結(jié)構(gòu)字段的鍵的取值
CAAnimation供支持使用關(guān)鍵路徑訪問選擇的結(jié)構(gòu)字段。這在為動(dòng)畫關(guān)鍵路徑指定結(jié)構(gòu)字段的時(shí)候非常有幫助,同時(shí)你可以使用setValue:forKeyPath:和valueForKeyPath來設(shè)置和讀取相應(yīng)的值撬码。
CATransform3D公開如下的字段:
結(jié)構(gòu)體字段???????????????? ? ? ? ?? 描述
transform.rotation.x????????????? The rotation, in radians, in the x axis.
transform.rotation.y????????????? The rotation, in radians, in the y axis.
transform.rotation.z??????????? The rotation, in radians, in the z axis.
transform.rotation????????????????? The rotation, in radians, in the z axis. This is identical to setting the rotation.z field.
transform.scale.x????????????????? Scale factor for the x axis.
transform.scale.y????????????????? Scale factor for the y axis.
transform.scale.z???????????????? Scale factor for the z axis.
transform.scale?????????????????? Average of all three scale factors.
transform.translation.x????????? Translate in the x axis.
transform.translation.y?????????? Translate in the y axis.
translation.z????????????????????????? Translate in the z axis.
translation??????????????????????????? Translate in the x and y axis. Value is an NSSize or CGSize.
CGPoint公開如下字段:
結(jié)構(gòu)體字段描述
x????????????????????????? The x component of the point.
y?????????????????????????? The y component of the point.
CGSize公開如下字段:
結(jié)構(gòu)體字段描述
width????????????????????? The width component of the size.
height???????????????????? The height component of the size.
CGRect公開如下字段:
結(jié)構(gòu)體字段描述
origin????????????????????? The origin of the rectangle as a CGPoint.
origin.x??????????????????? The x component of the rectangle origin.
origin.y???????????????????? The y component of the rectangle origin.
size?????????????????????????? The size of the rectangle as a CGSize.
size.width????????????????? The width component of the rectangle size.
size.height??????????????? The height component of the rectangle size
你不可以通過Objective-C 2.0的屬性方法來指定一個(gè)結(jié)構(gòu)字段的關(guān)鍵路徑儿倒。如下的代碼是無法正常執(zhí)行的:
myLayer.transform.rotation.x = 0;
相反你必須使用setValue:forKeyPath:或者valuForKeyPath:,如下:
[myLayer setValue:[NSNumber numberWithInt:0] forKeyPath:@"transform.rotation.x"];
