[iOS Jailbreak development VII] using IOSOPENDEV to develop springboard tweat

Personal Original, reprint please indicate source:Cnblogs.com/jailbreaker

Tweat can be understood as the "plug-in" program, you can do some hooks, iOS patching features, here we use the Iosopendev provided by the Logos Tweak template development.

Once created, you can see a. xm file, here is where we need to heap the code, and. MM will automatically generate content based on. XM, no need to enter it manually

-(void) applicationdidfinishlaunching: (ID) application

Look at the method name and determine the method that is executed after SB is loaded, and modify the. xm file.

Look at the. mm file, which is automatically generated based on the. XM content:

Finally build into Deb, upload source space or dpkg installation, the previous posts are detailed, no longer repeat. After restarting SB, you will see:
