【问题描述】：

我正在按照 UA 的 docs 实施 Urban Airship 的交互式通知。我已成功注册类别和操作，如下所示：

// Define category options foreground and none
UANotificationActionOptions optionsActions = ( UANotificationActionOptionForeground );
UANotificationActionOptions optionsNone = ( UANotificationActionOptionNone );
UANotificationCategoryOptions optionCategory = ( UANotificationCategoryOptionCustomDismissAction );

// Define cancel action for all categories
UANotificationAction *actionCancel = [UANotificationAction actionWithIdentifier: @"action_cancel"
                                                                          title: @"Cancel"
                                                                        options: optionsNone];

// Define post action for the post category
UANotificationAction *actionPost = [UANotificationAction actionWithIdentifier: @"action_post"
                                                                        title: @"Post"
                                                                      options: optionsActions];

// Actions of post category
NSArray<UANotificationAction *> *actionsPost = @[actionPost, actionCancel];

// Define the post category
UANotificationCategory *post = [UANotificationCategory categoryWithIdentifier: @"post_cancel"
                                                                      actions: actionsPost
                                                            intentIdentifiers: @[]
                                                                      options: optionCategory];

// Set the custom categories
[UAirship push].customCategories = [NSSet setWithArray:@[post]];

现在，我正在尝试使用这些按钮（发布和取消）构建应用内消息，当我设置消息的 buttonGroup 时，我的按钮已经出现。不幸的是，我无法弄清楚如何为每个按钮链接自定义操作，我不知道应该在消息的buttonActions 中传递哪个字典。

UAInAppMessage *message = [UAInAppMessage new];
message.displayType = UAInAppMessageDisplayTypeBanner;
message.position = UAInAppMessagePositionTop;

message.duration = 5.0;

message.alert = @"My alert"
message.primaryColor = [UIColor whiteColor];
message.secondaryColor = [UIColor blackColor];

UAInAppMessaging *inAppMessaging = [UAInAppMessaging new];

[message setButtonGroup: @"post_cancel"]; // this line ensure that my in-app messaging add my two registered buttons
[message setButtonActions: /* WHICH DICTIONARY SHOULD I PASS? */ ];

dispatch_async(dispatch_get_main_queue(), ^{
    [inAppMessaging displayMessage: message];
});

谢谢。

【解决方案1】：

它需要一个按钮 ID 字典到动作名称到值的映射。示例：

@{
  @"action_cancel":
       @{
           @"my_custom_action_name": @"custom action value",
           @"another_action_name": @(YES)
       },

   @"action_post":
       @{
           @"some_other_action_name": @"some other action value"
       }
}

当点击应用内的action_cancel 按钮时，这将运行my_custom_action_name 和another_action_name。
