Troubleshooting for iOS real machine debugging that cannot connect to the network

Troubleshooting for iOS real machine debugging that cannot connect to the network

Development Environment:

MacOS 10.12.1Xcode 8.1Qt 5.8 gSOAP 2.8
IPhone 6 S + iOS 10.1.1   Problem:I used Qt Quick to write a cross-platform application. It runs normally in Win10, Android, and macOS. However, when I connect to the iOS real machine for debugging, gSOAP Always Returns Error Code 28 when calling Webservice, I have been searching for errors related to SOAP_DIME_END according to the gSOAP error code table below Baidu.

It cannot be solved, so I downloaded the iOS 10.0 Simulator and ran it on the iOS virtual machine. There is no problem, indicating that it may be a problem with the system permissions of the real machine. Because my mobile phone card is placed on my Mate8, there is no card on the iPhone development machine, and it is connected to WIFI, I suddenly thought, should I try to plug the card into the iPhone development machine. After the card is inserted, the mobile phone immediately prompts whether the network is allowed. After you agree, you can connect to the Internet. Then I can see my application in [use wireless LAN and cellular mobile app. As a matter of fact, I mentioned a lot of nonsense, but I just recorded the process of filling in holes that I tried and put my heart at ease for a long time yesterday. All in all, if you are debugging iOS apps on a real machine, you 'd better plug in your SIM card. I saw a related post this morning, as follows:
