點擊本地通知不會被觸發

Question

在iOS的10.3我加入的代碼，到AppDelegate：

@interface AppDelegate() { 
    UNUserNotificationCenter *center; 
} 

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

    center = [UNUserNotificationCenter currentNotificationCenter]; 
    UNAuthorizationOptions options = UNAuthorizationOptionAlert + UNAuthorizationOptionSound; 
    [center requestAuthorizationWithOptions:options 
          completionHandler:^(BOOL granted, NSError * _Nullable error) { 
           if (!granted) { 
            DLog(@"Something went wrong"); 
           } else { 
            DLog(@"Access Granted") 
           } 
          }]; 

    return YES; 
} 

我輕按通知，但該方法波紋管不叫。

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification

對於註冊在AppDelegate和使用的通知委託UNUserNotificationCenterDelegate通知進口UserNotifications/UserNotifications.h框架，以響應通知時，通知領取。

@interface AppDelegate()<UNUserNotificationCenterDelegate> 

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 
    // Override point for customization after application launch. 

    //Notification Setup. 
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 10.0) { 
     UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; 
     center.delegate = self; 
     [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error){ 
      if(!error){ 
       [[UIApplication sharedApplication] registerForRemoteNotifications]; 
      } 
     }]; 
    } else { 

     //register to receive notifications 
     UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound) categories:nil]; 
     [[UIApplication sharedApplication] registerUserNotificationSettings:settings]; 

    } 


    return YES; 
}
