推荐答案

像下面的代码一样使用NSScanner:

Use the NSScanner like in the following code:

  unsigned x;

[[NSScanner scannerWithString: s2] scanHexInt: &x];

当键入scanHexInt时，在扫描时停止并查看自己需要的那个-有很多从字符串中获取值的可能性....

when typing the scanHexInt stop at scan and see yourself which one you need - there are many possibilities to get values from strings....

您可能要使用scanlonglong ...将变量声明为long

You might want to use scanlonglong... having declared your variable as long
