There are several classes that are present on both Mac OS X and iPhoneOS, but the corresponding documentation are not found on the iPhoneOS.
Class | Possible reason for being undocumented |
---|---|
NSAffineTransform | CGAffineTransform is used instead. |
NSUnarchiver and NSArchiver | Deprecated — use NSKeyedUnarchiver and NSKeyedArchiver instead. |
NSPointerFunctions, NSHashTable and NSMapTable | No garbage collection on iPhoneOS. |
NSHost | Who knows? |
NSTask | SDK-compatible programs are not supposed to open other executables. |
NSPortMessage | SDK-compatible programs are not supposed to perform IPC. (Although NSMessagePort is documented.) |
NSProtocolChecker | Distributed objects are not available on the iPhoneOS. |

Autorelease pool debugging. |
NSUnbufferedIO[3] | Use unbuffered IO stream. |
NSWarnAboutOldStyleArchiverMethods | Warn about old style (non-keyed) archiver methods. |
