    NSString *string1 = @"A,B,C,D";

    NSArray *array1 = [string1 componentsSeparatedByString:@","];

    NSLog(@"%@", array1);

    

    //字符串“A~B^C|D”由多个符号间隔组成，需要拆分成A、B、C、D

    NSString *string2 = @"A~B^C|D";

    NSArray *array2 = [string2 componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"~^|"]];
