When debugging with the real machine, every time you run the app will pop up this box, click OK, run again no problem. Just beginning to feel nothing, but is more than a few times, to later, feel that it is also a waste of time, serious impact on development efficiency, after searching the internet over, decided to write the solution here, so that other people encounter this problem, there is a viable solution.
Reason:
Modified the Build Settings→packagin→produce Name. Modify this primarily to modify the app's names on the home screen, because most people use English names when they set up the project, but the app's name is generally Chinese, so many will modify this property.
Solution Solutions
Do not modify this property, there is an alternative way to modify the name of the app on the home screen. Open the project's Infor.plist file, add a line (Bundle display name) and set the value to the name of your app.
OK, everything's okay. This hateful dialog box will never pop up again in the future.
