将NSString的目标c转换为NSDecimalNumber

Question

任何人都可以说我将NSString转换为NSDecimalNumber

unsigned long long order;

        if (i==1) {

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

提前致谢

Answer 1

您可以使用NSDecimalNumber的{​​{1}}初始值设定项来转换字符串

Answer 2

试试这个：

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

NSDecimalNumber *decimal = [NSDecimalNumber decimalNumberWithString:order];
