Position(位置)的默认anchorPoint（描点）是（0.5，0.5）
anchorPoint(描点)的取值范围是0~1之间。

PS：示例的屏幕大小为480*320
文字的位置放在屏幕的正中。

C++关键代码：

[mw_shl_code=c,true] auto labela = LabelTTF::create ( "A","Arial", 31);
    labela->setPosition ( Point ( Vec2 (240 , 160 )));
    this->addChild ( labela, 1 );
    auto labelb = LabelTTF::create ( "B", "Arial", 31);
    labelb->setPosition ( Point ( Vec2 ( 240, 160 )));
    labelb->setAnchorPoint ( Vec2 ( 0, 0 ));
    this->addChild ( labelb,1);
    auto labelc = LabelTTF::create ( "C", "Arial", 31);
    labelc->setPosition ( Point ( Vec2 ( 240, 160 )));
    labelc->setAnchorPoint ( Vec2 ( 0, 1 ));
    this->addChild ( labelc,1);
   
    auto labeld = LabelTTF::create ( "D", "Arial", 31);
    labeld->setPosition ( Point ( Vec2 ( 240, 160 )));
    labeld->setAnchorPoint ( Vec2 ( 1, 0 ));
    this->addChild ( labeld,1);
    auto labele = LabelTTF::create ( "E", "Arial", 31 );
    labele->setPosition ( Point ( Vec2 ( 240, 160 )));
    labele->setAnchorPoint ( Vec2 ( 1, 1 ));
    this->addChild ( labele, 1 );[/mw_shl_code]
