LongestCocoa

Programmers who write Objective-C must REALLY love its descriptive and verbose naming style.

SoWhatAreTheLongestMethodOrConstantNamesInCocoaFramework? Here are some superb ones:

• outputImageProviderFromBufferWithPixelFormat:pixelsWide:pixelsHigh:baseAddress:bytesPerRow:releaseCallback:releaseContext:colorSpace:shouldColorMatch:
• kCMSampleBufferConduitNotificationParameter_UpcomingOutputPTSRangeMayOverlapQueuedOutputPTSRange

Run python longest.py to discover the first 10 longest names for each identifier type. Below is the output from python longest.py iphoneos and python longest.py macosx.
