iOS 的本地通知在 objectiveC 中不起作用

Question

我正在尝试使用

iOS

触发

ObjectiveC

的本地通知。我不能使用

Swift

因为

react native's

新架构不支持它。

在我的 AppDelegate.m 文件中，我添加了以下代码

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

    
    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
    UNAuthorizationOptions options = UNAuthorizationOptionAlert + UNAuthorizationOptionSound;
    [center requestAuthorizationWithOptions:options
     completionHandler:^(BOOL granted, NSError * _Nullable error) {
      if (!granted) {
        NSLog(@"Something went wrong");
      }
    }];
    [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
      if (settings.authorizationStatus != UNAuthorizationStatusAuthorized) {
        // Notifications not allowed
      }
    }];

    return YES;
}

在我的按钮操作中，我调用下面的代码

- (IBAction)clickMe:(id)sender {
   

    UNMutableNotificationContent *content = [UNMutableNotificationContent new];
    content.title = @"Don't forget";
    content.body = @"Buy some milk";
    content.sound = [UNNotificationSound defaultSound];
    UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger
      triggerWithTimeInterval:1 repeats:NO];
    NSString *identifier = @"UYLLocalNotification";
    UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:identifier
                                                                          content:content trigger:trigger];
    UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter];
    [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
      if (error != nil) {
        NSLog(@"Something went wrong: %@",error);
      }
    }];


}

我想一按下按钮就触发通知
