进入命令界面后的命令
1) 查看可用的平台
(lldb) platform list Available platforms: host: Local Mac OS X user platform plug-in. remote-macosx: Remote Mac OS X user platform plug-in. remote-ios: Remote iOS platform plug-in. remote-gdb-server: A platform that uses the GDB remote protocol as the communication transport.
2) 选择远程ios为 当前平台
(lldb) platform select remote-ios --sysroot /Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk Platform: remote-ios Connected: no SDK Path: "/Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk" 选项解释 --sysroot 指定SDK根目录(含有所有的远程系统文件) --version --build
3)连接到远程debugserver (Connect a platform by name to be the currently selected platform.
(lldb) platform connect connect://192.168.1.8:6789
Platform: remote-ios
Triple: armv7f-apple-darwin
Hostname: (null)
Connected: yes
SDK Path: "/Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk"
4) 连接到调试服务(Connect to a remote debug service)
process connect connect://192.168.1.8:6789
