2.13、建议:关于方法的参数名

说明:方法参数名一般使用的前缀包括“ the ”、“ an ”、“ new ”。 示例:良好的风格:-(void)setTitle:(NSString*)aTitle;

Cocoa命名举例:

realPath

fullString

object

//类方法newStringnewArray良好的自定义方法命名风格:recipients = [email

recipients SortedByLastName ];newEmail = [CDCEmail email

WithSubjectLine :@"Extra Text"]; emails = [mailbox messages

ReceivedAfterDate :yesterdayDate];

当需要获取对象值的另一种类型的时候,方法命名的格式语法如下: [object

adjective +thing];[object adjective +thing+ condition ];[object adjective +thing+

input :input];

良好的自定义方法命名风格:capitalized = [name capitalized String];

- (void) setName:- (id) keyForOption:- (NSArray *) emailsForMailbox:-

-(CDCEmail *) emailForRecipients: (NSArray *) theRecipients;

-(NSString *) newName; (CDCOption *) anOption (CDCMailbox *) theMailbox;
