A must-see when doing TF autographs! Testflight signed source fee list!!!

Apple TF signature is actually a way for iOS applications to be downloaded through Apple’s official product TestFlight. The original intention of IPATF signature is that Apple uses it for internal testing downloads of some apps before release. Taobao, Zhihu, and even Alipay will use this method to provide some customers with distributed downloads before the official release to avoid irreparable problems after the official release. At present, many products will use tf as a distribution method before being put on the shelves due to difficulties in putting them on the shelves and long review weeks.
