Xcode 与 iPhone 6 的连接丢失

Question

I know there are already some posts here talking about the same problem, which is, when run the app on device, Xcode shows Xcode lost connection to iPhone, Restore the connection to App.... , But my situation is a bit strange.

My app works perfectly on my iPhone 6S ( iOS 10.1 Beta 3 ) but on my iPhone 6 Plus ( iOS 10.0.2 ), the app will crash and Xcode shows that information. I read some posts here saying it might be because my app loads too many high resolution photos and the OS kill the process due to high memory use Lost Connection to "iPhone" , but what happened to me let me think -- Could it be a iOS issue??? Since on iOS 10.1 Beta 3 it has no problems. ( And when iOS 9 , no problems as well )

This really bothers me and if it is really an OS issue, then how to solve this? how do those big companies'app ( like Facebook ) avoid the OS issues when there is a new iOS version released ? I mean, the generally users don't have Beta version.

will be very appreciated if any answer or advice.

Answer 1

First make sure that you are not loosing physical connection . I means make sure that your usb cable is not breaking connection. If it is so then you gots exactly this error which you have mentioned in your question.

Second thing yes this issue can be produce because of large memory consumption (usually large images), in this case you have to resize images to display in your imageViews and you should use less memory . You should avoid to convert your image to NSData if it is not hardly needed. This shouldn't be a bug of latest ios but it should be your mistake somewhere to deal with data !
