推荐答案

就像其他人提到的那样，您可以使用 NSString的成员函数 componentsSeparatedByString:或 componentsSeparatedByCharactersInSet:

As others have mentioned, you can use NSString's member function componentsSeparatedByString: or componentsSeparatedByCharactersInSet:

作为一种替代方法(用于更强大的标记化)，请查看Objective-C

As an alternative (for more powerful tokenizing), look into the Objective-C NSScanner class in the foundation framework of Mac OS X.

您可以执行以下操作:

NSString *str = "drwxr-xr-x    9 0  ... ";
NSScanner *scanner = [NSScanner scannerWithString:str];

为了获取字符串形式的每个令牌，请使用 NSScanner的 scanUpToCharactersFromSet:intoString:成员函数.

In order to obtain each token in string form, use NSScanner's scanUpToCharactersFromSet:intoString: member function.

NSString *token = [NSString string];
NSCharacterSet *div = [NSCharacterSet whitespaceCharacterSet];
[scanner scanUpToCharactersFromSet:div intoString:token];
// token now contains @"drwxr-xr-x"

随后对上面的调用将返回9、0，依此类推.

Subsequent calls to the above would return 9, 0, and so on.

注意:上面的代码尚未经过测试.

Note: the code above has not been tested.
