科尔多瓦katzer插件后台模式不工作在iOS-9科尔、插件、后台、模式

2023-09-14 23:08:05 作者:一生就爱浪

在我的离子/ angularjs应用程序,我使用 https://github.com/katzer /利于让一个后台我的应用程序科尔多瓦-plugin的背景模式/ 。

in my ionic/angularjs application I use https://github.com/katzer/cordova-plugin-background-mode/ for backgrounding my application.

它在iOS-8,但随着新的iOS-9它不工作更多的工作安静好。我做了一些测试,它看起来像应用程序是真正在后台运行,但用户没有得到关于它的信息。在iOS-8我得到YourApp使用您的位置或者类似的东西在屏幕顶部的消息。在iOS-9这个信息丢失。

It's working quiet well on iOS-8 but with the new iOS-9 its not working any more. I did a few tests and it looks like the app is really working in the background but the user gets no information about it. On iOS-8 I get a message like "YourApp is using your location" or something like that on top of the display. On iOS-9 this message is missing.

难道有人用这个插件同样的经历?

Did someone the same experience with this plugin?

推荐答案

我发现有对iOS9一些变化的核心位置功能:allowsBackgroundLocationUpdates在CLLocationManager在iOS9

I found out that there are some changes in core location functions on iOS9: allowsBackgroundLocationUpdates in CLLocationManager in iOS9

就像在后建议我增加默认属性allowsBackgroundLocationUpdates使用对org.apache.cordova.geolocation插件值YES。

Like suggested in the post I add a default property allowsBackgroundLocationUpdates with the value YES to the org.apache.cordova.geolocation plugin.

随着CDVLocation.m此修复它位于 /plugins/org.apache.cordova-geolocation/src/ios / 现在它工作。

With this fix on CDVLocation.m which is located in /plugins/org.apache.cordova-geolocation/src/ios/ it now works.

要带上它工作我删除平台IOS与科尔多瓦平台删除IOS 科尔多瓦平台添加的ios 回来,它建立了新的插件。

To bring it to work I removed platform ios with cordova platform remove ios and added it again with cordova platform add ios back so it builds the plugins new.

现在我又得到显示屏上的蓝条: - )

Now I'm getting the blue bar on the display again :-)

此修补程序将打破iOS和LT的地理位置支持; 9.0。把它与旧版本的工作比9.0使用本CDVLocation.m文件:

This fix will break the geolocation support on iOS < 9.0. To bring it to work with older versions than 9.0 use this CDVLocation.m file:
