAlertView *alert = [[UIAlertView alloc]
                          initWithTitle:notification.alertTitle
                          message:notification.alertBody
                          delegate:self
                          cancelButtonTitle:@"确定"
                          otherButtonTitles:nil,
                          nil];
    [alert show];

}

alert提示通知内容

3. 前台通知回调

- (void)userNotificationCenter:(UNUserNotificationCenter *)center 
willPresentNotification:(UNNotification *)notification 
withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler 
__IOS_AVAILABLE(10.0) __TVOS_AVAILABLE(10.0) __WATCHOS_AVAILABLE(3.0){
    
    NSLog(@"应用在前台运行是接受到通知，会直接调用该方法");
    
}

应用正在运行时接到通知，你可以在这里自定义处理

⚠️注意：前台收到推送时不会有消息弹窗效果的

• 想有后台收到通知一样的弹窗效果，加入下面的代码。

completionHandler(UNNotificationPresentationOptionBadge | 
UNNotificationPresentationOptionSound | 
UNNotificationPresentationOptionAlert);

4. 后台通知回调

- (void)userNotificationCenter:(UNUserNotificationCenter *)center 
didReceiveNotificationResponse:(UNNotificationResponse *)response 
withCompletionHandler:(void(^)(void))completionHandler 
__IOS_AVAILABLE(10.0) __WATCHOS_AVAILABLE(3.0) __TVOS_PROHIBITED{
    
    NSLog(@"后台或者未启动时接受到通知，点击通知会调用该方法");
    
}

用户在app在后台或者未启动的时候，点击了通知，你可以在这里做自定义处理

四. 发送通知

- (void)startLocalPush {
    
    UILocalNotification *localNotification = [[UILocalNotification alloc] init];
    
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    formatter.dateFormat = @"yyyy-MM-dd HH:mm";
    NSDate *fireDate = [formatter dateFromString:@"2019-04-04 17:42"];
    [localNotification setTimeZone:[NSTimeZone defaultTimeZone]];
    localNotification.fireDate = fireDate;
    localNotification.repeatInterval = kCFCalendarUnitDay;
    localNotification.alertBody = @"移动考勤提醒您：下班啦，记得考勤打卡哦！

      事务千万条，打卡第一条，
      打卡不及时，发薪两行泪！";

    localNotification.alertTitle = @"考勤提醒";
    localNotification.soundName = UILocalNotificationDefaultSoundName;
    
    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}

fireDate：是指开始触发的时间点。
repeatInterval：是循环的时间，这是个枚举，不是填数字的！！！

        NSCalendarUnitEra                = kCFCalendarUnitEra,

应有尽有，自己选。
