如何实现 iOS8 交互通知

Question

我正在开发一个支持交互式通知的 iOS8 应用程序。但我不清楚交互式通知支持的功能以及如何发送/处理交互式通知。如果有人能举个例子，那对我很有帮助。

在此先感谢 :)

Answer 1

我想稍微扩展一下 Sourav Gupta 的回答。一旦你完成了 Sourav 解释的内容，你必须实现代表来接收推送通知操作。代表们是，

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void(^)())completionHandler {

// Handle actions of local notifications here. You can identify the action by using "identifier" and perform appropriate operations

     if(completionHandler != nil)    //Finally call completion handler if its not nil
         completionHandler();
}

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler {

// Handle actions of remote notifications here. You can identify the action by using "identifier" and perform appropriate operations

     if(completionHandler != nil)    //Finally call completion handler if its not nil
         completionHandler();
}

Answer 2

1. 首先您需要创建通知操作。
2. 其次，您需要创建通知类别并设置其操作。您可以设置两个上下文。 UIUserNotificationActionContextDefault 或 UIUserNotificationActionContextMinimal
3. 第三个你需要创建通知设置并分配上述类别
4. 第四步是创建本地通知并为其分配类别标识符。

[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
