帮助与理解C＃代码移植到Objective-C [英] Help with understanding C# code and porting to Objective-C

问题描述

好吧，我有这个原型，被写了有人在C＃else和我试图把它变成的Objective-C。现在，我还没有与C＃任何正式的经验，所以我不知道这一切呢。我明白的前三个变量，但我跑成什么了第四和第五行（C_DATA）正在做的问题。是第四个宣布方法，然后第五定义它还是发生了什么？ ！感谢您的帮助。

 公共类C_DATA {
公共双重价值; 
公众诠释标签; 
公众诠释身份证; 
公共C_DATA（）{} 
公共C_DATA（双VAL）{
值= VAL; 
} 
} 
  

解决方案

的第四和第五行是在C＃构造函数。他们是等价于[[C_DATA的alloc]初始化]在Objective-C链。 C＃允许你超载基础上，他们采取的参数的构造函数。这相当于具有Objective-C的两种不同的初始化方法：

  @interface CDATA出现：NSObject的
 {
双重价值; 
 INT标签; 
 INT ID; 
} 
 
 @财产双重价值; 
 @property INT标签; 
 @property INT ID; 
 
  - （id）的初始化; 
  - （ID）initWithValue：（双）值; 
 
 @end 
  

Ok, I have this prototype that was written by someone else in C# and I'm trying to put it into Objective-C. Now, I haven't had any formal experience with C# yet, so I don't know everything about it yet. I understand what the first three variables are, but I'm running into problems with what the fourth and fifth lines (c_data) are doing. Is the fourth declaring a method and then the fifth defining it or what's happening? Thanks for your help!

public class c_data {
    public double value;
    public int label;
    public int ID;
    public c_data() { }
    public c_data(double val) {
        value = val;
    }
}

解决方案

The fourth and fifth lines are constructors in C#. They are the equivalent to [[c_data alloc] init] chains in objective-c. C# allows you to overload constructors based on the parameters they take. This is equivalent to having two different initialization methods in Objective-C:

@interface CData : NSObject
{
   double value;
   int label;
   int ID;
}

@property double value;
@property int label;
@property int ID;

-(id) init;
-(id) initWithValue:(double)value;

@end
