你好，可执行文件能砸壳成功，但是.framework砸壳不成功，请问这个有好的解决方案吗？

设备：iPhone6 用的checkra.in越狱的，系统12.4.5， 砸壳APP是喜马拉雅6.6.66版本

错误日志呢

leroyli commented 4 years ago

没有错误日志，命令是执行成功的，但是用otool查看framework还是加密的，只有二进制是解密的，拖多monkeyDev也是提示framework未解密

我这边测了下这个app，没啥问题的

xia0 ~ $ otool -l XMNetworkRequest.decrypted | grep crypt
XMNetworkRequest.decrypted:
     cryptoff 16384
    cryptsize 98304
      cryptid 0

你是用的最新版吗

leroyli commented 4 years ago

是最新版，如果你测试没问题那估计是我的某个步骤有问题，我再多尝试几遍，感谢
