Solution 1: Use MobileTerminal or OpenSSH plug-in to help us solve the problem.
Find MobileTerminal or OpenSSH on Cydia and install it. Then enable MobileTerminal or OpenSSH and run "uicache". Then, you will find that the APP icons that disappear have been reproduced on a daily basis.
Solution 2:
PP assistant and other tools connect to the computer and change the names of the following two files.
1./var/mobile/Library/Caches/tore com.apple.LaunchServces-056.css
2./var/mobile/Library/Caches/com. apple. mobile. installation. plist
If we change com.apple.launchservces-056.css tore to com.apple.LaunchServces-056.css tore_appbak
Change com. apple. mobile. installation. plist to com. apple. mobile. installation. plist_appbak.
The benefit of modifying the name is that we can directly change the names of the two files next time.
Reminder
A friend tested all the methods I introduced, but he still could not solve her problem, later, her solution was to delete apps without icons and re-install a new APP in Cydia, which solved the problem. In fact, this is also a good solution, as long as you are willing to work hard, there are many solutions.
