Reading a font from file and making it available to Cocoa

This is another programming related post. Say you have a true type font that’s not part of the OS font set in a file. You’ve read the contents of the file into memory and now want to make it available to Cocoa. How? Turns out that ATSUI comes to the rescue:

	ATSFontContainerRef container;
    OSStatus status = ATSFontActivateFromMemory((LogicalAddress)[fontData bytes],           // buffer with font data
                                                [fontData length],          // size of font data
                                                kATSFontContextLocal,       // for use only in this application
                                                kATSFontFormatUnspecified,  // reserved
                                                NULL,                       // reserved
                                                kATSOptionFlagsDefault,     // reserved
