1. Failed to get connection from a remote gdb process.

將使用ldid導(dǎo)出的debugserver的debugserver.entitlements文件，如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>com.apple.springboard.debugapplications</key>
    <true/>
    <key>com.apple.backboardd.launchapplications</key>
    <true/>
    <key>com.apple.backboardd.debugapplications</key>
    <true/>
    <key>com.apple.frontboard.launchapplications</key>
    <true/>
    <key>com.apple.frontboard.debugapplications</key>
    <true/>
    <key>run-unsigned-code</key>
    <true/>
    <key>seatbelt-profiles</key>
    <array>
        <string>debugserver</string>
    </array>
    <key>com.apple.diagnosticd.diagnostic</key>
    <true/>
    <key>com.apple.security.network.server</key>
    <true/>
    <key>com.apple.security.network.client</key>
    <true/>
    <key>com.apple.private.memorystatus</key>
    <true/>
    <key>com.apple.private.cs.debugger</key>
    <true/>
</dict>
</plist>

需要修改成：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>com.apple.backboardd.debugapplications</key>
    <true/>
    <key>com.apple.backboardd.launchapplications</key>
    <true/>
    <key>com.apple.frontboard.debugapplications</key>
    <true/>
    <key>com.apple.frontboard.launchapplications</key>
    <true/>
    <key>com.apple.springboard.debugapplications</key>
    <true/>
    <key>com.apple.system-task-ports</key>
    <true/>
    <key>get-task-allow</key>
    <true/>
    <key>platform-application</key>
    <true/>
    <key>run-unsigned-code</key>
    <true/>
    <key>task_for_pid-allow</key>
    <true/>
</dict>
</plist>

重新ldid操作 給debugserver簽上權(quán)限即可

2. failed to get reply to handshake packet

通過(guò)usb-replay的方式連接debugserver，

 (lldb) process connect connect://localhost:10011

a. lldb窗口報(bào)錯(cuò)：

error: failed to get reply to handshake packet

b. debugserver窗口報(bào)：

error: rejecting incoming connection from ::ffff:127.0.0.1 (expecting ::1)

c. 解決方案：
把debugserver啟動(dòng)試設(shè)置的監(jiān)聽(tīng)

debugserver *:10011 -a  pid

改成為：

debugserver localhost:10011 -a  pid
