如何拆分目标c函数定义?

在典型的Objective-C样式中,跨越多行的方法通常以冒号对齐,以使其更具可读性:

-(id) initWithBsType:(NSInteger)buysell
         AccountCode:(NSString *)c_acc_code
            password:(NSString *)password
        exchangeCode:(NSString *)ecode
         productCode:(NSString *)product
           orderType:(NSString *)otype
               price:(NSString *)price
                 qty:(NSString *)qty
           reference:(NSString *)ref
     enablePriceWarn:(BOOL)enablepw
     enableApprvWarn:(BOOL)enableaw
       orderValidity:(NSString *)validity;

看到长长的参数列表,我想知道调用函数是什么样子的。。。可能很长。

我建议使用structs,并可能将XML的读取拆分为更多方法,例如:

typedef struct {
    /* ... */
} Order;

// extend the xml-reader for clean seperation, 
// seperate into multiple methods if too big
-(BOOL) readOrder:(Order*);

-(id) initWithOrder:(Order*)order;
