objective c - Dynamically scale and translate shape -

i drawing series of uibezierpath's, of have different sizes , locations. scale each shape specific size , move specific location on uiview. working cgaffinetransformation right now. becoming messy, location , size not work shapes.

is there way can scale uibezierpath specific size , translate (move) specific location work shapes? maybe there way set size , location of shape without having use transformations unaware of? shapes drawing different in size, jagged edges.

this doing far affinetransformations.

cgaffinetransform scale = cgaffinetransformmakescale(2.0f,2.0f);  [path applytransform:scale];  cgaffinetransform move = cgaffinetransformmaketranslation(-10, -10); [path applytransform:move]; 

where path uibezierpath.

is correct? values using (-10, 2.0f) examples.

what looking how apply affine transform bezier path. sure can, method:

- (void)applytransform:(cgaffinetransform)transform; 

this how structure defined:

struct cgaffinetransform {    cgfloat a;    cgfloat b;    cgfloat c;    cgfloat d;    cgfloat tx;    cgfloat ty; }; typedef struct cgaffinetransform cgaffinetransform; 

and fields meaning:

fields
a
entry @ position [1,1] in matrix.
b
entry @ position [1,2] in matrix.
c
entry @ position [2,1] in matrix.
d
entry @ position [2,2] in matrix.
tx
entry @ position [3,1] in matrix.
ty
entry @ position [3,2] in matrix.
