施工人员从C#到Objective-C的代码

我们必须将C#代码转换为Objective-C代码，我很难弄清楚如何创建一个没有参数的构造函数，而另一个有两个参数。 这是我试图转换的C代码：

     namespace Account
{
class Program
{

    public class Account
    {

        private double balance;
        private int accountNumber;

        public Account()
        {
            balance = 0;
            accountNumber = 999;
        }

        public Account(int accNum, double bal)
        {
            balance = bal;
            accountNumber = accNum;
        }
        }
}

}

这就是我到目前为止对目标C的看法，我甚至不确定它是否正确

     @interface classname : Account 
   {
@private double balance;
@private int accountNumber;

@public Account()
   }

欢迎任何我能得到的帮助非常感谢，Danny

Objective C与其他语言有点不同。与其他语言相比，它的语法更奇怪。虽然从我所看到的来看，你似乎还没有对objective-c了解多少。我建议你看看苹果的文档，或者买一本书来真正了解objective-c语法是如何工作的。学习语法应该不会花太长时间，但以下是您应该如何做到这一点

@interface NSObject : Account
{
@private
double balance;
int accountNumber;
}
-(void)account; //No Arguements
-(void)account:(int)accNum withBalance:(double)bal; //2 Arguements

@implementation Program

-(void)account
{
balance = 0;
accountNumber = 999;
}

-(void)account:(int)accNum withBalance:(double)bal
{
balance = bal;
accountNumber = accNum;

}

您只需提供两个初始值设定项，它们采用一般形式：

@interface MONAccount : NSObject
@private
    double balance;
    int accountNumber;
}

/* declare default initializer */
- (id)init;

/* declare parameterized initializer */
- (id)initWithAccountNumber:(int)inAccountNumber balance:(int)inBalance;

@end

@implementation MONAccount

- (id)init
{
    self = [super init];
    /* objc object allocations are zeroed. the default may suffice. */
    if (nil != self) {
        balance = 0;
        accountNumber = 999;
    }
    return self;
}

- (id)initWithAccountNumber:(int)inAccountNumber balance:(int)inBalance
{
    self = [super init];
    if (nil != self) {
        balance = inBalance;
        accountNumber = inAccountNumber;
    }
    return self;
}

@end
