!                              這三個(gè)屬性最多只能同時(shí)設(shè)置兩個(gè);
*                              他們之間的關(guān)系如下:
*                              如果同時(shí)設(shè)置了fromValue和toValue,那么動(dòng)畫就會(huì)從fromValue過渡到toValue;
*                              如果同時(shí)設(shè)置了fromValue和byValue,那么動(dòng)畫就會(huì)從fromValue過渡到fromValue + byValue;
*                              如果同時(shí)設(shè)置了byValue  和toValue,那么動(dòng)畫就會(huì)從toValue - byValue過渡到toValue;
*
*                              如果只設(shè)置了fromValue,那么動(dòng)畫就會(huì)從fromValue過渡到當(dāng)前的value;
*                              如果只設(shè)置了toValue  ,那么動(dòng)畫就會(huì)從當(dāng)前的value過渡到toValue;
*                              如果只設(shè)置了byValue  ,那么動(dòng)畫就會(huì)從從當(dāng)前的value過渡到當(dāng)前value + byValue.
*
*                              可以這么理解,當(dāng)你設(shè)置了三個(gè)中的一個(gè)或多個(gè),系統(tǒng)就會(huì)根據(jù)以上規(guī)則使用插值算法計(jì)算出一個(gè)時(shí)間差并
*                              同時(shí)開啟一個(gè)Timer.Timer的間隔也就是這個(gè)時(shí)間差,通過這個(gè)Timer去不停地刷新keyPath的值.
!                              而實(shí)際上,keyPath的值(layer的屬性)在動(dòng)畫運(yùn)行這一過程中,是沒有任何變化的,它只是調(diào)用了GPU去
*                              完成這些顯示效果而已.
*                              在這個(gè)動(dòng)畫里,是設(shè)置了要旋轉(zhuǎn)到的弧度,根據(jù)以上規(guī)則,動(dòng)畫將會(huì)從它當(dāng)前的弧度專旋轉(zhuǎn)到我設(shè)置的弧度.
*
*  @param duration             動(dòng)畫持續(xù)時(shí)間
*
*  @param timingFunction       動(dòng)畫起點(diǎn)和終點(diǎn)之間的插值計(jì)算,也就是說它決定了動(dòng)畫運(yùn)行的節(jié)奏,是快還是慢,還是先快后慢...

/** CAAnimationGroup
*
*  @brief                      顧名思義,這是一個(gè)動(dòng)畫組,它允許多個(gè)動(dòng)畫組合在一起并行顯示.比如這里設(shè)置了兩個(gè)動(dòng)畫,
*                              把他們加在動(dòng)畫組里,一起顯示.例如你有幾個(gè)動(dòng)畫,在動(dòng)畫執(zhí)行的過程中需要同時(shí)修改動(dòng)畫的某些屬性,
*                              這時(shí)候就可以使用CAAnimationGroup.
*
*  @param duration             動(dòng)畫持續(xù)時(shí)間,值得一提的是,如果添加到group里的子動(dòng)畫不設(shè)置此屬性,group里的duration會(huì)統(tǒng)一
*                              設(shè)置動(dòng)畫(包括子動(dòng)畫)的duration屬性;但是如果子動(dòng)畫設(shè)置了duration屬性,那么group的duration屬性
*                              的值不應(yīng)該小于每個(gè)子動(dòng)畫中duration屬性的值,否則會(huì)造成子動(dòng)畫顯示不全就停止了動(dòng)畫.
*
*  @param autoreverses         動(dòng)畫完成后自動(dòng)重新開始,默認(rèn)為NO.
*
*  @param repeatCount          動(dòng)畫重復(fù)次數(shù),默認(rèn)為0.
*
*  @param animations           動(dòng)畫組(數(shù)組類型),把需要同時(shí)運(yùn)行的動(dòng)畫加到這個(gè)數(shù)組里.
*
*  @note  addAnimation:forKey  這個(gè)方法的forKey參數(shù)是一個(gè)字符串,這個(gè)字符串可以隨意設(shè)置.
*
*  @note                       如果你需要在動(dòng)畫group執(zhí)行結(jié)束后保存動(dòng)畫效果的話,設(shè)置 fillMode 屬性,并且把
*                              removedOnCompletion 設(shè)置為NO;
