然后函数会根据Elf32_ElfHeader的信息遍历每一个SectionHeader,同时判断是否有Elf32_SectionHeader.sh_name与”.got”相等,相等即保存其sh_addr GetElf32StringTabBaseFromfile是实现即是通过Elf头中的e_shoff,e_shstrndx和e_shentsize信息找到so文件中SectionHeader里面的.shstrtab

0, height: CGFLOAT_MIN)) 测试结果推断出的结论: UITableViewStyle为Grouped时,tableHeaderView = nil 前提条件下 1.没有实现sectionHeader 或sectionFooter代理(只实现一个也不行),所有系统下tableView顶部会有一个空白 2.同时实现了sectionHeader和sectionFooter代理,iOS13.2以下系统顶部有空白 ,iOS13.2及以上系统顶部无留白 3.同时实现了sectionHeader和sectionFooter代理,并且同时设置了sectionHeader和sectionFooter的预估高度为0,所有系统下

UIBarAppearance 2、tableView 增加sectionHeaderTopPadding属性,默认值是UITableViewAutomaticDimension,可能会使tableView sectionHeader

sectionHeaderLocationTop: 0, //页面滚动距离 scrollTop: 0, //是否悬停 fixed: false }, 此时我们需要的效果就实现了: sectionHeader
3.objdump可以在你不了解程序文件格式的情况下,读取 ELF header, program header table, sectionheader table 还有反汇编等功能。
