1, you can use Apple to sign ios super signature. Ios super signature is different from the traditional Apple signature, and the technical mechanism used by iOS super signature is also different from ordinary company signature, even more complicated. Therefore, the stability of IOS super signature is much better than that of Apple's corporate signature, and it has the characteristics of installing it once a year without losing the signature.

2. It is understood that there are two reasons for the stability of ios super signature. One is the complex and unique signature mechanism, and the other is the personal developer account used. In other words, the iOS super signature does not use the certificate generated by the Apple enterprise developer account, but uses the Apple personal developer account to create a description file for users to install.

3. Obtain the udid of the user's Apple device through this description file, then register the obtained udid under the personal developer account, then generate a description file for the ipa package to be signed by the user, and finally transmit it to the server, and use itms-services to realize the user's download. The whole super signature process is more complicated and stable than Apple's signature.
