有没有办法在 Xcode 中设置一个非默认的预编译头文件?例如,我可以将其设置为 SomeOtherHeader.h,而不是 Project_Prefix.pch 作为预编译头文件吗?
选择目标,选择 Build Settings,搜索 Prefix Header 并更改设置
在 XCode 6.1 中,它位于 Build Settings > Apple LLVM 6.0 - Language
在这里,我想打印“$”符号。怎么做?
#!/perl/bin/perl print <<EOF; This sign $ is called dollar It's a multiline string EOF
这给了我结果。
