Why can I install it directly without using the App Store? In this case, Apple's signature is usually used. Apple's signboard is a method that can be installed without the review of App Store and Apple and without jailbreaking.
Apple signature can be divided into enterprise signature, super signature and tf signature.
If you need to trust an enterprise certificate during installation, it is an enterprise signature.
If you need to download and install testflight, it is tf signature.
Without the above two steps, the possibility of using super signature is very high.

The difference between enterprise signature and tf signature

Stability: To sum up, the more important information for developers and users is that both corporate signatures and super-signatures will be cancelled. After cancellation, users can't continue to use it, and they need to re-sign and reinstall it, but tf signature will not be cancelled.
Price: Enterprise contracts are divided into * * * enjoyment version, independent version and ultra-stable version according to stability, of which * * * enjoyment version is the cheapest, with 200 cases, and ultra-stable version is the most expensive.
Super signature is charged according to the download volume, and each download is more than ten pieces, which is not suitable for applications with a large number of users.
Tf signature is a download link that can be installed 1w times. If you reach the limit, you need a new link with moderate price and the highest cost performance.
