In IOS 8, Apple http://www.aliyun.com/zixun/aggregation/18736.html "> allows users to have more granular control over the location of an application and better protect their privacy." In IOS 7, users can turn on or off an application's positioning service, but users cannot specify how the application can be licensed. Apple added a new option to the app's location-based services in IOS 8--when users are using apps, they can get the user's location information.
Although this new option still allows applications to use the background positioning feature, this option is not valid if the user is not started in the application. That is, the user's location can be accessed even in the background if the user is allowed access to the application in the application.
This new licensing change also changes the notification of location requests:
First, Apple now requests applications in the first authorization application to explain why it is necessary to request the use of user locations. The photo app for IOS 8, for example, tells the user, "use the current location to search nearby photos."
Second, access to the "use" authorization of the application, tracking users will be at the top of the screen display a banner, users click the banner to enter the application.
Third, if the user allows the "always" access location, then every few days it will be a pop-up dialog box to remind users of the application has been in the background to use the user location, continue to allow use. The application displays the arrows for the positioning service at the top of the screen, regardless of the level of user's positioning authorization for the application.
The new feature, which Apple introduced to developers at the end of the WWDC workshop, said it was for users to "get full control of location use". Of course, it also requires developers to adjust their applications, but Apple's move is clearly in line with their trends to provide users with a more comfortable experience.
