问题
I make a tweak that works in backboardd, if I just respring after install it, it doesn't work, I have to restart the my iPhone entirely. Are there any other better ways need not restarting device?
回答1:
You can execute this in your postinst script if you are installing your tweak as debian package (*.deb)
launchctl stop com.apple.backboardd
Backboard will restart automatically and cydia-substrate should be able to inject your tweak in it.
回答2:
Note: since you say that you're using iOSOpenDev to create your tweaks, there's another option, altho the postinst file works fine, too.
Add another post-install command to the custom build script that iOSOpenDev will have created for your project.
You should already see this under the Target->Build Phases->Run Script:
Just add the following line where the arrow is (line 2):
/opt/iOSOpenDev/bin/iosod run -h ${iOSOpenDevDevice} 'su mobile -c uicache'
Note that this requires the UIKit tools package from Cydia to be installed. (to run uicache)
You should also have a user-defined Build Setting setting iOSOpenDevDevice equal to your device's IP address, so the installation can occur via Wi-Fi.
