Is there a list of pragmas supported in Xcode? I only know of #pragma mark. Where would I look to learn about any others?
GCC online manual, see here. Depending on your XCode settings, you can use GCC 4.0, 4.2, 4.4 (if present on your system) or even LLVM/GCC 4.2. Please refer to proper compiler version docs for specific information.
