Parse warning from didReceiveRemoteNotification:fetchCompletionHandler
提问by Arian Faurtosh
I am getting an error after adding this code from parse.com:
从 parse.com 添加此代码后，我收到错误消息：
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
if (application.applicationState == UIApplicationStateInactive) {
[PFAnalytics trackAppOpenedWithRemoteNotificationPayload:userInfo];
}
}
I don't really understand what is going on, but I am getting this warning in the log:
我真的不明白发生了什么，但我在日志中收到了这个警告：
You've implemented -[ application:didReceiveRemoteNotification:fetchCompletionHandler:], but you still need to add "remote-notification" to the list of your supported UIBackgroundModes in your Info.plist.
你已经实现了 -[ application:didReceiveRemoteNotification:fetchCompletionHandler:]，但你仍然需要在你的 Info.plist 中你支持的 UIBackgroundModes 列表中添加“remote-notification”。
I think adding in your plist file UIBackgroundModes - remote-notificationwould fix the problem,
我认为添加你的 plist 文件UIBackgroundModes - remote-notification可以解决这个问题，
But when I do that, it changes the words to the follow:
但是当我这样做时，它会将文字更改为以下内容：
Required Background Modes-> App downloads content in response to push notifications
Required Background Modes-> App downloads content in response to push notifications
Which my app doesn't do, so I am confused as to why I am doing this in the first place.
我的应用程序没有这样做，所以我很困惑为什么我首先要这样做。

If you don't intend to fetch data in response to a remote notification I think you can implement this delegate method:
如果您不打算获取数据以响应远程通知，我认为您可以实现此委托方法：
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
e.g.
例如
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo {
if (application.applicationState == UIApplicationStateInactive) {
[PFAnalytics trackAppOpenedWithRemoteNotificationPayload:userInfo];
}
}
instead of the current one you're using.
而不是您正在使用的当前。

If you don't want to manually add key in your .plistfile then here's a graphical version of @MurraySagal's answer, follow the steps from 1 to 7 and you'll be done. :)
如果您不想在.plist文件中手动添加密钥，那么这里是@MurraySagal 答案的图形版本，请按照步骤 1 到 7 操作即可完成。:)
Note: If you can't read out the steps, you can zoom out your current tab by using combination of Command++(for zoom in) and Command+-(for zoom out). If Commandwon't work, you can try with Ctrl.
注意：如果您无法读出步骤，您可以使用Command+ +（放大）和Command+ -（缩小）的组合来缩小当前选项卡。如果Command不起作用，您可以尝试使用Ctrl.

I think @djshiow is not solving your problem.
我认为@djshiow 没有解决您的问题。
You need to add the following in your info.plist file:
您需要在 info.plist 文件中添加以下内容：
1) Add a new row and, on the left column, select Required background modes.
1) 添加一个新行，然后在左列中选择Required background patterns。
2) On Item 0 row, click on the right column and type: remote-notification. Press Enter.
2) 在 Item 0 行上，单击右列并键入：remote-notification。按 Enter。

In Xcode 6:
在 Xcode 6 中：
- In the Project Navigator click the project
- In the Projects and Targets list click the target.
- Click Capabilities
- Expand and turn on Background Modes
- Click Remote Notifications
- 在项目导航器中单击项目
- 在项目和目标列表中单击目标。
- 点击功能
- 展开并打开背景模式
- 单击远程通知
This will add the Required background modeskey and App downloads content in response to push notificationsvalue to info.plist.
这会将Required background modes键和App downloads content in response to push notifications值添加到info.plist.

When you use the new didReceive... method you are expected to do two things:
当您使用新的 didReceive... 方法时，您需要做两件事：
- Add the necessary entry in your plist
- Add a completion handler that will handle the event for handling the data
- 在 plist 中添加必要的条目
- 添加一个完成处理程序来处理处理数据的事件
If you do not want to download any data, you can add this to your didReceive... method
如果您不想下载任何数据，可以将此添加到您的 didReceive... 方法中
completionHandler(.NoData)
