How xcode generates ipa
To generate a binary file that can run on a real device, you need the corresponding pp file and certificate, and add the device ID. Novices will have a headache for these, but these are actually places where Apple is cautious. I won't go into details. If it can be generated normally, you will see. The application file has changed from red to black. Right-click to open and display in finder. Then drag the generated binary files into iTunes, and iTunes will package the binary files you dragged into ipa files and display them in iTunes.
