It should be noted that the review of the App Store is very strict, and many applications may not be successfully put on the shelves. Applications that can't be put on shelves can choose Apple signature, which can be divided into enterprise signature, super signature and tf signature.
Simply put, the difference between the three is that the price of enterprise signature is relatively cheap, and there is no limit on the number of installations. However, when installing, you need to trust the enterprise certificate first, which is weak in stability and easy to lose the signature. Super signature is stable, but individual developer account can only be added with 100 udid, which is expensive and convenient to install directly without trust certificate. Tf signature is actually a distribution model recognized by Apple, so it is extremely stable. Once it is on the shelves, it will basically not be cancelled, but you need to install Apple's official testflight first, and then install the application in testflight.
Thanks to the developer service platform, it supports enterprise signature, super signature, tf signature and online self-signature. Welcome to official website for consultation.
