        NSString *str = @"Person";
        Class class = NSClassFromString(str);
        Person *person = [[class alloc] init];
        
        
        //Class变成字符串
        NSString *name = NSStringFromClass([Person class]);
        
        //方法反射
        NSString *method = @"test1";
        SEL selector = NSSelectorFromString(method);
        [person performSelector:selector];
        
        //将sel转化为字符串
        NSString *method1 = NSStringFromSelector(selector);
        
        [person release];
        
    }
    return 0;
}

Person和 Student只是定义了test1和test2方法而已
