推荐答案

您可以从控制台(scanf 或其他)读取 char* 字符串，就像在常规 C 程序中一样.然后，使用 stringFromCString:withEncoding: 从中创建一个 NSString 对象.最后，使用NSString的integerValue函数来获取它的数值.

You can read in a char* string from console (scanf or whatever), like you would in a regular C program. Then, create an NSString object from it using stringFromCString:withEncoding:. Finally, use NSString's integerValue function to get it's numerical value.
