对于推送通知：如何向警报视图添加操作以更改视图？ [英] For push notifications: how do I add action to alert view to change views?

问题描述

所以我有推送通知发送到我的应用程序。

So I have push notifications sending to my application.

触发警报的代码在我的应用程序委托文件中（我认为那应该在哪里去？）

The code that triggers the alert is in my app delegate file (I think thats where it is supposed to go?)

如何对警报按钮进行操作，以便可以更改为其他视图？

How do I make an action for my alert button so that I can change to a different view?

// Set Below code in your App Delegate Class... 

   - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
        // Call method to handle received notification
        [self apnsPayloadHandling:userInfo];
    }

    -(void) apnsPayloadHandling:(NSDictionary *)userInfo{
        // Example Payload Structure for reference
        /*
         remote notification: {
         acme1 = 11114;
         aps   =    {
         alert = {
         "action-loc-key" = "ACTION_BUTTON_TITLE";
         "loc-args" = ("MSG_TEXT");
         "loc-key" = "NOTIFICATION_DETAIL_PAGE";
         };
         badge = 10;
         sound = "chime";
         };
         }
