推荐答案

componentsSeparatedByString:类似于Java中的StringTokenizer.它将基于给定的分隔符将给定的字符串拆分为一个数组.例如

componentsSeparatedByString: is like StringTokenizer in Java. It splits the given string into an array based on the given separator. For example,

NSString *namesStr =  @"John;Michael;Jason";
NSArray *namesArray = [namesStr componentsSeparatedByString:@";"];

结果，namesArray将包含字符串@"John"，@"Michael"和@"Jason".

As the result, namesArray will contain the strings @"John", @"Michael" and @"Jason".
