1. The method recommended by Apple, that is, the archive function of practical xcode
Xcode menu bar->Product->Archive->Upload to App Store upload directly to iturns or export to local, and then upload through ApplicationLoader
Limitation: Personal development generally adopts this method, but it is a little troublesome when a certificate is used by many people. Generally, the provisioning profile+P12 file is used for real machine debugging when multiple people develop. The above method needs to enter the appleID when exporting the ipa package at the end, and then ask for it from the rest of the team. Using the provisioning profile+P12 real machine debugging method does not require the developer to know the appleID and password, and the password is generally placed with the leader;
2. Upload directly to iturns through Application Loader.
Step1: Create a new "Payload" folder, note that the name should be word-for-word;
Step2: Put your .app package into Payload, pay attention to the app name without any changes, just use the app name generated by xcode;
Step3: Right-click on the Payload folder and compress it into zip, and then change the suffix of the generated .zip file to .ipa.
