     #结果是notEqual
     __Array
     Array对象是对C++中数组的封装。Array中的元素是Ref、可以存不同的数据类型。
     创建一个空数组，Array::create()
     增：add系列、addObject 删：removeXXX系列，代表removeObjectAtIndext() 改:replaceObjectAtIndex()  查：get系列、getIndexOfObject()
    
     __Dictionary
     创建字典对象，auto pDict = Dictionary::create()
     添加键值对，pDict->setObject(obj, "key");
     删除键对应的值， pDict->removeObjectForKey("someKey");
     查                 ，pDict->ObjectForKey("someKey");
     auto pDict = Dictionary::create();
     auto pV1 = String::create("V1");
     auto pV2 = String::create("V2");
     pDict->setObject(pV1, "key1");
     pDict->setObject(pV2, "key2");
     String *pStr1 = (String*)pDict->ObjectForKey("key1");
     String *pStr2 = (String*)pDict->ObjectForKey("key2");
     log("str1 = %s,str2 = %s", pStr1->getCString(), pStr2->getCString());
    #使用ObjectForKey获得的是Object对象，要强制类型转换为你确定的那个类型。
    Size、Rect、Point
    Size于Rect的区别是Size只有长宽的属性，而Rect还有个起始点属性，他们都是表示一块矩形区域。
    其中Rect最常使用的是用来判断某个点在不再这个矩形区域内。其实他们都是对象，不像OC中是结构体。
