很实用的IPHONE完美实现自定义软键盘(IPHONE perfect realization of very useful custom keyboard)

参考Apple Coding Guidelines for Cocoa, Google Objective-C Style Guide, Three20 Source Code Style Guildelines，并结合自己的实际情况总结了一份编码规范。自己在实行的过程中确实感觉到代码更加清晰了，看上去也“专业”了。希望对编码尚不规范的童鞋有所帮助。(Reference Apple Coding Guidelines for Cocoa, Google Objective-C Style Guide, Three20 Source Code Style Guildelines, and combined with their own summary of the actual situation of a coding standard. Themselves in the process of implementation of the code do feel more clear, and looked " professional" the. Coding not want to help regulate the children' s shoes.)
