LongestCocoa

Objective-C程序员一定非常喜欢它详细的描述性命名风格。

SoWhatIsTheLongestMethodOrConstantNamesInCocoaFramework? （那么，Cocoa框架中最长的方法名或常量名是什么？）答案是：

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

longest.py可以帮你找出Objective-C项目中每种标识符中最长的10个。使用很简单：

git clone https://github.com/Quotation/LongestCocoa
cd LongestCocoa
python longest.py <到Objective-C项目目录的路径>

以下是iPhoneOS的结果：
