breakpoint

• 概述
  • 用b或breakpoint加断点
    • 添加方式
      • 通过地址

        b <someAddress>
        breakpoint set -a <someAddress>
        breakpoint set --address <someAddress>
        

        • 举例

          breakpoint set -a 0x1102d3348
          breakpoint set --address 0x1830c6a80
          

      • 通过函数名

        b <someFunctionName>
        breakpoint set -n <someFunctionName>
        breakpoint set --name <someFunctionName>
        

        • 举例

          b objc_alloc_init
          breakpoint set --name "-[NSString stringByAppendingString:]"
          breakpoint set --name "-[AAUISignInController _performAuthenticationForAccount:serviceType:inViewController:completion:]"
          

    • 额外条件 = 辅助条件
      • 条件判断

        breakpoint set --name <someFunctionName> --condition <someConditionExpression>
        

        • 举例

          breakpoint set --name foo --condition '(int)strcmp(y,"hello") == 0'
          br s -n foo -c '(int)strcmp(y,"hello") == 0'
          br s -n "objc_alloc_init" -c '(bool)[NSStringFromClass($x0) isEqualToString: @"AADeviceInfo"]'
          br s -n "objc_alloc_init" -c '(int)strcmp((char *)class_getName($x0),"AADeviceInfo")==0'
          br s -n "objc_alloc_init" -c '(int)strcmp((char *)object_getClassName($x0),"AADeviceInfo")==0'
          

      • 指定模块=库

        br s -n <someFunctionName> -s <libFileName>
        br s -n <someFunctionName> --shlib <libFileName>
        

        • 举例

          br s -n "___lldb_unnamed_symbol972" -s libMobileGestalt.dylib
          br s -n "___lldb_unnamed_symbol972" --shlib libMobileGestalt.dylib
