我今天尝试lldb去调试支付宝与高德地图，按照 狗神的实战：干掉高德地图7.2.0版iOS客户端的反动态调试保护文章，但是debugserver -x backboard 一直提示Segmentation fault: 11，会是什么原因呢？麻烦解答 谢谢！

debugserver -x backboard *:1234 /var/mobile/Containers/Bundle/Application/72601192-8897-47A6-ADCC-6F48FA54C22E/AMapiPhone.app/AMapiPhone

debugserver-@(#)PROGRAM:debugserver PROJECT:debugserver-340.3.51.1
for arm64.
Segmentation fault: 11

现在貌似是
-x spring
了？

感谢狗神回复~
我尝试了spring，以下是提示. 我看不太懂(╯□╰), 狗神能帮忙看下么~~
$ debugserver -x spring *:1234 /var/mobile/Containers/Bundle/Application/C60AF8CD-57F6-4A02-A9C1-5F07BABD0CA4/AlipayWallet.app/AlipayWallet

error: invalid TYPE for the --launch=TYPE (-x TYPE) option: ‘spring’
Valid values TYPE are:
auto Auto-detect the best launch method to use.
posix Launch the executable using posix_spawn.
fork Launch the executable using fork and exec.
backboard Launch the executable through BackBoard Services.
frontboard Launch the executable through FrontBoard Services.

狗神, 我尝试了, debugserver -x posix *:1234 /var/mobile/Containers/Bundle/Application/C60AF8CD-57F6-4A02-A9C1-5F07BABD0CA4/AlipayWallet.app/AlipayWallet

然后解决了~ 谢谢

@snakeninny 狗神打扰了, 还有一个问题。 通过image list -o -f，取到App第二列的值, 现在取到的值跟书上的有字长度差别，现在都是这么长的十六进制么，0x000000000008c000.

还有狗神怎么来取方法的地址 我一直没太明白O_O … 0x000000000008c000-0x00000001000936c0 = ? (这个是在命令行输入么, 但是输入了也没任何结果)
