NSString到NSDecimalNumber的目標C轉換

Question

有人可以說我把NSString轉換爲NSDecimalNumber

unsigned long long order;

 if (i==1) { 

      order = [feeArray objectAtIndex:0]; 
     } 
     if (i==2) { 
      order = [amountArray objectAtIndex:0]; 
     } 

在此先感謝

Answer 1

您可以使用NSDecimalNumber的decimalNumberWithString初始化從字符串

Answer 2

轉換試試這個：

NSString *order = @""; 
if (i==1) { 
    order = [feeArray objectAtIndex:0]; 
} 
if (i==2) { 
    order = [amountArray objectAtIndex:0]; 
} 

NSDecimalNumber *decimal = [NSDecimalNumber decimalNumberWithString:order];
