写纯Objective-C代码时,我们基本上遵守标准Objective-Cnamingrules,这些规则和C++的规则有很大的不同。比如Google的C++代码规范推荐变量名构词之间使用下划线隔开,而本文档推荐驼峰法,也是Objective-C社区的标准。 所有类,类别,方法,以及变量如包括缩写,则缩写部分使用全大写的缩写(Initialisms)形式。这遵守Apple的标准,比...
Variable declarations should be followed by an empty line to separate them from the rest of the code: structutsname name;if(-1== uname(&name))returnSYSINFO_RET_FAIL; Code that sets up the context forifandwhileconstructs should be separated fromifandwhileby a blank line, unless the body ...
A naming attribute from which an object distinguished name is formed. For most object classes, the naming attribute is the Common-Name. For example, a user object with its cn set to "Jeff Smith" might have a distinguished name of "CN=Jeff Smith,CN=Users,DC=Fabrikam,DC=com". Component ...

Multiple rules can be specified. The rule names must match the names given to any parsers created by mpc_new, otherwise the function will crash. The flags variable is a set of flags MPCA_LANG_DEFAULT, MPCA_LANG_PREDICTIVE, or MPCA_LANG_WHITESPACE_SENSITIVE. For specifying if the language ...
Naming Rules for Files The value is a string of case-insensitive characters without spaces. The file name formats are as follows: File name A file resides in the current working directory if the file name is in this format. The length of the file name ranges from 1 to 64. Drive + Path...
