我们必须将C#代码转换为Objective-C代码,而我很难解决如何创建一个不带参数的构造函数,而另一个带2个参数的构造函数.
这是我要转换的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;
        }
        }
}

}

到目前为止,这是我对目标C所不确定的,甚至不确定它是否正确

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

@public Account()
   }

开放给我任何帮助,丹尼,非常感谢

解决方法:

您只需提供两个初始化程序,它们采用的一般形式为：

@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
