Every generation of iOS system will encounter new loopholes at the beginning of push. iOS 12 official version has the limit of cracking the screen time at the beginning of the push. Today, another user found that his iPhone is upgrading iOS 12 After that, the app store in the App Store is very different from the actual installed storage. Take Facebook as an example. The app size displayed on the App Store's download interface is 519MB. But after downloading it, if you look at the iPhone's storage space again, Will find that its actual occupancy is only 316MB.
It is reported that the App Store provides the iPhone device with the code and resources needed to run the application on its device through the app thinning process. When developing the app, the developer will create different programs for all the devices supported by the app. Package; but when submitting its app to Apple, it submits a generic package that contains the App code and resources for all supported devices.
At present, developers have confirmed that the App Store incorrectly displays the general package size of some applications as the size of the app, rather than the size of the package required for the currently used device. This is what leads Facebook (and some other applications). The reason why the displayed app size does not match the actual one. Currently, the developer has reported the vulnerability to Apple, and Apple has not yet responded.
